Abstract

Reliability, security, scalability and QoS(Quality-of-Service) have become key issues as we envisionthe future Internet. This paper presents the "CognitivePacket Network (CPN)" architecture in which intelligentpeer-to-peer routing is carried out with the help of "smartpackets" based on best-effort QoS goals. Since packetizedvoice has stringent QoS requirements, we then discuss thechoice of a "goal" and "reward" function for this applicationand present experiments we have conducted for "voiceover CPN". Its performance is detailed via several measurements,and the resulting QoS is compared with that of theIP routing protocol under identical conditions showing thegain resulting from the use of CPN.
