Swan Revamps WAN/WAFS Kit

Swan Labs Corp. has taken the next step in its evolution -- and upped the ante against a key rival (see Swan Labs Improves Appliance).

Swan Labs has revamped its WAN optimization appliance, releasing WANJet, a replacement for its Netcelera device introduced late in 2004. WANJet substantially improves Netcelera's application throughput on IP networks. For instance, the vendor claims the addition of new data reduction techniques improves file transfers by 500 times normal throughput, compared with 10 times normal throughput claimed for the older Netcelera product. WANJet also features encryption and a set of application programming interfaces (APIs) for third-party use.

The announcement pits Swan Labs more closely against the likes of Riverbed Technology Inc., which announced a new version of its Steelhead optimization appliance last week (see Riverbed Fords WAN/WAFS Divide). Both companies are part of a trend toward combining the bandwidth-scrunching features of WAN optimizers with the ability to eliminate chattiness characteristic of wide-area file services (WAFS) applications on IP networks (see Remote Site Rapprochement).

Riverbed is ahead of Swan Labs at this point in terms of customers, claiming 200 to Swan Labs' 80.
Yet features of the two firms' devices are strikingly similar: Both support data reduction and TCP optimization. Both work with line speeds up to 622 Mbit/s (OC12). And both now offer encryption, though Swan Labs' is based on SSL and Riverbed's on IPSec.

There are differences. Swan Labs' emphasis on its API reflects its focus on what VP of marketing Tom Tansy calls "cherry-picked partnerships." IBM Corp. (NYSE: IBM) has adapted its technology for Web acceleration, as part of the IBM WebSphere product series. Plumtree Software Inc., which makes Web-based application portals, also OEMs Swan Labs.
