What is SDN? SDN stands for Software Defined Network which is a physical separator in the network field originating from the forwarding field. So with SDN you can control many devices at once usually on network equipment such as access points, routers, switches, and so on, so what is SDN and what are the advantages of UniFi UAP-AC-HD products? Let’s look at the following explanation.

Get to know Software Defined Networking (SDN)
Software Defined Networking or SDN is a new network architecture that is more dynamic, adaptive, and cost-effective compared to traditional networks.
For networks with SDN architecture so that it can be flexible and easy to manage the network and control the network if changes occur which will later adapt to business needs.
As for the Software Defined Network, network staff or Network engineers can have power over the management of traffic passing from a central console, so there is no need to configure each other network device such as a switch or access point in a topology.
There are several differences in images between topologies that have not implemented SDN and topologies that have implemented SDN, including:
- Topologies that have not implemented SDN
- Topology that has implemented SDN
Software Defined Networking
Previously, we discussed a little about what Software Defined Networking is and what is the difference between a network that does not yet use SDN and a network that already uses SDN.
Usually Software Defined Networking is applied to modern cloud computing networks instead of using traditional networks. Software Defined Networking is made to replace static network systems in traditional networks. SDN can also concentrate network intelligence on a single network component by separating forwarded data packets from a routing process on network devices. Then in the control field it consists of one or more controller devices which are considered as the brains of Software Defined Networking which is the overall network intelligence that becomes one. However, this concentration has weaknesses in terms of security which if it has been hacked then all topologies can have an impact.
Software Defined Networking Concept
The concept of Software Defined Networking is through physical separation between the forward plane and the control plane. This control plane is located centrally which requires a network operating system that can map logically or logical maps on the entire network topology which will be presented in the form of an API or Application Programming Interface.
Software Defined Networking Architecture
- Live programming
Network management can be set up and programmed directly which is separated from the forwarding function.
- Fast in terms of management
Network management that allows network staff to dynamically adjust traffic from all networks when changes occur.
- Central Management
Having a dynamic nature does not mean not having logical network intelligence. This logical network intelligence is centered on Software Defined Networking controllers which are based on specific software that can maintain a global network, where applications and machine policies act as a single logical switch.
- Configure pragmatically
Software Defined Networking enables network management of configurable, manageable, secure, and optimized resources rapidly through dynamic, automated Software Defined Networking. Which network staff can write their own programming that is not directly dependent on the software used.
- Open standards and vendor neutral
Since Software Defined Networking has an open standards implementation, Software Defined Networking is able to simplify network design and operation according to instructions from SDN network administrators of certain vendor-specific devices and protocols.
Software Defined Networking itself consists of three layers, namely:
The first layer is the Network application layer which is usually used in companies is IDS or intrusion detection system, load balancing, and firewall. Traditional networks still use additional tools to add these features, so with SDN you can change this way by using an application that uses a controller to manage the data plane.
The control layer on this SDN is the translation layer as well as the adjustment of requirements between the application layer and the infrastructure layer in accordance with the Software Defined Networking datapath and Software Defined Networking applications.
At this infrastructure layer, the Software Defined Networking datapath or SDN data path is in accordance with the instructions given by the control data plane interface or CDPI.
The network devices that support the Software Defined Networking system include UniFi UAP-AC-HD. UniFi UAP-AC-HD is a WiFi system that has good performance in terms of combining performance between company branches, has unlimited scalability, and has a more centralized management recognition.
UniFi UAP-AC-HD is designed for the industry that has been refined to be easy to implement and use the hardware that has been provided.
This UAP-AC-HD UniFi controller application is very flexible which you can access using any browser and can also use Android or iOS applications. The software is a powerful software engine and is suitable for use with high performance frequency and low latency.
Features Of Unifi UAP-AC-HD
The main features of UniFi UAP-AC-HD include:
Save Money and Save Time
UniFi UAP-AC-HD is equipped with software that can be installed on various computer devices such as PC, MAC, to Linux. In addition, the UniFi UAP-AC-HD can accommodate private clouds or public clouds. In addition, with the UniFi Cloud Key, you can set the configuration with the default device.
UniFi UAP-AC-HD features the latest in 802.11ac Wave 2 MU-MIMO Wi-Fi technology.
Intuitive UniFi Software
As for configuring and managing access points with an easy-to-learn interface.
By having unlimited scalability, UniFi UAP-AC-HD has the ability to create large and small WiFi networks according to your needs. You can use single or expanded networks in the thousands even if you only maintain one centralized management system.
Network staff can take advantage of software running on the NOC or in the cloud that can manage multiple networks at once. You can see an example of its application in the following image.
Unifi General Specifications UAP-AC-HD
The following are the general specifications of the UniFi UAP-AC-HD:
Indoor and Outdoor
This UniFi UAP-AC-HD access point can be used indoors or outdoors. This AP is equipped with WiFi capability with a very wide range so that it can cover the outdoor area better. The biggest challenge of outdoor AP is extreme weather, where this unifi has the ability to withstand both indoor and outdoor.
Simultaneous Dual Band
This Unifi already has simultaneous dual band capability which is designed so that consumers can use the 2.4GHz and 5GHz wireless spectrum for a wider range of users. The 5GHz band is great for streaming media, as it provides more than seven times the number of unstacked connections for a more sneezing, organized network.
Connection Rate 2.4GHz Up to 800 Mbps
With the 2.4GHz wireless spectrum, it has high speeds of up to 800 Mbps. The 2.4 GHz spectrum is still used in various devices with WiFi capabilities such as laptops, tablets, smartphones, printers, and so on.
Radio Connection Rate 5GHz up to 1733 Mbps
Not only 2.4GHz, Unifi has 5GHz which has speeds of up to 1733 Mbps which is quite fast in today’s modern era. But only a few devices that already have 5 Ghz just like a new MAC device or a new Android device.
Accommodate WiFi Users Up To More Than 500 Users
Unlike ordinary access points, UniFi is equipped with a processor and memory with a high capacity. Of course, this will increase the number of users up to 500 users.
That’s our discussion about Unifi UAP-AC-HD and the concept of Software Defined Networking which can use the latest architecture in terms of configuration, data traffic management and so on.
