MAC Address A unique address assigned to a station interface, identifying that station on the network. With Ethernet, this is the unique 48-bit station address. Same as the physical address. Megabit (Mb) Megabit. One million bits of information, usually used to express a data transfer rate ; 1 Megabit/ second = 1Mbps. Megabyte (MB) MegaByte. A unit of data storage size which represents one million characters of information. Multicast A transmission initiated by one station to many stations of the network. Port Mirroring Port mirroring allows a switch port to monitor packets from any or all of its ports so that traffic can be analysed. Quality of Service (QoS) Some switches support QoS (per 802.1p and 802.1Q standards) whereby messages can be assigned levels of priority. QoS is important where time- critical applications can be impaired by data delays. RJ45 8-position modular jacks used on twisted pair links for Ethernet cabling.

RJ-Field A wide range of connectors which allow to reinforce and seal standard RJ45 cable. See www.rjfield.com SNMP Simple Network Management Protocol. This is THE standard used for switch management programs. Spanning Tree Protocol (STP) A link management protocol providing path redundancy and preventing network loops by defining a tree to span all switches in a network. It forces redundant data paths into a standby (blocked) state. If a path malfunction occurs, the topology is reconfigured and the link reestablished by activating the standby path. TCP/IP Transmission Control Protocol/Internet Protocol. A set of protocols, resulting from ARPA efforts, used by the Internet to support services such as remote login (TELNET), file transfer (FTP) and mail (SMTP). TELNET The Internet standard protocol for remote login (terminal connection) service. TELNET allows a user at one site to interact with a remote timesharing system at another site as if the user’s terminal were connected directly to the remote computer. VLAN Virtual Local Area Network. A LAN that maps stations on a basis other than location such as by department, user type or application. Managing traffic, workstations, and bandwidth can be easier with a VLAN and improve network efficiency.
