Cisco routers throughput

[Jonn cos]

Hi all,

I have seen datasheets of various equipments and usually i see throughput of all of them. What is surprising that cisco hasnt shown throughput of routers in datasheets.

I am just curious, why is this so ? can someone from cisco highlight this ?

Here they are: http://www.cisco.com/web/partners/downloads/765/tools/quickreference/routerperformance.pdf

This one include IPv6 too: http://www.cisco.com/web/strategy/docs/gov/IPv6perf_wp1f.pdf

Its saying that 1941's throughput is 2932 Mbps does it mean 2 Gbps ?

[Andras Dosztal]

I don't know where you saw that, the first linked document states the 1941 can process 299,000 packets/s and 153.08 Mbps. Please note that this performance can decrease by using more services of the router.

Assuming you saw that in table 1 of Cisco's Cisco Integrated Services Routers—Performance Overview white paper, 2,932 Mbps also means 2.932 Gbps.

I mean sir which document shall be followed if i am asked by a client to tell them potential throughputs of routers ? how am i supposed to tell them ?

Since you guys are more experienced, when such queries arrives, how do you handle them

Hello John,

http://anticisco.ru/pubs/ISR_G2_Perfomance.pdf

1941

- no services, just routing

throughput 1500B packets - 2.932Gbps

- firewall performance

max throughput - 569Mbps

100 concurrent sessions throughput - 63Mbps

- HQoS Performance by Platform; IMIX Traffic at 75-Percent CPU

throughput - 120Mbps

- PAT Performance by Platform, IMIX Traffic at 75-Percent CPU

throughput - 91Mbps

- NAT + QoS + ACL Performance by Platform, IMIX Traffic at 75-Percent CPU

throughput - 76Mbps

You can see how throughput is decreasing after enabling more and more services. Max throughput is almost 3Gbps but it is not value which you will achieve in real network.

Best Regards

Well I've used the (older) document Andras provided, usually I would recommend not to exceed about 25% of the bandwidth noted on that document.

With the (newer) document John references, I usually recommend a platform one or two sizes down from the recommendations in the last table, unless I really expect it to routinely run at full "WAN" rate.
