TOKYO--April 8, 2010--Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI, TSE1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced it has received approval in both Japan and the U.S.A. for patents on SMFv2, IIJ's proprietary next-generation network management framework.

Patent Description


Patent Number 4463868
Title of invention Network connecting appliance management system
Date of issue February 26, 2010


Patent Number 7660266
Title of invention Automatic functionality generating mechanism for network connecting appliances
Date of issue February 09, 2010

SMFv2 was developed from the network management framework SMF patented in 2003 (patent 3774433). SMF technology enables the centralized management--including initialization and re-configuration--of IIJ's proprietary SEIL routers. SMFv2 takes this technology a step further by enabling the same level of centralized management for network devices produced by other companies.
The acquisition of these patents is testimony to the unique qualities of this system in both the U.S.A. and Japan. These qualities include the following:

Wider range of compatible equipment

SMFv2 can centrally manage other network devices in addition to the SEIL series of routers. By installing the automatic connection library, provided free of charge by IIJ, equipment can automatically connect to the network and be centrally managed, whether they are home appliances, server equipment for cloud services, or other devices that connect to a network.

Extensible functions and applications

SMFv2 contains an auto-generation function that transfers new functions to the equipment being managed. In addition to simply managing the device, the user can now add or delete whatever functions or applications are needed. This feature allows network devices to get the most out of limited hardware resources and enables these same network devices to perform as a cloud service cache, load balancer, protocol accelerator, and other accelerator-type devices.

SMFv2 is already providing the system infrastructure for IIJ's SOHO Ethernet service LaIT Private Ether and NEC Networks & System Integration Corporation's WAN solution SASDAKE.

IIJ also acquired a patent on its SMF-LAN, which enables the centralized management of network equipment using SMF over wide-area Ethernet and other closed networks. IIJ will continue to develop new technologies that use SMF to promote the use of SMF to a wider range of users.
