QUALITY OF SERVICE: A MECHANISM FOR EXPLICIT ACTIVATION OF IP SERVICES BASED ON RSVP

Dimitrios Kagklis - Christos Tsakiris - Nicolas Liampotis

   Internet Protocol-based applications are the prevailing trend of the telecommunications market, but the path towards the "IP over everything" target is not unhampered. The main shortcoming of the IP protocol is its incapability of providing guaranteed Quality of Service (QoS). We propose a mechanism, which is based on the RSVP protocol, that provides the customer with means to request services with specific characteristics and the service provider with methods to supply these services with guaranteed QoS, as well as, to manage the network resources in order to support the requested levels of QoS.

Keywords: IP, QoS, Services, SLA-SLS, Signaling, RSVP
