700 Series Managed Switch User's Guide for Software v2.1 Filtering The process of screening a packet for certain characteristics, such as source address, destination address, or protocol. Filtering is used to determine whether traffic is to be forwarded, and can also prevent unauthorized access to a network or network devices. Flow control A congestion- control mechanism. Congestion is caused by devices sending traffic to already overloaded port on a switch. Flow control prevents packet loss and temporarily inhibits devices from generating more traffic until the period of congestion ends. Full-duplex A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link. Gateway A local device, usually a router, that connects hosts on a local network to other networks. Gigabit Ethernet An Ethernet system that is designed to operate at 1000 Mbps (1 Gbps). Half-duplex A system that allows packets to transmitted and received, but not at the same time. Contrast with full-duplex. IEEE Institute of Electrical and Electronics Engineers. This American organization was founded in 1963 and sets standards for computers and communications. IETF Internet Engineering Task Force. An organization responsible for providing engineering solutions for TCP/ IP networks. In the network management area, this group is responsible for the development of the SNMP protocol. IGMP Internet Group Management Protocol, the standard for IP multicasting in the Internet. IGMP is used to establish host memberships in multicast groups on a single network. (See IP multicast) IP Internet Protocol is the main internetworking protocol used in the Internet. Used in conjunction with the Transfer Control Protocol (TCP) to form TCP/IP. IP Address A four-byte number uniquely defining each host on the Internet, usually written in dotted-decimal notation with periods separating the bytes (for example, 134.177.244.57).
