measurable, and sometimes guaranteed services.
Achieving the required QoS becomes the secret to a successful end-to-end business solution. Therefore,
QoS is the set of techniques to manage network resources.
QoS class
Every incoming frame is classified to a QoS class, which is used throughout the device for providing
queuing, scheduling and congestion control guarantees to the frame according to what was configured
for that specific QoS class. There is a one to one mapping between QoS class, queue and priority. A QoS
class of 0 (zero) has the lowest priority.
R
RADIUS
RADIUS is an acronym for Remote Authentication Dial In User Service. It is a networking protocol that
provides centralized access, authorization and accounting management for people or computers to
connect and use a network service.
S
SHA
SHA is an acronym for Secure Hash Algorithm. It designed by the National Security Agency (NSA) and
published by the NIST as a U.S. Federal Information Processing Standard. Hash algorithms compute a
fixed-length digital representation (known as a message digest) of an input data sequence (the message)
of any length.
SMTP
SMTP is an acronym for Simple Mail Transfer Protocol. It is a text-based protocol that uses the
Transmission Control Protocol (TCP) and provides a mail service modeled on the FTP file transfer
service. SMTP transfers mail messages between systems and notifications regarding incoming mail.
SNMP
SNMP is an acronym for Simple Network Management Protocol. It is part of the Transmission Control
Protocol/Internet Protocol (TCP/IP) protocol for network management. SNMP allow diverse network
objects to participate in a network management architecture. It enables network management systems to
learn network problems by receiving traps or change notices from network devices implementing SNMP.
T
Tag Priority
Tag Priority is a 3-bit field storing the priority level for the 802.1Q frame.
