What is the processor available in cisco 1941 router? is it RISC?

Thank you for your help.

1941 router processor

Hello

http://www.cisco.com/en/US/prod/collateral/routers/ps10538/data_sheet_c78_556319.html

The Cisco 1941 Series is powered by high-performance multi-core processors that support growing demands of branch office networks by supporting high throughput WAN requirements.

The same. Multi-core processor, so I believe it's a regular x86.

1941 router processor

Hello,

Thank you very much for your reply. Our customer has sent one requirement and 1941 router is matching for all specs and customer insisted that

"The architecture should be based on high speed RISC CPU with high port densities"

I have not found any details about processor type from cisco web site.

Thank you,

With regards,

I found a more detailed discussion:

http://www.velocityreviews.com/forums/t34554-cisco-router-processors.html

There is no document to say that model has this CPU, or I could not find it.

Anyway, there is not too much to do in regard to what OS are you runnin gon 1941, so I don't see the requirement regarding the processor to have any impact.

With the port density ... this is another story.

HTH,

Calin

You might suggest to your customer, unless they are planning on programming the CPU, it should matter not what CPU is being used as they are dependent on the vendor code (in this case Cisco's IOS).  They are dependent more on how well Cisco has written their code.  In other words, they could obtain better performance from well written code on a CISC CPU then poorly written code on a RISC CPU.  The real question is, does the 1941 offer the feature and performance they require?

On the question of "high port densities", they should clarify that.  When I think of high port densities for a "router", I think, for example, of the 7600 series, as the latter supports hundreds of routed poor with wire-speed capacity.  ISRs, such as the 1941, support many, many less ports, and for the ports it can support, often can not support a full complement at wire-rate.  In fact, at 1941 rated at about 300 Kpps, cannot guarantee wire-rate performance for a pair of 100 Mbps Ethernet ports.  (Cisco recommends 1941's for up to 25 Mbps of WAN bandwidth.)
