AI Technical Summary

Problems solved by technology

Loops occur when there is more than one valid path between any two communication bridges and they can cause network instability by providing the possibility of broadcast storms or excess broadcast data
When loops exist in the network, bridges can repeatedly rebroadcast broadcast messages, potentially overwhelming the network's ability to handle large volumes of messages

Embodiment Construction

[0017] Embodiments of the invention will be described more fully following this specification with reference to the accompanying drawings in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth in this specification; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

[0018] Embodiments of the present invention may provide apparatus, systems and methods for loop containment enhancement in communication networks. In some embodiments, a more robust communication network with greater immunity to broadcast storm failures may be achieved. Such improvements may be required to provide a communication network free of loops. In one aspect, loop-free can be established by sending a message fro...

Abstract

Systems, methods, and apparatus for providing a communication network free of bridge loops by providing a first message from one of two bridges and a second message in response to the first message from the other of the two bridges and establishing a communicative path if both the first and second messages were received.

Description

technical field [0001] The present invention relates generally to computer communication networks, and in particular to methods, apparatus and systems for preventing loops within the network. Background technique [0002] A computer communications network, such as a local area network (LAN), typically has several bridges with multiple links interconnected between the several bridges to carry data between them. These several bridges in the network have various levels of connectivity in terms of both the number of accesses to a particular bridge and the number of other bridges a particular bridge is connected to. Each of these bridges can have multiple ports that can be used to establish a point-to-point link from the bridge to another bridge or to a terminal such as a desktop computer. The ports of each of these bridges can be selectively activated or deactivated based on whether a particular link is required in the network. [0003] Many times there is also a hierarchy ass...
