Huawei OptiX OSN 3500 ATM Features

The OptiX OSN 3500 supports the application of several types of ATM services.

Supported Services and Traffic Types

The OptiX OSN 3500 supports CBR, rt-VBR, nrt-VBR and UBR services, but does not support ABR services.

*  The CBR services apply to voice services, and video services and circuit emulation services of a constant bit rate. These services require guaranteed transmission bandwidth and latency.
*  The rt-VBR services apply to audio and video services of a variable bit rate.
*  The nrt-VBR services are mainly used for data transmission.
*  The UBR services are generally used for LAN emulation and file transfer.
In terms of the supported services and traffic types, the OptiX OSN 3500 meets IETF RFC2514, ATM Forum TM 4.0, and ATM Forum UNI 3.1 Recommendations.

Application of Bandwidth Exclusive ATM Services

When the bandwidth is not shared, ATM services are processed by the ATM service processing board, at the ATM layer of only the source and sink NEs. On intermediate NEs, only SDH timeslot pass-through is performed, without ATM layer processing. In this case, each ATM service exclusively occupies a VC-3 or VC-4 path. At the central node, the ATM services are converged to an STM-1 or STM-4 optical port for output.

As shown in below picture, the 34 Mbit/s ATM services of NE1 and NE3 exclusively occupy a VC-3 bandwidth each. The 155 Mbit/s ATM service of NE2 exclusively occupies a VC-4 bandwidth, and only the SDH timeslot pass-through is performed at NE3. After the three services reach the central station NE4, they are converged by the ATM board and are output through the 622 Mbit/s optical interface on the front panel.

 

Application of Bandwidth Shared ATM Services

The VR-Ring and VC-Ring realize the bandwidth sharing and the statistical multiplexing for ATM services. The ATM services on each NE share the same VC (VC-3, VC-4, or VC-4-xv) path and are processed at the ATM layer of all NEs.

As shown in below picture, NE1 accesses E3 ATM traffic from the tributary board and sends it to the ATM board for ATM switching and protection configuration (1+1 or 1:1). Then, after the traffic is encapsulated into VC-4-xv, it is sent to the line by the cross-connect board. NE2 accesses STM-1 ATM traffic from the optical interface, and then performs the ATM switching and protection configuration. At the same time, the ATM traffic from NE1 is dropped at NE2 for ATM layer processing. Then, the locally accessed traffic and the traffic from the upstream are encapsulated into the same VC-4-xv and sent to the downstream NE. The processing at NE3 and NE4 is similar. One VP-Ring/VC-Ring has a maximum bandwidth of 300 Mbit/s.

Application of IMA Services

The inverse multiplexing for ATM (IMA) technology is used to demultiplex an ATM integrated cell flow into several lower rate links. At the other end, the lower rate links are multiplexed to recover the original integrated cell flow.

The IMA technology is applicable when ATM cells are transmitted through an interface of the E1 rate or other rates. The IMA technology only provides a path, and does not process service types and ATM cells. The signals at the ATM layer and a higher layer are transparently transmitted.

OptiX OSN 3500 Product Networking

The OptiX OSN 3500 intelligent optical transmission system (the OptiX OSN 3500 for short) developed by Huawei is the next-generation intelligent optical transmission equipment.

The OptiX OSN 3500 is of a “universal switch” architecture. That is, the OptiX OSN 3500 can be used in packet mode or in TDM mode. When used with the other equipment of Huawei, the OptiX OSN 3500 supports various networking applications, such as the pure packet mode application, hybrid networking application (overlay networking of the packet mode and TDM mode), and pure TDM mode application. By using a proper networking solution, the data service and conventional SDH service can be processed in the optimal manner.

the OptiX OSN 3500 is mainly used at the convergence layer and backbone layer of the metropolitan area network (MAN). The network application scenarios are described as follows:

*  In TDM networking, can be networked with the other OptiX transmission equipment (the OptiX OSN 9560, OptiX OSN 9500, OptiX OSN 7500 II, OptiX OSN 7500, OptiX OSN 3500 II, OptiX OSN 2500, OptiX OSN 1500, OptiX OSN 500, and OptiX OSN 550) to optimize the carrier’s investment.
*  With the packet switching technology, can constitute a packet data transmission network with the other OptiX transmission equipment (the OptiX OSN 7500 II, OptiX OSN 7500, OptiX OSN 1500, OptiX OSN 500, OptiX OSN 550, OptiX PTN 910, OptiX PTN 950, OptiX PTN 1900, OptiX PTN 3900, and OptiX RTN 900) to meet the requirement for bearing IP services.
*  Can be flexibly networked with WDM equipment and Metro equipment.
*  Can transparently transmit services over third-party Layer 2 networks, allowing end-to-end configuration and management.

Unified switching architecture
OptiX OSN series products use a unified switching architecture, which can meet the requirements of conventional services and mushrooming packet services.

Support for 3G/LTE mobile backhaul
OSN 3500 provides a comprehensive solution for 3G/LTE mobile backhaul based on its packet domain to achieve convergence and scheduling of wireless services at the core layer.

Built-in WDM technology enabling flexible networking
OSN 3500 uses the built-in WDM technology to transmit several wavelengths over an optical fiber. This feature allows OSN 3500 to interconnect with WDM equipment to achieve flexible networking.

TP-assist, care-free maintenance
The TP-assist implements care-free maintenance solutions for packet transport networks (PTNs) based on the MPLS/MPLS-TP architecture. The OSN 3500 provides a planning tool for PTNs, which enables end-to-end visible service configuration of media gateways and instrument-free site deployment. Moreover, the OSN 3500 supports automatic fault locating and performance monitoring of packet services.

Optix OSN3500 optical interface board SSNISL64

OSN 3500 is a new-generation optical transmission system developed by Huawei. It adopts a unified switching architecture and can function as an MPLS/MPLS-TP-based packet device or a TDM device. When working with other devices of Huawei, OSN 3500 supports various networking modes, including the pure packet mode, hybrid networking (packet + TDM) mode, and pure TDM mode, achieving optimal processing for packet services and traditional SDH services. Thus, OSN 3500 efficiently transmits voice and data services over the same platform.
