From Cisco's:
technology preview of Cisco's new family of gigabit switch routers (GSRs) providing high performance solutions ranging from 5 to 60 Gb/s for Internet and large-scale WAN Intranet backbone applications.
Now, I've got a GRF 400 with the ATM OC-3c card, the FDDI card, and the 10/100Base-T card. It works flawlessly. And I can't honestly see how the
Also, not that I know anything about the GRF but I think Cisco claims that 7500 real-world performance is much better than the GRF400.
I've had cisco sales reps claim even more ludicrous things while the support engineer started turning red, so who knows...
hi, Ok. since no one else bothered to post real numbers here are some: Cisco numbers: ============= Cisco 7500 Ascend GRF Performance 2 Gbps 4 Gbps System Bandwidth 1.4 Mpps 2.8 Mpps Theoretical Performance with 65 - 85 Kpps 35 - 70 Kpps 180 byte (Bi-directional) (Bi-directional) packets Line Card Forwarding 325 Kpps 280 Kpps Rate (7507 w/ 5 VIP.s) (Fully Loaded) Real Performance Performance w/ Services 880 - 1000 Kpps 140 - 210 Kpps Routing Table Size 250,000 + 150,000 + The tolly/ascend report numbers: =============================== looking at their data (n.t. = not tested): # of modules cisco 7514 w/rsp4 GRF1600 GRF400 --------------------------------------------------------------- 1 122,300 60,388 59,731 2 244,520 120,848 119,348 3 366,516 n.t. n.t. 4 368,575 241,516 236,776 6 367,774 360,000 8 367,302 483,016 16 n.t. 965,424 Using Random IP- in this test the routers were re-booted and the performance measured at 15 minutes after boot time. also, destination IP addresses were varied by randomly generating class c dest. addresses. random ip test (at +15 min. after boot): # of modules cisco 7513 w/rsp4 GRF1600 ------------------------------------------------ 1 41,096 54,454 2 84,504 107,720 3 72,762 162,750 4 86,654 217,700 5 71,867 265,500 So, who's numbers should we believe or feel are more appropriate to real world situations?
Comparing GateD to IOS becomes more of a religious preference than anything else. I'm content knowing both, truth be told.
maybe someone can post some performance numbers.
