Description
Technical field
The application relates to communication technical field, relates in particular to a kind of method for synchronizing time and device.
Background technology
In existing communication network, the normal operation of many business all requires network clocking synchronous, be that time or difference on the frequency between each equipment of whole network remains in the rational error level, for time synchronized wherein, that usually adopts is based on PTP(Precision Time Protocol, Precision Time Protocol) time synchronized of agreement, for a pair of clock node of phase mutually synchronization, there is master slave relation, but this master slave relation is relative, below this master slave relation is done specific explanations: host node (Master Node) is the issue clock node of lock in time, clock on it is called master clock (Master Clock), otherwise, be the clock node that receives lock in time from node (Slave Node), the clock on it is called from clock (Slave Clock); For the PTP port of issuing lock in time on the clock node, usually be referred to as main (Master) port, the PTP port that receives lock in time then is called as the port from (Slave), in addition, also exist a kind of neither issue also not receive the PTP port of lock in time, be called passive (Passive) port.
Time synchronized based on the PTP agreement, its principle is: the transmitting-receiving time of synchronisation message and recording messages between the master and slave clock, calculating always coming and going between the master and slave clock by the round time difference of calculating message delays time, if network is symmetrical (transmission delay that is both direction is identical), be exactly Zong then come and go half one-way delay of time-delay, this one-way delay is the clock jitter between the master and slave clock, adjust local zone time from clock according to this deviation, just can realize itself and master clock synchronously.The PTP protocol definition two kinds of propagation delay measurement mechanisms: request-reply (Requset_Response) mechanism and end time-delay (Peer Delay) mechanism, and these two kinds of mechanism all with network to being called prerequisite.
Various message for the PTP synchronous interaction, can be according to whether needing response time stamp event to be divided into two classes, one class is that the PTP event message (comprising: synchronous (Sync) message, end time-delay request (PDelay_Req) message, time-delay request (Delay_Req) message, end delayed response (PDelay_Resp) message); One class is the non-event message of PTP (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, the PTP event message needs the response time to stab event, and this needs the support of interface board chip just can finish logging timestamp, otherwise this interface board can not be supported the PTP protocol function.
For the PTP agreement owing to need special hardware as support, so more special, below in the elaboration prior art based on the time synchronized scheme of PTP agreement.
As shown in Figure 1, for the host node of two support PTP functions with from node, in order to make the PTP time synchronized of two equipment that backup link be arranged, must respectively 4 ports all be enabled PTP, after all configurations are all configured, have following situation: 4 ports on the host node all are master port, are used for issuing time; Be from port from the port one of node, be used for from the host node device synchronization time that port 2 to 4 all is passive port, be the backup port from the port one of node, neither also asynchronous time of issuing time.
When the port one place link from node breaks down, can carry out the port role election again from node, from remaining passive port, select again one according to qualifications port as new from port, issue PTP message from port and carry out time synchronized by new then.
In the process that realizes the application, the inventor finds to exist at least in the prior art following problem:
1) owing to need be 4 member ports configuration PTP functions simultaneously, and each port all needs to carry out interacting message, and is therefore inconvenient in configuration, and can cause the very big consumption of device resource; 2) when the SLAVE port goes wrong, meeting originating port role re-elects, and causes topological structure stable inadequately.
