RMON
Remote Monitoring. RMON provides standard information that a network
administrator can use to monitor, analyze, and troubleshoot a group of dis-
tributed LANs.
RoW
Rest of World. RoW or RW is an operating country code of a device.
RSA
Rivest, Shamir, Adleman. RSA is a cryptosystem for public-key encryption,
and is widely used for securing sensitive data, particularly when being sent
over an insecure network such as the Internet.
RSSI
Received Signal Strength Indicator. RSSI is a mechanism by which RF ener-
gy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not
standard across vendors. Each vendor determines its own RSSI
scale/values.
RSTP
Rapid Spanning Tree Protocol. RSTP provides significantly faster spanning
tree convergence after a topology change, introducing new convergence
behaviors and bridge port roles to do this.
RTCP
RTP Control Protocol. RTCP provides out-of-band statistics and control in-
formation for an Real-Time Transport Protocol session.
RTLS
Real-Time Location Systems. RTLS automatically identifies and tracks the
location of objects or people in real time, usually within a building or other
contained area.
RTP
Real-Time Transport Protocol. RTP is a network protocol used for delivering
audio and video over IP networks.
RTS
Request to Send. RTS refers to the data transmission and protection mecha-
nism used by the 802.11 wireless networking protocol to prevent frame colli-
sion occurrences. See CTS.
RTSP
Real Time Streaming Protocol. RTSP is a network control protocol designed
for use in entertainment and communications systems to control streaming
media servers.
RVI
Routed VLAN Interface. RVI is a switch interface that forwards packets be-
tween VLANs.
RW
Rest of World. RoW or RW is an operating country code of a device.
SA
Security Association. SA is the establishment of shared security attributes
between two network entities to support secure communication.
SAML
Security Assertion Markup Language. SAML is an XML-based framework for
communicating user authentication, entitlement, and attribute information.
SAML enables single sign-on by allowing users to authenticate at an identity
provider and then access service providers without additional authentication.
SCEP
Simple Certificate Enrollment Protocol. SCEP is a protocol for requesting and
managing digital certificates.
SCP
Secure Copy Protocol. SCP is a network protocol that supports file transfers
between hosts on a network.
SCSI
Small Computer System Interface. SCSI refers to a set of interface standards
for physical connection and data transfer between a computer and the pe-
ripheral devices such as printers, disk drives, CD-ROM, and so on.
SDN
Software-Defined Networking. SDN is an umbrella term encompassing sev-
eral kinds of network technology aimed at making the network as agile and
flexible as the virtualized server and storage infrastructure of the modern
data center.
