Internet-Draft MANET packet format June 2007
1. Introduction
This document specifies the syntax of a general purpose multi-message
packet format for information exchange between MANET routers.
Messages consist of a message header, which is designed for control
of message dissemination, and a message body, which contains protocol
information. Only the syntax of the message body is specified. All
syntactical entities, including messages and packets, are specified
using regular expressions.
This document specifies:
o A packet format, allowing zero or more messages to be contained
within a single transmission, and optionally including a packet
header. A packet with zero messages may be sent in case the only
information to exchange is contained in the packet header (such as
a "keep alive" sequence number).
o A message format, where a message is composed of a message header
and a message body.
o A message header format which allows a node to make forwarding
decisions based on the node's present state and the message
header, without inspecting and processing the message body, and
independently of the TTL or hop limit information in the IP
header. Message header information permits single- and multi-hop
message diffusion.
o A message body format, containing attributes associated with the
message or the originator of the message, as well as blocks of
addresses with associated attributes.
o An address block format, where an address block represents sets of
addresses in a compact (compressed) form.
o A generalized type-length-value (TLV) format representing
attributes. Multiple TLVs can be included and associated with a
packet, a message, an address, or a set of addresses.
The specification has been explicitly designed with the following
properties, listed in no particular order, in mind:
Parsing logic - the regular expression specification facilitates
generic, protocol independent, parsing logic.
Clausen, et al. Expires December 17, 2007 [Page 3]
Internet-Draft MANET packet format June 2007
Extensibility - packets and messages defined by a protocol using
this specification are extensible through defining new message
types and new TLVs. Existing protocol specifications using this
specification will be able to correctly identify and skip such new
message types and TLVs, while correctly parsing the remainder of
the packet and message.
Efficiency - when reported addresses share common bit sequences
(e.g. prefixes or IPv6 interface identifiers) the address block
representation allows for a compact representation. Compact
message headers are ensured through permitting inclusion of only
required message header elements.
Separation of forwarding and processing - duplicate detection and
controlled scope message forwarding decisions can be made using
information contained in the message header, without processing
the message body.

2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119. [1].
Additionally, this document uses the following terminology:
Packet - the top level entity in this specification. Packets are
transmitted over a single logical hop and are not forwarded. A
packet contains zero or more messages, and may contain a packet
header.
Message - the fundamental entity carrying protocol information, in
the form of addresses and TLVs. Messages are transmitted in
packets, and may be forwarded based on their header information.
Address - an address of the same length as the source IP address in
the IP datagram carrying the packet.
TLV - a Type-Length-Value structure. This is a generic way in which
an attribute can be represented and correctly parsed, without the
parser having to understand the attribute.
element - a syntactic entity defined in the regular expression
specification, represented using the notation <foo>.
<foo> - if <foo> is an 8 or 16 bit field then <foo> is also used to
represent the value of that field.
? - zero or one occurrences of the preceding element.
* - zero or more occurrences of the preceding element.
bar - a variable, usually obtained through calculations based on the
value(s) of field(s). Variables are introduced into the
specification solely as a means to clarify the description.
address-length - a variable whose value is the length of an address
in octets, it is 4 if using IPv4, 16 if using IPv6.

3. Applicability Statement
This specification describes a generic multi-message packet format,
for carrying MANET routing protocol signals. The specification has
been developed from that used by OLSR (The Optimized Link State
Routing Protocol) [4].
The specification is designed specifically with IP (IPv4/IPv6) in
mind. All addresses within a control message are assumed to be of
the same size, deduced from IP. In the case of mixed IPv6 and IPv4
addresses, IPv4 addresses are represented as IPv4-mapped IPv6
addresses as specified in [2].
The messages defined by this specification are designed to carry
routing protocol signals between MANET routers, and to support scope
limited diffusion, as well as point to point signaling in a multi-hop
network.
The packets defined by this specification are designed to carry a
number of messages between in a single transmission. The packets may
use any transport mechanism (unicast, multicast) and transport
protocol (TCP, UDP, ...) appropriate to the protocol using this
specification and may travel over a single logical hop which might
consist of one or more IP hops. When the diffusion mechanism enabled
by this specification is employed, UDP may be most appropriate.
This specification is particularly appropriate for extensible
protocols. It offers external extensibility in the form of new
message types. It offers internal extensibility in the form of TLVs,
which may be added to existing message types.
A protocol using the multi-message packet format defined by this
specification may constrain the syntax (for example requiring a full
message header) and features (for example specifying the suggested
diffusion mechanism) that the protocol will employ.

