The sequence of AS path segments. Each AS path segment is represented by a triple <type, length, value>. The type is a 1-octet field that has two possible values: 1 AS_SET: unordered set of ASes that a route in the UPDATE message has traversed 2 AS_SEQUENCE: ordered set of ASes that a route in the UPDATE message has traversed. The length is a 1-octet field containing the number of ASes in the value field. The value field contains one or more AS numbers. Each AS is represented in the octet string as a pair of octets according to the following algorithm: first-byte-of-pair = ASNumber / 256; second-byte-of-pair = ASNumber & 255; Known IssueVs: o BGP Confederations will result in a type of either 3 or 4. o An AS Path may be longer than 255 octets. This may result in this object containing a truncated AS Path.
