Described cluster route system includes main Main subrack router and at least two business frame router, with reference to Fig. 1
And Fig. 2, in one embodiment, this clock synchronizing method includes:
Step S10, the configuration data that described main Main subrack router inputs according to user arrange clock source, institute
Stating clock source is main Main subrack router or business frame router；
The clock synchronizing method that the present embodiment provides is applied in the clock synchronization of cluster route system, passes through
Main Main subrack router in cluster route system and each business frame router are carried out clock synchronization, and
Under the coordination of main Main subrack router, each business frame router can cooperate, parallel processing, as
Same router is in work, thus realizes the lifting of bandwidth upgrading and disposal ability.It should be noted that,
Clock synchronizes to include two aspect synchronizing informations, is on the one hand Phase synchronization, i.e. deviation correction time, another
Aspect is Frequency Synchronization, i.e. correction frequency speed.
Specifically, user can be in the appointment interface of main Main subrack router input configuration data, for master
The configuration data that Main subrack router inputs according to user arrange clock source；Described clock source can be in master
Heart frame router or business frame router.Such as, arbitrary in user can arrange this cluster route system
Business frame router is clock source, for main Main subrack router when this business frame router obtains synchronization
Clock information.
Step S20, described main Main subrack router obtains synchronised clock information preset in described clock source,
Described synchronised clock information includes frequency synchronization information and phase synchronization information；
Step S30, described main Main subrack router is according to the type of described clock source, by described synchronised clock
Information sends to corresponding router, carries out clock synchronization for each router.
Owing to, in cluster route system, main Main subrack router is responsible for coordinating and managing each business frame router,
Business frame router is responsible for the router basic services such as message forwarding, it is to be understood that in the present embodiment,
After main Main subrack router gets synchronised clock information, main Main subrack router it is responsible for synchronised clock
The distribution of information.
Specifically, main Main subrack router can be configured so that clock source, business frame router also can be set
It is set to clock source.
When business frame router is arranged to clock source, above-mentioned steps S30 is particularly as follows: described main center
Described synchronised clock information is issued to be arranged to outside the business frame router of clock source by frame router
All-router.
When main Main subrack router is arranged to clock source, above-mentioned steps S30 is particularly as follows: main Main subrack
Described synchronised clock information is issued to the all-router outside main Main subrack router by router.
It is understood that receive described synchronised clock information router will according to described synchronize time
Self clock of clock synchronizing information.
When the embodiment of the present invention is arranged according to the configuration data that user inputs by described main Main subrack router
Zhong Yuan, described clock source is main Main subrack router or business frame router；Described main Main subrack router