Internet-Draft MANET packet format June 2007
4. Protocol Overview and Functioning
This specification does not describe a protocol. It describes a
packet format, which may be used by any mobile ad hoc network routing
or other protocol.
Clausen, et al. Expires December 17, 2007 [Page 7]
Internet-Draft MANET packet format June 2007
5. Signaling Framework
This section provides syntactical specification of a packet,
represented by the element <packet> and the elements from which it is
composed. The specification is given in the form of regular
expressions. Illustrations of specified elements are given in
Appendix A.
The length of a <packet> is obtained as the size of the payload of
the transport protocol employed.
5.1. Packets
<packet> is defined by:
<packet> = {<packet-header><pad-octet>*}?
{<message><pad-octet>*}*
where <message> is defined in Section 5.2, and <pad-octet> is defined
in Section 5.4. Successful parsing is terminated when all octets are
used.
<packet-header> is defined by:
<packet-header> = <zero>
<packet-semantics>
<packet-seq-number>?
<tlv-block>?
where:
<zero> is an 8 bit field with all bits cleared ('0'). This field
serves to identify that the packet starts with a packet header.
<packet-semantics> is an 8 bit field, specifying the composition of
the packet header:
bit 0 (pnoseqnum): if cleared ('0'), then the packet header
contains a <packet-seq-number>. If set ('1'), then the packet
header does not include a <packet-seq-number>.
bit 1 (ptlv): if cleared ('0'), then the packet header does not
include a TLV block. If set ('1'), then the packet header
includes a TLV block.
Clausen, et al. Expires December 17, 2007 [Page 8]
Internet-Draft MANET packet format June 2007
bits 2-7: are RESERVED, and MUST each be cleared ('0') to be in
conformance with this version of the specification.
<packet-seq-number> is omitted if the pnoseqnum bit is set ('1'),
otherwise is a 16 bit field, specifying a packet sequence number.
<tlv-block> is omitted if the ptlv bit is cleared ('0'), and is
otherwise defined in Section 5.3.
Note that since the message type zero is reserved (see Section 7),
the presence or absence of a packet header can be determined by
inspecting the first octet of the packet.
5.2. Messages
Information is carried through messages. Messages contain:
o A message header.
o A message TLV block that contains zero or more TLVs, associated
with the whole message.
o Zero or more address blocks, each containing one or more
addresses.
o A TLV block, containing zero or more TLVs, following each address
block.
<message> is defined by:
<message> = <msg-header>
<tlv-block>
{<addr-block><tlv-block>}*
<msg-header> = <msg-type>
<msg-semantics>
<msg-size>
<msg-header-info>
<msg-header-info> = <originator-address>?
<hop-limit>?
<hop-count>?
<msg-seq-number>?
where:
Clausen, et al. Expires December 17, 2007 [Page 9]
Internet-Draft MANET packet format June 2007
<tlv-block> is defined in Section 5.3.
<addr-block> is defined in Section 5.2.1.
<msg-type> is an 8 bit field, specifying the type of message. A
type with all bits cleared ('0') MUST NOT be used.
<msg-semantics> is an 8 bit field, specifying the interpretation of
the remainder of the message header:
bit 0 (noorig): If cleared ('0'), then <originator-address> is
included in the <msg-header-info>. If set ('1'), then
<originator-address> is not included in the <msg-header-info>.
bit 1 (nohoplimit): If cleared ('0'), then <hop-limit> is
included in the <msg-header-info>. If set ('1'), then <hop-
limit> is not included in the <msg-header-info>.
bit 2 (nohopcount): If cleared ('0'), then <hop-count> is
included in the <msg-header-info>. If set ('1'), then <hop-
count> is not included in the <msg-header-info>
bit 3 (noseqnum): If cleared ('0'), then <msg-seq-number> is
included in the <msg-header-info>. If set ('1'), then <msg-
seq-number> is not included in the <msg-header-info>.
bit 4 (typedep): If cleared ('0'), then the message sequence
number in the message is type-independent. If set ('1'), then
the message sequence number contained in the message is type
dependent (the message originator maintains a sequence number
specific to <msg-type>). This bit MUST be cleared ('0') if the
noorig bit is set ('1').
bits 5-7: are RESERVED and MUST each be cleared ('0') to be in
conformance with this version of the specification.
If bit 0 (noorig) and bit 3 (noseqnum) are both cleared, then the
message header provides for duplicate suppression.
If bit 1 (nohoplimit) and bit 2 (nohopcount) are both cleared,
then the message header provides for scope-delimited forwarding.
