Editorial Reviews:
Key Findings:
- XML Proxies are hardware or software solutions that actively listen for XML traffic on the network and either pass it along unmodified or perform some action on the XML content. XML Proxies can operate transparently as an XML "gateway" or as auxiliary applications on the network.
- ZapThink estimates that XML represents less than 2% of all traffic on the enterprise network in 2002; however, this percentage is expected to increase to almost 25% of all LAN network traffic by 2006.
- Current firewall and proxy solutions are inadequate to handle XML traffic. Instead of being simply network protocol-aware, XML Proxies are XML-aware.
- XML Proxies are capable of examining traffic at the content level, and can optionally handle other message types such as HTML or EDI.
- XML Proxies will converge on a single set of functionality for handling corporate-wide XML security, management, routing, transformation, and performance enhancement.
- As XML Proxy solutions become increasingly visible in the corporate IT environment, "established" Network Appliance vendors will enter the market.
- XML Proxies can also allow users to implement XML and Web Services solutions without having to constantly modify those applications to comply with various corporate XML policies.
- The increasing need to gain more value out of the XML documents and traffic on the network will drive adoption of XML Proxy solutions.
