Dynamic Proxy Configuration for Broadband Multicast Receivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for configuring receivers to handle broadband multicast signals, particularly IPTV signals, are inflexible and require significant technical effort to change configurations, especially for dynamic adjustments or server migrations, as they often rely on fixed settings that cannot be altered at runtime without extensive intervention.
Innovation Solution
A method that dynamically configures the proxy unit within the receiver using established protocols like DHCP, RIP, or OSPF to select and adjust upstream interfaces for communication with server devices, allowing for flexible adaptation without modifying existing protocols or reconfiguring terminal devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed configuration is used for proxy unit during router setup or manufacture, then initial stability and simplicity are improved, but adaptability and ability to change configuration at runtime deteriorate
Solution Approach 1:
The patent implements dynamic configuration by allowing the proxy unit's routing table to be modified at runtime through protocol messages from the network operator. The configuration transitions from a static fixed state to a dynamic state where upstream interface assignments can be changed without physical device replacement or manual reconfiguration, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The patent changes the configuration parameters of the proxy unit dynamically by transmitting new routing table entries through standard protocols (DHCP, RIP, OSPF). This allows the network operator to modify interface assignments, IP addresses, and routing information without changing the physical device or its fundamental structure, enabling adaptability while maintaining system stability through controlled parameter updates.
2Reliability
If configuration changes are made through fixed settings or manual intervention, then reliability is improved, but ease of operation and time efficiency deteriorate
Solution Approach 1:
The patent enables self-service configuration where the proxy unit automatically receives and applies configuration updates from the network operator through standard protocols. The system performs self-reconfiguration without requiring manual intervention at the customer premises, improving ease of operation while maintaining reliability through automated, protocol-driven configuration management.
Solution Approach 2:
The patent introduces protocol messages as an intermediary mechanism between the network operator and the proxy unit. This intermediary enables remote configuration changes to be transmitted and applied automatically, eliminating the need for manual intervention while ensuring reliable configuration updates through standardized communication protocols.
3Adaptability or versatility
If protocol modification or expansion is implemented to enable dynamic configuration, then adaptability is improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent achieves dynamic configuration adaptability by utilizing existing multi-functional protocols (DHCP, RIP, OSPF) that are already widely deployed in network infrastructure. These protocols serve multiple purposes including address assignment, routing, and configuration management, eliminating the need for new specialized protocols and avoiding increased device complexity while maintaining high adaptability.
