Agent-based virtual private networks architecture (ABVA) refers to the environment where a third-party provider runs and administers remote access virtual private network (VPN) service for organizations that do not want to maintain their own in-house VPN servers. In this paper, we consider the problem of optimally connecting users of an organization to VPN server locations in an ABVA environment so...
This paper investigates and analyses the dynamics engendered by the engineering of self-organisation in a global Service Oriented Architecture. The effects are assessed via a resource allocation algorithm for load balancing, based on the observed behaviour of foraging honeybees. It is implemented at the application layer of a simulated server farm type system and its impact is investigated across...
In this paper, we propose and study how to provide multipath cross-layer service discovery (MCSD) for mobile ad hoc networks (MANETs). Cross-layer service discovery integrates service discovery into route discovery by taking advantage of network-layer topology information and routing message exchange. Multipath service discovery differs from multipath routing in that multipath service discovery can...
The complexity and dynamics of Border Gateway Protocol (BGP), the only inter-domain routing protocol available for the Internet, is driving the need for efficient, scalable, realistic and meaningful network simulations. To properly simulate the behavior of BGP as currently deployed, one requires both a realistic topology and a realistic model of BGP. Although a large number of topology generators...
