| Today's Internet leacks the mechanisms
necessary for traffic isolation (to divide resources fairly) and
differentiation (to allocate resources to users according to
their willingness to pay). In this work, we present a new
architecture for relative service differentiation, Scalable Share
Differentiation (SSD), which allocates network resources on a
user basis and properly provides for both elastic and real-time
traffic isolation and meaningful differentiation. SSD does not
require the storage of any per-flow or per-user information at
the core nodes and is inherently designed to work without
admission control, making it easier to deploy and manage. In
addition, we present how to provide more fine-grained flow
control to users without changing the concepts of SSD, which
permits users to choose different priorities for their
packets/flows. This allows the integration of a novel concept for
improving the service quality given to user flows: user-based
admission control. With user-based admission control, the network
is unaware of admission control decisions, and the user himself
can perform the tasks of accepting, rejecting and prioritizing
flows. |
