Abstract: The present application presents systems and methods for handling by an HTTP virtual server (HTTPVS), connections via which non-HTTP data is transmitted between clients and servers. HTTPVS intercepts a request from a client to establish first transport layer connection (TLC) with a server. HTTPVS establishes second TLC with the servers in response to receiving an acknowledgment from a client to establish the first TLC. HTTPVS determines if a first network packet transmitted via first TLC comprises an HTTP payload or non-HTTP payload. If HTTPVP the first network packet includes HTTP payload, HTTPVS may process all transmissions from the first TLC in accordance with connection tracking and forward the processed transmissions to the server via the second TLC. If HTTPVS determines that the first network packet does not include an HTTP payload, HTTPVS may link the first TLC and the second TLC so the client and server exchange non-HTTP communication without interruption.

Abstract: The virtual Server (vServer) of an intermediary device deployed between a plurality of clients and services supports parameters for setting maximum segment size (MSS) on a per vServer/service basis and for automatically learning the MSS among the back-end services. In case of vServer/service setting, all vServers will use the MSS value set through the parameter for the MSS value set in TCP SYN+ACK to clients. In the case of learning mode, the backend service MSS will be learnt through monitor probing. The vServer will monitor and learn the MSS that is being frequently used by the services. When the learning is active, the intermediary device may keep statistics of the MSS of backend services picked up during load balancing decisions and once an interval timer expires, the MSS value may be picked by a majority and set on the vServer. If there is no majority, then the highest MSS is picked up to be set on the vServer.

Abstract translation: 部署在多个客户端和服务之间的中间设备的虚拟服务器（vServer）支持用于在每个vServer /服务基础上设置最大段大小（MSS）的参数，并用于在后端服务中自动学习MSS。 在vServer /服务设置的情况下，所有vServer将使用通过该参数设置的MSS值，以将TCP SYN + ACK中设置的MSS值设置为客户端。 在学习模式的情况下，后端服务MSS将通过监视器探测来学习。 vServer将监视和学习服务频繁使用的MSS。 当学习活动时，中介设备可以保持负载均衡决策期间所接收的后台服务的MSS的统计信息，并且一旦间隔定时器到期，则MSS值可以通过多数被选择并设置在vServer上。 如果没有多数，那么最高的MSS被拾取在vServer上设置。

Abstract: The present solution is directed to a system for handling network interface card (NIC) congestion by a NIC aware application. The system may include a device having a plurality of network interface cards (NICs), a transmission queue corresponding to a NIC of the plurality of NICs; and an overflow queue for storing packets for the NIC when congested. The system may also include an application executing on the device outputting a plurality of packets to the transmission queue responsive to detecting that the NIC is identified as not congested. The device identifies the NIC as congested responsive to determining that a number of packets stored in the transmission queue has reached a predetermined threshold and responsive to detecting identification of the NIC as congested, the application stores one or more packets to the overflow queue. The device transmits one or more of the plurality of packets stored in the transmission queue and transmits a predetermined number of packets from the overflow queue.
