Abstract:
1. A method for selecting boundary nodes for communication between multiple local peer groups, the method comprising: receiving a first control packet that originated from a predetermined node, said predetermined node being a group header; determining if the first control packet is from a group header in a same local peer group; declaring a candidacy for a boundary node if the first control packet originated from a foreign local peer group, by transmitting a packet to the group header; receiving the transmitted packet from at least one candidate, at the group header; generating a list of candidates based upon the received transmitted packet, wherein said list of candidates is valid for a preset period of time, the time being a time-to-live value; selecting one candidate from the list of candidates as the boundary node; selecting a second boundary node, the second boundary node being in an opposite relative direction, upstream or downstream, for the group header as the boundary node; and transmitting a data packet containing an identifier for the selected boundary node; receiving the data packet containing an identifier for the selected boundary node; comparing the identifier for the selected boundary node within a receiving node's identifier; and changing a receiving node's status to a boundary node based upon the comparing; transmitting a second control packet periodically after changing status to a boundary node.
