QoS
Quality of Service (QoS) is a method to guarantee a bandwidth relationship
between individual applications or protocols.
A communications network transports a multitude of applications and data,
including high-quality video and delay-sensitive data such as real-time voice.
Networks must provide secure, predictable, 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.
R
RARP
Reverse Address Resolution Protocol (RARP) 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
Remote Defect Indication (RDI) is an OAM functionality that is used by a MEP to
indicate defect detected to the remote peer MEP
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 being backwards-compatible with
STP.
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.
