Title:
COLLABORATIVE IN-NETWORK NAME-TO-LOCATOR RESOLUTION SUPPORT FOR INFORMATION CENTRIC NETWORKING
Document Type and Number:
WIPO Patent Application WO/2020/107768
Kind Code:
A1
Abstract:
Methodologies and architectures are provided for performing localized name-to-locator resolution in an Information Centric Network (ICN) network. In various embodiments, each edge router of a plurality of the edge routers of the network are assigned a subset of a managed namespace. Each of the edge routers maintains a resolution cache for storing namespace-to-locator mapping information, the resolution cache including a long-term cache for storing mapping information relating to the subset of the namespace, and a short-term cache for storing mapping information relating to non-assigned namespace. When receiving an interest packet including a content name corresponding to a non-assigned namespace, an edge router determines whether corresponding mapping information is included within the short-term cache of the edge router. If not, an appropriate resolution identifier is set and the interest packet is forwarded to a second edge router for processing (e.g., a router assigned to the namespace corresponding to the content name).
