Overview of Cisco Carrier Sensitive Routing

CSR Basics

CSR evaluates the predetermined selection and rejection criteria as part of the source carrier and DNIS information to determine what routing information to return to the gatekeeper.

Note CSR can operate with multiple gatekeepers. CSR passes through the ANI, but its work is not based on the ANI. If the CSR receives the destination carrier, it passes the call through with the same information that it receives.

PostgreSQL Database

The postgreSQL database stores all the provisioned data associated with the CSR. The data can be entered into the database by using the GUI or by importing. The database supports active dataset, inactive dataset, and configuration data.

Information contained in the active and inactive datasets includes:

•Carrier Table—Contains a list of carriers and associated attributes.

•Contact List Table—Contains a relationship of contacts to a key.

•Contacts Table—Contains a list of RAS addresses (zones) and associated attributes.

•Egress Route Attributes Table —Contains a list of egress attributes and associated data.

•Egress Routes Table —Contains a list of egress attributes and associated routes.

•Ingress Route Attributes Table—Contains a list ingress attributes and associated data.

•Ingress Routes Table—Contains a list of ingress attributes and associated routes.

•Match Patterns Table—Contains a list of match patterns and associated routes.

•QoS Table—Contains a list of relative QoS values associated to route, ingress, and egress.

•Routes Table—Contains a list of routes and associated rules.

•Rules Table—Contains a list of rules and associated attributes (selection/rejection). Configuration data contained in the database includes:

•Gatekeepers Table—Contains a list of gatekeepers and associated registration messages.

•Filters Table—Contains a list of gatekeepers and associated filters.

•Configuration Settings Table—Contains logging level, application priority, incoming connection port and test routes accounting flag.

•TestRoutes —A record is added to this when a test route command is issued.

•TestOutputs—A set of records is added to this table after the test route command is complete.

•LogEntries—A set of records is added to this table after the test route command is complete.

•StringResources—Logging strings are located here.

CSR Application

The CSR application contains the logic (selection and rejection) to determine the proper routing for calls based on inputs from the gatekeeper. CSR operates by the rules described in the following section.
