DESCRIPTION
HTTP/CCN Gateway and Cooperative Caching Demonstrator Dariusz Bursztynowski, Mateusz Dzida, Tomasz Janaszka (Telekomunikacja Polska, Orange Labs Poland), Adam Dubiel (Warsaw University of Technology, Poland), Michal Rowicki (Warsaw University of Technology and Telekomunikacja Polska, Poland)TRANSCRIPT
CCNx Comm. Meeting, Sophia-Antipolis, Sept. 12-13, 2012

1. Motivation
• Experiment with caching schemes using real traffic(HTTP dominates)
• Hands-on on application level => universal HTTP/CCN gateway (able to operate in different settings: inbound/outbound proxy, HTTP tunelling)
2. Naming and mapping of messages
3. Architecture – functional settings
CCN client / IP server
4. Actual setup
• CCN client / IP server
• CCN client / CCN server
Watch the demo for more details

6. Demo use cases

Requirements• 100% HTTP compatibility• easy to implement• future-proof to the changes of CCNx protocol
Two basic rules adopted:• Request header – mapped onto content name using
command markers• Entity Body always conveyed in Data packets
(sequences of Interest/Data may be required)
Examples:
GET
POST
ccnx://http/<request_method_name>/<URL>/<abs_path>....../%C1.http.<header_field_name>~Eb64(field_value)/%C1.http...
Need to upload a file using the POSTmethod
Interest (can I send ?)
name:
name:content: OK
Data [OK] (wait for the Interest that prompts you to specify your request)
Interest (specify your POST request)
Data (well, I’m posting this)
name:
content:
Interest (please, send a server OK response to me)
+ body
Data (here goes the OK to the POST)
name:content: OK
