摘要: A content distribution network includes a first server in communication with an anycast server that provides content via a unicast signal, and with a multicast server that provides the content via a multicast signal. The first server is configured to receive a list of source addresses associated with the content, and to provide a metadata file including an anycast Internet protocol address of the anycast server from the list of source addresses as an Internet protocol address of the content in response to a first request for the content. When the number of client devices requesting the content exceeds a first threshold, the first server receives an updated list of sources including a multicast Internet protocol address of a multicast server, and provides the multicast Internet protocol address of the multicast server as the Internet protocol address of the content in the metadata file.

摘要: Concepts and technologies are disclosed herein for management of forwarding tables at edge routers. A processor that executes a software defined networking controller can select an edge router associated with a networking environment. The edge router can access or use a forwarding table. The processor can obtain routing information associated with the edge router. The routing information can include forwarding table contents associated with the forwarding table and next hop information that can indicate communication paths associated with the edge router. The processor can analyze the routing information to determine next hops associated with the edge router, generate a next hop graph that represents the next hops, and initiate updating of the forwarding table such that the forwarding table only includes data that corresponds to the next hops.

摘要: A content distribution network includes first and second controllers, and multicast enabled routers. The first controller is configured to select a multicast channel for distributing content, to determine that the content has a geographic restriction associated with a restricted area in the content distribution network, to link an exclusion policy for the content to the multicast channel while the multicast channel provides the content, and to deny a request for the content from a client system within the restricted area based on the exclusion policy. The second controller is configured to distribute the exclusion policy to the multicast enabled routers including a first router configured to store the exclusion policy, and to ignore a multicast join message from the client system within the restricted area based on the exclusion policy.

摘要: A network is configured to utilize available bandwidth to conduct bulk data transfers without substantially affecting the successful transmission of time-sensitive traffic in the network. In order to avoid this interference, the packets carrying data for bulk data transfers are associated with a low priority class such that the routers of the network will preferentially drop these packets over packets associated with the normal traffic of the network. As such, when the normal traffic peaks or there are link failures or equipment failures, the normal traffic is preferentially transmitted over the bulk-transfer traffic and thus the bulk-transfer traffic dynamically adapts to changes in the available bandwidth of the network. Further, to reduce the impact of dropped packets for the bulk-transfer traffic, the packets of the bulk-transfer traffic are encoded at or near the source component using a loss-resistant transport protocol so that the dropped packets can be reproduced at a downstream link.

摘要: Concepts and technologies are disclosed herein for providing and using a software defined network controller. A software defined network controller can be provided by a computing system that includes a processor. A service model that represents a service can be obtained. A network model that represents network resources that support the service can be obtained. Resources that support the service can be determined. Templates can be accessed to identify templates that relate to the resources. The templates identified can be assembled to obtain a template-based representation of the service. The template-based representation can be executed to determine if the service is ready for deployment.
