Dynamic Service Binding via DHCP Option 60
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing Triple Play services are inflexible and costly due to the need for static network planning and configuration changes when switching service providers, limiting user choice and increasing maintenance costs.
Innovation Solution
A method and device for dynamic service binding, where a terminal's service provider identifier is used to dynamically associate the user with an ISP, allowing seamless switching between providers without reconfiguring the network, utilizing DHCP Option 60 to carry ISP identification information and establish corresponding VPLS tunnels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static network planning and configuration methods are used for Triple Play services, then network structure is simplified and easy to implement, but user flexibility and service provider switching capability are severely limited
Solution Approach 1:
The patent implements dynamic binding between terminals and service providers using DHCP Option 60 to carry service provider identifiers. This allows the network configuration to adapt dynamically to user choices and service provider changes without requiring static pre-configuration for each scenario, thereby improving user flexibility while maintaining manageable network complexity through automated dynamic configuration.
Solution Approach 2:
The patent changes the binding parameter from physical location-based static configuration to service provider identifier-based dynamic binding. By using DHCP Option 60 to carry service provider identifiers and dynamically establishing VPLS tunnels based on these identifiers, the system enables flexible service provider selection and switching without requiring complex reconfiguration of network infrastructure.
2Reliability
If service provider switching is implemented through static configuration and network re-planning, then service binding is reliable and stable, but operation and maintenance costs increase significantly
Solution Approach 1:
The patent enables terminals to automatically identify and bind to service providers through DHCP Option 60 carrying service provider identifiers. This self-service mechanism eliminates the need for manual network reconfiguration and service provider switching operations, thereby maintaining reliable service binding while significantly reducing operation and maintenance costs through automated terminal-side service provider selection and binding.
3Productivity
If multiple terminals share the same port, VLAN, or tunnel for accessing different ISPs, then network resource utilization is improved, but service isolation and user choice are compromised
Solution Approach 1:
The patent segments the network binding at the service provider identifier level rather than at the physical terminal level. Each terminal can independently identify and bind to different service providers through DHCP Option 60, creating logical segmentation that maintains network resource sharing while enabling independent service provider selection for each terminal, thus preserving both resource utilization efficiency and service selection flexibility.
Solution Approach 2:
The patent introduces DHCP Option 60 as an intermediary mechanism that carries service provider identifiers between terminals and the network. This intermediary enables multiple terminals to share network infrastructure resources while maintaining independent service provider bindings, effectively decoupling resource sharing from service provider association and allowing both goals to be achieved simultaneously.

AI summary
A method for service binding includes: identifying a service provider identifier of a terminal and binding the terminal into a corresponding tunnel dependent upon the identified service provider identifier. The present invention implements dynamic binding of a terminal with a service through identifying a service provider identifier of the terminal, which offers more flexible selection of a service by a user, a reduced operation and maintenance cost of an operator, good extensibility of a network service and facilitated deployment of the service.
