Negotiation-based transport layer protocol for many-to-one transmission

Traditional approaches to utilize the multi-provider environment that has the servers with the same contents are classified into bandwidth aggregation on client-side and load reduction and balancing on server-side. However, previous approaches, client-side and server-side approaches, are hard to work together. In this paper, we present a transport layer protocol for many-to-one transmission that harmonies client and server reduction with a negotiation mechanism. It provides the way to inform clients of server contents and enhanced request distribution mechanism. Experimental results from our implementation on the Linux show that the protocol efficiently specializes each server for the certain contents while the out-of-order packets at clients are minimized.
