    Abstract: Systems and methods of providing fine grained control over MSS values of transport layer connections. A device intermediary to a plurality of clients and a plurality of servers can identify a first MSS value based on a MTU value of a VLAN interface responsive to a request to establish a transport layer connection. Device determines that a MSS value of the VLAN is less than the first MSS value. Device updates, responsive to the determination, the first MSS value to a second MSS value corresponding to the MSS value of the VLAN. Device determines that an MSS value specified by a profile configured for a virtual server of the device is less than the second MSS value. Device updates the second MSS value to the MSS value of the profile responsive to determining that the MSS value specified by the profile is less than the second MSS value.

    Abstract: Described embodiments provide systems and methods for upgrading user space networking stacks without disruptions to network traffic. A first packet engine can read connection information of existing connections of a second packet engine written to a shared memory region by the second packet engine. The first packet engine can establish one or more virtual connections according to the connection information of existing connections of the second packet engine. Each of the first packet engine and the second packet engine can receive mirrored traffic data. The first packet engine can receive a first packet and determine that the first packet is associated with a virtual connection corresponding to an existing connection of the second packet engine. The first packet engine can drop the first packet responsive to the determination that the first packet is associated with the virtual connection.

    Abstract: Systems and methods of vertical auto-scaling a networking stack by adjusting the number of packet engines executing on a device are provided. A device intermediary to clients and servers executes first packet engines to process network traffic of a first set of connections. The device determines to adjust the number of packet engines executing on the device based on trigger parameters. The device activates second packet engines to process network traffic for a second set of connections. The device mirrors the network traffic from the first and second set of connections. The first packet engines reject the traffic from the second connections, and the second packet engines reject the traffic from the first connections. The device deactivates the first packet engines when the first connections timeout.

    Abstract: The present disclosure is directed towards systems and methods for transmitting data packets to a software container executing on a host computing device. A network service can be enabled within a software container established on the host computing device. A data packet of a request formatted according to the network service can be received via a first port of a first subnetwork assigned to the host computing device. The data packet can be forwarded to a second port assigned to the software container, responsive to a network address translation rule associating the second port assigned to the software container with the first port of the host computing device. The second port can be a port of a second subnetwork assigned to the software container. The data packet can be processed according to the network service within the software container.

    Abstract: This disclosure is directed generally to systems and methods for implementation of Jumbo frames in an existing network stack. In some embodiments, a connection handler of a device receives data having a size greater than an Ethernet frame size. That data includes header data and payload data. The device partitions the data into segments including a first segment and a second segment. The first segment includes the header data and a first portion of the payload data, while the second segment includes a second portion of the payload data. The device stores the first and second segments in first and second network buffers, respectively, of a pool of network buffers. The device forms a packet chain of the first and second network buffers having a size greater than the Ethernet frame size. The device transmits the packet chain via a network connection.
