  • Patent number: 11641389
    Abstract: A method of delivering content comprises, at a node in a network, receiving a first request to access a first webpage from a client computer, and after establishing a session with the client computer, transmitting a second request to a server in the network. The method further comprises receiving a first file for rendering the first webpage, extracting one or more hyperlinks to one or more second webpages from the first file, prefetching one or more second files for rendering respective ones of the one or more second webpages, and storing the one or more second files in a session cache associated with the session. The method further comprises receiving a third request to access a third webpage from the client computer; retrieving a third file for rendering the third webpage from the session cache in response to determination that the one or more second files include the third file; and transmitting the third file to the client computer.

  • Patent number: 11581981
    Abstract: Exemplary methods, apparatuses, and systems include duplicating a packet within a plurality of packets to be transmitted to a destination computing node as a sequence of packets. The plurality of packets including the duplicate of the packet are transmitted to the destination computing node. Upon receiving a first acknowledgement of the packet from the destination computing node, it is determined that the first acknowledgment is directed to a duplicated packet. In response to determining that the first acknowledgment is directed to a duplicated packet, it is determined that a second acknowledgement has yet to be received for each of one or more packets within the plurality of packets transmitted prior to the packet. In response to determining that the second acknowledgement has yet to be received, the one or more packets are retransmitted to the destination computing node.

  • Patent number: 11553060
    Abstract: A system and method are provided for provisioning code snippets for programming a content delivery network. The method includes receiving a first client code snippet from a first client. The first client code snippet includes identity information of origin servers, standard responses for network requests, and configuration parameters to configure programmable content delivery nodes to respond to the one or more network requests. The method also includes publishing the first client code snippet to a snippet library, and indexing the first client code snippet in the snippet library. The method also includes receiving, from a second client, a request for a second client code snippet. The method also includes selecting a subset of client code snippets stored in the snippet library. The method also includes rendering identification information for the subset of client code snippets, and outputting a selected client code snippet from the subset of client code snippets.

  • Patent number: 11483231
    Abstract: Exemplary methods, apparatuses, and systems include a path management hub and proxy server nodes that form a mesh network. The hub receives link performance metrics from each of the nodes. The hub determines optimal paths between first and second nodes for each of a plurality of metric types or a combination of metric types using the received link performance metrics. The hub maps a service identifier to a plurality of the determined optimal paths for a context representing one or more link performance metric types. The hub transmits a next hop for each of the plurality of mapped optimal paths along with the mapping to the first node. The first node receives the service identifier mapped to the next hops and traffic for the first connection. In response to determining the received traffic is for the service, the first node selects a first next hop and forwards the traffic.

  • Patent number: 10972572
    Abstract: A system and method are provided for processing network requests by a programmable delivery network. The method includes receiving client code snippets that include identity information of origin servers and standard responses for network requests. The system configures and causes programmable content delivery nodes to execute the client code snippets to respond to the network requests. In response to receiving the network requests, the method includes buffering and sending the requests to origin servers. The method further includes, while buffering the requests, obtaining and outputting responses to the requests by causing the programmable content delivery nodes to process the requests. The method also includes receiving responses from the origin servers and reconfiguring the programmable content delivery nodes to execute the client code snippets to respond to the network requests based on the received responses.

  • Patent number: 10873599
    Abstract: Computer systems and methods are provided for storing a first path profile. A computing device receives a first request to access a first location of a website, transmits the first request to a server, and receives a first cookie that includes identifying information for the first location. In response to receiving the first cookie, the device stores the identifying information. The device receives a second request to access a second location of the web site that is distinct from the first location. The second request includes the identifying information for the first location. The device transmits the second request to the server and receives a second cookie that includes the identifying information for the first location and for the second location. In response to receiving the second cookie, the device stores the first path profile that includes the identifying information for the first location and the second location.
