Appendix: Glossary

802.3ae – The IEEE standard for 10 Gigabit Ethernet over fiber
802.3ak – The IEEE standard for over coaxial cable
10 Gigabit
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
