Description of Working Group:
The Open Pluggable Edge Service (OPES) working group primary task is to 
define a protocol to be used to extend participating transit intermediaries 
to incorporate services executed on application data transported by HTTP 
and possibly RTP, RTSP.  The protocol provides a framework for integrating 
a wide range of services into arbitrary intermediaries. Intermediaries may 
employ either local or remote ("callout") servers to perform a service, and 
as a result, the data may be diverted temporarily over a closed loop 
pathway different from the transit pathway.
Intermediary services provided in this way are not transparent: Either the 
content requestor or provider will be aware that a transformation has been 
performed.
As part of the development of this protocol the working group will produce 
an analysis of the security implications of this architecture.
A secondary task for this working group is to enumerate the requirements 
for management policies and associated administrative protocols that allow 
these services to be specified and deployed. This includes requirements on 
the rule systems used the define these policies and protocols.
The advantage of standardizing a protocol for this is that services can be 
re-used across vendor products without modifying the transit intermediaries 
or services.
The iCAP protocol already provides similar functionality and this working 
group may elect to use iCAP as a starting point for its work. However, the 
working group is not obliged to retain any level of compatibility with iCAP.
