SYSLOG Message Parsing with Length Prefixes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing SYSLOG message transfer protocols face issues with message loss, security vulnerabilities such as information falsification, leakage, and identity spoofing, and inefficient parsing due to the use of unreliable protocols like UDP and the complexity of parsing messages with secure protocols like TCP, which results in high processing consumption and potential errors.
Innovation Solution
Attaching message length information to each SYSLOG message allows for rapid identification and parsing of messages within a transport payload, improving reliability and security by enabling efficient message boundary detection and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If UDP is used to transfer SYSLOG messages, then the transfer protocol is simple and flexible, but message loss occurs and reliability deteriorates
Solution Approach 1:
The patent segments the SYSLOG message transfer process into distinct phases: connection establishment, message transmission with length prefixes, and connection termination. Each phase is handled with specific TCP operations, allowing reliable transfer while maintaining structured complexity only where necessary for reliability.
Solution Approach 2:
The patent applies preliminary action by attaching the message length prefix before each SYSLOG message is transmitted. This pre-processing step enables the receiver to immediately know the message boundaries and length without requiring additional acknowledgment or parsing overhead, thus ensuring reliable transfer without increasing protocol complexity during message processing.
2Reliability
If TCP is used to transfer SYSLOG messages, then transfer reliability improves, but message parsing complexity and processing consumption increase
Solution Approach 1:
The patent applies preliminary action by attaching the message length prefix before each SYSLOG message is transmitted. This pre-processing step enables the receiver to immediately know the message boundaries and length without requiring additional acknowledgment or parsing overhead, thus ensuring reliable transfer without increasing protocol complexity during message processing.
Solution Approach 2:
The message length prefix acts as an intermediary element between the TCP transport layer and the SYSLOG application layer. It provides a clear delimiter that simplifies the interface between reliable TCP delivery and simple text-based SYSLOG processing, reducing parsing complexity while maintaining reliability.
3Reliability
If secure protocols like TLS or SSH are used to transfer SYSLOG messages, then security improves, but message parsing complexity and processing consumption increase
Solution Approach 1:
The patent segments the secure message transfer into two independent layers: the secure transport layer (TLS/SSH) handling encryption and authentication, and the SYSLOG layer handling message formatting and content. The length prefix is inserted at the SYSLOG layer, allowing simple parsing of the application layer while relying on the transport layer for security.
Solution Approach 2:
The message length prefix acts as an intermediary element between the TCP transport layer and the SYSLOG application layer. It provides a clear delimiter that simplifies the interface between reliable TCP delivery and simple text-based SYSLOG processing, reducing parsing complexity while maintaining reliability.
4Productivity
If multiple SYSLOG messages are arranged in one TCP message, then transfer efficiency improves, but message boundary identification complexity increases
Solution Approach 1:
The patent applies preliminary action by attaching the message length prefix before each SYSLOG message is transmitted. This pre-processing step enables the receiver to immediately know the message boundaries and length without requiring additional acknowledgment or parsing overhead, thus ensuring reliable transfer without increasing protocol complexity during message processing.
Solution Approach 2:
The message length prefix acts as an intermediary element between the TCP transport layer and the SYSLOG application layer. It provides a clear delimiter that simplifies the interface between reliable TCP delivery and simple text-based SYSLOG processing, reducing parsing complexity while maintaining reliability.
