SIP card in ASR 9K

[aircel.dishnet]

Hi all ,

Whether SIP-601 or SIP-600 will support in ASR9K or not ?

thanks,

Arun,

No, neither the SIP-601 nor SIP-600 will work in the ASR9k.  The ASR9k has it's own SIP to work with its backplane.  The SIP-700 will support most of the SPAs that the GSR with SIP-600/1 would.

Hi Bryan,

thanks for your swift response.

Can you please tell the maximum throughtput of SIP-700

thanks,

hi arun, that LC is rated at 20G each direction.

(enough to drive OC192)

Hi Alex,

thanks for your great reply.So it is having 20G full duplex capacity.

Can we insert the SPA cards whoes total capacity is above 20G in SIP-700.If yes then what is the maximum limit.

Thanks,

Arun Mohan

hi Arun, the SPA's that the SIP700 for a9k supports dont go beyond 10G, and truth is the oc192 is a half height one so you can only have 2 of them in the 4 bay sip700.

you cannot oversubscribe the marmot (spa driver sitting before the hw forwarder/CPP).

so you have 20G in each direction which suffices for 2 SPA's of OC192.

cheers!

I think I have a good picture here that describes the HW diagram of the SIP700

To make a comparison to Trident Linecards for the ASR9000:

Octopus is the fabric interface asic (also present on trident)

Serpent is the birdge from fabric "protocol" to the CPP, which consists of 2 components (popeye/spinach whcih is for forwarding and BQS).

BQS is buffer queueing and scheduling

Marmot is the SPA driver converting spa talk to CPP speak.

CPP is the CPP10, same as in ASR1K (older service engines though)

A control/LC cpu is present, same as the trident linecard with a punt FPGA called HYTOP.

So bottleneck is the link between marmot and cpp which is 10G. Marmot can do 20G.

There are 2 CPP's, 20G each, one per direction.

helps?
