QoSockets; a new extension to the sockets API for end-to-end application QoS management

摘要

The key question addressed by this paper is how multimedia applications can adapt to the QoS delivered by the network and vice versa. QoSockets is an extension to the sockets mechanism, to enable QoS reservation and man- agement. QoSockets automatically generates the instrumentation to monitor QoS. QoSockets mediates interactions among applications and transport protocols, and collects in QoS MIBs statistics on the QoS delivered. The main advantages are: support of single API for transport layer QoS negotiation, connection establishment, and data transmission; support of a single QoS negotiation protocol; generality across application QoS needs; and automatic management of application QoS needs.
