A method provides for a first networking node in a first network access to a second network by a mobile communication device including the steps: by a first gateway in the first network, extracting payload data and header information from a first data packet originating from the first networking node and addressed to a second networking node in the second network, and sending the extracted payload and header information as payload of a second data packet to the mobile communication device; and, by the mobile communication device, receiving the second data packet, retrieving therefrom the extracted payload and header information, and sending the extracted payload and header information as payload of a third data packet to the second gateway; and, by the second gateway, receiving the third data packet, retrieving therefrom the first data packet and forwarding the first data packet further to the second networking node.

According to an embodiment a method is disclosed for establishing a Multipath TCP connection comprising a first and second TCP connection between a client and a server. The client performs the steps of: sending a synchronization segment to the server indicative for a request to establish the first and second TCP connection, receiving a synchronization and acknowledgement segment from the server, establishing the first and second TCP connections, sending an acknowledgment segment to the server in order for the server to establish the first and second TCP connection.

Method and device for establishing multipath network connections

A data transfer connection between a device and another device can be established using a basic protocol having a multipath extension that allows for the data transfer connection to use several different paths in parallel. In establishing the data transfer connection, an intermediate device receives a connection request from the device. This connection request comprises an indication that the device is capable of handling the multipath extension. In addition, the connection request comprises an identification of the other device with which the data transfer connection is to be established. The intermediate device then determines whether the other device is capable of handling the multipath extension, or not. The intermediate device establishes the data transfer connection in accordance with the multipath extension if the other device is capable of handling the multipath extension. Otherwise, the intermediate device establishes the data transfer connection as a concatenation of data transfer connection portions.

A method of constructing a backup path in an autonomous system (AS) for failure of an inter-AS link is described. The method comprises identifying an alternate inter-AS path and constructing a tunnel to an end point on the alternate path.

The present invention concerns a method for use in a telecommunication network by a data traffic policer for data traffic policing on a data communication link. The data traffic includes data cells that are grouped into frames. For each data cell of a frame, upon reception of the data cell, the method checks a conformance of the data cell and provides a conformance result of the data cell being any one of conforming and non-conforming. The method further stores the data cell into a buffer and treats the frame as conforming in the event when for each data cell of the frame that is stored in the buffer the conformance result is conforming; and in the event when the frame is treated as conforming and upon reception of a predefined data cell of the frame, the method starts transmission of a predefined number of data cells of the frame by the traffic policer.

A shaping method for use by a shaper in a communication network for converting an incoming data flow with an incoming data packet rate into an outgoing data flow with an outgoing data packet rate. The shaper includes a buffer which is leaked at the outgoing data packet rate in order to provide the outgoing data flow. The shaping method determines a value of a future incoming data packet rate of the incoming data packet rate, and determines a buffer occupancy value related to the number of data packets of the incoming data flow received by the buffer included in the shaper. The buffer is leaked at the outgoing data packet rate in order to provide the outgoing data flow. The shaping method also determines the value of the outgoing data packet rate as a function of the value of the future incoming data packet rate, the value of the buffer occupancy, the value of a predetermined peak data packet rate and the value of a predetermined minimum data packet rate. This determination enables the shaper to support a service category with a predetermined minimum guaranteed bandwidth according to the predetermined minimum data packet rate. This also allows the shaper to use excess bandwidth over the predetermined minimum guaranteed bandwidth up to the predetermined peak data packet rate.

The present invention concerns a method for use in a telecommunication network by a data traffic policer (POL) for data traffic policing on a data communication link (L). The data traffic includes data cells that are grouped into frames (F , F , F , . . . ). The method comprises the step of for each data cell of a frame (F ), upon reception of the data cell, checking a conformance of the data cell and providing thereby a conformance result of the data cell being any one of conforming and non-conforming (F/T). The method further includes the steps of storing the data cell into a buffer (BUFF) and treating the frame as conforming in the event when for each data cell of the frame that is stored in the buffer (BUFF) the conformance result is conforming (F); and in the event when the frame is treated as conforming (F) and upon reception of a predefined data cell of the frame (F ), starting transmission of a predefined number of data cells of the frame (F ) by the traffic policer (POL).

A data traffic policer (POL) included in a telecommunication network, to police data traffic which includes data packets that are part of a lower order data flow that is on its turn part of a higher order data flow. Each data packet is associated to a lower order identifier (LOI) that identifies the lower order data flow and to a higher order identifier that (HOI) identifies the higher order data flow. The policer (POL) includes first determiner (DET ) coupled to an input of the policer (POL) to determine, upon reception of a data packet, its lower order identifier (LOI). A first controller (CTRL ) coupled to the first determiner (DET ) checks a conformance of the data packet according to predefined lower order conformance rules (LOC(LOI)) associated to its lower order identifier (LOI) and provides thereby a lower order conformance result (LOCR) that is lower order conforming or lower order non-conforming. Furthermore the policer (POL) includes second determiner (DET ) coupled to the input to determine the higher order identifier (HOI) that is associated to the data packet and forwards the higher order identifier (HOI) to a second controller (CTRL ). The second controller (CTRL ) checks a conformance of the data packet according to predefined higher order conformance rules (HOC(HOI)) associated to the higher order identifier (HOI) and provides a higher order conformance result (HOCR) that is higher order conforming or higher order non-conforming. The policer (POL) includes declarer (DECL) coupled between the first controller (CTRL ), the second controller (CTRL ) and an output (OUT) of the policer (POL). The declarer (DECL) declares, in the event when the lower order conformance result (LOCR) is lower order non-conforming, and the higher order conformance result (HOCR) is higher order conforming, the data packet as conforming. As a result, when being transmitted, the data packet uses some leftover bandwidth from another lower order data flow within the higher order data flow. After the heading, delete the title in its entirety.

The method shares available bandwidth on a common link in a communication network among a plurality of data flows which are transmitted via the common link. The method is used by a processor and includes sharing reserved bandwidth included in the available bandwidth among the plurality of data flows, and sharing unreserved bandwidth among the plurality of data flows according to a respective unreserved data packet share which is associated to each one of the plurality of data flows. The unreserved bandwidth is included in the available bandwidth in excess of the reserved bandwidth. The sharing of the unreserved bandwidth includes associating to one of the plurality of data flows a respective adaptable administrative weight and determining the respective unreserved data packet share which is associated to the one data flow as a function of its respective adaptable administrative weight.
