METHOD AND SYSTEM FOR EXTENDING NETWORK RESOURCES CAMPUS-WIDE BASED ON USER ROLE AND LOCATION

摘要

A method, system, and computer readable medium is disclosed which utilizes the LISP control plane to increase communications and access to enterprise resources in a network with multiple subnetworks, such as a university setting. As a result, the various embodiments of the present invention provide a routing and services dimension to enterprise discovery protocol traffic, such as Apple Bonjour traffic. A LISP instance ID, which is carried in the LISP header, is used to associate one or more end user devices with specific enterprise resources in a particular subnetwork or a service domain, wherein these resources may be accessed by the end user device even if the end user device migrates to another subnetwork. Another embodiment of the invention limits routing services advertisements from enterprise services to a subset of end user devices associated with particular user EIDs by using L2-LISP multicast techniques.

主权项

1. A method of providing an end user device associated with a user end point ID (“user EID”) in a first subnetwork access to one or more enterprise services in a second subnetwork, the method comprising:
determining associated LISP instance IDs for the user EID, wherein a LISP instance ID is associated with the one or more enterprise services; fetching identification information for the one or more enterprise services from a LISP map server; sending a service group join request on behalf of the user EID to the one or more enterprise services based on the identification information; and, allowing the end user device in the first subnetwork to access an enterprise service regardless of the end host or enterprise service location.
