RDR
Resource Data Record
Reachable Peer
Represents a group of peers that are reachable by the node sending the Routing- Update-Request (RUR).
Realm
A fundamental element in Diameter is the realm, which is loosely referred to as domain. Realm IDs are owned by service providers and are used by Diameter nodes for message routing.
Recovered Timing Mode
This timing mode on the HC-MIM applies to Channel Bridging. The port with this mode selected uses the other member of the bridged-pair as a clock source, ensuring that both ports are using the same clock for line stability.
Receiver Window
An SCTP variable that a data sender uses to store the most recently calculated receiver window of its peer, in number of bytes. This gives the sender an indication of the space available in the receiver's inbound buffer.
REDIRECT
A function of the gateway screening commands that specifies whether messages that pass gateway screening are diverted, by the gateway screening redirect function, from its original destination to another destination for further processing.
Redirect Agent
A Diameter Redirect Agent refers clients to servers and allows them to communicate directly.
Redirect Server
A centralized database that maps subscriber numbers to routing numbers or domain names.
Redundant Rules
Rules are redundant if the PCRF Sub-Pools are the same and a request matching the more specific rule always matches the less specific rule. Redundancy does not include the default rule. The PCRF Sub-Pool Selection Rules GUI does not prevent creation of redundant rules since the PCRF Sub-Pool is the same, leaving no ambiguity.
Reference Implementation
In the software development process, a reference implementation is the standard from which all other implementations and corresponding customizations are derived.
REL
Release
Relay Agent
Diameter agent that forwards requests and responses to other Diameter nodes based on routing-related AVPs (such as Destination-Realm) and routing configuration. Because relays do not make policy decisions, they do not examine or alter non-routing AVPs. As a result, relays never originate messages, do not need to understand the semantics of messages or non-routing AVPs, and are capable of handling any Diameter application or message type.
Relay Identity
Identifies the TWAN relay identity type as either IPv4/IPv6 or FQDN.
Remote Authentication Dial-In User Service
See RADIUS
Remote BUSY Congestion
A DSR feature that limits the routing of Request messages to a Diameter connection when the Peer Node is rejecting Diameter transactions on that Diameter connection due to a BUSY condition.

Representational State Transfer
Used by the provisioning system to send HTTP requests (GET, POST, PUT) to manipulate and query data in the provisioning database.
Restricted
The network management state of a route, link set, or signaling link that is not operating properly and cannot carry all of its traffic. This condition only allows the highest priority messages to sent to the database entity first, and if space allows, followed by the other traffic. Traffic that cannot be sent on the restricted database entity must be rerouted or the traffic is discarded.

Route
A signaling path from an LSP to an RSP using a specified Link Set.
Route Group
A set of peers that have the same priority within a route list.
Route List
A prioritized set of Route Groups used for routing Diameter Request messages. Only one route group within a route list is used for routing messages at any point in time, and is called the active route group. A route list is selected by a peer routing rule for routing a Diameter Request message to an upstream peer.
Route Set
A group of routes, no more than six, carrying traffic to the same destination.
Routing Entity
A User Identity or an IP Address associated with the User Equipment (IPv4 or IPv6 address).
Routing Key
A set of SS7 parameter and parameter values that uniquely define the range of signaling traffic to be handled by a particular Application Server. For example, where all traffic directed to an SS7 DPC, OPC, and ISUP CIC_range(s), or SCCP SSN is to be sent to a particular Application Server, that SS7 data defines the associated Routing Key.
Routing Option Set
A set of user-configurable routing options that a can be associated with a Diameter transaction based on the downstream Peer Node from which the transaction was received or the Diameter Application ID in the ingress transaction.

RSR
Reset Request
Route Set Test. Restricted message.
RST
Route Set Test
Route Set Prohibited Test (Msg). Signaling-route-set-test signal for prohibited destination.
RSTP
Rapid Spanning Tree Protocol
Adding redundant links to a network increases availability; unfortunately, it can also spawn network traffic loops. Traffic loops can overburden hosts and result in unpredictable network performance. RSTP addresses redundancy requirements, but at the same time, it works to detect and prevent traffic loops that may develop in the network.

RU
Rack Unit
One rack unit (1RU) is 44.45 mm (1.75 in) high.
RUA
Routing Update Answer
DRMA protocol messages sent between Policy Management systems.
Rule
An association between a Filter and an Action Set.
Rule Condition
Each PCRF Sub-Pool Selection Rule consists of a condition made up of a parameter (Origin-Host), an operator, and a value. An example Condition might look like: Origin-Host Equals pcef015.tklc.com.
Rule Matching
Rule matching is the process of finding the best match among the configured PCRF Sub-Pool Selection Rules for a given binding capable session initiation request. Rule matching occurs on the DA-MP that processes the binding capable session initiation request.
Rule Priority
Each PCRF Sub-Pool Selection Rule has a priority value from 1 to 99, with 1 being the highest priority. The Rule Priority allows the user to give preference to one rule over another, regardless of which rule might be the “best match.”
RUR
Routing Update Request
DRMA protocol messages sent between Policy Management systems.
RWND

RX
Receive
The Diameter interface between a PCRF and an Application function (AF) such as a PCSCF, as defined by 3GPP. The Rx interface uses AAR/AAA, RAR/RAA, STR/STA, and ASR/ASA messages and is binding dependent.
