Method and apparatus for scalable content routing and mobility in named data networks

摘要

Various disclosed embodiments include methods, systems, and computer-readable media for named data network (NDN) inter/intra-domain mobility. A complete de-coupling of identity and addressing space is established. This provides separation of control and forwarding allowing rich policy based routing, using SDN principles, as well as policy based global resolution. In one embodiment, the de-coupling of identity from location is achieved by a changeable forwarding label field in a header that can have nodal/domain/global scope. This disclosure provides content routing/mobility to be handled with a high degree of flexibility. This disclosure also provides mobility as a service for a component of a name space.

主权项

1. A system configured for routing a message in a named data network (NDN), comprising:
a first service router configured to receive a registration message from a producer node and send the registration message to a domain controller for registering the producer node, wherein the producer node provides content; and a second service router configured to: receive an interest message from a consumer node, wherein the interest message indicates interest for the content, and a header of the interest message includes a name of the content, obtain a first forwarding label according to the name of the content, wherein the first forwarding label indicates an address associated with a location of the content; and send an updated interest message to a next hop node in the NDN network, wherein a header of the updated interest message includes a first field containing the name of the content and a second field containing the first forwarding label, and wherein the first field and the second field are two separate fields.
