A Uniform Negotiation and Delivery Framework for TCP-Based Data Collaboration Applications

Abstract

In this paper we present a uniform negotiation and delivery framework for TCP-based data collaboration applications over IP network. With this framework rich innovative collaboration services can be developed conveniently and provide users with novel communication experience. The framework adopts the offer/answer model with extended Session Description Protocol as session description and negotiation mechanism and adopts MSRP as the media transport control protocol. In this paper, the requirement of the framework was revealed from a high-level design perspective and analyzed in detail by highlighting several prominent design choices such as uniform media description and negotiation, MSRP relay selection and TCP connection setup.
