Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. 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 arbitrarily with each other.

[0035] IEEE Std 1588 TM The -2008 protocol does not specify the use of VLAN. The main function of VLAN is to divide the broadcast domain and control the forwarding of broadcast messages. The embodiment of the present invention provides a method for determining the PTP port in combination with the VLAN ID.

[0036] The embodiment of the present invention provides a method for creating a high-precision time protocol (PTP) port, the method comprising:

Abstract

The invention provides a precision time protocol (PTP) port creation method, a boundary clock (BC) device and an ordinary clock (OC) device, wherein the precision time protocol port creation method comprises the following steps: a plurality of physical ports of a present clock device are connected with a plurality of clock devices of a same virtual local area network (VLAN) with one-to-one correspondence, and the present clock device determines that when the clock devices need a same protocol state, the present clock device creates a PTP port according to an identification of the VLAN to which the clock devices belong. According to the above PTP port creation method, the boundary clock (BC) device and the ordinary clock (OC) device, the PTP port can be created flexibly and reasonably.

Description

technical field [0001] The invention relates to communication technology, in particular to a method for creating a high-precision time protocol port, a boundary clock device and an ordinary clock device. Background technique [0002] In mobile backhaul networks, clock synchronization is a must-supported feature. The Institute of Electrical and Electronics Engineers (IEEE) 1588v2 can recover the phase and frequency of the clock. The deployment of IEEE 1588v2 in the mobile backhaul network has the following disadvantages: If all packets are sent in multicast mode, it will inevitably occupy a large amount of bandwidth in the mobile backhaul network and affect the performance of the entire network; ) nodes require the use of multicast to simplify configuration. Therefore, whether a clock synchronization port, that is, a Precision Time Protocol (PTP) port can be flexibly configured is a technical problem that needs to be solved urgently. [0003] In the prior art, the PTP port...
