Object

column OctetString
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 Issues:
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.
