Abstract
Network control is decomposed in six parts: switch control,
resource partitioning, virtual network building, virtual network
control, generic services and data-path components. Each of these parts
can benefit from support for dynamically loadable code, which allows
users to extend and customise the basic functionality. This is related
to active networks, except that dynamic code exercises control mostly at
the granularity of connections (flows), rather than individual packets
and all aspects of network control are explicitly considered. Network
resources are recursively partitionable, so that dynamic code is able to
control partitions of virtual networks in any way it sees fit. Policing
these partitions may occur at varying levels of 'strictness'.
Keywords: Active networks, elastic control, open control, virtual networks, policing
