Multipath routing gives traffic demands an opportunity to use multiple paths through a network. In a single-demand situation, its benefits are easy to see. In a multi-commodity case, when potentially all node-pairs (demands) generate traffic, they compete for the same network resources. In this work, we consider multipath routing in communication networks in a multi-commodity setting from a traffic...
A secure network is considered to be an important goal of the Future Internet; one way which can be embodied is by having flexible and robust routing functionality with built-in security and trustworthy mechanisms. However, there is a fundamental and important challenge how to determine the trustworthiness to every traffic flow to realize trustable communications. In this paper, we propose a framework...
A secure network is considered to be an important goal of the Future Internet; one way this can be embodied is by having flexible and robust routing functionalities with intrinsic security mechanisms. It is also desirable to provide user-centric or service-centric routing capabilities to achieve service-oriented traffic controls as well as trust and policy management for security. Based on these potential...
Great Plains Environment for Network Innovation (GpENI) is an international testbed for future Internet research. A key component of GpENI is programmable network virtualization (GpENI-VINI). The scope of this paper is to present the framework, implementation and integration experience with network virtualization in GpENI. In particular, this is described through our experience of implementing and...
Number portability provides users the capability to keep their telephone numbers as they moves to another provider. Number portability technology involves complicated architecture between different providers. From a routing perspective, and in order to simplify the model, we consider that the traversal of a call to a ported number may involve three different networks: the Originating Network, the...
The co-existence and integration of different wireless networks will significantly advance the provision of ubiquitous and high-performance Internet services to mobile users. In this paper, we present HAWK, a real-world implementation of high performance heterogeneous wireless networks for ubiquitous Internet access. We have built a fully featured testbed comprised of different wireless networks,...
