Huawei OSN 9800 24 Port 10GE Packet Service Processing Board TNV2E224 Overview

TNV2E224: 24*GE/10GE Packet Service Processing Board

As a packet service board, the V2E224 board receives and transmits FE/GE/10GE services, processes packet services, and transmits packets to the cross-connect board for centralized cross-connections.

The V2E224 board consists of the client-side optical module, packet processor, traffic manager, fabric interface circuit, control and communication module, and power supply module

The TNV2E224 boards can be used with the TNU4CTU board.

TNV2E224 supports a maximum of 24 x GE/FE/10GE LAN 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 V2E224 board, the transmit and the receive directions are defined. The transmit direction is defined as the direction from the client side of the V2E224 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.
