Communication apparatus reliably connected inside

Abstract

The invention discloses a communication equipment whose inside parts are reliably connected with each other, relating to the communication equipment, which can realize the reliable interconnection communication among frames and among veneers inside the equipment, based on the present hardware configuration and on the premise that the bandwidth utilization is assured. Wherein, a port binding technology is adopted to realize the reliable interconnection of the parts inside the communication equipment; through the port binding, two physical otter boards, which are backups for each other, are bound and communicated to form a logic otter board; service boards inside the frames are all port bound with the two physical otter boards to realize the communication inside the frames, and the logic otter boards among different frames are all interconnected; the physical otter boards inside one frame are also bound and interconnected; on such basis, the service boards or the otter boards can select ports to communicate to realize the average distribution of the traffic load at the ports, and automatically give up the link when the ports are in fault to realize the protection switching of the link grade.

Description

technical field [0001] The invention relates to communication equipment, in particular to the interconnection technology of individual boards inside the communication equipment. Background technique [0002] Communication systems are required to provide reliable and uninterrupted services to their users, especially in some important business applications, such as electronic money, order processing, customer service, inventory management, e-mail and Internet access, etc., business survivability becomes more important than ever, with availability requirements of 99.999% and beyond. Therefore, the network survivability has become an important factor affecting network design and construction, and the equipment used in the communication system needs to have high reliability accordingly. [0003] In this regard, a commonly used solution is redundant backup and active-standby switching technology. [0004] Redundant backup and active / standby switching technologies have various ba...

AI Technical Summary

Problems solved by technology

[0010] In practical applications, the above scheme has the following problems: low system reliability, poor link stability, additional hardware needs to be added, and link bandwidth utilization is only half of the actual system configuration

Since the two physical network boards are active and standby, only one of the physical network boards communicates with the service board at any time, and the link between the service board and the other physical network board does not work, so the link bandwidth utilization low rate
