Abstract
ve topology measurements on the African Internet have showed that over 75% of the intra-Africa traffic destined for Africa’s National Research and Education Networks (NRENs) uses intercontinental links, resulting in high latencies and data transmission costs. The goal of this work is to investigate how latency-based path selection using Locator/Identifier Separation Protocol (LISP) and Software Defined Networking (SDN) in NRENs can be used to reduce inter-NREN latencies. We present aspects of an experimental prototype implementation for real-time topology probes to discover lower-latency remote gateways and dynamic configuration of end-to-end Internet paths. Simulation results indicate that ranking remote ingress gateways, and dynamic configuration of end-to-end paths between gateways can lower the average latency for inter-NREN traffic exchange.
