Methods and apparatus for efficiently directing communications are disclosed. On example entails receiving, from a mobile terminal, a communication directed to a cellular communication network, the communication being received in an alternative channel that differs from a channel of the cellular communication network. The communication is then converted for a relayed communication to the cellular communication network on behalf of the mobile terminal, the relayed communication being made through the cellular communication network.

Method and system for efficient communication

Systems and methods are provided hat enable an alternate display device to wirelessly receive content from a computing device, freeing users from the burden of physically connecting the computing device via a cable. The content sent to the display device can also be simultaneously or separately viewed on the computing devices of other nearby computing devices. Generic mechanism(s) and corresponding user interfaces are provided for computing devices to engage in discovery of devices to which content may be delivered, for accepting delivery and for initiating transmission of content.

Systems and methods for projecting content from computing devices

Device information for each of multiple devices associated with a user account is maintained by a cloud service. The device information can include credential information allowing the device to be accessed by other ones of the multiple devices, remote access information indicating how the device can be accessed by other ones of the multiple devices on other networks, and property information including settings and/or device drivers for the device. The device information for each of the multiple devices is made available to other ones of the multiple devices, and can be used by the multiple devices to access one another and provide a consistent user experience across the multiple devices.

Cloud-based device information storage

A relay communication system includes a relay server R that can communicate with a relay server R in another LAN through an external server S in a WAN. The relay server R stores account information of terminals T in the LAN, relay group information 100 on a group of relay servers R, and shared resource information 120 including a resource and accounts of the terminals T sharing the resource. The relay group information 100 and the shared resource information 120 include status information 107 and 127 indicating a status of the relay server R. The relay server R periodically performs an operation check to automatically update the status information 107 and 127.

Relay server and relay communication system

Multimedia communications with cross-layer optimization in multimedia communications with different user terminals. Various optimization for the delivery of multimedia content across different channels are provided concurrently to a plurality of user terminals.

Method and apparatus for multimedia communications with different user terminals

A system and method for interactive management of multiple wireless devices (such as PDA's or desktop or laptop computers) making graphical or video presentations while connected wirelessly to a display device whose wireless module converts the transmitted data from the wireless devices to the required format for display.

A normal way to specify network stack performance for a platform is by indicating the CPU utilization, and the code size (program memory usage) of the stack. This does not take into account performance characterization using different Ethernet packet payload sizes and then measuring the performance against the aggregated bandwidth across the network. This paper presents a realistic method of associating a network stack performance on a processor platform. It measures the CPU utilization of the platform for varied Ethernet packet sizes (200–1,500 bytes) versus a specified bandwidth throughput in the Ethernet channel ranging from 1Mpbs to 50 Mbps. CPU utilization of the platform is converted into a prorated DMIPS (Dhrystone Million Instructions per second).
