Dynamic DHCP Service Redirection via IP Pool Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed data service access is often expensive and not independent of media delivery mechanisms, limiting affordable internet access for residential and business users.
Innovation Solution
A system for event-driven redirection of Internet protocol (IP) service flows using a DHCP server with a processing device that provides new IP addresses and DNS servers to redirect network traffic based on MAC addresses, enabling content-triggered high-speed data service delivery independent of media delivery mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional DHCP lease mechanisms are used, then network stability is maintained, but service redirection capability is limited
Solution Approach 1:
The patent applies dynamics by making the DHCP server's lease provision dynamic rather than static. The server can now provide different IP addresses from different pools based on real-time service requirements, transforming a traditionally static DHCP function into a dynamic service redirection mechanism that adapts to changing network conditions and service demands.
Solution Approach 2:
The DHCP server is enhanced to perform multiple functions: traditional IP address assignment, service-specific IP provisioning, and automated service redirection. By making the DHCP server universal, the patent eliminates the need for separate specialized systems while achieving service redirection capability through intelligent IP address management and service tag tracking.
2Adaptability or versatility
If service-specific IP addresses are provided through DHCP, then service redirection is enabled, but network infrastructure complexity increases
Solution Approach 1:
The existing DHCP server and gateway are enhanced to perform service redirection functions without introducing entirely new infrastructure components. The DHCP server manages multiple IP pools and service tags, while the gateway uses DNS-based redirection, making the existing infrastructure universal and multi-functional rather than requiring dedicated redirection hardware.
Solution Approach 2:
The patent introduces DNS as an intermediary mechanism for service redirection. Instead of requiring complex routing changes or specialized redirection hardware, the system uses DNS name resolution as a mediator to redirect service traffic. This intermediary approach leverages an existing network component to achieve redirection with minimal additional complexity.
3Ease of operation
If content-triggered service delivery is implemented, then affordable internet access is enabled, but service control complexity increases
Solution Approach 1:
The system implements self-service by automatically matching user service tags with available service pools based on content consumption events. When a user consumes advertised content, the system automatically provisions appropriate service without manual intervention. This self-service automation reduces operational complexity despite the sophisticated service control logic required.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors service tag assignments, IP address usage, and service delivery outcomes. This feedback loop enables automatic adjustment of service provisioning and redirection, allowing the system to maintain affordable access models while managing service control complexity through continuous optimization rather than static complex configurations.
Data Source
AI summary
A system provides for event-driven redirection of IP service flows and receives an add event that triggers revectoring of all network traffic that use an Internet gateway that directs all network traffic to unfettered Internet access; provides a new lease for a specified address; transmits, to the Internet gateway, new instructions; the Internet gateway redirects all network traffic originating from the Internet gateway to a specified destination corresponding to an advertisement content server that presents a predetermined amount of advertisement content; receives a remove event corresponding to the specified address; provides a new lease for the specified address; and transmits second new instructions corresponding to values existing prior to the redirection of all network traffic to the specified destination, thereby directing all of the network traffic originating from the Internet gateway back to unfettered Internet access.
