Internet-Draft RSerPool MIB June 2007
Abstract
RSerPool [2] is a framework to provide reliable server pooling. This
document defines a SMIv2 compliant Management Information Base (MIB)
providing access to managed objects in an RSerPool implementation.

2. The Reliable Server Pooling (RSerPool) Framework
For a detailed overview of the documents that describe the current
Reliable Server Pooling (RSerPool) framework, please refer to [1],
[2], [3], [4], [5] and [6]. A more informal introduction can be

3. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [12].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [9], STD 58, RFC 2579 [10] and STD 58, RFC 2580 [11].

As the figure shows, the MIB consists of three main branches:
"enrpServers", "poolElements" and "poolUsers". The first branch,
"enrpServers" is used to access managed objects in the set of ENRP
servers running on a given host. While it is assumed that it does
not make much sense to run multiple ENRP servers for the same
operation scope on one host, running multiple ENRP servers for
different operation scopes is very likely when the ENRP server
processes run on routers. Therefore, the MIB has to be able to
manage multiple ENRP servers on the same host. "poolElements" is used
to access managed objects in the set of Pool Elements that are
running on a given host and the third branch, "poolUsers" is used to
access managed objects in the set of Pool Users that are running on a
given host. In fact, the structure of the three branches is very
similar. Because the two branches are so similar, we describe only
the first branch in detail, and provide a summary description of the
second and third branch. We now proceed with a description of the
branches.
4.1. Access to managed objects on ENRP servers
The first branch describes managed objects at a set of ENRP servers.
Any given ENRP server of this set will, at a certain moment in time,
have registration information for a set of active pools. Each of
these pools in turn may have a list of pool elements that are
registered under that pool. To allow this information to be
Dreibholz, et al. Expires December 8, 2007 [Page 11]
Internet-Draft RSerPool MIB June 2007
retrieved via SNMP, the ERNP server branch of the RSerPool MIB uses
the table-in-table technique described in [18]. Specifically, the
ENRP servers branch creates four levels of nesting, as indicated in
the following diagram:
Nesting of ENRP Server Branch
Nesting Structure:
Level 1: enrpServerTable
Level 2: enrpServerPoolTable
Level 3: enrpServerPoolElementTable
Level 4: enrpServerASAPAddrListTable
enrpServerUserAddrListTable
Level 2: enrpServerENRPAddrListTable
Level 2: enrpServerPeerTable
Level 3: enrpServerPeerAddrListTable
The ENRP servers branch contains a table of the host's ENRP server
instances. Its purpose is to provide an index to an ENRP server for
all other tables. Each "conceptual row" in the enrpServerTable
contains the server's ENRP Identifier, the number of pools, PEs and
peers, the amount of ENRP endpoint addresses, the server's uptime and
a textual description of the server. The poolTable contains a single
entry for each pool that is currently registered. Each "conceptual
row" in the enrpServerPoolTable consists of a
enrpServerPoolTableEntry, with two elements: a enrpServerPoolIndex
and an OCTET STRING representation of the pool handle. The
enrpServerPoolIndex is simply an integer that is used to index into
the enrpServerPoolTable and the enrpServerPoolElementTable. The
value of this integer is between zero and (poolCount - 1). Note that
the value of enrpServerPoolIndex is defined as "not-accessible" in
the MAX-ACCESS clause; this is a standard technique used when
defining a table-in-table data structure. The third element on the
ENRP servers branch is the enrpServerPoolElementTable. Because the
enrpServerPoolElementTable is the "inner" table of the table-in-table
structure, its index consists of a pair, as indicated in the clause
"INDEX { enrpServerIndex, enrpServerPoolIndex,
enrpServerPoolElementIndex }". The fourth element of the ENRP
servers branch takes the nesting to one additional level, listing the
various addresses associated with a particular enrpServerPoolElement
in form of ASAP endpoint addresses and user transport addresses, and
thus are indexed by the 4-tuples "INDEX { enrpServerIndex,
Dreibholz, et al. Expires December 8, 2007 [Page 12]
Internet-Draft RSerPool MIB June 2007
enrpServerPoolIndex, enrpServerPoolElementIndex,
enrpServerASAPAddrListTableIndex }" and "INDEX { enrpServerIndex,
enrpServerPoolIndex, enrpServerPoolElementIndex,
enrpServerUserAddrListTableIndex }". The ENRP endpoint addresses of
an ENRP server are bound to its instance in the
enrpServerENRPAddrListTable by "INDEX { enrpServerIndex,
enrpServerENRPAddrListTableIndex }". Finally, an ENRP server has a
peer table of its known peers. They are bound to a server instance
by the enrpServerPeerTable; analogously, the addresses of a peer are
bound to a peerTable's entry in the peerAddrListTable.
4.2. Access to managed objects on Pool Elements
The construction of the Pool Elements branch is very similar to the
pool elements table of the ENRP servers branch. But instead of
grouping the pool elements into pools (which does not make sense
here), the pool elements table is the top of the hierarchy and each
pool element entry specifies its operation scope and pool handle.
That is, the nesting structure is as follows:
Level 1: poolElementTable
Level 2: poolElementASAPAddrListTable
poolElementUserAddrListTable
The description of the contained structures is the same as for the
ENRP servers branch.
TODO: There should be the server table (ENRP servers learned by their
announces) plus the multicast address the PE expects the announces to
be sent to.
4.3. Access to managed objects on Pool Users
For the pool users branch, it is only necessary to list the pool
users, including their operation scope and pool handle.
TODO: There should be the server table (ENRP servers learned by their
announces) plus the multicast address the PE expects the announces to
be sent to.

6. Security Considerations
SNMPv1 by itself is not a secure environment. Even if the network
itself is secure (for example by using IPSec), there is no control as
to who on the secure network is allowed to access and GET/SET (read/
change/create/delete) the objects in this MIB.
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model RFC 2574 [7] and the View-based
Access Control Model RFC 2575 [8] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects only to those principals
(users) that have legitimate rights to indeed GET or SET (change/
create/delete) them.

7. IANA Considerations
IANA will need to assign an OID prefix for the RSerPool MIB.
