InterWorking Labs is a privately owned company in Scotts Valley, California, in the business of optimizing application performance for applications and embedded systems. Founded in 1993 by Chris Wellens and Marshall Rose, it was the first company formed specifically to test network protocol compliance. Its products and tests allow computer devices from many different companies to communicate over networks. ==Products== InterWorking Labs' Products diagnose, replicate, and re-mediate application performance problems. The company's first product, SilverCreek, tests a Simple Network Management Protocol (SNMP) agent implementation (switch, server, phone) with hundreds of thousands of individual tests, including conformance, stress, robustness, and negative testing. The tests detect and diagnose implementation errors in private and standard MIBs as well as SNMPv1, v2c, and v3 stacks and implementations.〔 The Maxwell family products emulate real world networks, with problems such as delays, rerouting, corruption, impaired packets or protocols, Domain Name System delays or limited bandwidth. New impairments are added to Maxwell using C, C++, or Python extensions. It is controlled via graphical, command line, and script interfaces. It supports a set of protocol impairments for TCP/IP, DHCP, ICMP, TLS, and SIP testing.〔 The Maxwell products are named after Maxwell's Demon, a thought experiment by 19th century physicist James Clerk Maxwell. Maxwell’s Demon demonstrated that the Second Law of Thermodynamics—which says that entropy increases—is true only on average. In his thought experiment, Maxwell imagined a double chamber with a uniform mixture of hot and cold gas molecules. A demon (some intelligent being) sits between the two chambers operating a trap door. Every time a cold (low-energy) molecule comes by, the demon opens the door and lets the molecule through to the other side. Eventually, the cold gas molecules are all on one side of the chamber and the hot ones all on the other. Although the molecules continue to move randomly, the introduction of intelligence into the system reduces entropy instead of increasing it. The Maxwell product sits in the middle of a network conversation and opens or closes a figurative "door" on the basis of specific criteria. Maxwell intelligently modifies the packet based on pre-selected criteria and sends the packet on its way.〔 InterWorking Labs is advised by the Internet Engineering Task Force (IETF). Maxwell's network emulations reproduce real conditions in the lab before products are deployed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「InterWorking Labs」の詳細全文を読む スポンサード リンク
