Title:

METHOD OF SENDING A PACKET THROUGH A NODE

Document Type and Number:

WIPO Patent Application WO2005072219

Kind Code:

A3

Abstract:

The method is for sending information through a node (unit 234 of Fig 1) and includes providing a node that has a first access port (unit U1 of Fig 1), a second access port (unit U2 of Fig 1), a first uplink (unit 218 of Fig 1) and a second uplink (unit 220 of Fig 1). A first packet is sent via the first access port to the node. When the node is in a leaf mode, the node creates a tag inside the first packet. The tag contains a first port number corresponding to the first access port. When the node is in a branch node, the node adds the first port number to the tag and sends the packet in the first uplink and the second uplink. A second packet, received via the second access port, is sent via the first uplink of the node. The node receives the second packet.
