Embodiment Construction

[0050] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0051] In the background art, the reason why PTN configures the network bandwidth value of the base station has a great waste of bandwidth resources and the allocated bandwidth resources are unbalanced: the base station of the PTN uses Table 2 to statically allocate the network bandwidth value according to the type, and there is no basis Flexible configuration of current PTN status and base station status. such as figure 1 In the ring network of the access layer, assuming that the egress is GE and the base station type of the access layer is S111 (F+D) base station, according to Table 2, the CIR value configured for this base station is 80Mb / s. The CIR value of the base station cannot exceed the CIR value of the GE outlet, namely Among them, n is ...

Abstract

The invention discloses a method and a device for determining a network bandwidth value in a packet transmission network. The invention monitors the packet service data flow of a base station in real time within a set time period, and calculates the average packet service per unit time within the set time period. Data flow, and calculate the maximum packet service data flow per unit time within the set time period; take the maximum service packet data flow among the multiple maximum packet service data flows per unit time within the set time period as the PIR value configured for the base station ; Take the half value of the average value of the average packetized service data traffic per unit time as the CIR value configured for the base station. Because the present invention uses the dynamically monitored packet service data flow of the base station when configuring the network bandwidth value, the configured network bandwidth value truly reflects the packet service data flow of the base station within the set time period, reducing the waste of PTN bandwidth resources and improving Balanced allocation of bandwidth resources.

Description

Technical field [0001] The present invention relates to the field of packet transmission networks, in particular to a method and device for determining a network bandwidth value in a packet transmission network. Background technique [0002] The packet transmission network (PTN) is a layer set between the Internet Protocol (IP) service and the underlying optical transmission medium. It is designed for the burstiness of packet service traffic and the requirements of statistical multiplexing transmission, with packet service as the core And support the provision of multiple packet services. PTN comprehensively considers the statistical distribution characteristics of packet traffic, and satisfies factors such as packet service quality and transmission efficiency. The average transmission bandwidth value is set according to the maximum rate of the PTN wireless air interface. The factors affecting the maximum rate of the PTN wireless air interface include spectrum resources, coding m...
