Abstract: A system, comprising a plurality of geographically distributed colocation facilities (colos), each colo comprising a plurality of computing devices configured to establish local connections between the colo and user devices associated with a corresponding set of users; maintain local connection state information relating to the local connections; maintain remote connection state information relating to remote connections between other ones of the colos and user devices associated with the corresponding sets of users; and facilitate sessions between any of the user devices connected to any of the colos with reference to the local and remote connection state information.

Abstract: Systems and methods are provided for multiple points of presence (MPOP) in the real time communication of data between or among users. More particularly, according to embodiments of the present invention, a messaging service network is provided that allows a user to connect to the messaging service network from multiple client devices and access features associated with the messaging service network from any one of the multiple client devices at any point in time. In this manner, a user can seamlessly transition among multiple client devices without interruption and access services provided by the messaging service network including, but not limited to, sending/receiving instant message (or “IM”) data to other user(s), publishing/subscribing presence to other user(s), making/receiving phone calls between user(s), etc.
