| | Reflexive Forwarding for CCNx and NDN Protocols |
| |
|
Current Information-Centric Networking protocols such as CCNx and NDN have a wide range of useful applications in content retrieval and other scenarios that depend only on a robust two-way exchange in the form of a request and response (represented by an _Interest-Data exchange_ in the case of the two protocols noted above). A number of important applications however, require placing large amounts of data in the Interest message, and/or more than one two-way handshake. While these can be accomplished using independent Interest-Data exchanges by reversing the roles of consumer and producer, such approaches can be both clumsy for applications and problematic from a state management, congestion control, or security standpoint. This specification proposes a _Reflexive Forwarding_ extension to the CCNx and NDN protocol architectures that eliminates the problems inherent in using independent Interest-Data exchanges for such applications. It updates RFC8569 and RFC8609. |
| | CCNx Content Object Chunking |
| |
|
This document specifies a chunking protocol for dividing a user payload into CCNx Content Objects. It defines a name segment type to identify each sequential chunk number and a Content Object field to identify the last available chunk number. This includes specification for the naming convention to use for the chunked payload and a field added to a Content Object to represent the last chunk of an object. This document updates RFC8569 and RFC8609. |
| | CCNx Content Versioning |
| |
|
This document defines a method for content versioning in CCNx, enabling the differentiation of content sharing the same name using version numbers. This document updates RFC8569 [RFC8569] and RFC8609 [RFC8609]. |
