摘要

可靠性、安全性、可扩展性和QoS(服务质量)已经成为我们展望未来互联网的关键问题。提出了“认知分组网络”(cognitive packet network, CPN)体系结构，在该体系结构中，基于最大努力的QoS目标，借助“智能分组”实现智能点对点路由。由于分组语音具有严格的QoS要求，因此我们讨论了该应用程序的“目标”和“奖励”功能的选择，并介绍了我们为“voice over CPN”进行的实验。通过几项测量详细介绍了其性能，并将所得到的QoS与IP路由协议在相同条件下的QoS进行了比较，显示了使用CPN所获得的增益。

Cognitive packet networks: QoS and performance

Reliability, security, scalability and QoS (quality-of-service) have become key issues as we envision the future Internet. The paper presents the "cognitive packet network" (CPN) architecture in which intelligent peer-to-peer routing is carried out with the help of "smart packets" based on best-effort QoS goals. Since packetized voice has stringent QoS requirements, we then discuss the choice of a "goal" and "reward" function for this application and present experiments we have conducted for "voice over CPN". Its performance is detailed via several measurements, and the resulting QoS is compared with that of the IP routing protocol under identical conditions showing the gain resulting from the use of CPN.
