An Instant Messaging security system that encrypts Instant Messages sent by a Instant Messaging user to an Instant Messaging server by intercepting the messages, negotiating a preferred security algorithm and forwarding the encrypted messages to the server. The security system intercepts and decrypts encrypted messages sent by the server to the user. The security system is able to determine whether a receiving user is equipped with a similar security system without prior knowledge of network addresses, configuration or capability. The security system is transparent to the Instant Message service provider and may provide one or more indicators to users that messages are encrypted during forwarding.

System, device and method for dynamically securing instant messages

Methods and systems for determining paths for flows within a multi-stage network made up of clusters of processing nodes. The flow paths may be determined without knowledge of whether or not packets of a particular flow will actually traverse specific ones of the clusters within the multi-stage network. In various implementations, the nodes of the multi-stage network may be coupled to one or more physical network switches through respective physical interfaces and a virtual connectivity grid superimposed thereon and configured through the use of a flow routing framework and system management framework to group the nodes into a number of clusters. The nodes of each cluster are configured to perform similar packet processing functions and the clusters are interconnected through virtual networks to which the nodes are communicatively coupled via virtual interfaces overlaid on top of the physical network interfaces.
