Non-Blocking Destination-Based Routing Networks無阻擋英特綱的設計

Internet Protocol (IP) networks are originally designed to support a best-effort service. It does not guarantee reliable and timely delivered packets. As IP networks mature and are increasingly being used to support real-time applications, such as voice and video on the IP platform, the existing IP networks demand an improvement in providing a new level of quality of service (QoS) for such new applications to solve the traffic congestions on the Internet.

In this invention, it relates to the methods for building non-blocking destination-based routing network such as Internet. It is about the techniques for maintaining the hard QoS of the developing Internet. It applied a new computation algorithm and a load-distribution scheme for making a hop-by-hop routing network (such as Internet) non-blocking. They determine the paths of the hop-by-hop routing network and also the ingress and egress traffic constraints at the network edge. Therefore, the traffic entering and leaving the network does not exceed the constraints, none of the internal links will ever have traversing traffic more than its link capacity. The network is thus non-blocking internally. This greatly simplifies flow admission control and allows hard QoS to be supported inside the network.
Technology Benefits
1. Higher quality of service (QoS) of the developing Internet
2. Good router and network planning tools
Technology Application
- Routers, network planning tools
