Embodiment Construction

[0021] Referring now to the drawings, wherein like reference numerals refer to similar or identical parts throughout the several views, and more particularly to FIG. 1 thereof, which shows a telecommunications system 10 . The system 10 includes a first device 12 having multiple interfaces, where each interface has a unique MAC address, which the first device 12 uses to forward frames. The system 10 includes at least one bridge 16 in communication with the first device 12 . The system 10 includes a second device 18 that communicates with the first device 12 through the bridge 16 and has multiple interfaces, where each interface has a unique MAC address. The first device 12 forwards the frame to the first interface 14 of the plurality of interfaces of the second device 18 using the unique MAC address of the first interface 14 of the second device 18 .

[0022] Preferably, the system 10 includes a first end station 20 and a second end station 22, and wherein at least a second in...

Abstract

A telecommunications system includes a first device having a plurality of interfaces, with each interface having a unique MAC address, the first device using the MAC addresses for forwarding frames. The system includes at least one bridge in communication with the first device. The system includes a second device in communication with the first device through the bridge having a plurality of interfaces with each interface having a unique MAC address, the first device forwarding frames to a first interface of the plurality of interfaces of the second device using the unique MAC address of the first interface of the second device. A method for communicating is also provided.

Description

technical field [0001] The present invention relates to forwarding frames between devices using unique MAC addresses having multiple interfaces, each interface having a unique MAC address. More specifically, the present invention relates to forwarding frames between devices using unique MAC addresses having multiple interfaces, where each interface has a unique MAC address based on a far-side MAC address. Background technique [0002] Current technology solutions include 802.1Q (VLAN), IEEE 802.lah (provider backbone bridging) and 802.1D bridging. [0003] These basic solutions are known for inefficient use of available links - due to the use of one (or more) STP (Spanning Tree Protocol) variants, which effectively block ports (and corresponding links) - making them unusable . [0004] The schemes discussed so far to provide a better way to utilize redundant links include: [0005] MSTP: MSTP utilizes VLAN grouping to derive distinct spanning trees - where one or more VLA...
