Presence and its effect on network

Presence is the ability to provide real-time information about a user. Presence can be based on geography (i.e. information based on physical locations) or reachability (i.e. how a user can be reached based on the type of device used) or retrieving information intelligently (e.g. call forwarding in call centers). Multi-resource presence-aware communication, by definition, implies communication solutions that incorporate presence awareness at a device, user, and group level. The study of presence services lead to the fact that the means of transferring data is one of the most important factors while providing presence services. The auxiliary technology necessary to launch presence services is discussed in this paper. A careful study of the threats and impact on network resource consumption is presented in this paper, to overcome the fundamental hurdles of manageability and security. The issues discussed are useful for the service providers so that they are on the right side of the instant messaging (IM) revolution. This paper also focuses on inherent real-time nature of IM and presence and tries to logically bridge the gap between telephone and the rich data infrastructure.
