Guidelines

The term Differentiated Services is used to denote different requirements of various network services for bandwidth, latency and reliability of packet transport on a shared medium. The thesis aims to design and measure a novel traffic scheduler for internet-related packet switching networks that would improve network behavior in presence of Differentiated Services.

The design builds on active queue management techniques similar to CoDel and SFQ, and improves the handling of Differentiated Services in two ways: First, the scheduler is basically knobless, handling any new kinds of services without modification or reconfiguration, and second, it is simple enough to be placed at the exact bottlenecks of packet-switching networks where it can precisely react to network deficiencies and prevent impact on the quality of delivered service. The new scheduler will be implemented, tested and evaluated in a simulated computer network.
