Repo protocol and repo-ng¶

Repo protocol¶

Repo protocol is semantics and operating process for persistent storage node in NDN. The operation of NDN repo includes reading from, insertion to and deleting from data objects in NDN repository nodes.

Repo protocol is based on Command Interests specification.

Repo protocol conforms to protocols and specifications for operating and controlling.

• NFD command interests for constructing signed interest of access control.
• Repo Protocol Specification
• NFD Control Command specification: The reponse of insertion and deletion command will follow the response format of this specification, but with different defination of status code.

repo-ng¶

repo-ng (repo-new generation) is an implementation of NDN persistent in-network storage conforming to Repo protocol. It uses ndn-cpp-dev as NDN client library and database sqlite3 as underlying data storage.

platform and libraries¶

• C++ 03, code style guidelines
• Boost >=1.48.0, we use |a limited set of Boost libraries
• Boost Unit Test Framework, more information on [unit testing
• ndn-cpp-dev, Extended version of NDN C++ client library
• waf build system
• sqlite3

specific design¶

• Database design
• Software Structure

current supported functions¶

Most parts of the protocol are supported in repo-ng. The following specifications are not supported in current version.
