Hierarchical Mobility Label Based Network: System model and performance analysis

Hierarchical Mobility Label Based Network (H-MLBN) is a new approach to the network layer mobility management problem that relies on MPLS-aware control plane and MPLS-based forwarding plane to provide IP mobility support for IPv4 and IPv6 mobile hosts and routers while being able to ensure optimal traffic delivery between the communicating devices. The hierarchical system is capable of both macro- and micro-mobility support without the use of Mobile IP and its derivatives thus eliminating the user and network facing performance penalties associated with triangular routing and bi-directional tunneling. This paper presents a system model and provides performance analysis for H-MLBN and compares its performance with the Mobile IP based schemes. The results indicate significant performance improvements in the forwarding plane traffic delivery as well as the control plane network update costs.

Mobility label based network: Hierarchical mobility management and packet forwarding architecture

Scalability of the network layer mobility management solution is one of the most important requirements for the mobility control plane. Mobility Label Based Network (MLBN) is a new approach to the network layer mobility management problem that relies solely on MPLS to provide both macro- and micro-mobility for IPv4 and IPv6 mobile hosts and routers. This new approach does not rely on the existing IP mobility management protocols such as Mobile IP and is based on the combination of Multi-Protocol BGP (MP-BGP) and MPLS. In the context of the MLBN the scalable control plane should be capable of efficient Mobility Label distribution while allowing the MPLS-based forwarding plane to deliver mobile traffic in an optimal manner. This paper presents a hierarchical mobility management system capable of both macro- and micro-mobility support without the use of Mobile IP and its derivatives and allows scalable Mobility Label distribution and MPLS label stack based packet forwarding in support of optimal traffic delivery between the communicating mobile users.

Seamless mobility across IP networks using Mobile IP

The landscape of today's telecommunications portrays an amazing patchwork of heterogeneous networks, with very few and complex bridges between them. In this context, IP technology has emerged as a natural means of initiating network convergence and the “All-IP” paradigm has become the implicit assumption for most studies on the next generation architecture design. However, the real added value of such networks from the user's point of view will lie in offering seamless and transparent services through any kind of network. This can only be achieved with a global solution for mobility management and some believe it to be Mobile IP. The purpose of this paper is to describe how the EURESCOM project P1013 FIT-MIP has evaluated the use of Mobile IP acting as a mobility management protocol federating various access network technologies such as PSTN, Wireless LAN or General Packet Radio System. The use of Mobile IP as the enabler for inter-access technology handoffs will be the first step towards providing always-on access to IP applications (e.g., VoIP, VPN, mobile Internet).
