TOE components are incorporated into one of the printed circuit boards, such as the network interface card (NIC) or the host bus adapter (HBA). In recent years, the communication speed in Ethernet systems has increased faster than computer processor speed. This produces an input/output (I/O) bottleneck. The processor, which is designed primarily for computing and not for I/O, cannot keep up with the data flowing through the network. As a result, the TCP/IP flow is processed at a rate slower than the speed of the network. TOE solves this problem by removing the burden (offloading) from the microprocessor and I/O subsystem. The manner in which TOE is implemented depends on the needs of the customer. Considerations include flexibility, scalability, and performance. Network performance and scalability are optimized with application-specific integrated circuit (ASIC) implementation. Network flexibility is optimized with processor-based implementation. _______________________ RELATED TERMS: Ethernet http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci212080,00.html?track=NL-34 throughput http://whatis.techtarget.com/definition/0,,sid9_gci213140,00.html?track=NL-34 network interface card http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci212660,00.html?track=NL-34 processor http://whatis.techtarget.com/definition/0,,sid9_gci212833,00.html?track=NL-34 application-specific integrated circuit http://whatis.techtarget.com/definition/0,,sid9_gci213785,00.html?track=NL-34 ______________________ SELECTED LINKS: The 10 Gigabit Ethernet Alliance (10GEA) explains how TOE works. http://www.10gea.org/SP0502IntroToTOE_F.pdf SearchNetworking.com offers links to white papers about TCP/IP and related technologies. http://searchnetworking.techtarget.com/whitepapers4/0,293835,sid7,00.html?track=NL-34 ______________________ TODAY'S TECH NEWS: NOVELL TO ACQUIRE SUSE LINUX Novell said it plans to acquire SuSE Linux, the second largest open source server software provider, in a $210 million cash deal. http://searchenterpriselinux.techtarget.com/originalContent/0,289142,sid39_gci935175,00.html?track=NL-34 MICROSOFT'S WLAN PLAY CHANGES GAME Microsoft's arrival in the wireless LAN management space with a product that simplifies Wi-Fi deployment and setup is evidence that not only is the software giant looking to expand its presence in the enterprise, but it's also looking to push smaller vendors out of the market. http://searchmobilecomputing.techtarget.com/originalContent/0,289142,sid40_gci935203,00.html?track=NL-34 MICROSOFT LOCKS DOWN INTELLECTUAL PROPERTY Microsoft today released Windows Rights Management Services, a security component for Windows Server 2003 that aims to protect enterprise intellectual property. http://searchwin2000.techtarget.com/originalContent/0,289142,sid1_gci935174,00.html?track=NL-34 >> Catch up on all the latest IT news at http://searchtechtarget.techtarget.com?track=NL-34 ______________________ SECRET WORD-OF-THE-DAY | What is IT?
