Due to the rapid increase in Internet traffic caused by the Corona
disaster, the need to handle traffic efficiently is becoming
increasingly important. In addition, there is a need to increase the
number of traffic exchange points (IXs) in order to make the Internet
more resilient and distributed.
It is said that IXs are concentrated in Tokyo, but they are gradually
being distributed to Osaka, and the amount of traffic exchanged is
gradually approaching that of the ratio of users in East and West
Japan. Expectations for regional IXs are also increasing due to the
demand for local traffic exchange.
In the past, regional IXs were established not only for local traffic
exchange, but also for the purpose of joint transit procurement.
However, new factors such as the deployment of edge caching in CDNs,
the proposed use of folded communications, and the emergence of
latency- and jitter-sensitive applications have led to the development
of regional IXs. However, with the addition of new factors such as the
deployment of edge caches in CDNs, NTT-NGN loopback function, and the
emergence of applications that are sensitive to latency and jitter,
the timing has become right for a renewed discussion on the nature of
distribution, including regional IX.
In this presentation, based on the experiences and knowledge of the
three presenters who have built the Regional IX, we will share the
issues necessary for the sustainable operation of the Regional IX, and
discuss the issues that need to be addressed. We would like to provide
an opportunity to deepen the discussion on the ideal structure of the
Internet in Japan, including Regional IX.
