Systems and methods that efficiently combine multiple wireless networks or devices resulting in faster, more reliable, and more secure mobile Internet. A Virtual Private Network (VPN) service application is operated to route outgoing and incoming data packets of a mobile device. The mobile device is (i) either coupled to a remote server through the VPN service application for data packets transfer between the remote server and the mobile device or (ii) performs cross-layer translation for data packets transfer between the mobile device and direct target hosts on the Internet. Concurrently using multiple channels secures data packets transfer by sending encrypted data packets over multiple channels and receiving the encrypted data packets by a single apparatus. Data packets are designated to be transferred via a Wi-Fi channel or a cellular channel, and then transferred using both the Wi-Fi channel and the cellular channel.

The present invention discloses a method of data retransmission in coordination service transmission and access network gateway thereof. Wherein, the method includes: in coordination service transmission, access network gateway receives the service data requested by the coordination terminal, caches the data and transmits it to the corresponding destination terminal; the access network gateway executes retransmission strategy, and when decides data retransmission is needed, retransmits the cached data to the corresponding destination terminal. The access network gateway is used to receive the service data requested by the coordination terminal, to cache the data and transmit it to the corresponding destination terminal, to retransmit the cached data to the corresponding destination terminal when data retransmission is needed. Using the present invention, to the problem of service data retransmission in coordination service transmission, the service data transmission efficiency is effectively improved.

A network access method includes: establishing a BLUETOOTH connection to a BLUETOOTH terminal; receiving, using the BLUETOOTH connection, a network access request from the BLUETOOTH terminal; and when the BLUETOOTH terminal is an authorized device, activating a BLUETOOTH network sharing function automatically and forwarding the network access request to a wide area network.

Techniques for realizing service chaining, a corresponding apparatus and an SDN (Software Defined Network) controller are disclosed. The method includes temporarily modifying an original destination MAC (media access control) address of a packet and an original source MAC address the packet during the time the packet makes a hop from one middlebox to another. A restore operation is used to restore the original source and destination MAC addresses after the hop is made.

The invention concerns computer systems that are specially adapted to propagate content over a dynamic network, substantially in real time, by virtue of the locational proximity of network joined client computers. Preferably, the content will also be proximity-weighted, and more preferably also rank-weighted, topic-weighted, time-weighted, query-weighted, vote-weighted, and/or location-weighted. The invention particularly concerns such computer systems that employ more than one such weighting. The invention particularly concerns such computer systems that operate using, or through, mobile devices, particularly for distributed computing applications, including social media applications and communications applications conducted over Restricted Computer Networks.

The present invention discloses methods and systems for transmitting data packets through a plurality of connections and through a gateway at a network node. The network node receives network performance observation report (NPOR) from the gateway. Based on the NPOR, the network node determines at least one of the plurality of wide area network (WAN) interfaces of the gateway for transmitting data packets. The network node then creates and transmits an instruction to the gateway. When the network node transmits the data packets to the gateway, the network node also creates and transmits an instruction to the gateway to determine the WAN interface(s) of the gateway for transmitting the packets.

It is provided a method, comprising detecting a request for establishing a session between a peer and a network, wherein the request is received from the peer and comprises an identifier of a user of the network; checking, if the request is detected, whether a first session is established, wherein the first session is a session of the user which is established between the peer and the network; determining, if it is checked that the first session is established, whether the first session is dead or alive; flushing the first session if it is determined that the first session is dead; triggering an establishment of the requested session if it is determined that the first session is dead.

The invention relates to a radio-communication system for Push-to-Talk applications, comprising: a narrow-band PMR-technology terminal capable of connecting, via a radio-electric interface, to a narrow-band network infrastructure for accessing, via a PTT server, a set of narrow-band PTT resources or applications; and a wide-band-technology terminal capable of connecting, via a radio-electric interface, to an IP-WAN network for accessing, via a server, a set of wide-band PTT resources or applications, wherein said terminal comprises a client PTT application on the IP-WAN network configured to establish an IP connection between the terminal and a PTT server over the IP-WAN via an interface, such that said terminal can access the narrow-band PTT resources or applications and establish a communication channel with the terminal.

The at least one distributed virtual CPE comprising at least one IP Edge node, at least one Carrier Grade NAT node, at least one User Configuration Server and at least one Line Configuration Server, the method creating said at least one distributed virtual CPE upon the reception of traffic from a home in the access line corresponding to said home; modifying said at least one distributed virtual CPE upon a customer request; removing said at least one distributed virtual CPE, upon a traffic inactivity timeout detected in said access line or upon an administrative command; and associating a line identifier and a customer identifier to said at least one distributed virtual CPE, wherein said association, termed vCPE context, is known partially or totally by the at least one IP Edge node, the at least one Carrier Grade NAT, the at least one User Configuration Server and the at least one Line Configuration Server, and is kept active during the whole life cycle of said distributed virtual CPE from the creation to the removal.

Provided are a method, an apparatus and a system for establishing an optical bypass. The method includes: a route controller sending an optical bypass establishment request carrying information about an ingress node, an egress node and a required bandwidth to an optical transmission controller; and setting a second flow forwarding entry corresponding to the optical bypass for the ingress node and the egress node and sending the set second flow forwarding entry to the ingress node and the egress node when receiving an establishment success notification sent by the optical transmission controller, the establishment success notification being used for indicating that the optical transmission controller has allocated the optical bypass according to the optical bypass establishment request, set a first flow forwarding entry corresponding the bypass for each optical transmission device in the optical bypass, and sent the set first flow forwarding entry to a corresponding optical transmission device.
