Routing Performance

Ad

Testing Notes:
• All tests are all run with LAN endpoint in DMZ

Routing performance was extremely impressive and shows the punch that the newer Broadcom processor packs. The chart and Figure 13 show for all intents and purposes wire-speed routing, which I've seen on only the ASUS SL-1000 and USR 8200. These products use the Philips PTD2210 Gateway-on-a-chip and Intel IXP422 network processor respectively.

Since throughput was so speedy, I thought I'd check to see how good UDP streaming was and ran tests using a 1Mbps stream rate in addition to my usual 500 kbps. The results showed that the WZR was still going strong at the higher streaming rate with results in both directions losing only a few Kbps and an occasional error rate in the 0 - 1% range. Impressive!
