protocols, CLI, network management interfaces, code storage, logging, chassis management. 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 for 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

S
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 call 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.
