What is ShowNetWhat is ShowNet
• INTEROP § Tradeshow of the network equipments.§ Conference and exhibition§ Since 1986 at US, 1994 at Japan
• ShowNet§ Provides the Internet connectivity to the
exhibitor’s booth.§ Demonstration on inter-operability among the
advance network equipments.

ShowNet JapanShowNet Japan
• ShowNet at Japan has been demonstrating since 1994, starting with INTEROP Tokyo.
• First 4 years, Network was designed as single design for the world wide INTEROP shows.
• From ‘98, ShowNet has been designing and implementing by the domestic NOC team with contributors from Japan and US.
• iLab of INTEROP US is wreck of a Old ShowNet.

Topics and result of ShowNet2002
Topics and result of ShowNet2002
• Interoperability on 10Gbit Ethernet§ Juniper M160, Cisco GSR, Foundry BigIron15000 and Extreme
Black diamond were satisfy the inter-operability with 10GbE LR as backbone network.
§ 1000BaseSX were provided to the exhibitors, And several different switches were used at exhibitors side. But we did not have any trouble on 1000BaseSX.
• IPv4 Multicast streaming with 35Mbps DVTS§ Every backbone routers and Hitachi GR, and all backbone L2
switches could handle the several DVTS multicast streaming.
• Interoperability on OC-192 SONET as Externel Link§ OC-192 SONET are interoperable among Juniper M160, Cisco
GSR and Fujitsu GEO 900.

Brief History of the IPv6 on ShowNet: Early Stage
Brief History of the IPv6 on ShowNet: Early Stage
• 1997-1998• PC based IPv6 routers, no commercial
routers• Separate network from IPv4 Network, because
L2 switches could not handle the IPv6 packets• # of exhibitors connected via IPv6: 3 to 5

Brief History of the IPv6 on ShowNet; Second Stage
Brief History of the IPv6 on ShowNet; Second Stage
• 1999-2001• Shared L2 networks by IPv4 and IPv6 using
VLAN.• There were IPv4/IPv6 Dual stack routers and
switches. BUT:§ Sufficient number of the routers.§ Interoperability ?
• Provided IPv6 connectivity to the every booth.

ConclusionConclusion
• ShowNet Japan 2002 is first largest demonstration of the IPv4/v6 Dual stack networks as single plain network with about 8 router and switches vendors, over the 15 equipments.
• We can believe that IPv4/v6 Dual stack networks is very helpful for the operation and management for futre network.
