Problems solved by technology

The processing of each business function after cascading is considered by multiple chassis at the same time. For pure business software, it is relatively simple to implement in practical applications, but the clock function needs to be implemented by hardware. In related technologies, in order to realize clock transparent transmission function, cross-chassis device cascading needs to increase hardware connections, which will lead to a certain increase in cost, and the quality of the signal will also be required to be higher due to the transmission distance, or a certain degree of accuracy will be lost

Embodiment Construction

[0028] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0029] According to the example of the present invention, a cross-frame system is provided, which realizes transparent transmission of time and frequency in cross-frame devices without increasing the hardware connection between the frame.

[0030] figure 1 is a schematic diagram of a cross-chassis system according to an embodiment of the present invention, such as figure 1 As shown, the system mainly includes: granting time frame 10 and granted time frame 20, wherein the granting time frame 10 is the frame where the clock source is located in the inter-chassis system, and the granted time frame 20 is the sub-frame in the cross-chassis system. The chassis outside the server chassis. The granting ti...

Abstract

The invention discloses a machine frame straddling system and an implementation method and device of time and frequency passthrough of the system. The method comprises the following steps: a time serviced machine frame receives information sent by a time service machine frame through a communication connecting line between the time serviced machine frame and the time service machine frame; and the time serviced machine frame acquires the time information of the time service machine frame and/or the frequency information of the time service machine frame from the received information, wherein the time serviced machine frame is a machine frame where a clock source in the machine frame straddling system is located, and the time serviced machine frame is a machine frame in the machine frame straddling system accept the time service machine frame. Through the invention, the passthrough of time and frequency in machine frame straddling equipment is realized without adding hardware connection between machine frames.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a cross-frame system and a method and device for realizing time and frequency transparent transmission thereof. Background technique [0002] In order to enhance the robustness of the device and improve the utilization rate of the device, the technology of cascading devices across chassis has been widely used in the industry. The processing of each business function after cascading is considered by multiple chassis at the same time. For pure business software, it is relatively simple to implement in practical applications, but the clock function needs to be implemented by hardware. In related technologies, in order to realize clock transparent transmission Function, cross-chassis device cascading needs to increase hardware connection, which will lead to a certain increase in cost, and the quality of the signal will be higher or lose certain accuracy due to the transmission d...
