Re: [ixp1200] L3fwd16 communication between SA and ME

The core and ME pass packets through ME->Core and Core->ME rings. The ME dispatch loop queues exception packets to the ME->Core ring, which is polled by a Resource Manager thread. It consumes the packet from the ring and produces it on the ring of the Core component of the MicroAce. For communication in the other direction, the Core component uses the RM driver to enqueue the packet in the Core->ME ring, which is then consumed by thread(s) on the microengine using dispatch loop macros. -- abhijeet On Sun, 16 Mar 2003, Eng Kean wrote:
