What is the Concept of Network Bonding?
Network bonding means to bond multiple ethernet ports together, making them appear as a single interface in logical terms. This enables redundancy and load balancing capabilities, increasing the availability and reliability of network connections. When a physical interface of a device fails or becomes unavailable, data flows seamlessly switch to other available physical interfaces, ensuring uninterrupted network connectivity. Additionally, through load balancing algorithms, traffic can be evenly distributed across multiple physical interfaces, improving network performance and throughput.
Network bonding plays a crucial role in building highly available and reliable network environments, especially in critical applications and scenarios that demand high network connectivity.

The Benefits of Network Bonding on VoIP Gateways&SBCs
Active-Standby Redundancy: In the event of a failure or unavailability of the primary node (main network interface), the system can automatically switch to a backup node (secondary network interface), ensuring network connectivity and availability.
Load Balancing: By effectively distributing traffic across multiple physical interfaces, Network Bonding optimizes the bandwidth and processing capacity of network, enhancing network performance and throughput, and ensuring efficient network operation.
Fault recovery and fast switching: In the event of a failure or unavailability of the primary node, the system can automatically switch traffic to the backup node, ensuring fast fault recovery and minimizing downtime and impact on business operations.
In summary, Network Bonding improves network reliability, availability, and performance by implementing redundancy, load balancing, and fast switching. It enables networks to better handle failures and high loads, providing stable and efficient network connectivity.
Applications
Financial Industry: Financial transactions require highly reliable networks, as any communication interruption or data loss can result in financial losses and trust issues. A high-reliability network ensures the security and accuracy of financial transactions.
Telecommunications: Communication services provided by operators need to guarantee high reliability because any communication interruption or quality issues may lead to user dissatisfaction, churn, and reputation damage. A high-reliability network ensures consistent and stable communication services.
Large Enterprises: Large enterprises rely on networks for day-to-day operations and communication. Network failures or interruptions can have a negative impact on productivity and efficiency. A high-reliability network ensures business continuity and stability for enterprises.
In addition, industries such as healthcare, logistics, and public safety also require high-reliability networks to support critical applications and ensure service reliability. A high-reliability network can mitigate potential risks, improve work efficiency, and ensure secure information transmission.
Network Bonding Configurations
Session Border Controller
1.Log in to the system's web interface and enable dual Ethernet port bonding by configuring the desired ports to be bonded. Once enabled, connect both Ethernet ports to the switch using Ethernet cables.
2.When both Ethernet ports are functioning properly, the port with the lower index value serves as the primary port, while the other port monitors the connection status without transmitting network traffic. In the event of a failure on the primary port, network traffic switches to the backup port.
MTG Series Digital VoIP Gateway
1.Log in to the web-based network configuration interface and enable dual Ethernet port bonding. Once enabled, connect both Ethernet ports to the switch using Ethernet cables.
2.When both Ethernet ports are functioning properly, GE0 serves as the primary port, while GE1 remains idle and only monitors the connection status. In the event of a failure on GE0, network traffic switches to GE1.
DAG Series Analog VoIP Gateway
1.Log in to the local network through the web interface and enable dual Ethernet port bonding. Once enabled, connect both Ethernet ports to the switch using Ethernet cables.
2.When both Ethernet ports are functioning properly, GE0 serves as the primary port, while GE1 remains idle and only monitors the connection status. In the event of a failure on GE0, network traffic switches to GE1.
Bonded Ethernet Connection
1.After enabling dual Ethernet port bonding in the web interface, connect both bonded Ethernet ports to the same switch using two Ethernet cables.
2.Check the connection status of the Ethernet ports. If one of the bonded ports fails but the network transmission remains uninterrupted, it indicates that the bonding is functioning properly.
