Smart box architecture: a hybrid solution for IP QoS provisioning

摘要

This work proposes a hybrid solution, called the smart box architecture (SboX), that provides quality of service (QoS) in internet protocol (IP)-based networks. SboX architecture consists of SboX servers, which are located at the network boundary, and SboX routers, which are add-on label switching routers (LSR), which are located at interior network nodes. This approach combines the advantages of three existing technologies: integrated services (Intserv), differentiated services (Diffserv), and multi-protocol label switching (MPLS). SboX aggregates traffic in three levels: commodity-flows, macro-flows and micro-flows. Commodity-flows aggregate flow between every pair of edge points.
