    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: A network appliance is provided for establishing sessions between client devices and a network server(s) for exchanging network traffic therebetween. The network appliance may include a memory and a processor cooperating with the memory, with the processor being operable in a normal traffic mode and a forwarding traffic mode. The processor may be configured to establish new sessions for network traffic based upon new session requests from the client devices, and forward network traffic associated with prior existing sessions from the client devices to the network server(s). When in the forwarding traffic mode, the processor may forward network traffic not associated with a prior existing session or a new session request to the network server(s). When in the normal traffic mode, the processor may block network traffic not associated with a prior existing session or a new session request from reaching the network server(s).

    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.
