Problems solved by technology

However, after the introduction of POTN, there are still some problems in the network system, that is, it is difficult to group and aggregate services with many types and complex characteristics, resulting in waste of bandwidth resources and delay in processing some services with high delay requirements.

specific Embodiment

[0093] Power grid transmission business can be divided into marketing business, production business, management business, automatic business, switching business, etc. according to business characteristics. These different services are given different characteristic values, and when the business flows into the system, the system will compare the correlation between the incoming business and the characteristic values ​​of each business. When an incoming service matches a certain characteristic service, the service is classified into the service group. When the business is grouped, each group calculates the priority weight factor of the business group according to the business in it and sorts it. After the sorting is completed, reordering is performed according to the group weighted fair scheduling algorithm, in order to reduce the excessive accumulation of high-priority services, thereby avoiding the possible result that low-priority services are difficult to be processed.

Abstract

The invention discloses a power grid service transmission method and system. The method comprises the following steps: determining characteristic values of various types of services in a power grid system; performing primary division on the service according to the characteristic value to obtain a plurality of service groups; sorting the plurality of service groups; counting the weight factors of the sorted service groups and determining a priority threshold value; adjusting the priority order of the service group according to the priority threshold; obtaining the value of services in each service group after the priority sequence is adjusted; packaging services in each service group to a channel according to the comprehensive value and the network condition, wherein the sum of bandwidths packaged to the channel is smaller than a channel bandwidth limit value; judging whether the residual capacity in the communication pipeline is smaller than the minimum bandwidth value of the residual service or not; and if yes, expanding the communication pipeline. According to the method, the priority and the fairness are considered, the channel resource waste can be remarkably reduced while all services are ensured to be transmitted, and the channel utilization rate is improved.

Description

technical field [0001] The invention relates to the field of optical networks, in particular to a power grid service transmission method and system. Background technique [0002] In the optical network technology, the Packet Enhanced Optical Transport Network POTN (Packet Enhanced Optical Transport Network, Packet Enhanced Optical Transport Network), which combines the packet transport network PTN and the optical transport network OTN, is applied to the power grid transmission system. Due to the wide variety of services in the power grid transmission system, and the size and granularity of each service, delay requirements, value, and waiting degree, it is difficult to meet the needs of power broadband communications using traditional synchronous digital systems, optical transport networks and other technologies. The packet-enhanced optical transport network technology is suitable for the design and construction of the backbone layer of the power communication network. Howev...
