per-hop behavior, at each network node.
of service to users on the network with mechanisms such as traffic meters,
shapers/droppers, packet markers at the boundaries of the network.
Differentiated Services Code Point Service (DSCP)
DSCP uses a six-bit tag to provide for up to 64 different forwarding
behaviors. Based on network policies, different kinds of traffic can be
marked for different kinds of forwarding. The DSCP bits are mapped to
the Class of Service categories, and then into the output queues.
Domain Name Service (DNS)
A system used for translating host names for network nodes into IP
addresses.
Dynamic Host Control Protocol (DHCP)
Provides a framework for passing configuration information to hosts on a
TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP),
adding the capability of automatic allocation of reusable network addresses
and additional configuration options.
Extended Universal Identifier (EUI)
An address format used by IPv6 to identify the host portion of the
network address. The interface identifier in EUI compatible addresses is
based on the link-layer (MAC) address of an interface. Interface identifiers
used in global unicast and other IPv6 address types are 64 bits long and
may be constructed in the EUI-64 format. The modified EUI-64 format
interface ID is derived from a 48-bit link-layer address by inserting the
hexadecimal number FFFE between the upper three bytes (OUI field) and
the lower 3 bytes (serial number) of the link layer address. To ensure that
the chosen address is from a unique Ethernet MAC address, the 7th bit in
the high-order byte is set to 1 (equivalent to the IEEE Global/Local bit) to
indicate the uniqueness of the 48-bit address.
