Transparent Network Security Management Without Device IP Addresses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network security devices without IP addresses, when transparently connected, cannot achieve normal connection and communication and cannot be managed remotely, leading to increased workload and costs due to the need for a separate management network.
Innovation Solution
A method and apparatus for managing network devices without addresses by recognizing an initiator terminal's address, constructing a standard UDP/TCP data packet with session state information, and sending it to a management server, allowing for configuration updates and security policy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a network security device is transparently connected to a network without IP addresses, then the network topological structure remains unchanged and renovation costs are reduced, but the device cannot achieve normal connection and remote management
Solution Approach 1:
The patent introduces a dedicated management network as an intermediary channel between the transparent network security device and the management system. This separate management network uses remaining interfaces of the security device to establish a dedicated communication path, enabling remote management while keeping the transparent connection intact. The management network acts as a mediator that resolves the conflict between transparent operation and manageability.
2Ease of operation
If a dedicated management network is created separately for managing transparent network security devices, then remote management capability is achieved, but the workload and investment costs increase
Solution Approach 1:
The patent makes the remaining interfaces of the network security device serve multiple functions: they continue to support transparent network security functions while simultaneously providing management capabilities through the dedicated management network. This multi-functionality approach allows the same hardware resources to fulfill both security and management roles, reducing the need for additional dedicated management hardware and lowering overall system complexity.
3Reliability
If network security devices are transparently connected without IP addresses, then network connectivity is maintained, but the devices cannot be directly managed or maintained
Solution Approach 1:
The patent segments the network functions into two distinct parts: the transparent data plane that maintains network connectivity without IP addresses, and the dedicated management plane that handles device maintenance and management. By separating these functions into different communication channels, the system preserves network connectivity while enabling maintenance capabilities through the management network using remaining interfaces.

AI summary
The present disclosure discloses an operation management method for a network device without address information, which includes: recognizing an address of a front-end terminal; constructing a standard UDP/TCP data packet according to the address and session state information; and sending the standard UDP/TCP data packet. In another aspect, a network device without address information is claimed, which includes: a recognizing module configured to recognize an address of a front-end terminal; a data packet generating module configured to construct a standard UDP/TCP data packet according to the address and session state information; and a sending module configured to send the standard UDP/TCP data packet. The method and device described above can reduce the workload of network renovation while minimizing renovation costs, thereby maximizing cost effectiveness. Thus, any technical breakthrough in this direction is regarded as the direction of development.
