CacheMule: A mobile-carried content location mechanism

摘要

We consider the abstractions that are required in an information centric network. The usual publish and subscribe primitives need to be extended with some content location additions. Indeed, one of the main challenges of information centric networks is to keep the content routing consistent, and this would be eased by offering content location support in the protocol to get and push data. The two primitives we suggest are a content location message that requests not the content, but its availability, and a content hint message that lets the consumer specifies where to find the content to the network. Both are needed to cope with the uncertainty of the content location that comes from the huge scale and the highly dynamic nature of content routing tables.
