A method is provided for selectively routing data packets on a client device having of plurality of network interfaces for communicating over a network. The method comprising the following steps. It is determined if the data packets should be routed to a network server accessible by a corresponding one of the network interfaces to access local resources offered thereon. If the data packets should be routed to the network server, the data packets are routed directly to the network server via the corresponding network interface. Otherwise, the data packets are routed via a default route. A client device configured to implement the method is also provided.

Accessing local network resources in a multi-interface system

A network component is provided for facilitating communication of traffic between a destination server and a client over a network comprising the plurality of network paths. The network component comprising memory for storing computer-readable instructions and a processor configured to implement the computer-readable instructions. The computer-readable instructions operable to implement the following: exchange control parameters with the client via a control channel using one or more of the plurality of network control paths; encapsulate the traffic for transmission to the client; decapsulate the traffic received from the client; and schedule traffic to the client via one or more of the plurality of network paths using logic common with the client based on network parameters. A client configured to work with the network component is also described, as is a communication system including both the client and network component.

Encapsulation system featuring an intelligent network component

A method for encapsulating a packet of data from a data flow is described. The packet comprises a flow network header for identifying a source network address and a target destination network address and a flow transport network header for identifying a source port and a target destination port. The method comprises the following steps. The flow network header is replaced with an encapsulation network header for identifying an encapsulation network address and a decapsulation network address. The decapsulation network address specifies the address of a decapsulation node. The flow transport header is replaced with an encapsulation transport header for identifying an encapsulation port and a decapsulation port. The decapsulation port is configured to be the same as the target destination port. A method for decapsulating the encapsulated packet, as well as network nodes configured to implement the methods, are also described.

Encapsulating traffic while preserving packet characteristics

A method is described for reducing a load placed on an endpoint server acting as an endpoint of a tunnel from a client device across a network. The method, implemented at the client device, comprises the following steps. A request to establish a new network connection is received. A risk of establishing the new network connection outside of the tunnel is determined based on a plurality of predefined criteria. The determined risk is compared with a predefined risk threshold and, if the determined risk is less than or equal to the predefined risk threshold, the new network connection is established directly via the network. If the new network connection fails before it is completed it is re-established via the tunnel. If the determined risk is greater than the predefined risk threshold, the new network connection is established via the tunnel. A client device and computer-readable medium configured to implement the method is also described.
