As the demand for high-speed data transfer and reliable connectivity continues to grow, businesses are upgrading their networks to support 10G infrastructure. A 10G Fast Ring Network ensures not only blazing-fast connectivity but also offers redundancy for mission-critical systems, minimizing downtime during failures. This blog will take you through the entire process of creating a 10G Fast Ring Network.
What is a Fast Ring Network (ERPS)?
A Fast Ring network refers to a ring topology that leverages Ethernet Ring Protection Switching (ERPS) to ensure that data can be transmitted reliably, even in the event of a network link failure. In this setup, multiple network devices such as switches or servers are connected in a circular manner (e.g. switch A → switch B → switch C → switch D → switch A), allowing data to travel in either direction, which ensures network redundancy in mission-critical applications, such as data centers.
ERPS offers sub-50ms failover times, ensuring minimal disruption in case of a link or node failure. If one link in the ring fails, due to cable cuts or hardware failure, the network automatically redirects traffic to the opposite direction. ERPS is particularly useful for metro Ethernet networks, industrial automation, and other mission-critical applications where downtime needs to be minimized.
Why You Need 10G in a Ring Network?
A 10G network can handle massive volumes of data with low latency, which is critical for applications like video surveillance, IoT devices, industrial systems, and data centers. Here’s why you need 10G in a Fast Ring Network:
- Bandwidth: 10G speeds allow for the transmission of large files, high-definition videos, and continuous data streams without congestion. This is essential when you are dealing with data-heavy applications.
- Low Latency: Time-sensitive applications, such as real-time monitoring or financial trading systems, demand minimal latency. 10G networks help reduce the delay in data transmission, improving overall system performance.
- High Scalability: As businesses grow, so does the need for higher capacity. A 10G network ensures that your infrastructure can scale with your needs.
- Redundancy and Reliability: In a ring topology, the use of ERPS ensures that even in the event of a single link failure, the network remains operational. In a traditional Ethernet network, rerouting traffic after a failure can create congestion, slowing down the entire network. With 10G speeds, the high bandwidth allows for smooth failover, maintaining high performance even during link failures.
How to Create a 10G Fast Ring Network?
With ERPS, the failover times in a ring network are typically under 50 milliseconds. A 10G network allows this failover to occur smoothly, as it can handle large amount of data to be rerouted without dropping packets or creating potential bottlenecks, which is critical in time-sensitive applications such healthcare and ITS systems where network downtime can be costly.
Before diving into the installation process, let’s break down the essential components needed to create a 10G Fast Ring network:
1.8-Port Outdoor PoE++ Switch with 4 SFP+ Uplinks
The backbone of your network will be a series of 10G switches (Layer 2 or 3) with built-in redundancy features. This rugged, outdoor-rated switch is equipped with four 10G SFP+ uplinks, which provides high-speed data transfers across the ring network. To enable ERPS, all you need is to toggle the dip switch and a logical ring is formed.
Compliant with IEEE802.3bt standards, this outdoor PoE++ switch can provide up to 60 watts per port, allowing you to power IP cameras, access points, or IoT devices directly through the Ethernet cable. With L2+ management, it also provides advanced functions such as QoS, VLANs, and LACP for enhanced control over your network.
2.10G BiDi SFP+ Modules
The 10G BiDi SFP+ modules are the key to maintaining 10G connectivity between switches. By using two wavelengths for bi-directional data transmission, these SFP+ modules can transmit and receive optical signals over a single fiber strand, cutting fiber costs in half. They are capable of supporting high-speed data transfer rates up to 10Gbps over a distance of 20km, depending on the fiber type.
3.Fiber Optic Cable
Fiber optic cables are an essential tool for connecting the ERPS switches in a ring network. Using light to transmit data, they can easily handle 10Gbps speeds or higher. The high-speed data paths created by fiber allow for seamless rerouting in network disruptions. Unlike copper cables, fiber optic cables maintain signal integrity over extended distances (up to 20km or more). This is crucial in ring networks spread across large campuses, cities, or industrial complexes.
There are two common types of fiber optic cables:
- Pre-terminated Fiber Optic Cable
Pre-terminated fiber optic cables are 100% factory-terminated and under strict quality control and testing in the lab, which ensures low insertion loss and high precision. Since no splicing, polishing, or connector assembly is required on-site, you can save on labor costs and reduce human errors. With connectors already installed at each end, these cables feature a simple plug-and-play setup, ideal for users of any level.
- Direct-Burial Fiber Optic Cable
Direct-burial fiber optic cables are designed for outdoor installations where the cables will be buried directly underground without additional protective conduits. Designed with a tough outer cable jacket and steel strength members, these cables are protected from moisture, solid acidity, extreme temperatures, crushing, and rodents, preventing cable deterioration over time.
Step-by-Step Installation Guide
Now, follow the instructions below to set up a 10G ring network:
Step 1: Plan Your Network Layout
First, it’s cruicail to make sure the distance between each switch is within the limits of the 10G BiDi SFP+ modules, which typcially ranges from 10km to 20km. Then plan the fiber optic cable routing to bypass any obstacles and ensure a clean setip. Moreover, you should ensure that all the switcheshave access to power, either through local power supplies (AC/DC) or off-grid power options such as solar engery.
Step 2: Mount the ERPS Switches
Install the 8-port outdoor PoE++ switches securely on poles or walls. Ensure that the switches are installed at an appropriate height that avoids water damage and protects againast tempering. Then, plug each PoE swicth into a power source.
Step 3: Insert 10G BiDi SFP Modules
After the switches are mounted, the next step is to connect the SFP+ modules to the SFP+ uplink ports. You need to insert 2x SFP+ modules into each switch to create a ring topology. Make sure the modules are properly aligned and gently insert them into the SFP+ ports. You can hear a sound when they should click into place.
Step 4: Connect Fiber Optic Cables Between Switches
Now that the SFP+ modules are in place, it’s time to connect the switches using fiber optic cables. Since you are using 10G BiDi modules, you will only need one strand of single-mode fiber between each switch pair. Plug one end of the fiber cable into the BiDi SFP+ module on the first switch and the other end into the corresponding module on the next switch. Repeat the process between all switches to form a closed loop.
Step 5: Enable ERPS
Most industrial or outdoor switches have a dedicated ERPS toggle switch. All you need is to locate the ERPS DIP switch on each of the 4 switches, and toggle the switch to enable ERPS mode on all switches. This will activate the ring protection protocol, ensuring redundancy is in place. Once ERPS is enabled, the switches will automatically elect one switch as the Ring Master, which will manage failover and rerouting when needed. You can also configure ERPS via the web GUI or CLI of the switch.
Step 6: Conduct a Failover Test
Disconnect one of the fiber optic cables to simulate a link failure betwen switches. If the network doesn’t go offline, it means ERPS has successfully rerouted the traffic to the opposite direction. Then, you need to check the latency and packet loss of the failover. Typically, the recovery time should be under 50 milliseconds or less.
