3D Mesh Backbone Solution

backbone network modernization 960

As information technologies develop, backbone network traffic grows rapidly and some links become severely congested. In most cases, network traffic is not uniformly distributed. Network edges may have light load while core areas become bottlenecks. In addition, DC interconnection services generate a large amount of east-west traffic, straining the traditional backbone network architecture that was designed for north-south traffic. The future-oriented 3D backbone network architecture allows for dynamic sharing of network resources, supporting efficient traffic transmission and improving network availability.

The rapid development of Internet services and other new services, and the comprehensive cloudification of network data storage, drive operators to perform Internet-based transformation and construct a DC-centric next-generation network architecture. 3D backbone network architecture better meets new services' requirements on traffic, latency, network robustness, and flexibility, supporting all-cloud evolution of operator networks.

    Hundreds of Billions of Connections

    4G enables each cell to provide thousands of connections, but even this connectivity cannot support a fully connected world. By 2025, the number of connections per square kilometer will reach one million, requiring immense growth.

Solution Features

10 1

Unlike independent two-plane networks, 3D networks do not require additional interconnection boards

Creating an independent plane to interwork with existing networks requires client-side interconnection and extra regeneration boards, increasing TCO. The construction of 3D backbone networks does not require extra regeneration boards. This reduces costs and E2E latency and shortens time to market (TTM). In addition, 3D backbone networks support unified O&M and share a unified NMS and spare parts.

4 1

Reduced congestion on core links and improved wavelength utilization over the entire network

A minor expansion can double the capacity. The entire network is a 40/80-wavelength system, but wavelength utilization varies. System capacity is limited by several heavy-traffic links. Implementing 3D traffic distribution for several heavy-traffic links reduces network-wide wavelength utilization, doubling the system capacity.

5 2

Enhanced network availability in key areas, meeting requirements of future services

In addition to the original communication networks, more high-availability resources are needed to provide more degrees and higher availability for high-value services such as telemedicine, autonomous driving, and Internet of things (IoT). The construction of 3D backbone networks multiplies reachable route resources in key areas. 3D backbone networks can use ASON and TSDN to greatly improve service survivability.

2 1

Network latency optimized through link expansion, reducing TCO

On a 1000 km WDM transmission network, 98% of link latency is caused by optical fibers and DCMs. Link expansion enables the selection of the shortest path and DCM-free solution, supporting the lowest latency.
