Embodiment Construction

[0041]Further details will be given below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as figure 2 Shown is a flow chart of a service scheduling method according to an embodiment of the present invention, which mainly includes the following steps:

[0043] Step S201, acquiring the start time stamp and end time stamp of each real-time service sending opportunity.

[0044] According to the calculation formulas of the start time scale and the end time scale, the start time scale and the end time scale of each real-time service sending opportunity are calculated.

[0045] The following is the calculation formula for the start time scale of the kth sending opportunity of the real-time service i:

[0046] S i k = S i 0 + L i max r ...

Abstract

The invention discloses a service scheduling method, which comprises the steps as follows: a beginning time scale and an ending time scale of each real time service sending chance are obtained; the beginning time scale and the ending time scale are ordered to generate a scheduling sequence; the scheduling sequence confirms an actual sending position of each real time service sending chance; and data is sent according to the scheduling sequence. The invention also discloses a service scheduling device, which improves the utilization rate of network resource and realizes the shaping and the scheduling of a variable-length packet service stream.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a service scheduling method and device. Background technique [0002] At present, the data forwarding equipment will use the queue scheduling mechanism when scheduling services at the egress. It schedules and serves different input service flows that need to be queued due to conflicts in the switching node according to certain service rules, so that all input service flows The output link bandwidth of the switching node can be shared in a predetermined manner and has QoS (Quality of Service, quality of service) guarantee. Such as figure 1 As shown, after the input traffic arrives at the switching node, it is temporarily stored in the corresponding queues. Assuming that there are a total of v queues, the task of the queue scheduling algorithm is to select the next packet to be transmitted from the v queues. [0003] According to the service rules, schedulin...
