  • 摘要:Voice over IP (VoIP) wastes a valuable amount of bandwidth because ofits large packet header size compared to its small packet payload. The main objectiveof this paper is to reduce the amount of this wasted bandwidth, by proposing a newpackets coalescence method, called Payload Shrinking and Packets Coalesce(PS-PC). The proposed PS-PC method reduces the amount of the wasted bandwidthby i) coalesces a group of VoIP packets in one header instead of a separate headerto each packet and ii) shrinks the VoIP packet payload to a smaller one based on acertain algorithm. The proposed PS-PC method is deployed at the sender side VoIPgateway that represents an exit point to a myriad number of simultaneous VoIP calls.The performance evaluation showed better bandwidth usage when deploying theproposed PS-PC method with ITTP protocol in comparison to the traditional ITTPprotocol without the PS-PC method.
