Abstract
VoIP network is proliferating worldwide in lightning pace. As it grows and matures in terms of number of users and variety of services, it faces the burden of overcrowding, overload and service sustenance challenges. In a typical scenario of recovery from a network-wide power outage, the VoIP telephony servers may face sudden and huge load of service requests coming from the users. This may lead to unwanted situations like congestion, service delay, service disruption, etc. causing a potentially disastrous revenue loss for the service providers. In usual overload control mechanism, valuable system resource is spent in constantly monitoring the traffic and performing additional work if an overload is detected. This may prove costly and ineffective under extreme load conditions. This paper presents a simple and novel way of handling very heavy load without any overload control overhead. We employ the inherent characteristics of IP and H.323 networks to handle sudden and extreme load in a H.323 based VoIP network, providing a cost effective disaster recovery solution
