Embodiment Construction

[0046] In order to solve the technical problems proposed by the present invention, the specific realization of the scheme of the present invention includes:

[0047] Physically connect the external time port of each switch in the stacking system; determine the switch used for time synchronization, and use the switch as the synchronization time source; take the synchronization time source as the reference, follow the external time port of the switch in turn The physical connection configures the input and output states of the external time ports of each switch; the synchronization time source synchronizes the time to each switch in the stack system according to the physical connection of the external time ports of the switches and the configured input and output states of the external time ports.

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction...

Abstract

The present invention provides a time synchronization method in a switch stacking system, the method comprising: physically connecting the external time ports of each switch in the stacking system; determining the switch used for time synchronization, and using the switch as a synchronization time Source; with the synchronous time source as a benchmark, the input and output states of the external time ports of each switch are configured according to the physical connection of the external time port of the switch successively; the external time of the physical connection and configuration of the synchronous time source according to the external time port of the switch The time is synchronized to each switch in the stack system based on the input and output status of the ports. The present invention also discloses a stacking controller in a switch stacking system. Using the time synchronization method and the stacking controller described in the present invention can effectively realize the internal time synchronization of the switch stacking system, so that the switch stacking system can meet the mobile Returns the request for time synchronization.

Description

technical field [0001] The invention relates to the technical field of Ethernet switch stacking, in particular to a time synchronization method and a stacking controller in a switch stacking system. Background technique [0002] At present, Ethernet switch stacking technology can provide as many ports as possible in a limited space. Therefore, switch stacking technology is more and more used in the field of mobile communication technology, and with the continuous development of mobile communication technology, mobile services become increasingly At the same time, operators backhaul other access services and mobile services on the same network, resulting in the rapid evolution of mobile backhaul networks to IP. [0003] However, in the existing switch stacking technology, the internal time synchronization of each stacked switch is not realized, so it cannot meet the needs of mobile backhaul time synchronization, that is, it is impossible to apply the existing switch stacking ...
