Re: [c-nsp] Understanding ASR1k / ESP40 capacity
Think not only throughput but about pps also. According to cisco doc ESP40 has ~24Mpps capacity, ESP20 has the same limitation. So, you pick out all resources from QFP.

Re: [c-nsp] Understanding ASR1k / ESP40 capacity
SIP40 supports 46Gbps through the backplane to the ESP. This is through 2x 23Gbps channels. What I don't know is how the channels connect to the SIP/SPA. I don't think it's one channel per SPA slot, so there has to be some sort of hashing internally. Perhaps a single channel is being oversubscribed (this will probably be tough to determine)? Off the top of my head the only other possibility I can think of is a feature issue. The QFP is a processor at the end of the day, so it's possible that the features you have enabled are taking enough to add extra overhead, maybe due to small packet sizes (more lookups to achieve the same throughput)? Another option is that the QFP is multicore and maybe it's dispatching to the cores unequally? All of these are kind of out there ideas, but just some other things you could bring up. -Pete On Mon, Oct 6, 2014 at 11:24 AM, Simon Lockhart si...@slimey.org wrote: Pete, Thanks for this - I'll watch that preso and see if it adds anything useful.

Re: [c-nsp] Understanding ASR1k / ESP40 capacity
Hi Simon, In the presentation Steven specifically mentioned at around 35min when talking about sys bw that all you care about is the capacity of the link between the QFP and the central buss -that link is full duplex (shame I could not find it written anywhere in the docs). So if the QFP is e.g. 10 gig that link is 10gbps+overhead so if you have 10gig coming in from any of the IOs you're done. Getting it out doesn't count as the link is full duplex so once you can get it in you can get it out. So this supports your claims that you should be able to get 40gbps full-duplex out of the QFP i.e. 40gig in and 40gig out. adam -Original Message- From: cisco-nsp [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Simon Lockhart Sent: Monday, October 06, 2014 5:25 PM To: Pete Lumbis Cc: cisco-nsp@puck.nether.net Subject: Re: [c-nsp] Understanding ASR1k / ESP40 capacity Pete, Thanks for this - I'll watch that preso and see if it adds anything useful.

Re: [c-nsp] Understanding ASR1k / ESP40 capacity
According to cisco's literature the 40G capacity is outbound direction only. This includes traffic replication so you could have 1G in and 40G out or 50G in and 40G out but you should be able to get 40G out unless you are using features that are causing core congestion on the QFP (which is possible).

[c-nsp] Understanding ASR1k / ESP40 capacity

Re: [c-nsp] Understanding ASR1k / ESP40 capacity
It would be a single pass through the QFP. The SIP could also be a limiting factor, but since you are split between SIPs that shouldn't be an issue. The SIP 40 has 2x 40Gig lanes on the backplane. Are you doing crypto or anything like that which would impact performance? There is a great Cisco Live preso on the ASR1k architecture that might help you get some ammo to go back to TAC with. http://d2zmdbbm9feqrf.cloudfront.net/2014/usa/pdf/BRKARC-2001.pdf -Pete On Sat, Oct 4, 2014 at 4:56 AM, Simon Lockhart si...@slimey.org wrote: All, I'm banging my head against a brick wall trying to get sensible answers from Cisco TAC, so thought I'd ask the educated masses who may have come across this before...
