Embodiment 1

[0048] Referring to Fig. 2, the bandwidth is automatically adjusted according to the predetermined time.

[0049] 1. Network management personnel formulate bandwidth adjustment strategies through the network management system.

[0050] The content of the bandwidth adjustment strategy includes: adjusting the bandwidth of service A to 2M at 12:00 midnight, and adjusting the bandwidth of service A to 10M at 7:30 am.

[0051] Then, save the bandwidth adjustment policy in Policy Manager.

[0052]2. The network management system is equipped with a control module, which monitors the current time of the system in real time. If the current time reaches 12:00 midnight, it sends a control signaling to the control plane to adjust the bandwidth of service A to 2M; if the current time is up At 7:30 in the morning, a control signaling for adjusting the bandwidth of service A to 10M is sent to the control plane.

[0053] The control module implements the functions of monitor and bandwidth c...

Embodiment 2

[0056] Referring to FIG. 3 , the bandwidth of the service is automatically adjusted according to the real-time traffic of the service.

[0057] The traffic of the business is counted, and when the traffic of the access business is small and reaches the specified limit, the bandwidth is automatically reduced to the specified value. If the traffic continues to recover and increase, the bandwidth will be automatically restored to the value agreed in advance.

[0058] The steps are:

[0059] 1. Network management personnel formulate bandwidth adjustment strategies through the network management system.

[0060] The content of the bandwidth adjustment strategy includes: when the statistical traffic of service A is 5M within 5 minutes, its bandwidth will be adjusted to 10M.

[0061] Then, save the bandwidth adjustment policy in the policy manager.

[0062] 2. The transmission equipment is provided with a service bandwidth monitoring device, which can monitor and make statistics ...

Abstract

The invention discloses a device which could automatically adjust bandwidth. A monitor is used to monitor a target and report the monitoring result. A policy manager is used to preserve adjustment policies of business bandwidth and the adjustment policies are the rules for network bandwidth adjustment. A bandwidth controller is used to read out the monitoring result and the adjustment policies. When the business bandwidth in the monitoring result meets the bandwidth adjustment condition regulated by the adjustment policies, the bandwidth controller will send out a corresponding business bandwidth adjustment order. The invention also discloses an automatic adjustment method of the bandwidth. The technical proposal of the invention can facilitate the system to perform bandwidth adjustment according to the preset policies, greatly improve intelligence degree and feasibility of ASON network and provide ASON network operation with convenience.

Description

technical field [0001] The invention relates to a communication technology, in particular to a device and an adjustment method for automatically adjusting the bandwidth of an access service in an intelligent optical network. Background technique [0002] Automatically Switched Optical Network (ASON) is an optical transport network that uses the control plane to complete automatic switching and connection control. It uses optical fiber as the physical transmission medium, Synchronous Digital Hierarchy (SDH) and Optical Transport Network (OTN) and other optical transmission systems. Intelligent optical transport network. The core of ASON network is network intelligence, including signaling, routing and automatic discovery functions to realize intelligent network control functions. [0003] The automatic switching optical network structure can be divided into three planes according to functions: transmission plane, control plane and management plane, and also includes a data c...
