Client/server HTTP/CCN gateway in CCN environment with cooperative caching
CCN client / CCN server + IP client/IP server/CCN tunelling
1. Motivation
File
HTTP
• Experiment with caching schemes using real traffic server
(HTTP dominates) IP
• Hands-on on application level => universal HTTP/CCN Server
gateway (able to operate in different settings:
inbound/outbound proxy, HTTP tunelling)
2. Naming and mapping of messages Registered names
Requirements
• 100% HTTP compatibility CCN
• easy to implement CCN
• future-proof to the changes of CCNx protocol HTTP
client
Two basic rules adopted:
• Request header – mapped onto content name using
command markers IP IP
• Entity Body always conveyed in Data packets
(sequences of Interest/Data may be required) HTTP
client
Examples:
GET
ccnx://http/<request_method_name>/<URL>/<abs_path>...
.../%C1.http.<header_field_name>~Eb64(field_value)/%C1.http... 4. Actual setup
