Abstract
There is disclosed a method for switching IP packets between client networks and IP provider networks by way of an access network. In a network element of the access network an IP session between a client network and an IP provider network is registered by means of a Layer 2 address assigned to the client network and an IP address assigned to this Layer 2 address. In the network element an IP service connection between the network element and an IP provider network is defined by means of a Layer 2 address assigned to the IP provider network. Further an active IP session is assigned to at least one IP service connection and/or a plurality of active IP sessions are assigned to the same IP service connection. In the network element the switching of the IP packets from active IP sessions to service connections and vice versa is performed by means of the aforementioned assignments.

31. A method for switching IP packets between a client network and an IP provider network based upon an access network having a network element, comprising:
-
registering an IP session between the client network and the IP provider network in the network element based upon a first Layer 2 address assigned to the client network and an IP address assigned to the first Layer 2 address;
defining an IP service connection between the network element and an IP provider network in the network element based upon a second Layer 2 address assigned to the IP provider network;
assigning an active IP session to at least one IP service connection or assigning a plurality of active IP sessions to one IP service connection; and
switching the IP packets from active IP sessions to service connections via the network element based upon the assignments in the network element. - View Dependent Claims (32, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

33. A method for switching IP packets between a client network and an IP provider network based upon an access network having a network element, comprising:
-
registering an IP session between the client network and the IP provider network in the network element based upon a second Layer 2 address assigned to the provider network and an IP address assigned to the second Layer 2 address;
defining an IP service connection between the network element and an client network in the network element based upon a first Layer 2 address assigned to the IP client network;
assigning an active IP session to at least one IP service connection or assigning a plurality of active IP sessions to one IP service connection; and
switching the IP packets from active IP sessions to service connections via the network element based upon the assignments in the network element.

49. A network element of an access network, comprising:
-
a registration of an IP session between a client network and an IP provider network based upon a first Layer 2 address assigned to the client network and an IP address assigned to the first Layer 2 address, a definition of an IP service connection between the network element and an IP provider network based upon a second Layer 2 address assigned to the IP provider network, an assignation of an active IP session to at least one IP service connection or an assignation of a plurality of active IP sessions to the IP service connection, and a switching of the IP packets from active IP sessions to service connections based upon the assignments. - View Dependent Claims (50, 51, 52, 53)

54. A method for switching IP packets between a client network and an IP provider network via an access network having a network element, comprising:
-
registering an IP session between a client network and an IP provider network based upon a client-network-side Layer 2 address and an IP address assigned to this client-network-side Layer 2 address;
defining an IP service connection between the network element and an IP provider network based upon a provider-network-side Layer 2 address;
determining the affiliation to an IP session based upon a client network for a received IP packet based upon the client-network-side Layer 2 client address and the IP address assigned to this Layer 2 address;
forwarding the IP packet to the IP provider network via at least one service connection assigned to this IP session;
determining an affiliation to an IP service connection by an IP provider network for a received IP packet based upon the provider-network-side Layer 2 address and the IP address assigned to the provider-network-side Layer 2 address; and
forwarding the IP packet to the client network based upon at least one IP session assigned to this IP service connection.
