Problems solved by technology

[0007] 1) Fixed type TCONT, only contains Fixed type bandwidth;
[0008] 2) Assured type TCONT, only includes Assured type bandwidth;
When long packets are transmitted when the length of the OMCI message is long, the existing OMCI bandwidth allocation technology is to allocate the aforementioned first Fixed-type bandwidth method, which will cause multiple slices of the uplink OMCI message, making the uplink OMCI message transmission time longer , and the number of buffers that need to be occupied during the uplink reorganization process increases

Embodiment Construction

[0031] Aiming at the problem that the OMCI bandwidth is assigned as Fixed bandwidth in the prior art, which inherently occupies the upstream bandwidth, resulting in low utilization of the upstream bandwidth, at the same time, in order to support better transmission of variable-length OMCI messages of XGPON, the present invention implements The example provides a device and method for dynamically allocating the bandwidth of the operation management control interface. The embodiment of the present invention is as follows: OMCI TCONT is allocated as NA type TCONT. When there is no OMCI message interaction, only the minimum bandwidth is issued. Only when the OLT and the ONU When there is an OMCI message interaction requirement, the bandwidth that can accommodate OMCI messages will be issued. When the OMCI message process ends, the OMCI message bandwidth will be recovered in time. Based on the embodiment of the present invention, good uplink bandwidth utilization and uplink OMCI mes...

Abstract

The invention provides a device for dynamically allocating bandwidth of an operation management control interface. The device comprises a software configuring module for configuring an operation management control interface transmission container OMCI TCONT as a Non-Assured type TCONT, an information configuring module for configuring the OMCI bandwidth mode and the OMCI interaction mark, and a bandwidth calculating module for calculating the OMCI bandwidth. The invention further provides a method for dynamically allocating bandwidth of the operation management control interface. By the device and the method provided by the invention, good uplink bandwidth utilization and uplink OMCI information transmission delay can be obtained.

Description

technical field [0001] The invention relates to the communication field, and relates to a device and a method for dynamically allocating bandwidth of an operation management control interface in an XGPON system. Background technique [0002] 10G-Gigabit Passive Optical Network (XGPON for short) is a communication protocol of passive optical network. XGPON adopts a point-to-multipoint topology. [0003] The OMCI operation management control interface (Optical network unit management and control interface) is a management control interface in the XGPON system, which is transmitted through the designated TCONT transmission container (Transmission container) channel. The OMCI message is encapsulated in the XGEM (XG-PON encapsulation method, XGPON encapsulation mode) frame, which is used for the OLT (Optical line terminal) to actively manage the ONU (Optical network unit), and the ONU to automatically report alarms and other information to the OLT. Such as figure 1 As shown, th...
