This module aims to provide the world with more network architects. The 2011-2012 version was oriented around the evolution of IP to support new services like multicast, mobility, multihoming, pub/sub and, in general, data oriented networking. The course is a paper reading which puts the onus on the student to do the work.

On completion of this module, students should be able to:
- contribute to new network system designs;
- engineer evolutionary changes in network systems;
- identify and repair architectural design flaws in networked systems;
- see that there are no perfect solutions (aside from academic ones) for routing, addressing, naming;
- understand tradeoffs in modularisation and other pressures on clean software systems implementation, and see how the world is changing the proper choices in protocol layering, or non layered or cross-layered.
Assessment is through three graded essays (each chosen individually from a number of suggested or student-chosen topics), as follows:
- Analysis of two different architectures for a particular
scenario in terms of cost/performance tradeoffs for some
functionality and design dimension, for example:
- ATM – e.g. for hardware versus software tradeoff
- IP – e.g. for mobility, multi-homing, multicast, multipath
- 3GPP – e.g. for plain complexity versus complicatedness
- A discursive essay on a specific communications systems component, in a particular context, such as ad hoc routing, or wireless sensor networks.
- A bespoke network design for a narrow, well specified specialised target
scenario, for example:
- A customer baggage tracking network for an airport.
- in-flight entertainment system.
- in-car network for monitoring and control.
- inter-car sensor/control network for automatic highways.
This course does not feature any implementation work due to time constraints.
- Three 1,200-word essays (worth 25% each), and
- an annotated bibliography (25%).
