  • Methods for preserving flow state during virtual machine migration and devices thereof
    Patent number: 9141625
    Abstract: Methods, computer-readable media, and apparatuses for network flow state preservation include migration of at least one application hosted on a first server device to a second server device coupled to a second traffic management device is detected at a first traffic management device. At least a portion of connection state information associated with a network connection between at least one client device and the application is communicated by the first traffic management device to the second traffic management device via a communication channel between the first and second traffic management devices. The application is provided by the first traffic management device to the at least one client device during the migration based upon the connection state information.

  • Multi-output packet server with independent streams
    Patent number: 8671163
    Abstract: A method of serving content to multiple clients via a network is provided. Independent sessions with each of a plurality of clients are maintained, wherein the number of clients in the plurality of clients can vary over time, and wherein the start of each session and the end of each session can be independent of the start and end of other sessions. A stream of packet payloads is received, each packet payload of the stream of packet payloads including data generated from the content, wherein each packet payload in at least a subset of the stream of packet payloads includes a different set of data. Each packet payload in the stream of packet payloads is transmitted to each client of the plurality of clients in corresponding packets, wherein the packet payload transmitted to a client at any particular time is independent of the state of the corresponding session.
