Tarari Ships New XML Silicon: RAX Content Processor
Tarari Inc, an award-winning acceleration company, announced the immediate
availability of its latest XML Silicon technology -– the RAX Content
Processor, which incorporates the industry's first in silicon implementation
of Random Access XML (RAX). RAX fundamentally changes how XML is utilized, as
it allows complex XML document analysis to be completed in near-zero CPU time
-- it flies through complex XML tasks at 40 to 200 times that achieved by
software-only solutions and can easily process millions of XPaths per second.
Random Access XML (RAX) enables network switch, server, blade and appliance
vendors to create a variety of new applications such as gigabit message
classification and routing, high transaction rate publish and subscribe
systems, advanced SOAP message processing, high performance XML security
firewalls and real-time telecommunications billing solutions.
"Content inspection of XML formatted messages and documents at wire speed is a
vital goal that must be reached to enable commercial-grade, end-to-end XML
transaction processing," said Randy Smerik, president and CEO of Tarari Inc.
"DOM and SAX have each brought great advances to the XML world and now RAX
builds on that to dramatically improve network security, eliminate network
bottlenecks, and deliver completely new, highly efficient XML-based
applications to the marketplace."
Why Is RAX Important?
The most efficient way, up until the present time, to process XML has been to
use one of two programming interfaces: DOM or SAX, but these software-based
approaches simply don't scale. RAX on the other hand utilizes W3C
standards-based XPath queries which are fast becoming the most popular way to
decode and route XML documents. Today's method of parsing using XPaths
involves sequentially processing each XPath query—but this is also way too
slow and compute-intensive to be practical in large-scale solutions. The
Tarari RAX Content Processor eliminates this barrier by enabling the
simultaneous processing of very large groups of XPath queries at over 100
million XPaths per second thus offloads compute-intensive tasks from the main
processor. RAX enables gigabit-level XPath processing -- something
unattainable using software.
The core technology enabling RAX is Tarari's Simultaneous XPath engine which
offers remarkable performance characteristics that place it in a league of its
own:
Simultaneous XPath produces results directly from the input XML document,
whereas DOM or SAX-based systems need to create an in-memory representation of
the document. Simultaneous XPath is vastly faster than any software-based XPath engines
(e.g., Saxon, Xalan, libxml) Simultaneous XPath's performance is insensitive
to the number of XPaths in an evaluation group and the complexity of the XPath
expressions. Simultaneous XPath handles XML namespaces and namespace prefixing on the
fly without pre-scanning and declaration of prefixes. Simultaneous XPath execution time increases linearly with the file size,
without any performance degradation and without memory thrashing.
Tarari, working closely with industry leaders and influencers focused on XML
solutions, is proposing that RAX be accepted as an industry-standard just as
DOM and SAX have garnered many supporters within the W3C community.
"Our new 2400 series products will shake up the Web services security industry
and further strengthen our leadership position," said Glenn Osaka, CEO and
president of Reactivity. "With the first XML firewall to incorporate Tarari's
hardware accelerated RAX Content Processor; we are committed to provide our
customers with the broadest range of options to help them achieve instant and
sustainable XML Web services security."
According to ZapThink, LLC, a Massachusetts-based research firm focused on XML
and Web services, the amount of XML traffic on the Internet is already nearly
equal to the amount of email traffic, and will grow to four times the amount
of email traffic by 2006. To ensure the integrity and security of these
applications, all their XML messages must be thoroughly inspected and analyzed
without significantly impacting network and system performance. Current
generation XML security products will not be able to keep up with these
growing demands without incorporating new technology to break this content
processing bottleneck through acceleration.