<msg-size> is a 16 bit field, specifying the size of the <message>,
counted in octets.
Clausen, et al. Expires December 17, 2007 [Page 10]
Internet-Draft MANET packet format June 2007
<originator-address> is an identifier of length equal to address-
length, which serves to uniquely identify the node that originated
the message.
<hop-limit> is an 8 bit field, which contains the maximum number of
logical hops a message should be further transmitted.
<hop-count> is an 8 bit field, which contains the number of logical
hops a message has traveled.
<msg-seq-number> is a 16 bit field, which contains a unique number,
generated by the originator node. The <originator-address>, <msg-
seq-number>, and, if the typedep bit in the <msg-semantics> field
is set, the <msg-type> of a message serves to uniquely identify
the message in the network.
5.2.1. Address Blocks
An address is specified as a sequence of address-length octets of the
form head:mid:tail. An address block is an ordered set of addresses
sharing the same head and tail, and having individual mids. Network
addresses may be represented using the PREFIX_LENGTH TLV defined in
Section 6.
<address block> is defined by:
<address-block> = <num-addr>
<addr-semantics>
<head-length>?
<head>?
<tail-length>?
<tail>?
<mid>*
where:
<num-addr> is an 8 bit field containing the number of addresses
represented in the address block, which MUST NOT be zero.
<addr-semantics> is an 8 bit field specifying the interpretation of
the remainder of the address block:
bit 0 (nohead): if cleared ('0'), then <head-length> is included
in <address-block>, and <head> may be included in <address-
block>. If set ('1'), then <head-length> and <head> are not
included in <address-block>.
Clausen, et al. Expires December 17, 2007 [Page 11]
Internet-Draft MANET packet format June 2007
bit 1 (notail) and bit 2 (zerotail): MUST NOT both be set ('1').
Otherwise, they are interpreted according to Table 1.
+--------+----------+---------------+-----------------+
| notail | zerotail | <tail-length> | <tail> |
+--------+----------+---------------+-----------------+
| 0 | 0 | included | may be included |
| | | | |
| 0 | 1 | included | not included |
| | | | |
| 1 | 0 | not included | not included |
+--------+----------+---------------+-----------------+
Table 1
bits 3-7: are RESERVED and MUST each be cleared ('0') to be in
accordance with this version of the specification.
<head-length> if present is an 8 bit field, which contains the total
length (in octets) of the head of all of the addresses.
head-length is a variable, defined to equal <head-length> if
present, or 0 otherwise.
<head> is omitted if head-length == 0, otherwise it is a field of
the head-length leftmost octets of all the addresses.
<tail-length> if present is an 8 bit field, which contains the total
length (in octets) of the tail of all of the addresses.
tail-length is a variable, defined to equal <tail-length> if
present, or 0 otherwise.
<tail> is omitted if tail-length == 0 or if the zerotail bit is set
('1'), otherwise it is a field of the tail-length rightmost octets
of all the addresses. If the zerotail bit is set ('1') then the
tail-length rightmost octets of all the addresses are all 0.
mid-length is a variable, which MUST be non-negative, defined by:
* mid-length = address-length - head-length - tail-length
<mid> is omitted if mid-length == 0, otherwise each <mid> is a field
of length mid-length octets, representing the mid of the
corresponding address in the address block.
Clausen, et al. Expires December 17, 2007 [Page 12]
Internet-Draft MANET packet format June 2007
5.3. TLVs and TLV Blocks
A TLV block is defined by:
<tlv-block> = <tlv-length>
<tlv>*
where:
<tlv-length> is a 16 bit field, which contains the total length (in
octets) of all of the immediately following <tlv> elements.
<tlv> is defined in Section 5.3.1.
5.3.1. TLVs
There are three kinds of TLV, each represented by an element <tlv>:
o A packet TLV, included in a packet header.
o A message TLV, included in a message before all address blocks.
o An address block TLV, included in a TLV block following an address
block. An address block TLV applies to:
* all addresses in the address block; OR
* any continuous sequence of addresses in the address block; OR
* a single address in the address block.
<tlv> is defined by:
<tlv> = <tlv-type>
<tlv-semantics>
<index-start>?
<index-stop>?
<length>?
<value>?
where:
<tlv-type> is an 8 bit field, specifying the type of the TLV,
specific to the TLV kind (i.e. packet, message, or address block
TLV).
Clausen, et al. Expires December 17, 2007 [Page 13]
Internet-Draft MANET packet format June 2007
<tlv-semantics> is an 8 bit field specifying the interpretation of
the remainder of the TLV:
bit 0 (extended) and bit 1 (novalue): MUST NOT both be set ('1').
