Bandwidth Allocation and Session Scheduling Using SIP

Category: Software and Web Development, Networking and Communications

Overview Session Initiation Protocol (SIP) is a new signaling protocol designed to establish multimedia sessions in telecommunication networks. This paper suggests the extension of SIP functionalities to coordinate QoS mechanisms deployed in IP networks, and especially in DiffServ domain. Indeed, the interaction between small and big TCP sessions may have dramatic consequences on small TCP sessions. Hence, the paper uses SIP to achieve QoS management on a session basis, in which the over all activity of the user during the session is considered. The suggested mechanisms deal with two issues: first, session scheduling based on session duration and/or volume, and second bandwidth allocation on a per-flow basis using equivalent bandwidth estimation techniques.

Just like major corporations, small and midsize businesses (SMBs) are increasingly reliant on the critical data stored on their servers. Limited resources and vulnerability to interruptions put small and midsize businesses at higher risk, and relying on native backup for a small business server can leave gaps in the disaster recovery plan.
