Abstract
Apparatus and methods for managing content delivery in a packetized network. The network provide content to a plurality of clients via a plurality of nodes. A security threat associated with one of the nodes is detected and in response the host uses border gateway protocol to communicate non-forwarding table information informing one or more nodes of the network of the threat. In another variant, communication allows the nodes to take local action to protect themselves. This same local action occurs on the host, allowing it to continue serving content. The host utilizes BGP to dynamically inform nodes of changes in the network traffic delivery rules, such as causing traffic to different clients having different levels of reliability and/or provided on a best-effort basis. The BGP may be utilized to add/remove routes or nodes and to identify and respond to potentially malicious activities, changes in network configuration, and/or delivery requirements.
