Abstract
AbstractVirtual circuit transmission mechanism as represented by MPLS has the characteristics of low forwarding overhead and short transmission delay. In contrast, the traditional packet forward mechanism is more flexible than the former in terms of dynamic packet forwarding routing. In this paper, we put forward an adaptation routing mechanism(ARM for short) of combination of packet forward with virtual circuits that is based on combination of the advantages of these transmission mechanisms. It can overcome the shortcomings of static and manual configurations in the MPLS mechanism. The experimental results show that it can not only improve the packet forwarding speed without replacing the router hardware, but also has advantages in reducing load pressure of partial nodes in the network topology and optimizing the partial or entire network transmission performance.Keywordstransmission mechanismtraditional packet forwardvirtual circuitMPLSload pressurenetwork topology
