Improving QoS for VoIP session establishment with SIP channel reallocation scheme Presentation by:Anil Kumar Marikukala Syed Khaja Najmuddin Ahmed
Outline: • Introduction. • Reasons for SIP Trunk failure. • Consequencesof SIP trunk failure. • SIP Trunking demo. • Mechanisms to improve QoS. • Preferred solution. • Future research.
Introduction: • SIP : Session Initiation Protocol. • Used to establish a session between two users. • Establishes session using SIP Trunk.
Reasons for SIP Trunk failure: • Overflow of the network. • An improper telephony solution. • Physical damage.
consequencesof trunk failure: • Users looses connection during the call. • It is difficult to get back the trunk as it involves knowledge of whole network skeleton.
SIP TRUnking demo: • SIP Trunk established between two Asterisk machines.
mechanisms to improve QOS: • Three Enhanced Priority schemes: • One Server/Four Trunk Scenario. • Four Server/Four Trunk Scenario. • Four Server/One Trunk Scenario.
Preferred solution: • We prefer 3rd scenario => Four Server/One Trunk Scenario. • Because of a block which decides the distribution of traffic in trunks.
Future research: • The EPS module algorithm. • Compatible with different protocols. • Exceptions can be add to the module to reject the unwanted traffic.
