Abstract
The invention relates to a method for establishing a connectionless bearer service and a method for forwarding data packets in a connectionless bearer service. The data packet has a virtual access network identifier in the header data. The virtual access network identifier defines a unique data path from a source to a destination of the data packet and vice versa. The invention further relates to a network node for forwarding data packets based on a virtual access network identifier received with the data packets and by using a forwarding table for forwarding the data packets.
Claims14
Method for establishing a connectionless bearer service, the method comprising:
- transmitting a data packet comprising user data and header data, the header data comprising at least a virtual access network identifier, wherein the virtual access network identifier is a unique identifier defining a unique virtual access network for the connectionless bearer service, the virtual access network defining a unique data path from a source to a destination of the data packet and vice versa.
Method for forwarding data packets in a connectionless bearer service, the method comprising:
- forwarding a data packet comprising user data and header data, the header data comprising at least a virtual access network identifier, wherein the virtual access network identifier is a unique identifier extending across virtual networks and defines a unique virtual access network for the connectionless bearer service, the virtual access network defining a unique data path from a source to a destination of the data packet and vice versa.
Network node for forwarding data packets in a connectionless bearer service, the network node comprising:
- a receiver for receiving a data packet comprising user data and header data, the header data comprising at least a virtual access network identifier, wherein the virtual access network identifier is a unique identifier extending across virtual networks and defining a unique virtual access network for the connectionless bearer service, the virtual access network defining a unique data path from a source to a destination of the data packet and vice versa;
- a source address analyser for analysing the source of a data packet according to the header data of the data packet;
- a memory configured to store a forwarding table, the forwarding table indicating the network node one level lower in the hierarchy of the virtual access network from which the data packet was received and a source address of the data packet;
- and
- a transmitter for sending a data packet to a network node one level lower in hierarchy of the virtual access network according to the information stored in the forwarding table.
