Re: My impressions of Juniper from the test lab
Dave, We can test and compare apple with oranges in that respect. Why?. GSR internal architecture is based on shared bus/cpu while GSR using distributed, cross-bar architecture. Therefore, to perform the test fairly you should load the M-xx with PIC's and the GSR with 8, 12, or 16 lincards and verify the performance. Also, could you please clarify what type of GSR LC that you test against?. Cisco has 3 generation of line cards, their OC48/QOC12-POS is able to forward raw data throughput up to 4 Mpps, which I don't think Juniper can accomplish that with fully populated box. - Ihab --- David Wolsefer <[EMAIL PROTECTED]> wrote: > The juniper M20,M40, and M160 are serious routers in > the core IP routing > world because they simply outperform the 12000GSR. > Although I did not test > them against the latest and greatest GSR, we ran > tests with the M40 heads up > against a few older model GSRs.

Re: My impressions of Juniper from the test lab
I've been watching them for awhile now and have been to their new HQ. The M40 can do OC-48 at wire-speed and the m160 can do OC-192 at wire-speed. You can read about all the features, ASICs, etc on their website. I haven't had much opportunitys to get my hands on JunOS however, anyone willing to donate a M20 to my home lab? :) You can read the older JunOS Docs on their website as well, need contract for current release. It's even available in Palm format which is cool. --- David Wolsefer <[EMAIL PROTECTED]> wrote: > The juniper M20,M40, and M160 are serious routers in > the core IP routing > world because they simply outperform the 12000GSR. > Although I did not test > them against the latest and greatest GSR, we ran > tests with the M40 heads up > against a few older model GSRs.

My impressions of Juniper from the test lab
The juniper M20,M40, and M160 are serious routers in the core IP routing world because they simply outperform the 12000GSR. Although I did not test them against the latest and greatest GSR, we ran tests with the M40 heads up against a few older model GSRs. Needless to say, the Juniper is very impressive. We took a smartbits and started loading up the links up to OC-48. The M40 handled the load extremely well at wire speed with no packet loss. The GSR, on the other hand, started dropping packets at about 50% of that load. Does this mean the performance couldn't be improved on the GSR? No, not at all. These GSRs were not tuned at all. They were straight out of the box (so to speak). I think that the bottom line is that we, as engineers, need to be prepared to work with both products. I like Junos and love IOS. You will not get fired for recommending either product. I believe that pricing is competitive for both products as well. Regards, David Wolsefer **NOTE: New CCNA/CCDA List has been formed.
