Optimizing request denial and latency in an agent-based VPN architecture

—Agent-based virtual private networks architecture (ABVA) refers to the environment where a third-party provider runs and administers remote access VPN service for organizations that do not want to maintain their own in-house VPN servers. This environment presents interesting management challenges for an ABVA provider. In this paper, we consider the problem of connecting users of an organization to an optimal VPN server location so that request denial probability and latency are balanced. Because of the bandwidth requirement of a user to be met when connected to a server, this system has the appearance of a standard loss system. However, due to latency perceived by a user from its current location to a VPN server and to allow for servers to be located in a distributed fashion, this environment is not a pure loss system. By considering a finite population, this environment can be approximately represented using the Engset model; however, this does not address the latency issue either...
