The availability of SD-WAN solutions is a boon for organizations who do not have the luxury of time to make such costly investments. SD-WAN solutions are quickly gaining popularity in the world of networking. Their rapid adoption has caught the attention of network managers and IT consultants alike.
SD-WAN, also known as Software Defined WAN, is an option that brings together the advantages of the cloud with those of the physical world. It consists of two parts: an IOS or IP, and an OS. A virtual router runs on the IOS, connecting the clients to the Internet.
In the physical world, the physical network components are interconnected via the high-speed cables that serve to connect the routers to each other. Here, the routers themselves are connected to each other by an Ethernet cable. In the cloud, the routers are isolated by means of a VPN (virtual private network) connection. The connectivity between the routers in the cloud can be made via dedicated high-speed connections or through the Ethernet or Wi-Fi connections that are common to a given organization.
In addition to routing and forwarding, the networks at the virtual office need to use the network protocols for data exchange and communication. Among the most popular ones include FTP, POP, SMTP, HTTP, IMAP, and LDAP. The biggest benefit of SD-WAN is that it allows organizations to offer users the same services that their customers can access. Thus, companies that offer dial-up services can easily reach those who have opted for the cloud solutions.
Although the availability of SD-WAN network solutions has been an encouraging factor for network designers, the initial investment is quite high. Moreover, the costs are likely to be higher for smaller organizations that cannot afford to make such investments in the first place. The cost of implementing SD-WAN solutions is also considerably higher than that of the traditional LAN, IP and WAN solutions, so this makes them unattractive for some of the organizations.
A number of factors make SD-WAN network solutions attractive to smaller organizations. First of all, they use a significant amount of the budget that would be allotted for the traditional network solutions. Additionally, they are very easy to manage. They require less infrastructure to operate than traditional solutions, so they are the ideal solution for the small, agile businesses.
Companies that want to adopt SD-WAN solutions should be able to follow clear guidelines to make the right decision. The first thing that one needs to do is to identify which networks they want to connect to. Most of the smaller organizations prefer to connect to the existing LAN and IP networks, while others go for the newer and faster VPN.
The size of the network is another important factor that needs to be taken into consideration. Although SD-WAN can connect to a larger number of networks, it does not mean that it can handle the traffic of several millions of computers. Also, it is necessary to consider how much bandwidth would be required for the entire network. Some networks may not have enough bandwidth, whereas some may be overloaded.
Network solutions for SD-WAN use a specialized virtual server that has the necessary capacity for routing and forwarding the traffic between the computers. In addition, the software used in the routing process is also specialised and designed for the purpose. This software, which is referred to as WANSS, has all the features that can be expected from such a system. The software includes automatic routing of the packet between the internal network and the public network.
With a secure VPN connection, the data from the clients is sent over a secure connection and encrypted as well. The user’s computer receives the data encrypted and decrypted, and is then delivered back to the client in an encrypted form. Thus, there is no risk of the data being intercepted by hackers, making the SD-WAN solution highly desirable for organizations that are concerned about data security.
As compared to the traditional LAN and IP network solutions, SD-WAN has a number of benefits that make it more convenient for small business’s connectivity. However, the costs involved in its implementation make it appealing for many small businesses who do not have the luxury of spending a huge amount of money.
What Is SD-WAN?
A lot of people who have some basic knowledge about networking protocols and the Internet are familiar with the term “SD-WAN” acronym. The truth is, it is more than a basic Internet connection. It has a unique outlook that most networking products do not include. Read on to learn more about this emerging concept.
This system uses the same technologies as Wi-Fi. It uses the Ethernet network to connect computers and computers. The network can also be split into two parts, meaning that a client can connect to the server and from there establish a connection to any other computers.
The client connects to the server through the IP address that the server provides to the client. When there is no Internet connection, the IP address is transmitted by a series of frames or by radio signals. There are different types of transmission methods used such as IEEE 802.11a frames, or IEEE 802.11b frames and a series of frames known as the Smooth Streaming frames.
Networks can be used for VoIP or video streaming applications. Most communication is accomplished using Secure Sockets Layer (SSL) encryption. Secure Sockets Layer is used to encrypt packets between the client and the server. SSL can be viewed as a shared public key infrastructure for the Internet.
There are various servers for SD-WAN including providers and routers. The provider will lease a router and install a layer 2 network connection between the router and its customer. Since all packets sent and received are encrypted, the customer does not have to worry about possible eavesdropping or security breaches.
It is much more cost effective than a typical LAN or WAN network. The WAN is just as expensive, but it takes up much more space in a building. The network can be as small as a single room or office or it can stretch across the entire country.
Traditional network connections are slower than those offered by SD-WAN. Many users complain that they do not receive quality service on a typical WAN connection. There are also computer security issues that can cause major disruptions in the network.
The use of VPNs will greatly improve the speed of the network connection. This way, any data sent or received is encrypted. These can be accessed in many different ways: by using a VPN service or the browser of the client or by directly accessing the data through the server.
Data can be transferred using high-speed connections through the 802.11a and 802.11b standards. These standards offer secure channels, reducing the risk of a security breach. Since all network traffic is encrypted, there is no chance of identifying users and there is no possibility of malicious software.
So, what is SD-WAN? It’s very simple, and a computer is just one of the components. The WAN can connect computers that may not necessarily be equipped with an Ethernet port. This can be a small computer that runs on battery power, a mobile phone, a tablet or even a PDA.
Wi-Fi users who are accustomed to using traditional Ethernet cables to connect to their Wi-Fi enabled devices can transfer data without needing to upgrade their equipment. The network connection does not take up space in the device, so it has a smaller physical footprint. There is a reduced risk of hardware damage as well. SD-WAN users can enjoy the benefits of the WAN, even if they do not have Wi-Fi equipment.
Another reason why this system works so well is because of the amount of bandwidth that can be used. With an allocation of 100 megabits per second, connections can be faster and data can be sent without experiencing delays. So when deciding whether or not to switch to a network for your business, SD-WAN may be the way to go.
