A wireless station associates with an access point to join a wireless local area network (WLAN). The access point is part of the WLAN and operates as a switching device between wireless stations of the WLAN. The wireless station forms a TCP session via the access point with an external device which is external to the WLAN. The wireless station exchanges (i.e., transmits and/or receives) a first sequence of packets on the TCP session. The wireless station receives a frame from the access point, the frame indicating that the wireless station has been disassociated after having associated earlier with the access point. The wireless station re-associates with the access point. The access point then communicates with the external device on the TCP session after re-associating, the communicating involving exchanging a second sequence of packets with the external device after the re-association.

The present disclosure relates generally to communication with payment terminals via TCP/IP protocol. Using network technology and novel processes, in particular embodiments, the present systems and methods facilitate local network discovery and communication between a payment terminal and an electronic cash register (ECR) via a browser. For example, in certain embodiments, the present systems and methods leverage TCP/IP network technology to securely facilitate communications between SaaS ECR software running in a browser environment and one or more payment terminals.

Systems, methods, and machine-readable media for low latency server-side redirection of User Datagram Protocol (UDP)-based transport protocols traversing a client-side Network Address Translation (NAT) are provided. A request may be sent from a client for a data resource to a first server. The data resource may be received from a second server that has not been previously connected to the client. Receiving the data resource from the second server may be facilitated by the first server through redirecting the request to the second server and providing for the second server to connect to the client and directly respond to the request. The first server may lack at least one of the requested data resource or resources for providing the requested data resource.

Systems, methods, and instrumentalities are disclosed for providing Information Centric Networking (ICN) within a network, comprising detecting a request for content from a wireless transmit/receive unit (WTRU) that is in the network, selecting a network element for the WTRU to attach to, wherein the network element is selected without regard to properties of the content requested, and providing the content to the WTRU. A request to publish content from a WTRU in the network may include determining, based on content name, whether to publish the content in the network or outside the network, and if the content is to be published in the network, selecting a network element for the WTRU to attach to, wherein the network element is selected without regard to properties of the content requested, and causing the network element to accept the content from the WTRU.

Methods and apparatus for remapping IP addresses of a network to endpoints within a different network. A provider network may allocate IP addresses and resources to a customer. The provider network may allow the customer to remap an IP address to an endpoint on the customer's network. When a packet is received from a client addressed to the IP address, the provider network may determine that the IP address has been remapped to the endpoint. The provider network may translate the source and destination addresses of the packet and encode the packet for transmission over a private communications channel. The encoded packet may be sent to the endpoint via the private communications channel over an intermediate network. Response traffic may be routed to the client through the provider network, or may be directly routed to the client by the customer network.

A communication device and method of operating the same. The method may include initiating a first connection between a client device and a proxy server application and a second connection between the proxy server application and the remote server while advertising a proxy-window-scale-value, and splicing the TCP connections below a transport layer. The method also includes left shifting a window size of a client-sourced-packet to obtain an originally intended client-window size, right shifting the originally intended client-window size by the proxy-window-scale-value, and providing the client-sourced-packet to the server with the proxy-window scaled value. In addition, the method includes receiving a server-sourced-packet from the remote server, left shifting a window size of the server-sourced-packet by the server-window-scale value to obtain an originally intended server-window size, right shifting the originally intended server-window size by the proxy-window-scale-value, and then providing the server-sourced-packet to the client with the proxy-window scaled value.

A transmission apparatus that includes circuitry configured to generate transport protocol selection information used for selecting a transport protocol to be used in a specific service from a plurality of transport protocols conforming to a predetermined standard; and transmit, together with the transport protocol selection information, a content provided by the specific service according to the transport protocol set in the transport protocol selection information, and the plurality of transport protocols include at least ROUTE (Real-Time Object Delivery over Unidirectional Transport) and MMT (MPEG Media Transport).

An application processor sends a TCP packet to the modem, where the TCP packet is used by the modem to generate a wireless protocol data packet corresponding to the TCP packet, so that the modem sends the wireless protocol data packet to a base station. The application processor receives first status information from the modem, where the first status information is status information of the wireless protocol data packet or status information of the TCP packet. The application processor determines, based on the first status information, whether the TCP packet is successfully sent to the base station. If the TCP packet is successfully sent to the base station, the application processor starts a retransmission timer corresponding to the TCP packet. If the TCP packet is not successfully sent to the base station, the application processor sends the TCP packet to the modem again.

A PON system that includes an optical line terminal that processes TCP ACK packets in a manner to reduce the bandwidth used.
