The Extensible Proxy Services Framework has a new website,
www.extproxy.org
A mailing list, subscribable at ietf-openproxy-request@imc.org
and a workshop announcement:
Call for Participation: Workshop on
Sophisticated Content Services for the Network:
Extensible Proxies
September 13, 2000
San Jose Convention Center
San Jose, California
http://www.extproxy.org
This workshop will help to define a new platform for the Internet, one that is essential for engineering the delivery of sophisticated content forms and is also essential for bringing a new level of sophistication to content delivery. We are seeking participants who can bring to bear architectural innovations, new services ideas, and to either inspire or be inspired by a new direction in the evolution of the Internet.
In today's Internet, the infrastructure creating the "the net" is pointing towards a new network service model. The Web is becoming clients or user agents that consume information, content servers that provide the basic information and units of Web infrastructure which are the Proxies (or Proxy-Cache). These critical infrastructure devices provide the opportunity for enhanced services that expand the value of content on the Internet. Examples of such services are:
· content adjustment - adjusting and/or assembling the content ultimately being delivered to the user. Today we see this in content assembly for advertising.
· presentation adjustment - modifying the content presentation to be more suitable for the client. Today we have WAP and other gateways to adjust content.
· semantic management - evaluate content against classification criteria such as virus detection, topic, legality, etc.
Extending the notion of content services leads us to operations such as:
· Data dependent cache functioning - cache management strategy is a function of the nature of the cached data. Content providers are already acting on the requirements for caching streaming multimedia data.
· Web accounting - tracking Web usage independently of the content server or user client. Multiple network sharing - objects obtained from a data network can, for example, feed a broadcast system.
A recent Internet-Draft (http://www.ietf.org/internet-drafts/draft-tomlinson-epsfw-00.txt) proposed an architectural framework for standardizing the components and APIs that can be used to build these services. This is the Extensible Proxy Services Framework. We are holding a working to present and discuss concepts needed for standardizing components in the Proxy system.
Suggested areas for papers or panels are
High-performance architecture requirements and engineering criteria
Innovative services on proxy platforms (e.g. messaging, geographic positioning, etc.)
Languages for extensible services
Dynamic service extensions: delivery, loading, etc.
New communication protocols
Other new platform architectures for Internet infrastructure
Papers and panels must be submitted by August 31, 2000. Please send a title and abstract for papers to condry@eng.sun.com; panel proposals should include title, abstract, and names of committed panelists and should be sent to horman@novell.com. Responses will be sent by September 3, 2000.
Registration information will be available at http://www.extproxy.org
