Abstract:
In a network having at least one peer group including a plurality of nodes, a method for managing calls between a set of nodes, the method comprising:establishing a reroutable call path connecting a source node to a destination node, the reroutable call path traversing the set of nodes;detecting an event associated with the reroutable call path;generating a reincarnate request upon an occurrence of the event by inserting a rendezvous node address in a called party identifier IE associated with the reincarnate request, wherein the reincarnate request includes a rerouting type;determining a new call path connecting a new set of nodes in a peer group, wherein the peer group includes at least one level, wherein the level includes a set of border nodes defining a peer group segment path;calculating a route to a rendezvous node via the peer group segment path, wherein the rendezvous node is a peer group exit border node;inserting, into the reincarnate request, an address stack specifying a nodal address and a level number for each node in the route to the rendezvous node, wherein the level number identifies the level on which the node resides;transmitting the reincarnate request from a rerouting node in the peer group to the rendezvous node via the route, wherein the rerouting node is a peer group entry border node; andestablishing the new call path connecting the new set of nodes, wherein the source node and the destination node remain connected.
