“…Furthermore, RoHCv1 and RoHCv2 performance was evaluated for RTP in [15] and was shown that both versions perform equally well for Voice-over-IP transmissions, albeit RoHCv2's gain is slightly better by 5-10 %. [15] also shows, that RoHCv2 uses more complexity on the compressor side, but is much faster during decompression than RoHCv1.…”

Modern cellular networks utilising the Long-Term Evolution (LTE) set of standards face an ever-increasing demand for mobile data from connected devices. Header compression is employed to minimise the overhead for IP-based cellular network traffic. In this paper, we evaluate the three header compression implementations used by such networks with respect to their potential throughput increase and complexity for different mobile service scenarios. We compare RTP, UDP and TCP profile compressions regarding their compression gain and complexity. Specifically, we consider header compression as defined by (i) IP Header Compression (RFC 2507), (ii) Robust Header Compression version 1 (RFC 3095), and (iii) the recently updated Robust Header Compression version 2 (RFC 5225) with TCP/IP profile (RFC 6846). This paper presents the performance evaluation of these header compression schemes for UDP, RTP and TCP, for both IPv4 and IPv6 streams in error-free and error-prone scenarios. A comparison between the Robust Header Compression methods and IP Header Compression is also provided. Our results show that all implementations have great potential for saving bandwidth in IP-based wireless networks, even under varying channel conditions. We also present for the first time an analysis of certain RTP header fields which, depending on the transmission characteristics, could have high impact on the overall compression gain.

“…If there is an update or error has occurred, the compressor shifts back to upper compression levels and returns back to the SO compression state only after re-transmitting the updated information and establishing again the change pattern in the de-compressor. Context is used to store the information with regards to the header fields and size of the compressed header depends on the compression level and the header information required by the decompressor [114].

“…The ROHC version 2 (ROHCv2) [121], extends the previously mentioned ROHC by increasing in overall simplicity and robustness, with equivalent or enhanced performance. ROHCv2 is a complete new design for performance enhancement [114]. It has a robustness method used by a compressor to boost the prospect of decompression success when packets can be lost and/or reordered on the ROHC channel [117].…”

Due to the rapid evolution of Internet as well as services over the Internet, including high bandwidth consuming applications like audio and video streaming, it has become need of the day to enhance the Internet infrastructure for bandwidth efficiency. Developed by the Internet Engineering Task Force, MPLS allows networks to offer several services on the single network architecture with improved forwarding speed of routers by solving problem of longest prefix match in IP networks. In addition to this, it offers Traffic Engineering, Virtual Private Networks and Quality of Service guarantees. MPLS in combination with Internet Protocol version 6 (IPv6) has been seen as a technology for next generation Internet, which can revolutionize the Internet with speed, services and functionality. IPv6 provides huge number of addresses and guaranteed support for the ever increasing demand. However, there is a disadvantage of bigger packet header size compared to the payload size which leads to excessive overhead in case of real-time multimedia applications. Bandwidth can be conserved by reducing the amount of redundant IP header transmitted with every packet for the same packet stream through header compression/suppression techniques. The objective of this paper is to survey of various header compression technologies which can be implemented over MPLS with IPv6 as the addressing protocol, which can be used as a bandwidth conserving technology. The current efforts in the area, both standardised as well as ongoing research has been discussed in detail and also the problems that are yet to be addressed are examined.

Communication over Internet Protocol (IP) networks, has become crucial component of day everyday activities. They are utilized over the Internet to support a wide range of services. The flexibility of this kind of transmission relies on the IP User Datagram Protocol (UDP), IP/UDP/Real-time Transport Protocol (RTP) and IP/Transmission Control Protocol (TCP). Unfortunately, the weight of encapsulated protocol headers affects the transmission efficiency. This research aims at improving a technique that reduce the packets header size by compression. Performance analysis of the enhanced efficient techniques in both unidirectional and bidirectional optimistic modes applied to real-time video streaming traffic for UDP/IP and HTTP/TCP flows over free error channel has been conducted. The finding shows that the header compression ratio in each case is good and better than the previous studies. The technique achieved a reduction up to 90% for RTP/UDP/IP, 89% for UDP /IP and 77.5 to 86.5 % for TCP/IP profile. This research contribution is restricted to compression gain and saving for 0 × 0000, 0 × 0001, 0 × 0002 and 0 × 0006 profiles in the unidirectional and bidirectional optimistic modes. INDEX TERMS Datagram protocol, real-time transport protocol, transmission control protocol, protocol headers.
