Generic AAA based provisioning Of Network Elements Status update EVL 9/10/03 Leon Gommans University of Amsterdam

 Generic AAA quick overview  Generic AAA server status & features  Testbed options  Example policy and request message  Discussion on request message format. 9 Oct 2003Update meeting EVL Leon Gommans Update

 AAA server may not be a good name. As it does:  Receive a request message that may contain authorization information + other attributes  Fetch a driving policy and evaluate information contained within the request and take an authorization decision  Take one or more policy actions based on the outcome of the policy decision.  Evaluation of policy may involve other AAA servers. 9 Oct 2003Update meeting EVL Leon Gommans Main functions AAA server

9 Oct 2003Update meeting EVL Leon Gommans Generic AAA Architecture RFC2903 Policy Decision Point Policy Enforcement Point Fundamental idea’s inspired by work of the IETF RAP WG that in RFC 2753 describes a framework for Policy-based Admission Control. Foundation for COPS The point where policy decisions are made. The point where the policy decisions are actually enforced. Request Decision Policy Repository Basic Goal Generic AAA: Allow policy decisions to be made by multiple PDP’s belonging to different administrative domains.

9 Oct 2003Update meeting EVL Leon Gommans Generic AAA Architecture Application Specific Module Policy Enforcement Point Archieve goal by by separating the logical decision process from the application specific parts within the PDP. Request Decision Rule Based Engine Policy Repository PDP

 First implementation RBE and ASM’s was build as servlet on an Apache / Axis webserver environment. Demo’d at iGrid2002.  Converted RBE and ASM to run within a J2EE EJB container (J2EE V1.4 beta2 reference edition)  Needed Java Connector Architecture which became available in 1.4 to communicate to the outside world to talk CLI/TL-1 or SNMP.  Using JCA was major effort (no/bad documentation - non running example code etc.)  J2EE gives us WS features.  Integrated simple OGSA service as test. 9 Oct 2003Update meeting EVL Leon Gommans Generic AAA server Implementation at UvA
