Efficiency Issues in MPLS Transport for the UMTS Access Network
نویسندگان
چکیده
Multiprotocol Label Switching (MPLS) offers a simple and flexible transport solution for multiservice networks. Therefore, many UMTS operators are currently considering the use of a MPLS backbone. However, the efficient transport of short voice and data packets in the UMTS access network requires multiplexing and segmentation functions not provided by MPLS. This paper investigates the use of ATM Adaptation Layer 2 (AAL2) over MPLS to perform both functions. The efficiency of AAL2/MPLS is analyzed for different traffic types and compared with other transport options. The results indicate that significant capacity savings can be obtained with this solution.

MPLS/RSVP-TE-Based Future UMTS Radio Access Network
Currently we see a discussion on the transition from ATM-based transport to IP transport in the UMTS Terrestrial Radio Access Network (UTRAN). Issues that result from the transition to IP are QoS, esp. delay, jitter, loss, bandwidth guaranties and in sequence delivery of packets for voice traffic. The paper compares two solutions for future UTRANs, native IP multi-path transport and MPLS (Multi...
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...
متن کاملIntegration of Hierarchical Mobile IP into a MPLS-based UTRAN
The UMTS specification (Release 5), a third-generation mobile system, proposes an all-IP network architecture. In the near future, UMTS will offer a variety of services to users. Some of these services, e.g. real-time services, require a certain guaranteed quality of service. Multi Protocol Label Switching (MPLS) is a technology providing means to control data flows in IP networks. MPLS has bee...

متن کاملMPLS Based Mobility Framework in 4G Architectures
In this paper, an integration framework for 4Gnetwork architecture between UMTS-GPRS system and 802.11 WLAN systems using MPLS as the underlying technology is developed. In 4G networks, to suffice the needs of users with relatively low mobility but yet to provide a substantial amount of bandwidth in hot-spots, it becomes essential to integrate WLAN 802.11 systems with currently existing UMTS-GP...
