An integrated multiflow network model synthesizing physical layer rate control and link layer access control is presented, permitting the study of resource allocation in large networks while allowing multi-terminal cooperation at the physical layer. We discuss how to incorporate the cooperative unit into the broader scheduling and routing framework as a “metalink,” a general notion capable of r...

The rapid growth of peer-to-peer networks and social networking websites has demonstrated the internet’s potential as a medium for grassroots collaboration. This report describes ongoing research into the use of friend-to-friend overlay networks for censorship-resistant communication. Decentralised mechanisms for resource allocation, unforgeable acknowledgements and adaptive routing are propose...

We consider the question of how routing and allocation can be coordinated to meet the challenge of demand variability in a parallel queueing system serving two types of customers. A decision-maker decides whether to keep customers at the station at which they arrived or to reroute them to the other station. At the same time, the decision-maker has two servers and must decide where to allocate t...

In present work we address a problem of optimal resource partitioning in high-speed network with heterogeneous traffic classes and differentiated QoS requirements. The problem arguments are bandwidth and network-edge buffer space allocations for end-to-end connections. The problem formulation can take into account sensitivity variation of application performance for both aggregated and single s...

The Internet has become a key infrastructure for global information society. However, the availability of the Internet can be substantially challenged when a disaster strikes, because in such cases the recovery process as of today is largely manual, slow and inefficient. Recognizing that a key issue for obtaining availability is to find the connectivity to the lost destinations, we exploit Inte...