Otherwise, they are interpreted according to Table 2.
+----------+---------+--------------+--------------+
| extended | novalue | <length> | <value> |
+----------+---------+--------------+--------------+
| 0 | 0 | 8 bits | included |
| | | | |
| 0 | 1 | not included | not included |
| | | | |
| 1 | 0 | 16 bits | included |
+----------+---------+--------------+--------------+
Table 2
bit 2 (noindex) and bit 3 (singleindex): MUST NOT both be set
('1'). The former MUST be set ('1') and the latter MUST be
cleared ('0') for packet or message TLVs. They are interpreted
according to Table 3.
+---------+-------------+---------------+--------------+
| noindex | singleindex | <index-start> | <index-stop> |
+---------+-------------+---------------+--------------+
| 0 | 0 | included | included |
| | | | |
| 0 | 1 | included | not included |
| | | | |
| 1 | 0 | not included | not included |
+---------+-------------+---------------+--------------+
Table 3
bit 4 (multivalue): this bit serves to specify how the <value>
field is interpreted, as specified below. This bit MUST be
cleared ('0') for packet or message TLVs, if the singleindex
bit is set ('1'), or if the novalue bit is set ('1').
bits 5-7: are RESERVED and MUST each be cleared ('0') to be in
accordance with this version of the specification.
<index-start> and <index-stop> when present are each an 8 bit field,
interpreted as follows:
Clausen, et al. Expires December 17, 2007 [Page 14]
Internet-Draft MANET packet format June 2007
index-start and index-stop are variables, defined according to
Table 4. The variable end-index is defined as follows:
+ For message and packet TLVs:
- end-index = 0
+ For address block TLVs:
- end-index = <num-addr> - 1
+---------+-------------+---------------+---------------+
| noindex | singleindex | index-start = | index-stop = |
+---------+-------------+---------------+---------------+
| 0 | 0 | <index-start> | <index-stop> |
| | | | |
| 0 | 1 | <index-start> | <index-start> |
| | | | |
| 1 | 0 | 0 | end-index |
+---------+-------------+---------------+---------------+
Table 4
For an address block TLV, the TLV applies to the addresses from
position index-start to position index-stop (inclusive) in the
address block, where the first address has position zero.
number-values is a variable, defined by:
+ number-values = index-stop - index-start + 1
<length> is omitted or is a 8 or 16 bit field according to Table 2.
If present it MUST NOT be zero. If the multivalue bit is set
('1') then <length> MUST be an integral multiple of number-values,
and the variable single-length is defined by:
* single-length = <length> / number-values
If the multivalue bit is cleared ('0'), then the variable single-
length is defined by:
* single-length = <length>
<value> if present (see Table 2) is a field of length <length>
octets. In an address block TLV, <value> is associated with the
addresses from index-start to index-stop, inclusive. If the
multivalue bit is cleared ('0') then the whole of this field is
associated with each of the indicated addresses. If the
Clausen, et al. Expires December 17, 2007 [Page 15]
Internet-Draft MANET packet format June 2007
multivalue bit is set ('1') then this field is divided equally
into number-values fields, each of length single-length octets and
these are associated, in order, with the indicated addresses.
5.3.2. Constraints
TLVs in the same TLV block MUST be sorted in ascending TLV type
order.
Two or more TLVs of the same type associated with the same address
block MUST NOT both cover any address.
TLVs of the same type associated with the same address block MUST be
sorted in ascending index-start order.
5.4. Padding
Packet headers and messages MAY be padded to ensure 32 bit alignment
of each message contained within the packet and of the overall packet
length.
All elements are an integer multiple of octets, hence padding can be
accomplished by inserting an integer number of <pad-octet> elements
after the element that is to be 32 bit aligned.
The number of <pad-octet> elements required to achieve this 32 bit
alignment is the smallest number (0 to 3) that, when added to the
size of the preceding elements, produces an integer multiple of 4.
<pad-octet> is an 8 bit field with all bits cleared ('0').
There is no need to indicate if padding is included, since a <pad-
octet> will always precede either a message or the end of the packet.
In the former case, the start of a message is indicated by the next
non-zero octet parsed.
The padding after a message may be freely changed when a message is
forwarded without affecting the message.

6. TLV specification
This document specifies one address block TLV, which is included to
allow a standardized way of representing network addresses.
