What is Open Networking? ~Comparing advantages and disadvantages with conventional networks~

Introduction

From this time, we will regularly post articles about Open Networking, which has been spreading in the network industry in recent years. So, in this first article, who is open networking in the first place? I will explain about

There are other articles related to Open Networking, so please see the articles that interest you from the "List of articles" below.

What is open networking? ?

traditional network

First, let's talk about traditional networking, not open networking.

In the conventional network, the network OS (NOS), the switch that is the housing, and the optical module are all provided by one company. The advantage of this is that you don't have to worry about selecting the NOS and optical modules that are compatible with the switch, and you can unify support for each. However, on the other hand, it is necessary to use genuine optical modules (vendor lock-in), which increases the overall cost. Open networking is becoming popular in recent years.

Open networking was born out of a need for more flexibility compared to traditional networks.

As the name suggests, open networking is an open network in which NOS, switches, and optical modules can be freely selected and combined. This makes it possible to flexibly build a network that meets the user's needs. The biggest advantage is cost reduction. The larger the scale of the network, the more optical modules are required, and I believe that this is a factor that cannot be ignored in terms of cost. However, in open networking, total cost reduction can be achieved by choosing 3rd party optical modules that are cheaper than genuine optical modules.

However, along with the advantages, there are also disadvantages. Because it is possible to choose freely, it is troublesome to check combinations/compatibility for each vendor, and support/maintenance contact points are decentralized.

Finally, we will introduce the open networking model that we provide based on this issue.

We can integrate the various products currently handled by Macnica and provide them to customers. This allows us to reduce the customer's work by conducting product combination tests in advance. In addition, we will also consolidate the support/maintenance contact point, so customers will not have to go through the trouble of changing contact points for each product.

We can deliver solutions that solve the problems of open networking to everyone.

We are also working on the following as open networking.

・Automatic network construction of white Box switches using automation tool (Ansible)

・Construction of ZTP (Zero Touch Provisioning) environment

・In-op test between different NOS

・Monitoring/visualization of Box switches using OSS telemetry tools

・In-op test with 3rd party optical module and white Box switch

・Data plane program using P4

etc…

We will cover the above topics in future articles. First, in the next installment, I will introduce how to automate the construction of a white Box switch using an automation tool called Ansible.

Ansible will be a very powerful tool for improving work efficiency using white Box switches, so please take a look if you are interested.

Finally, we would like to introduce a service that will help you open up your network environment.

About Open Networking Remote Verification Service

I have explained open networking in this article, but I think there are some concerns when it comes to actually introducing it.

"NetworkOSis worried about operability"

I want to usewhite Box switches and3rd party optical modules, but I don't have the budget or the time.""

"I'm interested in open networking, but I don't have an environment where I can touch it."

This service was born with the desire to lower the threshold of open networking and provide an environment where many people can actually experience open networking and conduct tests and verifications.

This makes it possible to verify the operability of the network OS and perform tests combining network OSes from various manufacturers, white Box switches, and optical transceivers.

It is a service that allows you to easily verify open networking, and the basic configuration is free of charge.

You can check the downloadable materials for available network OS and white Box switches, specific use cases, and how to apply. The materials can be downloaded from the URL listed in the information email by answering the questionnaire from the "Macnica Network OS Remote Verification Service" below.

These people are using the remote verification service.

Here are some testimonials from people who have actually used the service.
