The embodiments described herein provide mechanism that allows an embedded router software image and an application to run in the user application memory space of a general purpose computer. A connection is established with an operating system device configured to route packets between the application and the software router and route, by the software router, network traffic to and from the application by way of the connection. The application may be connected to other applications in the user application memory space or connected to applications that are external to the general purpose computer.

Routing traffic for applications by a software router co-resident in application memory space of a general purpose computer

The embodiments described herein provide mechanism that allows an embedded router software image to run in the user application memory space of a general purpose computer. An interface process is provided to receive and transmit packets between the user application memory space and the operating system's protected or kernel memory space of the general purpose computer. The interface process mimics or emulates any hardware interfaces that would be available to the router software when running on a dedicated embedded router device.

Group key management in a mobile ad-hoc network (MANET) may be provided. Each network node associated with the MANET may comprise a group distribution key and a list of authorized member nodes from which a group key manager may be elected. The group key manager may periodically issue a new group key to be used in protecting communications among the network nodes. A compromised node may be excluded from receiving updated group keys and thus isolated from the MANET.
