Pivia Software Speeds Microsoft NT LAN Manager
Pivia Software Inc announced that the Pivia Performance Server (PPS) now
includes optimizations for Web applications that depend on Microsoft's NT LAN
Manager. Pivia's NTLM optimizations improve end-user wide area network (WAN)
and Internet application performance by removing several NTLM bottlenecks that
appear over high latency network connections. Pivia's NTLM optimizations do
not affect application authentication or security quality, and are transparent
to the user and origin application.
Microsoft NTLM is the industry's most commonly used authentication mechanism
for Windows applications, despite the fact that it is highly inefficient when
used over the Internet or a WAN. The NTLM protocol requires multiple
connections to be established and destroyed before the data can be sent to the
user and the protocol utilizes TCP-based sessions as opposed to browser-based
sessions. These NTLM qualities cause application latency, network bottlenecks
and expensive authentication per user.
"Application security is a key requirement for global companies as they scale
mission critical application deployments," said Albert Gouyet, vice president
of marketing at Pivia Software. "But many companies are trading performance
for security when using authentication technologies such as Microsoft NTLM
over the Internet or a WAN. We are committed to offering our customers
technologies that allow companies to preserve high application security
without paying the price of poor application performance."
Pivia's NTLM optimizations closely control browser activity to reduce the
number of browser-to-server authentication requests, thereby reducing network
interactions that can degrade application performance. If appropriate, Pivia
allows multiple browser connections to leverage an exiting NTLM authentication
for the same user, which significantly improves the performance of WAN and
Internet applications.
Key Features
- NTLM Authentication and Connection Sharing -- NTLM connections are
optimized to allow multiple browser connections to share a single origin NTLM
authentication for the same user. This optimization eliminates the overhead of
repeated authentication over multiple connections for the same authenticated
user.
- NTLM Content Caching -- Content is optimized and served directly from the
Pivia Performance Server to authenticated users. This is tremendously
beneficial when transmitting images, javascript and style sheets.
- NTLM Application Optimization -- Web application behavior is adjusted to
become "NTLM friendly" by eliminating operations that require opening and
closing connections to authenticated users.
