Increasing Router Efficiency by Parallel Buffering and Packet Clustering Techniques
... Abstract— To increase the efficiency of the router at the high bandwidth usage paths in the network by adopting two techniques that are packet parallel buffering and packet clustering methods. In parallel buffering method we use high speed RAM memories to increase the packet buffer memory and these ...
