METHOD AND SYSTEM FOR NETWORK ACCESS DISCOVERY

Title:

METHOD AND SYSTEM FOR NETWORK ACCESS DISCOVERY

Document Type and Number:

WIPO Patent Application WO/2019/179319

Kind Code:

A1

Abstract:

Aspects of the disclosure provide a system and method used for receiving Address Resolution Protocol (ARP) requests from access nodes and returning a designated address to satisfy a service provider' policies. This can include receiving a request from an access node at a provider edge node, and returning a designated Media Access Control (MAC) address in response to a request for a MAC address for a specified destination IP address, the designated MAC address being a MAC address for a node other than the provider edge node. This can effectively route requests to a Policy Enforcement point (PEP), which can be, for example a Broadband Services Router (BSR). A network controller can update ARP tables in the provider edge node to ensure that traffic which require policy enforcement can be routed to the PEP, whereas traffic which does not require policy enforcement can be normally routed towards the traffic's destination.
