The Role of SD-WAN in Helping Companies Build IoT Infrastructure

In recent years, the Internet of Things (IoT) has become a hot topic and continues to drive digital transformation for various business sectors. The IoT device itself will run optimally on the 5G network. However, considering the number of IoT devices that a company will deploy, good integration is needed so that its functions run smoothly, including from the network side. To address the growing needs in terms of IoT network traffic which will become increasingly dense, companies need to increase network coverage such as using software or SD-WAN as a pragmatic approach.

How does SD-WAN play a role in IoT Infrastructure Development?

SD-WAN solutions are an evolution of a wide-ranging network. SD-WAN supports applications hosted in multiple locations over all network types and service provider connection types. Here are 3 benefits of SD-WAN in building IoT infrastructure:

1. Security

Data security issues are of course a major concern in business due to the proliferation of cyberattacks. The study by research firm Ovum emphasizes the importance for companies to upgrade their security infrastructure to meet IoT demands, which involves securing end-to-end traffic so that data is protected from cyber threats.

The 5G network will allow applications to operate virtually, and SD-WAN plays a role in preventing unauthorized access to sensitive information in two ways, namely path isolation and security controls. Lane isolation will allow companies to regulate traffic. In terms of security, SD-WAN allows companies to control or prevent traffic based on certain criteria.

2. Simply Designed Management

Cisco Router and Switch Connectivity: Selecting the Right Network Equipment

Many options are available when considering the purchase of a Cisco network device. Which device suits specific system resource and performance needs? It is imperative to perform the required research to learn about what each device has to offer when in need of dependable Cisco router and switch connectivity. One recommendation is to stay within a realm of familiar router and switch models. When a specific component is reliable and offers all that is needed, it does not make sense to choose a different product which could be difficult to configure, learn, and maintain.

Business network professionals may also already know good products that have provided reliable connectivity in many locations. Sometimes the component being selected is for an entirely new purpose or the network itself. In these scenarios, the most familiar component may not cut it. Use these criteria during the evaluation of new devices.

Start by comparing the number of packets that will be forwarded per second. This estimate is only available when conditions are optional. Each additional feature will reduce the number of forwarded packets. Having the ability to upgrade device functionality at a minimal cost is equally important. There is a default number of interfaces or switch ports per component.

Make certain the selected switch or router has multiple interfaces as well as configurations for expansion. If the device needs to support a specific type of interface, make certain the capability is present. Other criteria to consider are the ability to support integrated services, easy manageability, … Read the rest >>>>

IPv6: A Better Way to Move Data Around

IPv6 introduced great enhancements to IPv4. The improvements include Mobility, security, smaller header, address formatting.

Mobility is a new, IPv6 feature. Mobility allows users with mobile network devices to change locations around the network. Mobile IP is an IETF standard that is available for IPv4 as well as IPv6. This standard permits mobile devices to move without disruptions in established networks.

IPSec is another IETF standard for IP network security. It is offered by both protocols. The IP net security characteristics are similar in both environments. IPSec is improved in IPv6 and can be enabled on every node that uses this protocol.

Smaller Header

The header used for IPv6 improves routing efficiency by decreasing the number of records in the routing tables. No broadcasts are produced by IPv6. IPv4 creates broadcasts that generate a high level of network traffic. This network traffic produces an event known as a broadcast storm and the whole network stops functioning. IPv6 replaced broadcast traffic with multicast and anycast traffic.

Address Formatting

The hexadecimal digits A, B, C, D, E, and F represented in IPv6 addresses are not case-sensitive. The IPv6 address string format is not fixed. The next rules are used for IPv6 address string notations: The first 0s in a field are optional. For example 09C0 equals 9C0 and 0000 equals 0. One or more sets of 0s can be deleted and replaced with “::”. Also, only one “::” is permitted in an address.

The “::” symbolization greatly shrinks the size of most … Read the rest >>>>
