Abstract: Applications that run on an overlay network-based managed service achieve high performance gains using a set of TCP optimizations. In a first optimization, a typical single TCP connection between a client and an origin server is broken into preferably three (3) separate TCP connections. These connections are: an edge-to-client connection, an edge-to-edge connection, and edge-to-origin connection. A second optimization replicates TCP state along the connection to increase fault tolerance. In this approach, preferably a given TCP connection is maintained on two servers. When a packet is received by one server, called the primary, its state is updated and then passed to a second server, called the backup. Only when the backup sends an acknowledgement back to the primary can it then send a TCP acknowledgement back to the host that originally sent the packet. Another optimization reduces connection establishment latency.

Abstract: This disclosure relates to a surgical device configured to deliver implants and a method of repairing damaged tissue, such as meniscus tears. One exemplary surgical device includes a cannula and a pusher moveable within the cannula to deploy a plurality of implants. Movement of the pusher in the distal direction deploys a distal-most implant and moves any additional implants distally within the cannula. Thus, multiple implants can be loaded into the cannula and deployed using one pusher. The disclosed arrangement is easy to use and has fewer component parts compared to prior devices, which in turn increases the ease of manufacture and reduces cost.
