Net One Systems Co., Ltd.
commences sales of Lantern Communications' RPR Switch to provide MAN optimized RPR over 10GbE solution

Net One Systems ("Net One"; headquarters: Shinagawa, Tokyo, President & CEO: Kazuo Sato), having entered into a reseller agreement with Lantern Communications, Inc. ("Lantern"; headquarters: California), announces its resell business, starting as of June 19, 2002, for the first time in Japanese market. RPR (Resilient Packet Ring) technology is scalable from Ethernet LAN to MAN while ensuring SONET-level fault tolerance and capable of delivering packet-based metro ring networks.
Lantern's RPR Switch serves as a RPR solution with the wide-bandwidth provisioning of 10GbE ring interfaces. Lantern makes a flexible QoS service over Ethernet happen through the L4, not just L2, bandwidth control technology (QoS) and the unique Tiered Protection architecture, allowing users to select arbitrary protection rate from 0% to 100%.
The product is the fruit of the integration endeavor of two different capabilities, LAN's switching and WAN's transmission, into one machine; the product employs both of LAN's advantages, such as VLAN feature, and of WAN's benefit of reliability, with the objective to create the new network architecture: one machine to seamlessly connect metro to core LAN-WAN access.
Leveraging the introduction of Lantern's RPR Switch, Net One is ready to provide an innovative RPR solution to deliver the low-cost MAN-optimized network deployment while enhancing Ethernet's reliability to the level of carrier's requirement.

■Maximum use of RPR, the next generation standard technology

RPR retains both prominent features of Ethernet, which offers high cost-performance and ability to support wide area, and also features of SONET, which provides reliability. RPR is an innovative transmission technology that delivers fair allocation of ring bandwidth, physical pathway that is individually determined for each packet, and dramatic increase in effective usage of ring bandwidth through packet strip (special reuse) by address node. In effect, RPR is the promising technology of the coming generation; while overcoming the conventional shortcomings and retaining the advantages of Ethernet, it enhances reliability and improves performance.
Lantern is a core member of the RPR working group IEEE802.17 and supports RPR standardization, which is expected to complete by June 2003.
Furthermore, by including proprietary technologies as L2-L4 QoS, and arbitrary selection of protection rate, Lantern's RPR switch provides performance guarantee and in an event of failure, bandwidth guarantee. This allows maximum usage of bandwidth while conforming to SLA rather than on best effort basis.

■MPSs (Metropolitan Packet switch System) that may be selected based on network scale

• Ring interface modules that support 10GbE
• By allocating dual rings for signal transmission during normal operation, bandwidth usage is over twice that of SONET.
• SONET/SDH class reliability (restoration less than 50msec)
• L2-L4 QoS
• provides selection of 0% to 100% protection rate (Tiered Protection)
• Supports 802.1Q VLAN, Virtual Bridge
• Cost reduction through end to end Ethernet connection

*MPS−AX
・14 slots /　Supports GbE x16（FE x 128）
*MPS−FX　
・6 slots　/　Supports GbE x 4 ( FE x 32 )

■Prospective Customers

Carriers, ISPs, Data Centers, Large companies, local government institutions, universities, research institutions, industrial plants, etc.
