A few weeks back Network World hosted an online forum that discussed the technologies needed - and available today from vendors
- to securely accelerate application traffic across the WAN. One vendor, Blue Coat Systems, chimed into the discussion then,
and this week is announcing it will augment its suite of secure proxy appliances with application acceleration technologies.
According to Blue Coat, security is the key differentiator among application acceleration vendors and customers. In Network
World's online forum, network managers noted the lack of tools to speed encrypted traffic over the wide area. And according to statistics from
Blue Coat, nearly 50% of all corporate Web application traffic is SSL, 70% of all mobile and teleworkers use SSL for secure
application delivery and 68% of Blue Coat customers depend upon externally hosted Web applications.
A second key differentiator is video acceleration, the company says. More and more companies are streaming video and providing
video on-demand for internal and external customers. Company representatives say their new acceleration technologies can address
these two concerns for enterprise IT shops.
Blue Coat's MACH5 (Multiprotocol Accelerated Caching Hierarchy) framework of acceleration technologies will accelerate key
enterprise applications, the company says, including secure Web applications such as SSL traffic. MACH5 incorporates bandwidth
management, protocol optimization, object caching, byte caching and compression technologies into Blue Coat's operating systems,
which is loaded onto appliances.
"We create two separate SSL tunnels to accelerate SSL traffic, one between us and the server and us and the user," says Chris
King, product marketing manager at Blue Coat. "That means we can accelerate SSL without having a certificate at branch locations
and without raising privacy issues about unencrypted traffic crossing the WAN."
The technology Blue Coat acquired with Permeo earlier this year helps with the secure acceleration. The main reason for the deal was the desire to incorporate SSL VPN
technology into Blue Coat's Proxy SG appliance that filters Web traffic in and out of businesses, Blue Coat President and
CEO Brian NeSmith said at the time of the deal.
