The End of the Open Internet?: Network Service and Security in Web 2.0

How does the huge political movement connects with thye small world of Informatic Systems? The Internet is evolving toward a more managed model. Sore are predicationg the end of the "Open Internet". XML Open Data enables many of those changes. We have an almost "Layer 8" in the Network stack, with an higher lever of abstaction, value-added Application Network Services, and issues like Security or QoS.

Layer 8: On top of the Application layer, nowadays we have a "Services" layer, not exclusively on top of HTTP...

Application Networling: Networking vendors have to address XML Open Data but they to address XML Open Data but theyt can also enlarge their market doing it... An example of this is "Cisco AON", that gives Content-Based Routing, Web Services Security, XTM XML Threat Management (Layer 8 firewall), App-to-App Mediation (usually XSLT), Application Acceleration (compression, caching, validation), Com pliance Enforcement, Business Inteligence Capture and Network Utilization Monitoring.

Security: The Internet is utterly broken, security-wise. Related to Open Data, you can do Deep Content Inspection and consider that all packets are NOT equal. I just knew about "Attribute Explosion", a known method of breaking an webservice...

QoS: Patches like MPLS are band-aids, not sollutions. Transport, open data provides nice means to implement QoS methods.

Examples on how to implement Open Data stuff into the network layer: XML Content-Based Routing can be done. For instance, with XPATH you can decide the priority of Service packages.

Application Networking and Pay for Performance: While the "carriers" (telcos, owner of the "big pipes") want to charge for performance-level based access to the network, Cisco (and others) have the first stage of technology to provice Open Data (XML-based) Application QoS in the network, that, while it isn't yet integrated into router, it will be.

So, is the Open Internet going to end? Who will win the political fight about who "owns" the internet?
