Transceiver Data Filtering for MACsec Header Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transceivers face challenges in implementing protocol functions, such as security protocols, due to limitations in functionality and control signals, particularly in high data rate environments where insufficient time is available to add protocol information to data transmission units.
Innovation Solution
An apparatus with a filter and protocol module that identifies and removes specific data transmission units to create space for adding protocol information, such as MACsec headers, by filtering out predetermined types of data units, allowing for the inclusion of security protocol information without increasing data transmission unit size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protocol information is added to data transmission units in high data rate environments, then security functionality is improved, but insufficient time is available to add protocol information
Solution Approach 1:
The patent applies preliminary action by pre-allocating time resources for protocol information addition. The transceiver is configured with predetermined time resources that are reserved in advance for adding protocol information to data transmission units, ensuring that security processing can be performed without causing time deficits in high data rate environments.
2Adaptability or versatility
If existing transceivers implement protocol functions, then security protocols can be provided, but functionality and control signals are limited
Solution Approach 1:
The patent applies segmentation by separating the transceiver functionality into distinct components: the transceiver itself and the protocol information addition module. This segmentation allows the transceiver to maintain its core functions while the separate module handles protocol information addition, thereby increasing adaptability without excessively complicating the transceiver's internal structure.
Data Source
AI summary
An apparatus comprising: an input for receiving a stream of data transmission units; a filter configured to identify data transmission units of a first predetermined type based on predefined identifying information and generate a second stream of data transmission units comprising said first stream with at least one data transmission unit filtered out; a protocol module configured to identify, based on second predefined identifying information, and in said second stream at least one data transmission unit of a second predetermined type and add protocol information thereto; and wherein the filter being configured to filter out said at least one data transmission unit provides time in said second stream for the addition of the protocol information; and wherein the apparatus includes a transceiver configured to output signals representative of said data transmission units of the second stream with said protocol information added to a transmission medium.
