Description
Technical field
The application relates to communication technical field, particularly relates to a kind of method for synchronizing time and device.
Background technology
In existing communication network, permitted multiple services normal operation and all required clock synchronization of ad, namely the time between each equipment of whole network or difference on the frequency remain in rational error level, for time synchronized wherein, usual employing be based on PTP(PrecisionTimeProtocol, Precision Time Protocol) time synchronized of agreement, for a pair clock node of phase mutually synchronization, there is master slave relation, but this master slave relation is relative, specific explanations is done to this master slave relation below: host node (MasterNode) is the clock node issuing lock in time, clock on it is called master clock (MasterClock), otherwise, it is the clock node receiving lock in time from node (SlaveNode), clock on it is called from clock (SlaveClock), for PTP port clock node being issued lock in time, usually main (Master) port is referred to as, the PTP port receiving lock in time is then called as from (Slave) port, in addition, also exist and a kind ofly neither issue the PTP port also not receiving lock in time, be called passive (Passive) port.
Based on the time synchronized of PTP protocol, its principle is: synchronisation message between master and slave clock the transmitting-receiving time of recording messages, the time difference come and gone by calculating message calculates the round total time delay between master and slave clock, if network is symmetrical (namely the transmission delay of both direction is identical), be exactly total then come and go the half one-way delay of time delay, this one-way delay is the clock jitter between master and slave clock, adjust local zone time from clock according to this deviation, just can realize its synchronous with master clock.PTP protocol defines two kinds of propagation delay measurement mechanisms: request-reply (Requset_Response) mechanism and end time delay (PeerDelay) mechanism, and these two kinds of mechanism are all premised on network symmetry.
For the various message of PTP synchronous interaction, two classes can be divided into according to the need of response time stamp event, one class is that PTP event message (comprising: synchronous (Sync) message, end latency request (PDelay_Req) message, latency request (Delay_Req) message, end delayed response (PDelay_Resp) message); One class is PTP non-event message (comprising: declaration (Announce) message, follow-up (Follow_Up) message, delayed response (Delay_Resp) message, end delayed response follow-up (PDelay_Resp_Follow_Up) message); Wherein, PTP event message needs the response time to stab event, and this needs the support of interface board chip just can complete logging timestamp, otherwise this interface board can not support PTP protocol function.
For PTP protocol, because needs special hardware is as support, so more special, set forth the Time Synchronizing based on PTP protocol in prior art below.
As shown in Figure 1, for the host node of two support PTP functions with from node, backup link is had in order to make the PTP time synchronized of two equipment, must respectively by 4 all enable PTP of port, after all configurations are all configured, have following situation: 4 ports on host node are all master port, for issuing time; Be from port from the port one of node, for from host node device lock in time, port 2 to 4 is all passive port, is the backup port of the port one from node, neither the issuing time also asynchronous time.
When from the port one place link failure of node, port role election can be re-started from node, again select from remaining passive port one preferentially port as new from port, then issue PTP message from port carry out time synchronized by new.
In the process realizing the application, inventor finds at least there is following problem in prior art:
1) because needs are 4 member port configuration PTP functions simultaneously, and each port needs to carry out interacting message, therefore, inconvenient in configuration, and can cause the very big consumption of device resource; 2) when SLAVE port goes wrong, meeting originating port role re-elects, and causes topological structure stable not.
