Problems solved by technology

[0004] At present, PTN mainly relies on the network management system to configure QoS services through manual service arrangement and manual configuration. However, because SPTN equipment is still in the research and development and promotion stage, the QoS service configuration of SPTN equipment has not yet formed a unified configuration and delivery specification. The OpenFlow protocol It is also impossible to implement the controller's deployment of QoS in the packet transport network SPTN equipment

Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0043] see figure 1 As shown, the embodiment of the present invention provides a method for realizing the QoS function on the SPTN equipment, and the specific steps are as follows:

[0044] S1. The user configures the QoS service configuration data on the northbound interface of the SDN. The configuration data includes the priority identification of the QoS service, the guaranteed throughput rate and the maximum allowable rate, as well as queue scheduling and congestion policies. The queue scheduling and congestion policies are used for traffic scheduling. And / or traffic shaping and / or traffic congestion packet loss operations, and determine the data packets of the switch to output, cache, or discard from the specified interface.

[0045] S2. The controller generates ingress and egress flow mod messages according to the priority identificatio...

Abstract

The invention discloses a method and system for realizing QoS function on SPTN device. The method comprises the following steps: S1, a user configures configuration data of QoS service in a northern interface, wherein the configuration data comprise a priority identifier, a guaranteed pass rate and a maximum allowable rate of the QoS service, and a queue scheduling and congestion strategy; S2, a controller generates a flowmod message of an inlet and an outlet and issues the flowmod message through an openflow protocol, the controller generates a metermod message and issues the metermod message through the openflow protocol, and the controller generates an of-config message and issues the of-config message through an netconf protocol; and S3, a driving module of an SPTN devices receives the flowmod message of the inlet and the outlet, the metermod message and the of-config message, and performs corresponding configuration according to the flowmod message, the flowmod message of the outlet, the metermod message and the of-config message so as to issue the service.

Description

technical field [0001] The invention relates to the technical fields of optical communication, optical interconnection and optical information transmission, in particular to a method and system for realizing QoS function on SPTN equipment. Background technique [0002] Software-defined network (Software Design Network, SDN) is a new network architecture that optimizes and simplifies network operations. It separates the control and forwarding planes of the network, and at the same time places the intelligent control plane in a centralized manner, improving the convenience of the network. , flexibility and innovation. At present, under the impact of SDN technology, PTN (Packet Transport Network) equipment ushered in a new generation of SPTN (Software Defined PacketTransport Network) technology, which aims to solve the traditional PTN equipment variety, business change difficulties, The disadvantages of high maintenance cost and low efficiency are realized by using a unified c...
