The Type of Service (ToS) octet in the IPv4 header includes three

precedence bits defining eight different priority levels ranging from highest
priority for network control packets to lowest priority for routine traffic. The
eight values are mapped one-to-one to the Class of Service categories by
default, but may be configured differently to suit the requirements for
specific network applications.

INK GGREGATION
MD5 Message-Digest is an algorithm that is used to create digital
MD5
signatures. It is intended for use with 32 bit machines and is safer than the
MD4 algorithm, which has been broken. MD5 is a one-way hash function,
meaning that it takes a message and converts it into a fixed string of digits,
also called a message digest.
Management Information Base. An acronym for Management Information
MIB
Base. It is a set of database objects that contains information about a
specific device.
A process whereby the switch filters incoming multicast frames for services

for which no attached host has registered, or forwards them to all ports
contained within the designated multicast VLAN group.
Multicast VLAN Registration is a method of using a single network-wide
MVR
multicast VLAN to transmit common services, such as such as television
channels or video-on-demand, across a service-provider's network. MVR
simplifies the configuration of multicast services by using a common VLAN
for distribution, while still preserving security and data isolation for
subscribers residing in both the MVR VLAN and other standard or
private VLAN groups.
