摘要： Implementations described and claimed herein provide a system and methods for dynamic re-localization and manifest chunking in a content delivery network. In one implementation, one or more stimuli corresponding to a connection to deliver content from a content source over a network to a user device along a network path are detected. The one or more stimuli indicate a connection issue. An optimized network path through which to deliver the content to the user device is determined based on current network conditions. The optimized network path responds to the connection issue. The user device is dynamically rerouted to the optimized path while providing a substantially continuous delivery of content to the user device.

摘要： An apparatus is provided for control of a plurality of forwarding switches using a network controller. The network controller executes a routing configuration application that analyzes interconnections between the forwarding switches to identify a topology of the network, determine label switched paths (LSPs) between the forwarding switches, and transmits the next hop routes to the forwarding switches. The forwarding switches use the next hop routes to route packets through the network according to a multiprotocol label switching (MPLS) protocol. Each LSP includes one or more next hop routes defining a forwarding address associated with one forwarding switch to an adjacent forwarding switch.
