An exhibition of the Network Technology event "Interop TOKYO 2012" was held at Makuhari Messe in Chiba Prefecture on June 13-16.
Interop TOKYO is also an exhibition, but also a place where companies bring the latest network equipment to test and demonstrate new technologies.ShowNet is the experimental network at the venue, which can be said to be the most advanced domestic.
The theme of this year's shownet is "Reborn to the Future (playback for the future)".After the IPv4 address depletion, which had a sense of crisis until last year, became a reality, this year, it stated on the theme of "What is there?"
Shownet holds the "ShowNet Walking Tour" several times a day, which is an annual project, which is an annual project to tour Shownet facilities.If you participate in this, you can learn about NOC (Network Operations Center, the center of the network) and POD (Pedestal Operation Domain, network relay point) with explanations by NOC members.
Here, I would like to report on this year's showNet, focusing on the showNet walking tour.
Shownet's NOC is largely on the Hall 5's most connected passage side.
This NOC consists of one backbone and two corners seen in the data center.Communications between backbone and data centers and data centers are also experimented.In addition, it is a fun taste every year that a whiteboard is provided next to each of the racks and the message of the NOC members' wishes.
Among the two data centers, Ethernet fabric (multi -pass Ethernet) technology is used.Data Center 1 uses Cisco Fabric Path technology, and data center 2 (right) uses brocade VDX technology.
Both data centers are connected to the L2 OVER L3 tunneling by OTV, as well as a multi-service network network service network by VPLS and Multi Chassis-Lag (MC-LAG) in an L2 redundant configuration.
It should be noted that the NOC server is virtualized most, so that even if the physical server arrives just before, it is only necessary to operate the set -up virtual server in advance.

In the backbone corner, a variety of racks are lined up, from external connections connected to Otemachi to where the connection of each booth pass through the backbone.
The network monitoring racks are also noticeable, and they use a DPI (Deep Packet Inspection), which examines the contents of communication, not only drop the problem packet, but also analyze attacks, visualize traffic, and turn into cash.。This time, one of the themes is also a targeted attack countermeasure, and we are monitoring backbone traffic at the entrance and exit.
The latest alert system "DAEDALUS", which is familiar with the NOC in recent years and visualizes communication such as attacks by the Information and Communication Research Organization (NICT), is also on display.

In the NOC backbone corner, racks for each theme are also lined up.
The 40GIGABIT Ethernet (GBE) device is collected, a 100GBE device, and an interconnection is provided.Mr. Uta, a NOC member, explained, "This year, 40GBE products have increased at a stretch and the price has dropped. Is this going to spread?"
Interop has been handling IPv6 for many years, and this time has also set up an "IPv6 Migration" rack that arranges some IPv6 migration technologies such as NAT64 and SA46T.
OpenFlow is one of the themes, and while the name is ahead, we present a case of use.A system is also experimented with the introduction of OpenFlow in the "Life" rack of the "Life" network of the Shownet staff, and analyzing the flow to the DPI when the incident occurs.
Introduced a new attempt in network monitoring.For EtherOam, L2 Ethernet is constantly monitored and interconnected tests in the real user network.Console management has been served not only for conventional emergency access applications, but also for real -rating from the beginning of construction.The measurements are also intended to be efficiently tested and verified because cache and DPI are multiplexed.

Also devised facilities.In the prominent part, in this year's NOC, LEDs line up at the rack door and glow.There is also an exhibition that can control this from a tablet terminal.This technology can be used in practical use to change the color according to the temperature of the server or to show visits to visits on the floor.
"ASK NOC", which asks members about NOC technology, has been able to ask NOC members on a TV phone from the Android tablet this year from the conventional whiteboard system.In the past, NOC members worked at the NOC glass booth, but this time they work in the backyard room.

POD is a network relay point that provides a connection to SHOWNET.This time, it is concentrated in two places, 4 holes and 6 holes.Each POD has one rack, with switches and control devices.Furthermore, POD4 in the four holes also has a demonstration of route switching using OpenFlow.

In addition, before POD4, the connection of Ethernet is prepared, and it is a corner where you can experience Shownet access.This Ethernet cable is divided into IPv6 migration technologies such as DS-Lite, NAT64, 464XLAT, and SA64T, so you can experience each.In addition, wireless LAN is also provided for the ShowNet access.

In addition, "Network Service Center", a help desk that accepts trouble reports from exhibitors, is also operated as usual.This year, the ticket (assignment) management system that has been used for many years has been completely rewritten in the modern configuration of HTML5 + CSS + JavaScript.

If you want to know more about the above network facilities and technology, you may want to participate in the ShowNet Walking Tour.However, please note that if there are many participants, it will be a lottery.
