Virtual Slot Allocation for Value-Added Service Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current value-added service deployment methods in communications networks lead to resource wastage and inflexible service extension due to the need for dedicated devices and complex policy-based routing configurations.
Innovation Solution
A method where a network device receives a registration request from a value-added service device, acquires virtual system information, allocates a virtual slot and slot number, and manages the virtual system as a value-added service board, enabling on-demand deployment and flexible extension of services through a bidirectional extended GRE tunnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent value-added service devices are deployed in each location according to maximum capacity, then service reliability is improved, but device resource waste increases
Solution Approach 1:
The patent implements a shared value-added service device architecture where a single device can serve multiple network locations simultaneously. The device receives service flows from different locations through a switching network, allowing one physical device to perform value-added services for multiple locations, thereby eliminating the need for separate devices at each location and reducing overall device resource consumption while maintaining service reliability
Solution Approach 2:
The patent merges multiple independent value-added service devices into a single shared device. By combining the functionality of multiple devices into one unified system with a shared processing platform and switching network, the patent achieves resource consolidation that reduces device waste while preserving the service capabilities needed for reliable operation across multiple locations
2Loss of substance
If value-added service devices are deployed in bypass mode on network devices, then device resource usage is improved, but configuration complexity increases
Solution Approach 1:
The patent introduces a switching network as an intermediary component between the value-added service device and multiple network locations. This switching network simplifies the architecture by providing a standardized interface and automatic flow distribution mechanism, eliminating the need for complex policy-based routing configurations on individual network devices while maintaining efficient resource utilization through bypass-mode deployment
3Ease of operation
If dedicated value-added service boards are inserted into network devices, then configuration burden is reduced, but service extension flexibility is limited
Solution Approach 1:
The patent creates a universal value-added service platform that can dynamically provide multiple types of services (firewall, load balancing, intrusion prevention, data loss prevention, anti-virus, application acceleration) through a single shared device. This universal architecture allows services to be extended and added flexibly without requiring dedicated physical boards for each service type, as the shared device can allocate resources dynamically to support various service functions
Data Source
AI summary
A value-added service deployment method, a network device, and a value-added service device, which relates to the field of network communications. The network device receives a first registration request message sent by the value-added service device, where the first registration request message includes an Internet Protocol (IP) address of the value-added service device, where the network device acquires virtual system information of a virtual system generated by the value-added service device for the network device according to the first registration request message, the network device allocates a virtual slot and a slot number to the virtual system and sends the slot number to the virtual system according to the virtual system information, and the network device manages the virtual system as a value-added service board of the network device.
