PETRA: Performance Enhancing Transport Architecture for Satellite Communications

Abstract

Abstract-This paper presents a performance enhancing transport architecture for the satellite environment. This solution improves the network transport performance by overcoming the limits imposed by a transmission control protocol/Internet protocol (TCP/IP)-based stack suite, while maintaining the interfaces offered by it. This is an important issue since TCP/IP is widely used and most of the applications are based on it. The work starts from the state-of-the-art about the transport layer over satellite by distinguing two alternative frameworks: the black box (BB) and the complete knowledge (CK) approaches. In the former, the network is considered as a "black box" and only modifications in the terminal tools are permitted. In the latter, the complete control of any network element is allowed so as a performance optimization procedure is possible. The proposed architecture [called Performance Enhancing Transport Architecture (PETRA)] is designed in all details using the second approach. PETRA uses network elements, called relay entities, to isolate the satellite portions in case of heterogeneous networks, while a transport layer protocol stack is used to optimize the transport of information over satellite links. A special satellite transport protocol, that is part of the transport layer protocol stack, is used over such links to perform error recovery. Simulation results show that the proposed framework significantly enhances throughput performance.

A New Transmission Control Protocol for Satellite Networks

“…3) Agent solution program adopt agent manner (TCP-Spoofing, TCP-Splitting) [13], [14], [15] which refer to TCP-Spoofing, Snoop-TCP, TCP-Sp litt ing and I-TCP. The core idea of agent manner is that it sends fake response informat ion at satellite network gate-way so that the users can not detect the long propagation delay in satellite link.…”

Challenges, opportunities, and solutions for converged satellite and terrestrial networks

“…This is similar in spirit to the concept of the Explicit Control Protocol (XCP). Using such rate-based congestion control mechanism, and similar in spirit to the connection splitting in [3], the full end-to-end path will be decoupled into In light of the rapid globalization of the Internet and the resultant universality of IP, the data traffic load to be generated from the interworked satellite/terrestrial networks is expected to be all-IP as well.…”

“…Other approaches to transport protocol design are found in [1], [2], [4], [5], [15], [17], [22], [23], [25], [28], [29], [33], [34], [38], [40], [41], and [42] where the transport protocol stack in the sender and receiver are only modified. Transport protocols with network-assisted operation are given in [8], [9], [11], [13], [14], [18], [19], [24] and [27].…”
