Online traffic engineering by optimizing inbound traffic in locator/identifier separation context

To cope with the scalability issue of current Internet inter-domain routing system, several proposals addressing identifier and locator separation are proposed recently. LISP is one of them. In a LISP-capable network, when end-system identifier (EID) is not routable, a mapping system must map an EID to a routing locator (RLOC). By optimizing EID-RLOC Mapping Assignment (ERMA) for an AS, inbound traffic can be optimally distributed in the AS. In this paper, ERMA optimization problem is studied. We introduced an online ERMAO scheme based on delay information of probe packets. Simulation results show that online optimizing ERMA can achieve better network performance, e.g., lower packet delay and maximum link utilization.
