Thanks to technology D-Link Green, we will have a energy saving when using this switch since it regulates the intensity of the current depending on the length of the network cable that we have connected. This switch supports flow control and uses the typical store and forward scheme, it also supports up to 4 QoS queues (802.1p) to always provide the highest possible performance and supports traffic of up to 16Gbps.
A very important feature of this switch in its version C6 and higher of the hardware, is the incorporation of IGMP Snooping, necessary to use it without problems when we have IPTV services that use multicast traffic. His little brother the D-Link DGS-105 it also incorporates this feature.
Another strong point of this team is that does not incorporate fan, therefore it is completely silent. In the tests carried out we have verified that the switch does not heat up at all.
In the following video you can see the unboxing of the D-Link DGS-108 and also its main technical characteristics:

We must also remember that the installation of an unmanageable switch is completely Plug & PlayWe will only have to connect our router or access point to this switch with a network cable to give connectivity to the switch to the local network, later it is enough to connect the rest of the equipment via cable.
This eight port unmanaged switch comes in a small white box. In the upper right we find a message that this device is Gigabit and that it is ideal for fast data transfers. At the bottom it indicates that we can connect more computers, consoles and players to our local network, in addition the installation is easy and fast so it is not necessary to carry out any type of installation, finally, we will have the possibility of transferring data to a speed of up to 2,000Mbps per port (1Gbps Full-Duplex).
On the back of the box we find more features of this D-Link DGS-108 non-manageable switch. In the upper left we find a brief guide on how to use this device and the benefits of using it in our network, it also indicates with a diagram how we should connect the devices (the connection between the router and the switch and in turn, to the different wired devices we want to connect). On the right side of the box we find different models of D-Link switches and a brief comparison between all of them.
On the right side of the box we find the fundamental point of this switch: the installation is to connect and function, totally plug & play, without the need for any type of configuration. On the left side of the box we will find the main technical specifications of the switch that we have told you in the introduction of the analysis, the content of the box and also the duration of the warranty.
When we open the box, we find a gray switch with a metal housing perfectly protected by a plastic. The contents of the box for this D-Link DGS-108 unmanaged switch is as follows:
- D-Link DGS-108 switch
- Current transformer
- Quick installation guide and equipment warranty.
A very important detail is that no network cable is incorporated in the box of this switch to start the set-up, we will need to buy the network cables separately. We must say that the power cable is somewhat shorter than we would like, if we are going to place the switch very far from a socket or on top of a piece of furniture with the power strips on the floor, it is very likely that we will have problems . Longer power cords need to be provided by manufacturers to locate the device in the proper place.
On the front of the switch we find a device power LED and eight LEDs that indicate the status of the wired connection. If we have a Gigabit link, the LED color will be green, if we have a 100Mbps or 10Mbps link it will be orange. Of course on this front we also find the 8 Gigabit Ethernet ports for the LAN.
On the sides of the switch we do not find anything remarkable, only ventilation grilles since this switch does not have active cooling but only passive cooling. In the back is where we find a Kensington connector to prevent theft of the switch, a ground connection and finally the power connector, this switch needs a current voltage of 5V, and a current intensity of 1A.
Once we have known the external appearance of this equipment, we will check its performance in our test laboratory.
An unmanaged switch works at layer 2 of the TCP / IP protocol stack, that is, it works at the link layer. Being in the link layer, if we connect this device to a router, and two computers with jPerf client-server to the switch, the traffic will not go through the router (network layer) but directly through the switch (link layer). However, we are going to connect two computers directly to the switch, and the switch without being connected to any router. Since we are in the link layer, we must set private IPs on each of the computers and proceed to performance tests.
Once we have configured the local network and set the IP addresses, we run a Jperf client-server. The results are the following:
With 100 TCP threads we achieve a speed of 96.8MB / s, an excellent performance to transfer multiple files at maximum speed.
With 250 TCP threads we achieve a speed of 96.2MB / s, we continue to have excellent performance.
With 500 TCP threads we achieve a speed of 96.4MB / s.
With 750 TCP threads we achieve a speed of 93.1MB / s.
With 1000 TCP threads we achieve a speed of 82.9MB / s, which ensures the transfer of hundreds of files simultaneously between the computers on the local network.
In the following summary table you can see the values that we have obtained with different number of threads:
|D-Link DGS-108||96.8MB / s||96.2MB / s||96.4MB / s||93.1MB / s||82.9MB / s|
This switch has performed excellently in performance tests, as you have seen, the speed is fantastic regardless of whether we have 100 concurrent TCP threads as if we have 1,000 TCP threads, we can transfer hundreds of files simultaneously through the local network domestic. We remind you that this equipment allows a maximum transfer rate of 16Gbps which ensures that we can transmit and receive at the maximum speed (1Gbps) in each of the ports as long as the auto-negotiation is at 1Gbps Full Duplex.
- Magnificent design, with a very small size and also has a metallic finish that provides greater robustness.
- Ease of installation as it is completely Plug & Play.
- It incorporates IGMP Snooping for IPTV services with multicast traffic.
- Computer power status LED.
- The green (Gigabit) and orange (Fast-Ethernet) status LEDs are very useful to control what is happening in our network and if the wired devices are auto-negotiating correctly.
- The performance achieved by this unmanageable switch has been excellent in all benchmarks.
- Excellent price: This switch can be found in stores for approximately € 30.
- Shorter power cord than desirable.
- Does not include Ethernet network cable.
This unmanageable switch with 8 Gigabit Ethernet ports is ideal to expand the Ethernet ports of our router, its reduced design will make this switch go unnoticed since it fits anywhere. If we decide to display it, its metallic finish will provide maximum robustness. Taking into account the performance of this switch, it is completely valid for small offices, although it is possible that the 8 Gigabit Ethernet ports reach us somewhat fair since we can only connect 7 devices via cable (one port must be connected to the network).
The star function of this switch is IGMP Snooping, ideal so that if we have IPTV services in our home, the network does not collapse. We must remember that this function allows multicast traffic to reach only the decoders that have requested it, and not to all the computers on the local network.
This D-Link DGS-108 switch will be the non-manageable switch that we will recommend from now on, not only for its performance and characteristics but also for its price, and we can find it in stores for only € 30.
Taking into account the technical characteristics, the performance achieved in the tests and its price, RedesZone’s assessment is as follows:
We hope you liked the analysis of the D-Link DGS-108, if you have any questions you can comment. We recommend you visit the page dedicated to the manufacturer D-Link, where you will find more analysis of their devices.
