RSVP is an Internet protocol designed to reserve network resources. Availability of optimized free implementations of RSVP daemon and the development of extensions designed to improve RSVP's behaviour have increased the attention towards the protocol. Though RSVP has been designed to fulfill QoS needs of multimedia applications, development of compliant applications is slowed by complexity of logic behind the access to QoS. This paper describes the current problems related to the deployment of RSVP into multimedia applications and the QOSMIC architecture in support to multimedia applications that tries to solve these problems. The QOSMIC elements allow a user to reserve resources without requiring the update of multimedia applications neither on the client side nor on the server one, allow a receiving user to require RSVP Path messages needed to start reservations and allow a centralized management of QoS.

Abstract
RSVP is an Internet protocol designed to reserve network resources. Availability of optimized free implementations of RSVP daemon and the development of extensions designed to improve RSVP's behaviour have increased the attention towards the protocol. Though RSVP has been designed to fulfill QoS needs of multimedia applications, development of compliant applications is slowed by complexity of logic behind the access to QoS. This paper describes the current problems related to the deployment of RSVP into multimedia applications and the QOSMIC architecture in support to multimedia applications that tries to solve these problems. The QOSMIC elements allow a user to reserve resources without requiring the update of multimedia applications neither on the client side nor on the server one, allow a receiving user to require RSVP Path messages needed to start reservations and allow a centralized management of QoS. A test implementation of QOSMIC is also briefly described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
