Embodiment Construction

[0063] First, the network architecture involved in the embodiment of the present application is introduced.

[0064] With the development trend of NFV, the access cloud network is transformed from a traditional pure analog digital communication system to a software-defined radio system (that is, the network architecture composed of traditional physical structures is transformed into the network architecture of NFV). figure 1 A schematic diagram of a network architecture for accessing a cloud network provided by an embodiment of the present application. Such as figure 1 As shown, the entire radio function will be run in the processing unit (Baseband Unit, BBU) pool, for example, the central processing unit (Central Processing Unit, CPU) and other computing resources, baseband signal transmitters, etc. are integrated in the processing unit pool; Analog to Digital (AD) / Digital to Analog (DA) conversion, power amplifiers, antennas, etc. will be implemented on the distributed Remo...

Abstract

The embodiment of the application provides a data packet scheduling method and device. The method includes the following steps: executing a first judgement operation, wherein the first judgement operation includes: determining whether a ratio of a worst case execution time (WCET) corresponding to a first service data packet of first user equipment to be scheduled in a current scheduling period toa relative cut-off time is greater than a preset value; if the ratio is greater than the preset value, abandoning the scheduling of the first service data packet, taking a second service data packetof second user equipment to be scheduled as a new first service data packet, and returning to execute the first judgement operation until the ratio of the WCET corresponding to the new first service data packet to the relative cut-off time is not greater than the preset value, and scheduling the new first service data packet. Thereby, compared with scheduling algorithms in the prior art, a high utilization rate of the scheduling processing capability of the data packet scheduling device can be realized in the data packet scheduling method provided by the embodiment.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a data packet scheduling method and device. Background technique [0002] With the development of the communication system, the network architecture of the communication system also changes. For example, the network architecture composed of traditional physical structures is transformed into a network function virtualization (Network Function Virtualization, NFV) network structure. Therefore, research on scheduling algorithms that can be applied to new network structures is a very important research direction at present. [0003] In a traditional network structure, when receiving scheduling requests sent by multiple user equipments (wherein, the scheduling request of any user equipment carries the service data packet of the user equipment), the network equipment according to the preset policy (such as short service priority etc.) to prioritize the service ...
