7. 需求规范¶
原文标题：Requirements Specification
This chapter describes all requirements driving the work to define the Bus Mirroring module.
8. 功能概述¶
原文标题：Functional Overview
Many communication buses in a vehicle are not directly accessible by a tester. The aim of the Bus Mirroring is to enable a tester to listen to the traffic on such internal communication buses.
To avoid flooding intermediate communication buses by traffic that needs to be re-routed over an internal bus, a filtering shall be configurable on each node involved in such a mirroring.
Testers connected via CAN (FD) shall receive unmodified CAN (FD) frames and LIN frames with special CAN IDs.
On intermediate CAN (FD) buses, the mirrored CAN (FD) and LIN frames shall be transmitted in the same way, possibly with re-mapped CAN IDs.
Testers connected via CAN XL or Ethernet shall receive a stream containing current time, identification, and content of CAN (FD), LIN, and FlexRay frames. Ethernet frames shall be mirrored using the Port Mirroring feature of Ethernet switches.
On intermediate CAN XL, FlexRay, Ethernet, and proprietary buses, the same stream encoding as on external Ethernet connections is used.

9. 功能性需求¶
原文标题：Functional Requirements
10. 配置¶
原文标题：Configuration
The source and destination buses shall be configurable ⌈ | Description: | The Bus Mirroring module shall support configuration of the source buses and the destination buses used for mirroring. A bus shall not be configurable both as source and destination bus. | |---|---| | Rationale: | Configuration of the buses participating in the mirroring. |
Applies To: | Dependencies: | - | |---|---| | Use Case: | Mirroring of CAN (FD)/LIN frames to CAN (FD), and of CAN (FD)/LIN/FlexRay frames to CAN XL/FlexRay/Ethernet/CDD. | | Supporting Material: | Concept 634 "Bus Mirroring" |
⌋
Frame filters shall be configurable ⌈ | Description: | The Bus Mirroring module shall support configuration of a set of static frame filters and a number of dynamically assignable frame filters. These filters shall be configurable separately for each source bus. The filters shall be inclusive - if no filter is active, no frames will be mirrored. | |---|---| | Rationale: | Reduce bus traffic on destination bus. |
Applies To: | Dependencies: | - | |---|---| | Use Case: | Adaptation to actual use case. | | Supporting Material: | Concept 634 "Bus Mirroring" |
⌋

11. 初始化¶
原文标题：Initialization
The Bus Mirroring module shall provide an interface for module initialization ⌈ | Description: | The Bus Mirroring module shall provide an interface for initialization of all states and all global variables of the module. Before initialization, the Bus Mirroring module is inactive. | |---|---| | Rationale: | Basic functionality. |
Applies To: | Dependencies: | - | |---|---| | Use Case: | ECU initialization. | | Supporting Material: | Concept 634 "Bus Mirroring" |
⌋
12. Normal Operation¶
The Bus Mirroring module shall collect incoming frames ⌈ | Description: | The Bus Mirroring module shall provide interfaces for the collection of incoming CAN (FD), LIN, and FlexRay frames. | |---|---| | Rationale: | Access to frames from different bus types. |
Applies To: | Dependencies: | Configuration of source buses, see . | |---|---| | Use Case: | Collect input frames. | | Supporting Material: | Concept 634 "Bus Mirroring" |
⌋
The Bus Mirroring module shall filter incoming frames ⌈ | Description: | The Bus Mirroring module shall select incoming frames based on filters. If no filter is active, no source frames shall be mirrored. If filters are active, source frames that match at least one filter shall be mirrored. | |---|---| | Rationale: | Reduce bus traffic on destination bus. |
Applies To: | Dependencies: | Configuration of filters, see , and modification of filters, see . | |---|---| | Use Case: | Monitor timeout of the response to a transmitted request message. | | Supporting Material: | Concept 634 "Bus Mirroring" |
⌋
The Bus Mirroring module shall serialize incoming frames and bus states ⌈ | Description: | The Bus Mirroring module shall serialize incoming frames using a defined mirroring protocol. | |---|---|