6.1. Address Block TLV Specification
+----------------------+------+--------+----------------------------+
| Name | Type | Length | Value |
+----------------------+------+--------+----------------------------+
| PREFIX_LENGTH | 0 | 8 bits | Indicates that the address |
| | | | is a network address, |
| | | | rather than a host |
| | | | address. The value is the |
| | | | length of the |
| | | | prefix/netmask. |
+----------------------+------+--------+----------------------------+
Table 5
An address in an address block without an associated PREFIX_LENGTH
TLV may be considered to have a prefix length equal to the address
length in bits (i.e. address-length times 8).

Internet-Draft MANET packet format June 2007
7. IANA Considerations
A new registry for message types must be created with initial
assignments as specified in Table 6. Future values in the range
5-127 can be allocated using standards action [3]. Additionally,
values in the range 128-255 are reserved for private/local use.
+-------+----------------------------------------+
| Value | Description |
+-------+----------------------------------------+
| 0 | MUST NOT be allocated. |
| | |
| 1-4 | RESERVED |
+-------+----------------------------------------+
Table 6
Message type 0 MUST NOT be allocated because a zero-octet signifies a
packet header and zero-octets are used for padding. Message types 1
to 4 are reserved because they are used by OLSR [4], which uses a
compatible packet/message header format.
A new registry for packet TLV types must be created, with no initial
assignments. Future values in the range 0-127 can be allocated using
standards action [3]. Additionally, values in the range 128-255 are
reserved for private/local use.
A new registry for message TLV types must be created with no initial
assignments. Future values in the range 0-127 can be allocated using
standards action [3]. Additionally, values in the range 128-255 are
reserved for private/local use.
A new registry for address block TLV types must be created with
initial assignments as specified in Table 7. Future values in the
range 1-127 can be allocated using standards action [3].
Additionally, values in the range 128-255 are reserved for private/
local use.
+--------------------+-------+--------------------------------------+
| Mnemonic | Value | Description |
+--------------------+-------+--------------------------------------+
| PREFIX_LENGTH | 0 | Indicates that associated addresses |
| | | are network addresses, with given |
| | | prefix length. |

8. Security Considerations
Messages are designed to be carriers of protocol information and MAY,
at each hop, be forwarded and/or processed according to the
information in the message header by the protocol using this
specification.
For forwarded messages where the message is unchanged by forwarding
nodes, then end-to-end security MAY be implemented, between nodes
with an existing security association, by including a suitable
message TLV containing a cryptographic signature in the message.
Since <hop-count> and <hop-limit> are the only fields that may be
modified when such a message is forwarded in this manner, this
signature can be calculated based on the entire message, including
the message header, with the <hop-count> and <hop-limit> fields set
to zero ('0') if present.
Packets are designed to carry a number of messages between
neighboring nodes in a single transmission and over a single logical
hop. Hop-by-hop packet level security MAY be implemented, between
nodes with an existing security association, by including a suitable
packet TLV containing a cryptographic signature to the packet. Since
packets are received as transmitted, this signature can be calculated
based on the entire packet, or on parts thereof as appropriate.

Appendix B. Complete Example
An example packet, using IPv4 addresses (length four octets) is
shown. This packet has a header, indicated by the initial octet 0.
The packet header has semantics octet 0, and hence has a packet
sequence number, but no packet TLV block.
The packet contains a single message. This message has semantics
octet 0, and hence has a complete message header, including
originator address, hop limit, hop count and message sequence number
(which is type independent). The message has a message TLV block
with content length 9 octets, containing a single TLV. This TLV has
the noindex bit of its semantics octet 4 set, and has value length 6
octets. The message then has two address blocks each with a
following TLV block.
The first address block contains 3 addresses. It has the notail bit
of its semantics octet 2 set, and has head length 2 octets, hence mid
length two octets. It is followed by a TLV block, with content
length 9 octets, containing two TLVs. The first of these TLVs has
the noindex bit of its semantics octet 4 set, and has a single value
of length 2 octets, which applies to all of the addresses in the
address block. The second of these TLVs has the novalue bit of its
semantics octet 2 set, and hence has no length or value fields. It
does have index fields, which indicate those addresses this TLV
applies to.
The second address block contains 2 addresses. It has the nohead and
zerotail bits of its semantics octet 5 set, and has tail length 2
octets, hence mid length two octets. The two tail octets of each
address are zero. It is followed by a TLV block with content length
5 octets. This TLV block contains a single TLV of type PREFIX_LENGTH
that has the multivalue and noindex bits of its semantics octet 20
set, and a value field length of 2 octets, indicating two values each
of one octet length. There is one final padding octet 0 that is not
included in the message length of 59 octets.
