#include <aspath.hh>
This file contains the classes to manipulate AS segments/lists/paths
An AS_PATH is made of a list of segments, each segment being an AS_SET or an AS_SEQUENCE. Logically, you can think an AS_SEQUENCE as a list of AsNum, and an AS_SET as an unordered set of AsNum; the path would then be made of alternate AS_SET and AS_SEQUENCEs. However, the max number of elements in an AS_SEQUENCE is 255, so you might need to split a sequence into multiple ones.
The external representation of AS_SET or AS_SEQUENCE is: 1 byte: segment type 1 byte: number of element in the segment n entries: the ASnumbers in the segment, 2 or 4 bytes each
In terms of internal representation, it might be more efficient useful to store segments as either an AS_SET, or a sequence of size 1, and then do the necessary grouping on output.
The current implementation allows both forms.
Note that the external representation (provided by encode()) returns a malloc'ed chunk of memory which must be freed by the caller.
RFC 3065 (Autonomous System Confederations for BGP) introduced two additional segment types:
AS_CONFED_SEQUENCE: ordered set of Member AS Numbers in the local confederation that the UPDATE message has traversed
AS_CONFED_SET: unordered set of Member AS Numbers in the local confederation that the UPDATE message has traversed

#include <path_attribute.hh>
PathAttribute
components of the path attribute. They have variable sizes The actual layout on the wire is the following: [ flags ] 1 byte [ type ] 1 byte [ len ][....] 1 or 2 bytes [ data ] len bytes
PathAttribute is the base class for a set of derived class which represent the various attributes. A PathAttribute object of a given type can be created explicitly, using one of the constructors, and then adding components to it; or it can be created by calling the create() method on a block of data received from the wire.
In addition to the parsed components (next hops, AS numbers and paths, and various other attributes), the objects always contain the wire representation of the object, a pointer to which is accessible with the data() method, and whose size is size(). Whenever the object is altered, the wire representation needs to be recomputed.
