About SCMP
SCMP Terminology
SCMP terminology is similar to, but not identical to, existing Cisco SCE platform terminology. It is
derived from the ISG terminology, since every Cisco SCE subscriber is actually an ISG session.
•
subscriber – The client who is purchasing service from the Service Provider and is receiving the bill.
•
User – A member, employee or guest at the subscriber household or business using the service.
•
Session – A logically identifiable entity on the service gateway that represents communication with
a peer. It is based on a unique combination of one or more Identity Keys such as an IP address, a
subnet, a MAC address, a tunnel termination interface (PPP) or a port.
Each session is assigned a unique identifier.
•
Flow – Characterized by several parameters identifiable from the traffic such as source IP address,
destination IP address, source port, destination port, protocol and in some cases direction.
•
SCMP Peer – A Cisco device running IOS with the ISG module enabled.
•
Identity Key – One of the keys that help identify a Session. The identity keys that are relevant to the
Cisco SCE-ISG control-bus are:
–
IP Address/Subnet
–
IP Subnet
•
Policy – Defines all aspects of subscriber session processing. A policy consists of conditions and
actions. Traffic conditions will classify traffic and allow policing actions to be applied to the traffic.
Policies may be provisioned, updated and removed. Policies may also be activated for a session or
deactivated for a session. A policy may be referred to by name.
Deployment Scenarios
The following sections illustrate the basic types of SCMP deployment scenarios.
•
1xISG – 1xCisco SCE
•
1xISG – 2xCisco SCE (Cisco SCE cascade)
•
NxISG – 2xCisco SCE (Cisco SCE cascade)
•
NxISG – MxCisco SCE Via Load Balancing (MGSCP)
