This paper looks at the issue of reducing variability in performance
in data centre networks. Variable network performance can lead
to unreliable application performance in networked applications –
this can be a particular problem for cloud apps. Virtual networks
are proposed as a solution to isolate the “tenant” performance from
the physical network infrastructure. The system presented is known
as Oktopus. The system provides a tradeoff between guarantees to tenants,
costs to tenants and profits to providers by mapping a virtual network
to the physical network.

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
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.
