Introduction Project’s Goal Software Design Implementation and Testing Creating configuration platform for the GFE system Software Design Implementation and Testing Communication Protocols – VLAN Local and Remote GFE Control Panel

What’s GFE ? General Forwarding Element Generic and flexible: Forwarding, Processing, Multicast, Encapsulation/De-capsulation, QoS and more. XML based API Based on Logical Functional Blocks (LFBs) GFE Control Panel

What’s the Problem GFE Programming is currently done using: Native API Supported programming protocol (e.g., ForCES and OpenFlow) Inconvenient for developers Generic and Dynamic approach GFE Control Panel

GFE Control Panel Interface

General Command line style Commands are actually Scripts – Generic configuration Commands are organized in hierarchically ordered, technology oriented, categories Categories and their respective commands are loaded on initialization – not hard coded Enables remote operation GFE Control Panel

GFE CP Interface Features Command line style Interface GFE Control Panel

GFE CP Interface Features Using scripts for editing the LFB definitions GFE Control Panel

Scripts Manual Signature Command Lines GFE Control Panel

Scripts A script has 3 parts: Manual header ( “//” ) Signature line : procedure ReturnValue = CommandName( arg1, arg2 ) Arguments are passed by order, as in programming function. Script command lines GFE Control Panel

Scripts Structure Variables Functions “Voids” Loops GFE Control Panel

GFE Control Panel The Interface can work either locally or remotely In order to remotely access the GFE, a Web Services bundle has been created GFE Control Panel

GFE Control Panel Web Service

GFE Web Service Enabling remote operation Stand Alone component Including a Client-side module and a Server-side application SOAP Approach GFE Control Panel

Web Service Architecture Client Server GFE System Client Program GFE Web Service GFE Tables GFE Control Panel

GFE Web Service API XML XML XML Client Server XML Classifier Web Server GFE Handle LFB Load XML Forwarder GFE Tables XML Mapper GFE Control Panel

Future Work Finalizing the GFE Control Panel Interface and Web Service as a product Adding functionality to scripting, as required by complex protocols, to be tested with the GFE system Creating other configuration programs, such as web based interfaces, using the GFE Web Service GFE Control Panel
