Abstract: A system includes a plurality of cache servers and a domain name server. Each of the cache servers is configured to respond to a content request. The plurality of cache servers is divided into a plurality of subsets and configured to respond to an anycast address for each subset to which the cache server belongs. The domain name server is configured to receive a request from a requestor for a cache server address, identify an anycast address for a largest available subset, and provide the anycast address of the largest available subset to the requestor.

Abstract: 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.

Abstract: A router may include a central processing unit-based line card storing a forwarding table that includes a first set of entries, a network processing unit-based line card storing a partial forwarding table that includes a second set of entries comprising a subset of the first set of entries, where the second set of entries comprises entries that are most utilized by a plurality of line cards of the router, and a route controller for updating the second set of entries to comprise the entries that are the most utilized. The network processing unit-based line card may forward a packet when an entry in the partial forwarding table matches the packet and may forward the packet to the central processing unit-based line card to forward the packet when there is no entry in the partial forwarding table of the network processing-unit based line card that matches the packet.

Abstract: 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.
Abstract translation: 网络被配置为利用可用带宽进行批量数据传输，而不会基本上影响网络中对时间敏感业务的成功传输。 为了避免这种干扰，承载大量数据传输数据的分组与低优先级类相关联，使得网络的路由器将优先通过与网络的正常业务相关联的分组来丢弃这些分组。 因此，当正常流量峰值或存在链路故障或设备故障时，通常的业务优先通过批量传输业务传输，因此批量传输业务动态地适应网络可用带宽的变化。 此外，为了减少丢弃的分组对于批量传输业务的影响，使用丢失传输协议将批量传输业务的分组编码在源组件或其附近，使得丢弃的分组可以在下游再现 链接。

Abstract: 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.
