Label switched packet transfer for wireless cellular networks

“…The proposed protocol builds on the IEEE 802.11 MAC and uses MPLS like labels in the control packets to allow the forwarding node to determine the next hop node while contending for the channel. Jabbari et at [2] have developed the Label Switched Packet Transfer (LSPT), which provides a hierarchical architecture to use label switching to support wireless mobile terminals. This architecture provides efficient packet transfer over mobile wireless networks by efficiently allocating wireless resources.…”

We consider a campus environment connected using multiple WLANs and WLAN routers providing interconnection between the W A N networks. Servers part of WLANs in a campus network provide various services to users across the network. In this paper, we have extended our earlier work related to service-and session-specific labeling, path, and switching. The extension is to support service-specific QoS and this is achieved by idenhbing an SSP Tree (a collection of SSPs) rooted at the WLAN router connected to the server hosting the service. Fur?her, the service QoS parameters are dishibuted across the SSP Tree for network resource reservations purposes. This reserved SSP Tree is used to set up bi-directional QoSsupported session-specific paths.

“…1 these IP packets would be encapsulated with two additional IP headers, resulting in a poor efficiency. The use of MPLS in the UTRAN has been considered mainly in terms of protocol functionality, for example: mapping of traffic flows to MPLS Label Switched Paths (LSPs) and signaling for LSP establishment [14], combination of MPLS traffic engineering (MPLS-TE) functions with the Differentiated Services model (DiffServ) [15], and mobility support [16], [17]. These references point out potential advantages of MPLS for transport in the UTRAN, but no numerical results are presented.…”

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.
