Re: [j-nsp] MPC3E oversubscribe rate with two 10x10GE MICs
As I understand it, it is still split 50/50% wise. Two active MIC slots arbitrate equally for packet processing resources, regardless of how much bandwidth they could potentially (or not) use. A 20x1G MIC will essentially waste 40G of throughput.

Re: [j-nsp] MPC3E oversubscribe rate with two 10x10GE MICs
Nope. If you have enough bandwidth available you can use both 1x100G+2x10G mics linerate (same for 10x10G+20x1G). Yet what may make the difference is rather the packet size and pps. If you have a high rate of 64bytes packets you may encounter drops on the 1x100G mic. Yet I am not sure of this. This is what happens on MPC4E combo cards for the port 4x10G and 1x100G that share the same ASIC (See David Roy's web site junosandme for further explanations) Envoyé depuis mon Radiocom 3000 Message d'origine De : Tom Storey t...@snnap.net Date : A : Olivier Benghozi olivier.bengh...@wifirst.fr Cc : juniper-nsp@puck.nether.net Objet : Re: [j-nsp] MPC3E oversubscribe rate with two 10x10GE MICs As I understand it, it is still split 50/50% wise.

Re: [j-nsp] MPC3E oversubscribe rate with two 10x10GE MICs
The 16x10G MPC is not quite line rate full duplex because the PFE processing capacity is a little over 70G total per 4 ports. If the traffic is internal to the PFE it doesn't count towards that. If your ports are mostly incoming traffic or outgoing its not an issue,but if you truly had bidirectional high traffic levels you will get about 35G in each direction if it is all headed to/from the fabric. Also on the MX960 at least the fabric connection is only about 38G so you wont get a full 40G line rate in one direction either.
