Embodiment
For the purpose that makes the embodiment of the invention, technical scheme, and advantage clearer, below the technical scheme that the embodiment of the invention provides is elaborated with reference to accompanying drawing.
The switching network of multiple planes global timing mark synchronization method that the embodiment of the invention provides comprises: receive the cipher chain synchronization that overall markers discharge device sends; Send cipher chain synchronization to flow management apparatus by the equipment room link, synchronous described flow management apparatus.
More than the method that provides for the embodiment of the invention, the overall markers simultaneous operation of entire switching network is triggered by overall markers discharge device in the method, because cipher chain synchronization is by the equipment room link, be sent to flow management apparatus in the switching network of multiple planes, and the link that the equipment room link makes up when being the switching network of multiple planes networking, therefore, the technical scheme that provides of the embodiment of the invention can not increase the design cost of switching network.
Below in the practical application, the embodiment of the invention provides the specific implementation process of method to describe in detail.
See also Fig. 2, for the switching network of multiple planes overall situation markers synchro system that first embodiment of the invention provides is formed schematic diagram, this system comprises: overall markers discharge device and switching network equipment, switching network equipment comprises: TM201, the S1/3 crosspoint 20K2 that reaches the first order and the S2 crosspoint 20K3 of intergrade, wherein, K represents the sequence number on plane, described crosspoint place, such as, S1/3 crosspoint 2011 is the S1/3 crosspoints that are on switching network of multiple planes first plane.Square frame maximum among Fig. 2 is represented a plane, and each TM evenly is distributed to each plane with the flow of oneself.
In order to strengthen the synchronous reliability of overall markers, the overall markers discharge device that the embodiment of the invention provides comprises: main overall markers discharge device and standby overall markers discharge device.
In actual applications, can select in TM, S1/3 crosspoint, the S2 crosspoint any one, trigger the synchronous flow process of overall markers as overall markers discharge device.
At first, be example with the S2 crosspoint as overall markers discharge device, the switching network of multiple planes global timing mark synchronization method that the embodiment of the invention is provided describes in detail.
See also Fig. 3, be the switching network of multiple planes global timing mark synchronization method flow chart that first embodiment of the invention provides, by the main overall markers discharge device of any one S2 crosspoint 2013 ' conduct in first plane, this method comprises in this embodiment:
Step 301:S2 crosspoint 2013 ' is designated as benchmark during with this locality, and cycle or aperiodicity send the cipher chain synchronization that carries self markers and path delay parameter to coupled all or part S1/3 crosspoint 2012 wherein;
In embodiments of the present invention, cipher chain synchronization all is to be sent to the switching network equipment that each links to each other by the equipment room link, repeats no more.
Because cell transmits on the path and has delay, synchronous in order to realize overall accurately markers, also carried path delay parameter parameter in the cipher chain synchronization, the error that causes with the path delay parameter that remedies between switching network equipment, wherein the transmission delay size of path delay parametric representation cell on the path.
In actual applications, configuration path delay parameter in the following ways:
1, the wire length calculating path delay parameter between each switching network equipment that obtains according to manual measurement configuration, with the path delay parameter configuration in corresponding switching network equipment;
2, the transmit path delay parameter is measured cell, and this path delay parameter measurement cell is exclusively used in the path delay parameter of measuring between switching network equipment, and the path delay parameter that measures is kept in the corresponding switching network equipment.
It should be noted that in actual applications, to the less demanding occasion of markers synchronous accuracy, also can not carry path delay in the cipher chain synchronization, do not influence the realization of the embodiment of the invention at some.
Step 302:S1/3 crosspoint 2012 upgrades self markers according to markers and path delay parameter that described cipher chain synchronization carries;
