nViewGuide.book Page 27 Wednesday, April 5, 2006 12:33 PM NVIDIA ForceWare Networking Administrator’s Guide C H A P T E R NVIDIA TCP/IP ACCELERATION TECHNOLOGY About NVIDIA TCP/IP Acceleration Technology The NVIDIA TCP/IP Acceleration is a networking solution that includes both a dedicated processor for accelerating networking traffic processing and hardware-optimized software. NVIDIA TCP/IP Acceleration provides deep levels of networking and traffic inspections at full-duplex gigabit Ethernet speeds.
nViewGuide.book Page 28 Wednesday, April 5, 2006 12:33 PM Chapter 3 NVIDIA TCP/IP Acceleration Technology Reduced CPU Utilization In traditional networking environments, inspecting packets is laborious and affects CPU overhead, memory bandwidth, and overall system latency (Figure 3.1). For example, packets move from MAC to driver; from driver to stack within kernel space; and from stack to application, crossing the kernel-space/ user-space boundary.
nViewGuide.book Page 29 Wednesday, April 5, 2006 12:33 PM NVIDIA ForceWare Networking Administrator’s Guide The NVIDIA TCP/IP Acceleration processes all the relevant protocol headers and validates them against the list of allowed connections and the most recent connection state so that only valid packets are accepted from (or allowed onto) the network.
nViewGuide.book Page 30 Wednesday, April 5, 2006 12:33 PM Chapter 3 NVIDIA TCP/IP Acceleration Technology Notes and Warnings Note: NVIDIA TCP/IP Acceleration functionality is disabled by default. When TCP/IP acceleration is enabled, all TCP/IP connections will be offloaded. WARNING: If you have a software firewall installed on your system, enabling NVIDIA TCP/IP Acceleration technology may cause some network traffic to bypass your firewall.

Text in bold “code” font (bold code font) indicates text you type on your computer.
nViewGuide.book Page 42 Wednesday, April 5, 2006 12:33 PM Chapter 6 Using The NVIDIA Command Line Interface (nCLI) • Group parameters, such as Group get is useful in that you can view the value of all parameters inside a group with one command. • Namespace parameters are a collection of tables and other parameters. Namespace is a way to group parameters. You can only browse into a namespace. No Set or Get commands are allowed on namespace parameters.
nViewGuide.book Page 43 Wednesday, April 5, 2006 12:33 PM NVIDIA ForceWare Networking Administrator’s Guide nCLI automatically enters interactive mode. When this command completes, you will exit to the command prompt. Using Single Parameters Get and Set are the two most frequently used nCLI operations. • Get is used to retrieve the setting of a parameter and can be invoked on single, group, and table parameters. • Set is used to change or update the current setting of a parameter.

nViewGuide.book Page 106 Wednesday, April 5, 2006 12:33 PM Appendix C Glossary A P P E N D I X GLOSSARY • distinguished name. In reference to the ForceWare Network Access Manager application, a distinguished name is the name that uniquely identifies a parameter. Each parameter has a distinguished name. • group parameter.

nViewGuide.book Page 107 Wednesday, April 5, 2006 12:33 PM NVIDIA ForceWare Networking Administrator’s Guide Because a message is divided into a number of packets, each packet can, if necessary, be sent by a different route across the Internet. Packets can arrive in a different order than the order in which they were sent. The Internet Protocol just delivers them. For applications requiring in-order delivery, it's up to a higher-layer protocol to ensure proper sequencing across a packet stream.

nViewGuide.book Page 109 Wednesday, April 5, 2006 12:33 PM NVIDIA ForceWare Networking Administrator’s Guide • UDP (User Datagram Protocol) is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the IP. UDP is an alternative to the TCP and, together with the IP, is sometimes referred to as UDP/IP. Like the TCP, the UDP uses the IP to actually get a data unit (called a datagram) from one computer to another.
