Performance of BGP Among Mobile Military Networks
Abstract
As tactical military networks deploy new IP-capable radios (e.g., JTRS), it is expected that network connectivity wiII increase both within and among Service and Coalition networking domains (e.g., Army, Navy, NATO). However, unmanaged use of this Increased connectivity may result in violation of some mission-critical operational limits. One mechanism known to (coarsely) manage large-scale IP networks is BGP routing policy. As such, this paper begins the study of BGP's applicability to manage an evolution of the GIG In which IP-based tactical radios proliferate (i.e., the Future GIG). To this end, this paper first presents a modification to BGP that allows for dynamic management of its peering sessions to accommodate network node mobility. Next, since it is known that BGP can have performance issues (e.g., slow convergence), this paper uses network emulation^1 to perform a performance assessment of our modified BGP protocol. Specifically, for ten independent realizations of a mobile wireless networking model, our modified BGP protocol is evaluated with respect to its generated protocol overhead, its ability to develop valid routes to destinations (e.g., reachability), and its influence on network's outage events. Furthermore, our modified BGP protocol is compared to the OSPF and OSPF-MDR routing protocols for mobile networks with increasing number of nodes.
