Abstract: Currently, OpenLISP is an important open source implementation of locator/ID separation protocol (LISP), which implements its full standard features through independent data and control plane. However, OpenLISP doesn't support mobility. The architecture of the OpenLISP was analyzed, and then the data plane was migrated from FreeBSD kernel to Linux kernel and the original OpenLISP to support mobility was extended. Finally, by both fixed and mobile communications, as well as video transmission utilizing VLC media player in mobile scenario, the average delay of ping operation was 1.230 ms and the average handover delay was 2.009 s. The results verified the functionality and performance of OpenLISP for network mobility support.

Key words: OpenLISP, open source implementation of locator/ID separation protocol, locator/ID separation protocol, mobility support
