Abstract

The present invention provides are a method and an apparatus for processing time synchronization. The method comprises: extending an instruction set of an OpenFlow protocol, the extended instruction set of the OpenFlow protocol being used for implementing time synchronization of a 1588 protocol; and sending a flow table configuration message to a time synchronization device, the flow table configuration message comprising the extended instruction set, and the time synchronization device implementing time synchronization according to the extended instruction set. By using the present invention, the problem in the related art is solved that time cannot be precisely synchronized by means of an OpenFlow protocol, so as to achieve the effect that the OpenFlow can support precise time synchronization and the OpenFlow application field is expanded.

Description

technical field [0001] The present invention relates to the communication field, in particular to a time synchronization processing method and device. Background technique [0002] The continuous improvement of network performance requirements makes it necessary to add many complex functions to the router architecture, for example, Open Shortest Path First (Open Shortest Path First, referred to as OSPF), Border Gateway Protocol (Border Gateway Protocol, referred to as BGP), multicast, differentiated services, traffic engineering, Network Address Translation (NAT for short), firewall, Multi-Protocol Label Switching (MPLS for short), etc. This makes switching devices such as routers more and more bloated and the space for performance improvement is getting smaller and smaller. [0003] In contrast to the predicament of the network field, the computer field has achieved rapid development. Looking back at the development of the computer field, it is not difficult to find that ...
