This is the greatest Advertised Neighbor Sequence Number (ANSN) in any TC message received that originated from the router with originator address olsrv2TibAdRemoteRouterSetIpAddr. Sequence numbers are used in the OLSRv2 protocol for the purpose of discarding 'old' information, i.e., messages received out of order. However, with a limited number of bits for representing sequence numbers, wraparound (that the sequence number is incremented from the maximum possible value to zero) will occur. To prevent this from interfering with the operation of this protocol, OLSRv2 implementations observe the following when determining the ordering of sequence numbers. In OLSRv2, MAXVALUE designates one more than the largest possible value for a sequence number. For a 16-bit sequence number, MAXVALUE is 65536. The sequence number S1 is said to be 'greater than' the sequence number S2 if: o S1 > S2 AND S1 - S2 < MAXVALUE/2 OR o S2 > S1 AND S2 - S1 > MAXVALUE/2 When sequence numbers S1 and S2 differ by MAXVALUE/2, their ordering cannot be determined. In this case, which should not occur, either ordering may be assumed. Thus, when comparing two messages, it is possible - even in the presence of wraparound - to determine which message contains the most recent information.
