Abstract (en)

[origin: WO0141380A2] A routing protocol, called characteristic routing, which allows data to be transported multi-hop through an internetwork from a sender to a set of receiver nodes using a description of the receiver nodes in the form of multiple arbitrary identifying descriptive names (called characteristics). Host nodes can have multiple dynamic characteristics. Characteristic routing is optimized to make the multiple-name case operate in a fast manner. In particular, characteristic routing creates an efficient routing table index using bit vectors and compression techniques. Using characteristic routing, the sender can choose whether the receiver nodes need to exactly match the characteristic routing address or certain characteristics in the routing address, or whether the receiver nodes can be simply "similar" to the characteristic routing address, or whether the receiver nodes have desired ranges of characteristics.
