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
RARP
RARP is an acronym for Reverse Address Resolution Protocol. It is a protocol that is used to obtain an IP address for a
given hardware address, such as an Ethernet address. RARP is the complement of ARP.
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.
RDI
RDI is an acronym for Remote Defect Indication. It is a OAM functionallity that is used by a MEP to indicate defect
detected to the remote peer MEP
Router Port
A router port is a port on the Ethernet switch that leads switch towards the Layer 3 multicast device.
RSTP
In 1998, the IEEE with document 802.1w introduced an evolution of STP: the Rapid Spanning Tree Protocol, which
provides for faster spanning tree convergence after a topology change. Standard IEEE 802.1D-2004 now incorporates
RSTP and obsoletes STP, while at the same time being backwards-compatible with STP.
S
SAMBA
Samba is a program running under UNIX-like operating systems that provides seamless integration between UNIX and
Microsoft Windows machines. Samba acts as file and print servers for Microsoft Windows, IBM OS/2, and other SMB
client machines. Samba uses the Server Message Block (SMB) protocol and Common Internet File System (CIFS),
which is the underlying protocol used in Microsoft Windows networking.
Samba can be installed on a variety of operating system platforms, including Linux, most common Unix platforms,
OpenVMS, and IBM OS/2.
