Juniper is set to release a range of WAN application acceleration appliances that it claims will deliver more performance for the money than earlier models.

The WXC 1800, 2600 and 3400 appliances have been designed to deliver consistent application response across the WAN, providing more LAN-like experience for branch office users accessing centralised applications. The devices compete with Cisco's Wide Area Application Services (WAAS) systems, Riverbed's wide area data services (WDS) products, and devices from Blue Coat, Ipanema and others.

Juniper's new hardware delivers higher disk capacities and performance in a smaller form factor than existing WXC appliances, said the company.

The appliances allow businesses to accelerate high volumes of traffic across a range of applications,, including TCP, UDP, MAPI, CIFS and HTTP/S. They deliver functionality such as QoS, content distribution and policy-based multipath along with an integrated configuration, monitoring and troubleshooting application, claimed the company.

The WXC platforms recognise and eliminate redundant transmissions, accelerate TCP and application-specific protocols, prioritise and allocate access to bandwidth and help ensure high application availability at sites with multiple WAN links.

According to Juniper, the on-board hard drives provide support for Network Sequence Caching, which enables the devices to store repeated data patterns, and can produce as much as a 100-fold increase in effective WAN capacity.

The company said that the WXC 1800 could accelerate WAN traffic up to 2Mbit/s, typically at small to medium branch offices. The WXC 2600, designed for use at medium to large branch offices and small data centres, can accelerate traffic up to 8Mbit/s, and the 3400, for use at remote locations, head offices or data centres that require higher speeds, can speed WAN traffic up to 45 Mbit/s.
