Hub Gateway Address Spoofing for Network Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications networks face challenges in efficiently redirecting traffic from a primary network to a secondary network during failures or degradation, particularly due to complex network topologies and the need for seamless access by all devices, which can lead to service disruptions affecting critical applications.
Innovation Solution
A method involving a Provider Hub that broadcasts unsolicited announcements to store link-layer addresses, allowing selective redirection of data packets between primary and secondary broadband networks based on predetermined criteria, enabling transparent management of traffic and network switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hub broadcasts unsolicited announcements to store link-layer addresses, then traffic redirection capability is improved, but network complexity increases
Solution Approach 1:
The hub pre-establishes link-layer address mappings through unsolicited announcements before traffic redirection is needed. This preliminary action allows the hub to have address translation capabilities ready in advance, enabling rapid traffic redirection without real-time computation or complex routing decisions when failures occur.
Solution Approach 2:
The hub acts as an intermediary device between devices and the network, intercepting and redirecting traffic based on pre-stored link-layer address mappings. This intermediary role simplifies the redirection process by centralizing the decision-making function in the hub, avoiding the need for complex coordination between multiple network devices.
2Reliability
If selective redirection of data packets is implemented based on predetermined criteria, then service integrity during failures is improved, but processing overhead increases
Solution Approach 1:
Redirection criteria and link-layer address mappings are predetermined and pre-configured in the hub before failures occur. When a network failure is detected, the hub can immediately apply these pre-established rules to redirect traffic, eliminating the need for complex real-time analysis and reducing processing overhead during critical failure scenarios.
Solution Approach 2:
The hub autonomously performs traffic redirection based on pre-configured criteria without requiring external intervention or complex coordination with other network devices. This self-service capability allows the hub to quickly respond to failures using locally stored information, minimizing processing time and maintaining service integrity.
3Adaptability or versatility
If all devices are provided with access to secondary networks, then network resilience is improved, but device coordination complexity increases
Solution Approach 1:
The hub serves as a central intermediary that manages access to secondary networks for all devices. Instead of requiring complex coordination between devices, the hub centralizes the management function by maintaining link-layer address mappings and making redirection decisions, thereby providing network resilience while simplifying device-level complexity.
Solution Approach 2:
The hub provides universal traffic redirection capability that serves all devices connected to the network. By implementing a single multi-functional redirection mechanism in the hub, the system achieves network-wide resilience without requiring individual devices to implement complex coordination protocols, as the hub handles redirection for all devices uniformly.

AI summary
Methods and systems for alternate network utilization are provided. Exemplary methods include: broadcasting by a hub an unsolicited announcement over a network to a plurality of devices coupled to a router, the unsolicited announcement being configured to cause at least some of the plurality of devices to store in a table a link-layer address of the hub as a link-layer address of the router; receiving by the hub a data packet from a device of the plurality of devices; and selectively directing by the hub the received packet to a first broadband network or a second broadband network using predetermined criteria.
