TNV3E404 Is Huawei OptiX OSN 9800 4 Port 50GE/100GE Packet Service Processing Board
Huawei OptiX OSN 9800 4 Port 50GE/100GE Packet Service Processing Board TNV3E404 Overview
TNV3E404: 4 x 50GE/100GE Packet Service Processing Board
The TNV3E404 board has only one variant: TNV3E404Q01.
As a packet service board, the V3E404 board receives and transmits 100GE/50GE services, processes packet services, and transmits packets to the cross-connect board for centralized cross-connections.
The V3E404 board consists of the client-side optical module, packet processor, traffic manager, fabric interface circuit, control and communication module, and power supply module
The TNV3E404 supports 4 x 100GE/50GE services and implements L2 processing to the services. It supports functions and features such as Layer 2 switching and Multiprotocol Label Switching (MPLS).
In the signal flow of the V3E404 board, the transmit and the receive directions are defined. The transmit direction is defined as the direction from the client side of the V3E404 to the backplane, and the receive direction is defined as the reverse direction.
Transmit direction
The client-side optical module receives optical signals from client equipment, and performs O/E conversion.
After receiving the electrical signals, the packet processor decodes the signals, performs serial/parallel conversion, searches for routes and matches addresses for data services, implements L2 functions such as protection, OAM, and QoS for the data services, and sends the data services to the traffic manager.
The traffic manager performs traffic shaping and queue scheduling for the received service packets and then sends the packets to the fabric interface circuit.
The fabric interface circuit converts the service packets into fabric packets and sends them to the cross-connect board through the backplane.
Receive direction
The fabric interface circuit converts the packets coming from the cross-connect board into service packets and sends the packets to the traffic manager.
The traffic manager performs traffic shaping and queue scheduling for the received service packets and then sends the packets to the packet processor.
The packet processor implements L2 functions such as protection, OAM, and QoS for the data services, performs parallel/serial conversion, and generates electrical signals.
The client-side optical module performs the E/O conversion of electrical signals, and then outputs optical signals to the client equipment.
