QFP Cisco Quantum Flow Processor. One of Cisco-developed network processors on the Cisco

ASR1000-ESPs

RP The Cisco ASR 1000 Series RP1, route processor. General purpose CPU responsible for routing

protocols, CLI, network management interfaces, code storage, logging, chassis m anagement. The ASR

1000 Series RP1 processes network control packets as well as protocols not supported by the ASR 1000

Series ESP.

RPBase

sub-package

The sub-package responsible for providing the operating system software f or the Route Processor.

RPControl

sub-package

The sub-package responsible for providing the control plane processes between the IOS process and

the rest of the router.

RPACCESS

sub-package

The sub-package responsible for the processing of restricted components such as security features.

RPAccess K9 ASR1000rp1-rpaccessk9.pkg. The crypto RPAccess image. This is the RPAccess sub-package in

consolidated packages that support crypto.

RPIOS sub-package The sub-package responsible for storing and running Cisco IOS feat ures.

RU Rack Unit. A rack unit is 1.76 inches

SBC Cisco Session border controller. The SBC is a session-aware device which controls access to voice over

IP (VoIP) and other types of primarily media-related networks. The primary purpose of an SBC is to

protect the interior of the network from excessive call load and malicious traffic. Cisco Session Border

Controller protocol implementation performs the voice and video gateway functions simultaneously

with regular IP data services.

SBE Signaling border element. Represents the signaling agent of the SBC to handle all call processing

through SIP or H.323 protocols and in general performs the cal l control functions. An SBE typically

controls one or more media gateways.

Serial Link A single transmit and receive serial pair running initially at 1.25Gbits giving a payload of 1.0Gbits,

with future scalability to 3.125 Gbits giving a payload of 2.5 Gbits.

SFP Small form-factor pluggable (SFP) optical transceivers to provide network connectivity. An SFP

module is a transceiver device that mounts into the front panel to provide network connectivity.

SLA Service Level Agreement. The contract between a service provider and the customer that specifies the

level of service provided.

SIP (SBC) Session initiation protocol. VoIP signaling protocol.
