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.

A multi-port switching device architecture decouples decode logic circuitry of each port of a network switch from its respective state machine logic circuitry and organizes the state machine logic as pools of transmit/receive engine resources that are shared by each of the decode logic circuits. Intermediate priority logic of the switching device cooperates with the decode logic and pooled resources to allocate frames among available resources in accordance with predetermined ordering and fairness policies. These policies prevent misordering of frames from a single source while ensuring that all ports in the device are serviced fairly.
