urv.olsr.data
Class LinkCode

java.lang.Object
  urv.olsr.data.LinkCode

All Implemented Interfaces:

java.io.Serializable, org.jgroups.util.Streamable

public class LinkCode
extends java.lang.Object
implements java.io.Serializable, org.jgroups.util.Streamable

This field specifies information about the link between the interface of the sender and the following list of neighbor interfaces. It also specifies information about the status of the neighbor. Link codes, not known by a node, are silently discarded. The following four "Link Types" are REQUIRED by OLSR: - UNSPEC_LINK - indicating that no specific information about the links is given. - ASYM_LINK - indicating that the links are asymmetric (i.e., the neighbor interface is "heard"). - SYM_LINK - indicating that the links are symmetric with the interface. - LOST_LINK - indicating that the links have been lost. The following three "Neighbor Types" are REQUIRED by OLSR: - SYM_NEIGH - indicating that the neighbors have at least one symmetrical link with this node. - MPR_NEIGH - indicating that the neighbors have at least one symmetrical link AND have been selected as MPR by the sender. - NOT_NEIGH - indicating that the nodes are either no longer or have not yet become symmetric neighbors. Note that an implementation should be careful in confusing neither Link Type with Neighbor Type nor the constants (confusing SYM_NEIGH with SYM_LINK for instance). A link code advertising: Link Type == SYM_LINK AND Neighbor Type == NOT_NEIGH is invalid, and any links advertised as such MUST be silently discarded without any processing. Likewise a Neighbor Type field advertising a numerical value which is not one of the constants SYM_NEIGH, MPR_NEIGH, NOT_NEIGH, is invalid, and any links advertised as such MUST be silently discarded without any processing.
