Solution Overview

Problem

The existing service parameter configuration method for a large number of optical node devices in a D-CCAP is inefficient, leading to a long configuration time and low efficiency due to the need for individual configuration by the EMS.

Innovation Solution

The method involves determining service configuration parameters for sets of optical node devices based on service types or areas, encapsulating these parameters into IP packets, and sending them to a forwarding device, which then distributes them to the respective optical node devices through identified target ports, allowing shared configuration parameters and reducing the number of configuration times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the EMS performs service parameter configuration for each optical node device individually by encapsulating parameters into separate IP packets, then each device receives its configuration, but the quantity of configuration times increases and configuration efficiency decreases

Engineering Contradiction:
Improveservice parameter configuration efficiencyVSAvoidconfiguration time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent merges service parameter configurations for multiple optical node devices into a single IP packet. Instead of creating separate IP packets for each device, the system consolidates configurations into one packet that contains service configuration parameters for multiple devices, thereby reducing the number of configuration operations and improving efficiency

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The IP packet is designed to serve multiple optical node devices simultaneously by including service configuration parameters for multiple devices within a single packet structure. This multi-functional approach allows one IP packet to perform the configuration task that previously required multiple separate packets

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If an independent IP address is configured for each optical node device, then individual device addressing is enabled, but IP address resources are consumed for a large quantity of devices

Engineering Contradiction:
Improvedevice addressing capabilityVSAvoidIP address resources
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent combines multiple optical node device configurations into a single IP packet addressed to one destination IP address (the forwarding device). This merging approach reduces IP address consumption by eliminating the need for the EMS to individually address and send packets to each optical node device

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The forwarding device acts as an intermediary that receives the consolidated IP packet from the EMS and then distributes the service configuration parameters to the appropriate optical node devices. This intermediary approach allows the system to maintain individual device addressing capability while reducing overall IP address resource consumption at the EMS level

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

This application provides a service parameter configuration method based on a D-CCAP, and an apparatus, to resolve a prior-art problem of relatively low efficiency in service parameter configuration performed by an EMS for a large quantity of optical node devices. The method includes: determining, by an EMS, a service configuration parameter for an optical node device set, where the optical node device set includes at least one optical node device; and sending the service configuration parameter for the optical node device set to a forwarding device, so that the forwarding device sends the service configuration parameter to each of the at least one optical node device. In the method, the at least one optical node device in the optical node device set may share a service configuration parameter. In this way, the EMS does not need to perform service parameter configuration for all of the large quantity of optical node devices one by one, thereby reducing a quantity of service parameter configuration times, shortening a consumed time, and improving service parameter configuration efficiency.
