Embodiment Construction
[0018] The technical solutions of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] This embodiment provides a method for managing VOQ authorization surplus. In this embodiment, the managed VOQ can be system-level VOQ, port-level VOQ, user-level VOQ or queue-level VOQ, so that VOQ authorization surplus management with different precision can be realized. In order to solve the problem that the method for managing VOQ authorized surplus in the prior art cannot make good use of data packet transmission bandwidth resources, the solution of this embodiment needs to determine a ratio of VOQ authorized surplus cleared, the managed VOQ Authorized surplus clearance coefficient, the authorized surplus clearance coefficient is determined according to the authorization assigned to the managed VOQ and the input traffic of the managed VOQ, the authorization assigned to the VOQ is used to indicate the amount of d...

The present invention relates to the technical field of communications, and provides a method and device for managing Virtual Output Queue (VOQ) authorization surplus so as to solve the problem that the method for managing VOQ authorization surplus in the prior art is unable to utilize data packets to transmit bandwidth resources well. The method includes: determining an authorization surplus removal coefficient of the VOQ according to the authorization allocated to the VOQ being managed and the input traffic of the VOQ, wherein the authorization allocated to the VOQ is used for expressing the de-queue amount of the data packet, and the authorization surplus removal coefficient is used for expressing the proportion of the authorization surplus of the VOQ to be removed, and updating the authorization surplus of the VOQ according to the authorization surplus removal coefficient if the authorization surplus removal coefficient is not zero. In the present invention, the authorization surplus removal coefficient is determined according to the allocated authorization and the input traffic and the authorization surplus is updated, so that the data packets can be utilized better to transmit bandwidth resources.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for managing the authorized surplus of a virtual output queue. Background technique [0002] The basic unit of packet transmission network operation is the data packet, and the size of the data packet has a large dynamic range, ranging from dozens of bytes to thousands of bytes. An excellent packet transmission network needs to be able to provide rich and differentiated services, so complex traffic management mechanisms are commonly used in packet transmission network devices. There are two common scheduling mechanisms: [0003] The first is a data-driven scheduling mechanism, and only after the data packet arrives at the scheduling node, the corresponding scheduling is performed. The input side schedules the user's traffic and transmits it to the output side, and the output side schedules the output. The scheduling mechanism is simple to configure, ...
