For talkers in an AVB/TSN network, the following requirements from the AVnu Base and Pro AV Functional Interoperability Specification 1.1 are particularly relevant #145
Certainly! For talkers in an AVB/TSN network, the following requirements from the AVnu Base and Pro AV Functional Interoperability Specification 1.1 are particularly relevant:
Time Synchronization
IEEE 802.1AS (gPTP)
Requirement: Talkers must implement the generalized Precision Time Protocol to synchronize their clocks with the network.
Purpose: Ensures accurate timing for media stream transmission, allowing synchronization with listeners and other devices.
Stream Reservation Protocol
IEEE 802.1Qat (MSRP)
Requirement: Participate in the Stream Reservation Protocol to reserve network resources for outgoing streams.
Purpose: Guarantees that sufficient bandwidth and resources are available, ensuring quality of service (QoS) for time-sensitive data.
Traffic Shaping and Queuing
IEEE 802.1Qav (Credit-Based Shaper)
Requirement: Implement traffic shaping mechanisms to control data transmission rates.
Purpose: Manages network congestion and ensures timely delivery by regulating packet flow, reducing latency and jitter.
Layer 2 Transport Protocol
IEEE 1722
Requirement: Support encapsulation of audio/video data into AVTP (Audio Video Transport Protocol) frames for Ethernet transmission.
Purpose: Enables proper formatting of media data for network transmission.
Device Discovery and Control
IEEE 1722.1
Requirement: Implement protocols for device discovery, enumeration, connection management, and control.
Purpose: Allows talkers to advertise capabilities, discover listeners, and establish stream connections.
VLAN Tagging and Prioritization
IEEE 802.1Q
Requirement: Support VLAN tagging and priority code points (PCP) in Ethernet frames.
Purpose: Prioritizes time-sensitive traffic over other types, maintaining performance of audio/video streams.
Compliance with AVB System Profiles
IEEE 802.1BA
Requirement: Adhere to defined AVB profiles specific to talker devices.
Purpose: Ensures interoperability and consistent behavior across different manufacturers' equipment.
Latency and Jitter Requirements
Requirement: Meet specified maximum latency and jitter parameters for stream transmission.
Purpose: Ensures data reaches listeners timely, maintaining audio/video quality.
Media Format Support
Requirement: Ability to encode and transmit supported audio and video formats.
Purpose: Provides compatibility with media types that listeners can receive and process.
Interoperability Testing
Requirement: Undergo testing to verify compatibility with AVB/TSN standards and other devices.
Purpose: Confirms reliable operation within a heterogeneous network environment.
Network Management and Diagnostics
Requirement: Support network management protocols (e.g., SNMP) for configuration, monitoring, and diagnostics.
Purpose: Facilitates device management and troubleshooting within the network.
Security Measures
Requirement: Implement security features to protect against unauthorized access and ensure data integrity.
Purpose: Protects media streams from tampering or interception.
Scalability
Requirement: Efficient operation in networks of varying sizes and complexities.
Purpose: Ensures consistent performance as network demands grow.
Power Management
Requirement: Support efficient power usage, possibly complying with Energy Efficient Ethernet (IEEE 802.3az).
Purpose: Reduces power consumption, beneficial for energy savings and portable devices.
Additional Considerations Specific to Talkers:
Stream Reservation Talker Role:
Must generate and transmit MSRP Talker Advertise messages to initiate stream reservations.
Handle dynamic stream reservations, adapting to network changes or listener configurations.
Traffic Shaping:
Implement the Credit-Based Shaper (CBS) to regulate transmission rates.
Ensures the transmission rate aligns with reserved bandwidth, preventing congestion.
Media Clock Generation:
Provide accurate media clocks for synchronization with listeners.
Use network time from IEEE 802.1AS for timestamping media frames.
Handling Multiple Streams:
Ability to transmit multiple simultaneous streams if required.
Manage resources to maintain performance across all streams.
Quality of Service (QoS) Compliance:
Set appropriate priority levels in VLAN tags to ensure correct handling by network devices.
Payload Format Compliance:
