NetReality Guarantees Services by Application

NetReality Inc. has upgraded its WAN traffic-shaping gear to support quality of service based on application.

The company announced at NetWorld+Interop that new software for its WiseWan equipment lets enterprise managers say which applications get top priority when different applications compete for the same WAN bandwidth.

The WiseWan Accellerator equipment sits between a router and a wide area frame relay or dedicated link.

The new software can recognize 350 separate IP applications and 150 IPX applications. Customers can set rules for each application based on time of day, the server being contacted, what desktop or range of IP address traffic is originating from, what virtual circuit is being accessed, among others. If the traffic is frame relay, less important traffic can be marked as discard eligible in times of congestion to allow buffering of more important traffic.

Traffic is assigned to different traffic queues, with less critical applications assigned to slower queues.

So, for example, IP voice traffic could be given top priority for up to 160K bit/sec at a time - enough to handle 10 simultaneous compressed IP voice calls. The 11th call would not be guaranteed bandwidth.

The upgraded software comes standard with new WiseWan hardware. Current WiseWan customers with a service contract get the upgrade as part of that agreement.

Service providers can use the same new software to offer service-level agreements per application. A service provider would install a WiseWan box at each customer site and could manage it and set policies remotely for the customer. The service provider version of the software does not offer as many options as the enterprise version because service providers lack the time and personnel to set more than a few parameters for their customers.

The service provider software was developed for Swedish carrier Telia.

NetReality's 1Xplorer management software enables customers to monitor their traffic via secure Web links when WiseWan is used to support a managed service.

Data gathered by WiseWan can be integrated with Hewlett-Packard's OpenView, Concord and CiscoWorks software to analyze traffic
