Abstract
The Internet consists of a number of interconnected networks supporting communication among host computers using the Internet protocols. One of the most important constituents of the Internet is an IP router or a gateway. A router is connected to two or more networks, appearing to each of these networks as a connected host. If the processing capability of a router is further enhanced to support computation on parts of data contained in a datagram, some of the end host computation can be delegated to the routers that the data passes through. The instructions about how to do the processing itself could be provided by the end. This thesis defines a reliable transport layer protocol, Intermediate Processing Protocol (IPP), which is a set of rules and guidelines for processing within the Internet. The protocol design addresses provision for connection set up handshake, acknowledgement of data received, router reservation policy, intermediate processing, buffering and retransmission of data, flow control, congestion control, ordered delivery of data and security issues.
