This paper creates a simple mathematical model based on Markov chains which can model (with some simple assumptions) the type of cacheing trees seen in content centric networking. The model is tested with some simulation results.

This paper considers the problem of balancing traffic across network egresses. It achieves a workable solution using a scalable packet market scheme which couples end-hosts controlling their own connection with an overall controller which can select routes appropriately for each flow.
The flows are balanced to seek paths which minimise loss.

This paper looks at the phenomenon of long-range dependence. It shows that certain long-range dependent models give answers which contain infinities and also that this behaviour will not be detected by a naive modelling approach. The work is extended in the JCCS paper

This paper creates software models of how P2P network topologies could wire up. It considers the possible strategies such as connecting to close nodes, connecting to random links and so on. Resilience and delay are considered.

This paper looks at the implementation of a live streaming peer-to-peer video system. The system is a hybrid which can cope with live streaming and video on demand.

This paper looks at monitoring in virtual networks. It introduces an emulated router testbed which can emulate hundreds of routers on networked machines.

This paper looks at the problem of sending data using a variation on Orthogonal Frequency Division Multiplexing. In this variant frequencies are packed slightly closer. This means the frequencies are no longer orthogonal but more may be packed into a given amount of spectrum.

This paper considers the tradeoffs when ISPs collaborate with content providers for mutual benefit.

This paper considers the problems of placing management or monitoring nodes in a dynamic network. It trades off:
1) Selecting long-lived nodes
2) Selecting optimal nodes for traffic (close to the nodes they manage).

Talk to Next Generation Networks meeting -- this talk is partly based on the ICC paper (fundamental relationships in TCP flows) and shows how TCP throughput arises from network parameters and engineering decisions.
