Abstract
The invention relates to a method for multiplexing data packets from different IP hosts to one multiplexing packet before it is sent to a destination IP host, where the different data packets in the multiplexing packet are distributed to the different destination IP hosts.
Claims13
A method of transmitting data packets in an IP network from a plurality of source IP hosts to a plurality of destination IP hosts, the method comprising the steps of:
- collecting, by a source multiplexer, data packets from a plurality of source IP hosts, the multiplexer multiplexing said data packets in a multiplexing packet,
- adding a source IP address of the source multiplexer to the multiplexing packet,
- adding the destination IP address of a destination multiplexer to the multiplexing packet, the destination multiplexer being connected to a plurality of destination IP hosts,
- adding, for each data packet, a destination information of a destination IP host, to which the respective data packet is to be distributed, to the multiplexing packet, the destination multiplexer identifying the destination IP host for each data packet on the basis of the destination information, and
- transmitting the multiplexing packet to the destination multiplexer on the basis of the destination IP address of the destination multiplexer.
A method of demultiplexing a multiplexing packet transmitted from a source multiplexer in an IP network with a plurality of source IP hosts, the multiplexing packet containing a plurality of data packets of different source IP hosts, the method comprising the steps of:
- extracting a destination information contained in the multiplexing packet for each data packet contained in the multiplexing packet for determining to which destination IP host each data packet is to be distributed, and
- distributing each data packet to the data packet's destination IP host based on the extracted destination information.
A source multiplexer multiplexing data packets transmitted in an IP network from a plurality of source IP hosts, the source multiplexer comprising:
- a multiplexing unit configured to collect data packets from a plurality of source IP hosts, and configured to multiplex said data packets in a multiplexing packet,
- an IP address generating unit inserting a source IP address and a destination IP address to an IP header of the multiplexing packet, the IP address generating unit furthermore adding, for each data packet, a destination information of a destination IP host, to which the respective data packet is to be distributed, to the multiplexing packet, and
- a transmitter transmitting the multiplexing packet to the destination multiplexer on the basis of the destination IP address of the destination multiplexer.
A destination multiplexer demultiplexing a multiplexing packet transmitted from a source multiplexer in an IP network with a plurality of source IP hosts, the multiplexing packet containing a plurality of data packets of different source IP hosts, the destination multiplexer comprising:
- a destination determination unit for determining a destination IP host for each data packet, the destination determination unit extracting a destination information contained the multiplexing packet for each data packet contained in the multiplexing packet for determining to which destination IP host each data packet is to be distributed, and
- a distributor distributing each data packet to the data packet' destination IP host based on the retrieved destination information.
