Network-based mobility management for LISP network

Recently, Locator Identifier Separation Protocol (LISP) has been proposed as an efficient approach for dealing with the problem of scalable Internet routing. To support mobility management in LISP network, the host-based mobility management schemes, such as MIP, can be applied. However, the host-based scheme poses additional functional requirements on mobile node (MN), which is highly undesired for practical application. Furthermore, the complicated binding update process of MIP results in relatively large signaling cost and long handoff latency, making the seamless handoff of MNs impermissible. In this paper, the mobility scenario in LISP network is analyzed in detail and a network-based mobility management scheme is proposed for LISP network, which supports mobility transparency and handoff process simplification. The numerical results demonstrate that the proposed scheme offers better handoff performance comparing to the MIP-based scheme.
