METHOD AND SYSTEM FOR HOST ROUTE REACHABILITY IN PACKET TRANSPORT NETWORK ACCESS RING Russian patent published in 2014 - IPC H04W40/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to a packet transport network. The method comprises steps of: setting a function of communication between an address resolution protocol (ARP) module and a static route module in a network-layer interface of a convergence node; automatically updating the static route entry obtained from other nodes, corresponding to a host address of an access node by the convergence node according to an ARP entry about each access node obtained from other nodes; and transmitting, by the convergence node, information about the current static route entry obtained from other nodes, corresponding to the host address of the access node to a core node and other networks according to a dynamic route protocol. The automatic updating comprises: detecting, by the ARP module of the convergence node, whether a new ARP entry is added; whether a host address in the newly added ARP entry and a network-layer interface address of the convergence node are in a same network segment; automatically adding the static route entry corresponding to the host address of the access node in the convergence node according to the newly added ARP entry.

EFFECT: high reliability of connecting communication nodes within a PTN access ring.
