NTT West provides fixed communication services (such as fixed-line telephone and FTTH) in 30 prefectures in western Japan.
”FLET'S Hikari" is the name of FTTH service that NTT-West provides.
The services NTT-West provide is required to be "stable" and "high quality".
Our business challenge is the cost(CAPEX/OPEX) reduction.
We, The R&D center at NTT-West works to restructure the data center infrastructure of FLET'S services with virtual infrastructure technologies, aiming for cost reduction.
In order to overcome these challenge, we need to be further advanced our server infrastructure.

We have examined the OpenStack(Kiro)-based server infrastructure with general-purpose IA (Intel Architecture) server from six months ago, and are faced with several problems related to Neutron in our examine.
We will introduce these at our session.

First, we introduce the current situation and the next challenges about our server infrastructure, and the functions and performance requirements that require our next-generation server infrastructure in order to overcome the current challenges.

Second, in terms of functionality.
Our Service works on "dual stack" (IPv4/v6) and we need IPv6 implementation.
IPv4 exhaustion is becoming all the more a serious problem, due to the appearance of container technology and the advance of virtualization.
Neutron should be ready for IPv6 to provide functions such LBaaS and FWaaS.
We need UDP implementation on LBaaS.
LBaaS is not able to handle UDP traffic at the present moment.
There are many UDP-based applications (such as SIP and Radius) in our services.

Last, in terms of performance.
The transmission rate of network nodes is not enough for the SLA of IP-Phone (or fixed-line telephone) services.

For this evaluation and report, we've been cooperating with Canonical, VirtualTech Japan and NTT Software Innovation Center.
We show the details of the above, and expect to make progress on these studies through discussion with developers and contributors.
