Appendix: Glossary 802.3ae - The IEEE standard for 10 Gigabit Ethernet over fiber 802.3ak - The IEEE standard for 10 Gigabit over coaxial cable 802.3an - The IEEE standard for 10GBASE-T copper twisted pair 802.3ab - The IEEE standard for UTP Gigabit Ethernet (1000BASE-T) 802.3z - The IEEE standard for Gigabit Ethernet (1000BASE-X) Cat 6 - Currently defined in TIA/EIA-568-B. Provides performance of up to 250 MHz, more than double category 5 and 5e. Cat 6a - Currently defined in ANSI/TIA/EIA-568-B.2-10. Provides performance of up to 500 MHz, double that of category 6. Suitable for 10GBase-T. Cat 7 - An informal name applied to ISO/IEC 11801 Class F cabling. This standard specifies four individually-shielded twisted pairs (STP) inside an overall shield. Designed for transmission at frequencies up to 600 MHz. Edge servers - Servers that are located closer to end user machines than to origin servers at the backbone of the network. An example of an edge server would be a cache server distributing frequently requested pages. Congestion Notification -- Provides end to end congestion management for protocols that do not already have congestion control mechanisms built in FDDI - Fiber Distributed Data Interface is a standard is a standard for LANs with a maximum distance of 124 miles Gbps - Gigabits per second or billion bits per second IEEE - Institute of Electrical and Electronics Engineers IP - Internet Protocol IPC - Interprocess Communications IPC Semaphores -- IPC objects that are used for synchronization. iSCSI initiator - The application server running an iSCSI stack (software or hardware), requesting access to storage. iSCSI target - The device through which the initiator can access the storage. ISO - International Standards Organization LAN - Local Area Network Media Access Control (MAC) - The media access control sublayer provides a logical connection between the MAC clients of itself and its peer station. Its main responsibility is to initialize, control, and manage the connection with the peer station. The MAC layer of the 10 Gigabit protocol uses the same Ethernet address and frame formats as other speeds, and will operate in full-duplex mode. It will support a data rate of 10 Gbps using a pacing mechanism for rate adaptation when connected to a WAN-friendly PHY. LR - Fiber cable standard for "long range" over single mode cabling LRM- Fiber cable standard for "long reach multimode" over multimode cabling MAN - Metropolitan Area Network Mbps - Megabits per second or million bits per second MMF - Multimode Fiber 14
