1. Introduction
This document defines binary formats for IPv4 and IPv6 traffic
selector sub-options, as defined in [RFC6089].
The binary traffic selector format defined here, allows for efficient
identification of flow(s) based on well-known fields in IPv4
[RFC0791], IPv6 [RFC2460], and transport layer headers like TCP
[RFC0793] and UDP [RFC0768].
2. Requirements Notation
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 [RFC2119].
3. Traffic Selector Sub-Options
[RFC6089] defines the format for the traffic selector sub-option.
The following values of the TS Format field are defined in this
specification for binary traffic selectors.
TS Format:
1 IPv4 binary traffic selector
2 IPv6 binary traffic selector
3.1. IPv4 Binary Traffic Selector
If the TS Format field of the traffic selector sub-option indicates
"IPv4 binary traffic selector", then the traffic selector is
formatted as shown below.

The alignment requirement for this sub-option is:
4n if A, B, C, D, E, or F is set
2n if G, H, I, or J is set
n if K, L, M, or N is set
