The article reports that increase in the XML and Web services traffic will boost the content-aware networking. Under its Application-Oriented Network product strategy Cisco Systems Inc. plans to offer content-filtering blades that can be configured into its routers and switches. Driven by policy, network appliances can take very specific actions to achieve very specific results. Cast Iron Systems and Solace Systems specialize in content-aware application data routing, whereas, others such as ActivNetworks, focus on compression, caching and other application acceleration functions. In the present scenario it seems that the pace of merger, acquisition and partnering activity will remain vigorous and the functional distinctions between content-aware network appliances and traditional Layer 2-4 devices will continue to blur, as vendors increasingly tout routers, load balancers, firewalls and other products that operate across many service layers. However the content-aware network appliances will only supplement, not replace the traditional routers, load balancers, firewalls and other traffic-control nodes.
