This paper deals with the problem of ISPs selling contracts to other
(customer) ISPs. Transit ISPs implement policies which price traffic
by volume or by destination with volume discount and cheaper prices
to destinations which cost them less. The paper studies destination
based tiered pricing with the idea that ISPs should unbundle traffic
and sell pricing in tiers according to destination to maximise profits.
The background section offers a useful taxonomy of current bundles
sold by transit ISPs. This arises from discussions with ISPs.

This paper looks at the problem of accessing services on a network
which are potentially geographically distributed (for example, the
closest server for a particular service). Serval allows the
discovery of end-points for services and allows them to seamlessly
migrate so ‘‘end-points can seamlessly change network addresses,
migrate flows across interfaces… [with] uninterrupted service access."
Serval runs on an unmodified network layer. Application communicate
with service names (identifying the changing group of hosts
providing a service) not addresses and ports.

Paper advocates decoupling of network architecture from network
infrastructure – Software Defined Internet Architecture (SDIA).
Problem is to allow new architectures without falling back to a
“clean slate” deployment.

This paper looks at time-dependent pricing schemes. A day is
split into 48 half hour periods indexed by
an integer. The system is known as TUBE (Time-dependent Usage-based
They use a control loop to adapt the prices ISPs charge users

Open Radio is a design for a programmable wireless dataplane. Wireless
protocols evolve quickly and infrastructure for wireless must support
this. Protocol changes are continuous but many basestations deployed.
OpenRadio exposes an interface to program PHY and MAC layers.

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.
