A method and device for calculating service delay

Abstract

The embodiment of the invention provides a method and apparatus for calculating a service delay, and relates to the field of communication. The delay of the service can be accurately reflected. The method comprises the following steps: determining, by a computing device, the number N of all multiplexing sections in an ROADM network, wherein N is an integer greater than 2; determining, by the computing device, N services; for the first service and the second service in the N services, at least one multiplexing section corresponding to the first service is not exactly the same as the at least one multiplexing section corresponding to the second service, and the first service and the second service are any two services of the N services; and determining, by the computing device, the delay ofeach multiplexing section in all multiplexing sections according to the delays corresponding to the N services and the multiplexing sections corresponding to the N services. The method and apparatus provided by the invention are applied to the ROADM network.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for calculating service delay. Background technique [0002] All-optical network means that the network transmission and switching processes are all realized through optical fibers, without the need for electro-optical and photoelectric conversion, so the network speed can be greatly improved. In an important stage of development of the all-optical network, a reconfigurable optical add-drop multiplexer (Reconfigurable Optical Add-Drop Multiplexer, ROADM) needs to be introduced in the switching layer. The ROADM network has flexible scheduling and service management capabilities, which can eliminate the bandwidth bottleneck of electrical equipment, realize network transparency, simplify and speed up the assignment of high-speed circuits and service provision, and reduce network construction costs and operation and maintenance costs. [0003] Before the s...

[0004] However, according to the minimum number of hops and the shortest optical fiber distance of the service, it can only reflect the propagation delay caused by the transmission of the service in the optical fiber, and cannot reflect the processing delay, serial delay and storage delay of the service. The proportion of delay is related to the rate of business and the performance of equipment
