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
