1. An apparatus for ensuring quality-of-service in a network, said apparatus comprising:
- at least one first stream sender having at least one flow control parameter;
at least one first stream transmitted from said first stream sender;
a network interconnection receiving said first stream from said first stream sender and at least one second stream transmitted from a second stream sender;
a bandwidth control being associated with said network interconnection; and
said bandwidth control adjusting said flow control parameter of said first stream sender for supporting at least one performance parameter associated with said second stream.

Abstract
An apparatus for ensuring quality-of-service in a network is provided. A first stream sender having a flow control parameter and transmitting a first stream. A network interconnection receiving the first stream and a second stream. First stream being a non-realtime stream and the second stream being a realtime stream. A bandwidth control being associated with the network interconnection. The bandwidth control adjusting the flow control parameter for supporting quality-of-service parameters associated with the second stream.
