Transport Intermediation Server Packet Delivery Policy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems face challenges in managing packet delivery efficiently, particularly in ensuring secure and authorized transmission of messages between devices, as intermediation servers cannot decrypt encrypted payloads and lack effective filtering mechanisms to prevent unwanted messages.
Innovation Solution
The method involves receiving messages at transport intermediation servers with unique encryption mechanisms, extracting origination and destination identifiers, and applying delivery policies to forward messages only from permitted senders, using techniques like whitelisting and encryption to secure packet delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption mechanisms are used to secure message transmission between content computers and electronic devices, then message security is improved, but intermediation servers cannot decrypt payloads and cannot effectively filter unwanted messages
Solution Approach 1:
The system performs preliminary actions by establishing delivery policies and white lists before message transmission occurs. The intermediation server receives and stores delivery policies that specify which content computers are authorized to send messages to which electronic devices. This preliminary configuration enables the server to filter messages based on policy compliance rather than requiring decryption, thus maintaining both security and filtering capability
Solution Approach 2:
The message structure is segmented into distinct components: the payload remains encrypted and intact, while separate metadata fields (origination identifier, destination identifier, policy identifier) are extracted and processed independently. This segmentation allows the intermediation server to validate message routing and policy compliance without compromising the encrypted payload, resolving the contradiction between security and filterability
2Productivity
If intermediation servers forward all encrypted messages without filtering, then message delivery completeness is improved, but bandwidth and resources are wasted on unwanted messages
Solution Approach 1:
Delivery policies are pre-configured and stored in the intermediation server before message transmission occurs. The server uses these pre-established policies to perform rapid policy compliance checks on incoming messages, filtering out non-compliant messages before they consume bandwidth for transmission. This preliminary filtering action prevents resource wastage while ensuring all compliant messages are delivered
Solution Approach 2:
The intermediation server acts as an intelligent intermediary that uses policy identifiers and delivery policies as mediation mechanisms. Instead of forwarding all messages or requiring decryption, the server mediates message flow by matching message metadata against stored policies, allowing only authorized messages to proceed. This intermediary function eliminates unwanted message transmission while preserving delivery completeness for authorized messages
3Object-affected harmful factors
If delivery policies are implemented to filter messages at intermediation servers, then unwanted message filtering is improved, but system complexity increases due to policy management
Solution Approach 1:
The system extracts and processes only essential metadata fields (origination identifier, destination identifier, policy identifier) from messages, separating these from the encrypted payload. This extraction approach simplifies policy management by focusing only on routing-related information, reducing the complexity of policy validation while maintaining effective filtering capability
Solution Approach 2:
The system changes parameters by using policy identifiers as a simplified reference mechanism rather than storing complex policy rules directly. The policy identifier serves as a compact parameter that references pre-stored delivery policies, reducing memory requirements and simplifying the policy management process while maintaining comprehensive filtering functionality
