Expand Launches ``Instant QoS'' Capabilities; QoS Finds ROI When Combined With Expanded WAN Capacity From Accelerators.

Business Editors/High-Tech Writers


Expand Networks, a leader in bandwidth optimization technology, today announced the availability of Instant QoS, a new simple-to-use WAN Quality of Service software module available in its ACCELERATOR product line. The new module makes the ACCELERATORs the first product in the market that combines WAN expansion capabilities with end-to-end QoS capabilities.

The new module responds to the growing need for a simple-to-use, yet robust solution that increases the overall size of the wide area pipe while dividing the pipe into priority segments. Instant QoS leverages the existence of ACCELERATORs at both ends of a link to provide end-to-end enforcement of prioritization policies.

Instant QoS relies on three of the following mechanisms:
-- Congestion control is provided through an easy-to-use series of user interfaces to rapidly prioritize applications and control packet flow at peak utilization.

-- Real-time congestion avoidance performed by intelligent self-learning algorithms and proactive packet loss recovery instantly eliminates surges of WAN application traffic.

-- Early congestion detection is carried out by automatic network and application monitoring at both ends of the link in conjunction with the recently introduced Expand AppView module.

"Network QoS only makes sense in the context of the business objectives and priorities of the customer, especially in today's economic conditions," said Peter Christy chris·ty  
Variant of christie.
, co-founder of NetsEdge Research. "Expand's Instant QoS economic justification is straightforward first because it is a software-add-in module to an existing product, and even more so because of the end-to-end, traffic sensitive design and simple end-user configuration tools that make the business priorities of network traffic explicit."

Key features and capabilities of Expand's Instant QoS include:

-- Uniquely economical -- By instantly applying prioritization

policies to the expanded WAN bandwidth, Expand Instant QoS

represents a uniquely economical application performance solution.

-- Instant prioritization -- Out-of-the-box policy templates using

easy-to-understand terms such as "real-time," "mission-critical,"

"important," and "best effort."

-- End-to-end flow control -- Monitoring at both ends of the link

enables accurate end-to-end flow control.

-- Full QoS control -- Predictable results with standard queuing

mechanisms -- FIFO (First In First Out) A storage method that retrieves the item stored for the longest time. Contrast with LIFO. See traffic engineering methods.

"Instant QoS will deliver a lot of value to businesses like ours," said Morey Straus, Network Manager for GeoLogistics Corporation.

"Our VARs are constantly challenging Expand to add more 'intelligence' into its WAN bandwidth optimization solutions," said Jamie Jalazo, vice president, of Sales and Marketing at Alternative Technology. "Therefore it comes as no surprise that many VARs and end-users have already expressed a keen interest in Expand's Instant QoS."

"ACCELERATORs are being increasingly adopted by the highly distributed enterprises in the retail, logistics and financial communities," said Talmon Marco, president and co-founder, Expand Networks. "Instant QoS responds to customer requests for an overall increase in WAN capacity with the flexibility to prioritize point-of-sale applications, CRM systems and financial transactions."

Expand Instant QoS is immediately available through Expand's worldwide distribution, reseller, service provider and strategic partner channels.

About Expand Networks

Expand Networks pioneered the development of bandwidth boosting appliances -- the ACCELERATORs -- which increase network capacity by 100 -400+%. The ACCELERATORs eliminate the need for costly WAN link upgrades, enabling quicker deployments of new applications to remote offices. Networked applications such as CRM, e-mail, ERP (Enterprise Resource Planning) An integrated information system that serves all departments within an enterprise. Evolving out of the manufacturing industry, ERP implies the use of packaged software rather than proprietary software written by or for one customer. , Thin Client and XML XML

 increase the strain on scarce WAN resources, often hindering productivity. By removing repeat data patterns found in any type of traffic, the ACCELERATORs provide important bandwidth savings. The end-result is the decrease in network congestion In data networking and queueing theory, network congestion occurs when a link or node is carrying so much data that its quality of service deteriorates. Typical effects include queueing delay, packet loss or the blocking of new connections. , which in turn speeds up data transfers. Expand Networks allows enterprises to support more networked users, applications and services with fewer resources delivering a typical ROI (Return On Investment) The monetary benefits derived from having spent money on developing or revising a system.
