Problems solved by technology

[0003] The current ONU slice management often needs to be manually arranged through the resource network management, and the ONU slices are divided uniformly. The management workload is heavy, the configuration efficiency is low, and the slice network cannot support the dynamic changes of ONU joining and migration.

Embodiment 1

[0059] The object of the present invention is to solve the above problems, and provide a dynamic slice management method based on network auto-negotiation. According to the two-way network negotiation between the ONU and the OLT, the method can automatically complete the network management and maintenance of the dynamic slice of member joining and member migration of the slice network. Such as figure 1 As shown, the present invention provides a method for implementing network slice management at the OLT, including:

[0060] S1. Perform slice configuration information. The slice configuration information includes: slice ID, slice function attribute definition, slice resource range, limit on the number of ONUs under the slice, online number of ONUs under the slice, traffic limit under the slice, peak value under the slice Entity ONU capability model under traffic and slice;

[0061] Specifically, the slice configuration information is defined as:

[0062] The slice ID is used...

Embodiment 2

[0072] Such as figure 2 As shown, it is a schematic flow diagram of ONU joining in the embodiment of the present invention. According to the following scheme, OLT and ONU are allowed to negotiate network slices and dynamically manage slice resources, including:

[0073] When the ONU registers online in the OLT, the ONU and the OLT send the ONU slice configuration notification message (VS_ONU_NOTIFY) through the OAM (Operation Administration and Maintenance)\OMCI (ONU Management and Control Interface, Optical Network Unit Management Control Interface) protocol With the OLT slice configuration notification message (VS_OLT_NOTIFY), the two parties perform the notification interaction of the slice configuration information of the OLT and the slice status information of the ONU:

[0074] The OLT slice configuration notification message (VS_OLT_NOTIFY) includes the slice configuration information of the OLT, specifically: slice ID, slice function attribute definition, slice resourc...

Embodiment 3

[0083] Such as image 3 As shown, it is a schematic flow diagram of the ONU side initiating slice migration in the embodiment of the present invention. According to the following scheme, the ONU locally initiates the migration of the slice network to the OLT, including:

[0084] The ONU side actively initiates the slice configuration notification message, and the ONU and the OLT send the ONU slice configuration notification message (VS_ONU_NOTIFY) and the OLT slice configuration notification message (VS_OLT_NOTIFY) through the OAM\OMCI protocol, and the two parties exchange the slice configuration information of the OLT and the slice status information of the ONU. notification interaction;

[0085] The ONU side can actively apply for slice migration from the OLT side, and send an ONU slice migration request message (VS_ONU_SW) to the OLT through the OAM\OMCI protocol. The content of the ONU slice migration request message includes: ONU ID, current slice ID, application migrati...

Abstract

The invention discloses a dynamic slice management method based on network auto-negotiation. The method comprises the following steps that: slice configuration information of each slice is configured,wherein the slice configuration information comprises a slice ID, a slice function attribute definition, a slice resource range, an ONU number limit under the slice, the number of online ONUs under the slice, a flow limit under the slice, a peak flow under the slice and an entity ONU capability model under the slice; and notification interaction of slice configuration information of OLTs and slice state information of the ONUs is achieved by configuring a notification message, and ONU joining or migration operation is executed according to the slice configuration information of the OLTs and the slice state information of the ONUs so as to dynamically manage slice resources. According to the method of the invention, the ONUs of the same type and the same functional performance can be dynamically collected to the same slice according to the ONU capability model of the slice, the number of the ONUs of the slice and the configuration attribute of the slice, and automatic arrangement and management of the slice are realized. The invention further provides a corresponding dynamic slice management device based on network auto-negotiation.

Description

technical field [0001] The present invention belongs to the technical field of communication, and more specifically relates to a dynamic slice management method and device based on network auto-negotiation. Background technique [0002] With the continuous improvement of people's demand for broadband services, the continuous emergence of broadband applications such as high-speed Internet, interactive TV, 3D high-definition video, cloud computing, cloud storage, and the Internet of Things has caused the bandwidth demand of transmission networks to double from the backbone to the metropolitan area network. . At the same time, with the continuous development and updating of communication technology, broadband services are also developing in the direction of integration, digitalization, intelligence, and virtualization. OLT (Optical Line Terminal, Optical Line Terminal) is a PON (Passive Optical Network, Passive Optical Network) system It is responsible for the comprehensive ac...
