Introduction

In D-Link M2M router applications, optimizing the priority of network services plays a crucial role. These routers are often deployed in environments such as remote monitoring, smart cities, and industrial automation, where the timely delivery of critical data—such as sensor readings or real-time control signals—is vital for system stability. By implementing intelligent traffic management and service prioritization techniques like Quality of Service (QoS), M2M routers can ensure that mission-critical packets are processed first, thereby reducing latency and packet loss while enhancing overall network responsiveness.

Furthermore, prioritizing network services improves resource allocation and utilization across the system. In scenarios involving multiple tasks and simultaneous protocols, D-Link M2M routers can classify and prioritize traffic based on application-specific requirements such as bandwidth demand, latency sensitivity, or reliability. This dynamic allocation strengthens data transmission stability and equips the network to respond more flexibly to sudden surges in traffic or unexpected conditions, providing a resilient network foundation for diverse D-Link M2M use cases.

Please note that this example is based on specific prerequisites and topology. D-Link does not guarantee compatibility with all platforms or clients.

Prerequisites

1. D-Link M2M router with QoS Rule Configuration: This feature is applicable to DWM-550-G, DTM-550-G, and DOM-550-G.
2. End Devices:
At least one PC is connected to D-Link M2M router.

 

Network Topology

This topology diagram illustrates a QoS application that makes sure PC A and PC B have dedicated Internet bandwidth. For example, PC A's download speed is limited to 100 Mbps.

QoS Configuration

Before QoS configuration, please check WAN interface status and make sure your M2M router/gateway WAN interface already obtained an Internet.
Go to Status > Basic Network > WAN & Uplink tab

 

1. Enable QoS: Go to the Basic Network > Configuration tab

   Enable Flexible Bandwidth Management

2. Click Add in QoS Rule list and set up PC’s MAC address and select Bandwidth in Resource. Then set up 50 to 60 in the control function. Click Save button
