LIC-BASED FAST FORWARDING TOWARDS SCALABILITY, SIMPLICITY, FLEXIBILITY AND SECURITY

To reduce the cost of routing devices and to improve network performances for both wired and wireless packet networks, thIs paper proposes the LI~k Interface Code (LIC) based forwarding, which can achieve fast flexible switching with scalabilIty, sImplIcity, secunty and enhancement of the network QoS ability. LIC-based forwarding uses the LIC to route and forward the data packet m each router. It executes like the explicit route by establishing the connection-oriented LIC path m advance and It can run on existing routing protocols. We design two types of codes for the LIC-based forwarding, the One-way connection-based LIC (OLIC) and the Two-way connection-based Lie (TLIC). The QLIC just contains route mformatlOn from a send to its receiver and the TLIC contains both the route information from the send to its receiver and the route information from the receiver to its sender. Compared with OLIC, TLIC is more suitable for mteractIve real-time applications. Experiment result shows that LIC-based forwarding achieves lower end-to-end delay than MPLS does and It can provide flexIble fast forwarding.
