WAN optimization technology makes waves at Interop New York

By Ann Bednarz

WAN 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:

Executive Guide:Virtualization Meets Reality

Virtualization is being used to make the most out of everything from applications and servers to desktops and storage. But as companies expand their reliance on the technology, challenges mount. Read this guide authored by a host of Network World editors and review this timely topic.

* Riverbed tunes devices for disaster recovery jobs
New software and hardware upgrades from Riverbed are aimed at enterprises that need to replicate large data loads between data centers (as opposed to between a branch office and data center). On the software side, Riverbed unveiled a new version of its RiOS software that includes features tailored for disaster recovery. For example, RiOS 4.1 can analyze the size and type of data to be transferred and tailor its acceleration techniques when it recognizes disaster recovery operations, such as data replication and backup jobs. On the hardware front, Riverbed announced a new Steelhead appliance geared for large-scale data transfers. With a raw capacity of seven terabytes and a three terabyte data store, the Steelhead appliance model 6120 has more than double the storage of previous Steelheads.

* Coyote Point bolsters SMB offerings
Coyote Point Systems unveiled new software for its Equalizer Series load balancing and acceleration appliances, which are designed to appeal in price and user-friendliness to small and midsize businesses, in particular. New features in Equalizer Series V8.0 include: availability improvements such as surge protection for servers and clusters, downed-server alerts, and software diagnosis capabilities; HTTP compression via Coyote Point’s Express HTTP content compression card, which is said to speed downloads fivefold; SSL encryption, offloading and acceleration via the XCEL II SSL accelerator card for Coyote Point’s x50si systems; greater support for Microsoft Outlook Web Access; and improved Web performance management via compatibility with Akamai-powered content distribution networks. The products also feature a revamped GUI, support for fine-grained permissions and new tools for configuring complex routing rules -- all aimed at making it easier for IT administrators to install, configure and maintain Equalizer systems.

* Avistar demos hosted videoconferencing service
Want employees to be able to make desktop videoconferencing calls without bringing the corporate network to its knees? Avistar Communications is positioning its new Hosted Video Services as an option for enterprises in need of a fast way to deploy desktop video communications and data sharing without having to install on-site video infrastructure. The subscription-based service includes bandwidth management and call routing capabilities to ensure that video traffic doesn’t impact other networked applications, Avistar says. For network connectivity, companies can link to an Avistar hosting center using a private line that supports encryption; an encrypted VPN tunnel over a partner IP network; or a company’s existing Internet connection combined with an Avistar-managed VPN gateway at the customer site.

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.
