This is the same design for MPC6e PFE and I didn't see any issue with this design. I also didn't see any specific issue due to this design in POC where we stressed the PFE. XL ressources are just shared. For Inter XM forwarding, the shared XL is not used but the fabric links is used.

I'd love to see how arbitration as well as backpressure is done in this case since now two independent arbiters(since arbiter is in XM) are going to fight over XL resources. adam Adam Vitkovsky IP Engineer T: 0333 006 5936 E: adam.vitkov...@gamma.co.uk W: www.gamma.co.uk This is an email from Gamma Telecom Ltd, trading as “Gamma”.
