Abstract: A method implemented by a source router reduces the number of SPF computations needed to compute TI-LFA backup paths. Rather than naively perform a backup path computation for all destinations, the source router identifies those destinations affected by that link or node failure and performs backup path computations only for the affected destinations. For the remaining destinations (i.e., those for which a backup path is required), the backup path computations are performed in a breath-first order relative to a subtree rooted at the node incident to the failed link (in the case of a link failure) or at the protected node (in the case of a node failure). The breath-first order further reduces the number of computations required by taking advantage of earlier backup path computations.

Abstract: According to certain non-limiting embodiments disclosed herein, the functionality of a distributed computing platform, such as a content delivery network with network storage, is improved by providing automated and on-demand upload capability into the network storage. In one embodiment, the platform is made up of many proxy servers. As clients request content from the proxies, they generate upload commands for the network storage subsystem to ingest the content from a content provider origin infrastructure. Preferably, the proxy servers are configured to generate ‘safe’ upload commands such that objects are not ingested if they contain sensitive information and/or are personalized and/or might be dynamically generated objects. Thus, relatively safe ‘static’ objects can be automatically uploaded and migrated from a content provider origin, as client requests arrive.

Abstract: A load balancer receives a sequence of requests for computing service and distributes the requests for computing service to a computing node in an ordered list of computing nodes until the computing node reaches its maximum allowable compute capability. Responsive to an indication that the computing node has reached its maximum allowable compute capability, the load balancer distributes subsequent requests for computing service to another computing node in the ordered list. If the computing node is the last computing node in the ordered list, the load balancer distributes a subsequent request for computing service to a computing node other than one of the computing nodes in the ordered list of computing nodes. If the computing node is not the last computing node in the ordered list, the load balancer distributes a subsequent request for computing service to another computing node in the ordered list of computing nodes.

Abstract: A digital magazine application executing on a client device presents digital content to a user. Historical connectivity data describing connectivity between the client device and a network is obtained and is used to determine a predicted disconnection time indicating an anticipated loss of connectivity between the client device and the network. The historical connectivity is also used to determine a preload time prior to the predicted disconnection time.

Content may be selected for transmission based on attributes of content previously requested when the connection between the client device and network has less than a threshold bandwidth. At the preload time, for example, the client device requests a section of a digital magazine associated with content previously requested at times of low-bandwidth network connectivity.

The first request indicates the ingress node, egress node, network constraint, and scheduled time interval having a predetermined start time and a predetermined end time for the temporal LSP to carry traffic. The ingress node computes a shortest path in the network for the temporal LSP that satisfies the network constraint in a shifted time interval when the request indicates that the time interval is elastic, and reserves a network resource for use during the shifted time interval for the temporal LSP in advance of the predetermined start time on a link extending from the ingress node to a next hop node on the path. The ingress node sends a path message to the next hop node to set up the temporal LSP in the shifted time interval.

Abstract: A content delivery network (CDN) typically includes a mapping system for directing requests to CDN servers. One or more peer machines become associated with the CDN, and the CDN mapping system is then used to enable a given peer to locate another peer in the P2P network, and/or a CDN server. Using this hybrid approach, CDN customer content may be delivered from the CDN edge network, from the P2P network, or from both networks. In one embodiment, customer content is uploaded to the CDN and stored in the edge network, or in a storage network associated therewith. The CDN edge network is then used to prime the P2P network, which may be used to take over some of the content delivery requirements for the customer content. The decision of whether to use edge network or peer network resources for delivery may be based on load and traffic conditions.
