  • Patent number: 10630771
    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.

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.

  • Patent number: 9813284
    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.

  • Patent number: 9209981
    Abstract: Power Sourcing Equipment (PSE) provides a PoE supply voltage over data wires to a Powered Device (PD). A PSE controller controls a first FET that couples the PoE voltage to the data wire pairs and controls a second FET that couples the data wire pairs to the spare wire pairs. Upon powering up, the PSE controller keeps the two FETs open and performs a detection routine on any devices connected to the data pairs and spare pairs. If a PoE-compatible PD is detected as being coupled to the data pairs, the first switch is closed. If it is determined that the PoE voltage should also be coupled to the spare pairs, the second FET is also closed. The method prevents the PoE voltage from being applied to the spare pairs when the device connected to the spare pairs is not PoE compatible and maintains backwards compliance with IEEE PoE PDs.

  • Patent number: 9203736
    Abstract: Techniques for providing resilient multicast traffic processing in a network element are described herein. In one embodiment of the invention, a network element separately joins equivalent multicast traffic streams at a first and second interface respectively. During uninterrupted operation, the network element processes the packets of the multicast traffic stream it receives at the first interface and drops the packets of the equivalent multicast traffic stream it receives at the second interface. Upon an interruption of the packets of the multicast traffic stream being received at the first interface, the network element transitions to processing the packets of the equivalent multicast traffic stream it receives at the second interface. Other methods and apparatuses are also described.
