Abstract: Techniques are described that enable local caching of content data within metro transport networks for delivery to subscribers of ISPs that are connected to metro transport networks. Routers within the metro transport network, including an access router, ISP-facing provider edge routers and one or more caching routers, establish an EVPN within the metro transport network. The access router outputs, within the EVPN and to the caching routers, EVPN route advertisements that advertise network address reachability information of the subscriber devices on behalf of the ISPs. Responsive to subscriber content requests that have been redirected from the ISPs and based on the EVPN route advertisements from the access routers, the caching routers of the metro transport network forward, by the EVPN, content from the local content cache to the access routers for efficient delivery to the one or more of the subscribers.

Abstract: A first device may receive information that assigns a function related to network traffic associated with a content delivery network. The first device may implement the function based on the information that assigns the function. The first device may receive the network traffic from the content delivery network and may provide the network traffic to a subscriber device. The first device may provide, to a second device, information associated with the network traffic based on implementing the function. The second device may manage a subscriber session associated with the subscriber device based on the information associated with the network traffic.
