Network OptimizationThis newsletter is sponsored by SymantecNetwork World's Network Optimization Newsletter, 10/25/07WAN optimization technology makes waves at Interop New YorkBy Ann BednarzWAN optimization players flocked to the East Coast this week for Interop New York, which wraps up Friday. Executives from companies including Blue Coat Systems, Cisco, Exinda Networks, Expand Networks, Ipanema Technologies, Packeteer, Riverbed Technology and Strangeloop Networks took part in the conference, sharing insights about emerging technologies and strategies for improving application performance over the wide area. The exposition floor at Interop New York -- which is about half the size of the flagship Las Vegas version of Interop -- also provided a backdrop for a slew of product unveilings. Here are some of the highlights:
* Riverbed tunes devices for disaster recovery jobs * Coyote Point bolsters SMB offerings * Avistar demos hosted videoconferencing service In the next newsletter I’ll cover another vendor that made headlines from Interop New York: Juniper Networks, which upgraded the security and management features in its WX and WXC application acceleration platforms.

Riverbed vs Cisco
Cisco WAAS has a way to go in my opinion.
Here are a handful of key reasons why I feel Riverbed beats Cisco.
Speed
• Cisco only has CIFS application-specific optimization (what about MAPI, HTTP, SSL, NFS, SQL, Oracle?)
• Cisco has separate ‘TCP’ optimization and ‘CIFS’ caching implementations – muddled approach
Scale
• No large-scale reference deployments – Riverbed has dozens
• Data store is per peer as opposed to universal
• No software client for mobile workers
Simplicity
• Cisco requires 95 steps to set up WAAS; Riverbed = 22
• Cisco network transparency approach can cause routing or troubleshooting problems; and CIFS is not transparent!
• “Integrated” router blade has separate management & setup
Cisco is really a caching device, Riverbed does not cache files, it accelerates apps at the bit level and stores references not the actual file. Caching is not efficient (especially as you scale it in a mesh, MPLS type environment). Caching only addresses files not email, web, and other apps. In a cache, if the file is changed then the file is cold again and has to be resent across WAN. Also, if you rename a file it again is cold and must be resent to the other side even though that data exists on the cache already.
Stick with best of breed. Riverbed Steelhead Appliances
