Performance Tradeoffs for Header Compression in MPLS Networks
نویسندگان
چکیده
In this paper, we propose the use of compression techniques for RTP/UDP/IP/MPLS headers in MPLS networks to enable header compression over several IP hops. We consider the transmission of low-bitrate real-time traffic and analytical results illustrate performance tradeoffs regarding network utilization by user data. Header compression reduces the gross rate of low-bitrate streams and increases the transmission capacity of the network for voice traffic by 150%. For circuit switched data services it is important to choose a suited packet size to maximize the performance. This explains why the reduced burstiness by header compression leads also to a more than intuitively expected performance gain on low-bandwidth access links.

RFC 4247 Requirements for Header Compression over MPLS
Voice over IP (VoIP) typically uses the encapsulation voice/RTP/UDP/IP. When MPLS labels are added, this becomes voice/RTP/UDP/IP/MPLS-labels. For an MPLS VPN, the packet header is typically 48 bytes, while the voice payload is often no more than 30 bytes, for example. Header compression can significantly reduce the overhead through various compression mechanisms, such as enhanced compressed RT...
متن کاملEnd-to-End QoS Improvement using IPv6 Header Reduction over MPLS
In 802.16 standards, PHS suppresses redundant parts of payload header in MAC service data unit. This paper proposes Label Switched Path-Payload Header Suppression (LSPPHS), in which an MPLS-enabled backbone route compresses packets over an MPLS LSP without compression or decompression cycles at each router. It has two main contributions for MPLS-IPv6 header compression. First, LSPPHS adds a new...
متن کاملAn All-MPLS Approach for UMTS 3G Core Networks
In this paper, we present an all-MPLS approach for UMTS 3G core networks. GTP-tunnel has been defined by 3GPP as the transport mechanism for UMTS. For each packet transmission, extra GTP, UDP, and IP headers (40-byte) are required. For short packets, such as VoIP payloads, transmission overhead is very high. Enhanced-GTP was proposed to eliminate the need for a GTP header. Since its operation m...

Today, the use of wireless and intelligent networks are widely used in many fields such as information technology and networking. There are several types of these networks that MPLS networks are one of these types. However, in MPLS networks there are issues and problems in the design and implementation discussion, for example security, throughput, losses, power consumption and so on. Basically,...
متن کاملPerformance evaluation and implementation of IP and robust header compression schemes for TCP and UDP traffic in static and dynamic wireless contexts
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 commonly employed to minimise the overhead for IP–based cellular network traffic. In this paper, we evaluate the three header compression implementations used by these networks with respect to their potential throughput in...
