Abstract: The present invention relates to a method for transporting data between a data transmitting network element and a data receiving network element via a point-to-point connection in a communications network. This communications network comprises at least one transmitting network element and at least one data receiving network element. An Internet Protocol Control Protocol request for a service level of sending data is sent to the data receiving element by the data transmitting element. This Internet Protocol Control Protocol request is received by the data receiving element. The data receiving element then determines a service level based on a predetermined criterion and formulates an Internet Protocol Control Protocol propose of the service level that can be provided to the data sending element. Subsequently the Internet Protocol Control Protocol propose of the service level is sent towards the data transmitting element.

Abstract: A Internet forwarding method, related system and related devices to be used for forwarding internet packets from a host connected to an internet towards a destination host connected to a private internet network and vice versa, where an internet network and a private internet network are coupled through at least one edge router, and where the destination host is assigned a global Internet address, and wherein the forwarding of the internet packets from one of at least one edge router towards the destination host and vice versa, is based only on the global internet address.

Abstract: The invention relates to a communications network for exchanging data packets of ATM connections in which, in network nodes of a lower network level, a data bank is provided in which connection data are kept available, wherein each data bank in a network node of a lower network level (L1) keeps available connection data for a closer environment (PGA1, . . . , PGA4, . . . , PGC), that at least one additional data bank (RSA1, . . . , RSC), which keeps available connection data for a wider environment, is provided and assigned to a network node, and that network node of a higher network level (e.g. A.1) which is responsible for a network node (A.1.

Abstract: Method for auto-configuration of Customer Premises Equipment (CPE) in a digital subscriber line access aggregation network, where the CPE establishes a Label Switched Path to a Broadband Remote Access Server (BRAS) and obtains configuration data via IP protocol.

Abstract: The invention relates notably to a method for enabling a user registered in an Network Access Server as already connected to a Virtual Private Network to communicate with at least a communication device not belonging to the Virtual Private Network. The Network Access Server enables access over a data communication network to the communication device as well as to a plurality of Virtual Private Networks.

Abstract: A method for rerouting a connection set up along a path calculated between a first node (A.1.2) and a second node (C.2), of a switching network structured into a plurality of peer groups at at least two hierarchical levels, implies that within a peer group along said path, of not the highest hierarchical level, a local alternative path within this peer group is established between an entering border node and an outgoing border node of said peer group, based on path information stored within this entering border node during set up of the connection, and including an identifier of said outgoing border node of said peer group. In a variant method this path information is stored within each entering border node of each peer group, thereby allowing the local alternative path to be established in the lowest level peer group possible.
