Starent Networks Proprietary and Confidential 4 Flow-based Traffic Policing Permit the defined policies to implement: Access Control decisions QOS decisions Accounting decisions Generally defined as: Policyclass map, policy map, and policy group Conditionsource/destination address or source/destination port etc ActionFlow classification, QOS processing, and DSCP marking

Starent Networks Proprietary and Confidential 5 PaDIRT Proposed Profile IDs and DSCPs

Starent Networks Proprietary and Confidential 6 Class Map Configured on a per-subscriber basis either locally on the system or on a remote RADIUS server Class Map: Match packet based on: Source/destination ip address IP TOS field Protocol Source/destination port number or range of port numbers Packet size Created in the egress context 32 Class Maps per egress context can be configured Set to match all or any of the classification rules

Starent Networks Proprietary and Confidential 7 Class Map Example class-map name VOIP match-any match dst-port-range 2222 to 3333 match protocol udp match protocol tcp match src-ip-address /24 match dst-ip-address /24

Starent Networks Proprietary and Confidential 8 Policy Map Policy Maps: Access control (allow or discard) Qos traffic policing (cdr, pdr, cbs, with exceed and violate actions) Qos encapsulation header DSCP Marking (0x00 – 0x3f) Type (static or dynamic) Static type (the traffic flow classification and treatment is pre- defined with classification rules in the class map) Dynamic type (is based on Rev. A flows) Class Maps are assigned to Policy Maps Created in the egress context 32 Policy Maps per egress context can be configured

Starent Networks Proprietary and Confidential 9 Policy Map Example policy-map name signal class-map VOIP type dynamic three-gpp2 rev-A profile-id id 257 flow-id any qos encaps-header dscp-marking 0x2e qos user-datagram dscp-marking 0x2e policy-map name bearer class-map VOIP type dynamic three-gpp2 rev-A profile-id id 256 flow-id any qos encaps-header dscp-marking 0x2e qos user-datagram dscp-marking 0x2e

Starent Networks Proprietary and Confidential 10 Policy Group Policy Groups: Direction (in or out) Precedence (if a session flow matches multiple policies this key word will resolve them. A range from 1 to 16 can be assigned) Policy Maps are assigned to Policy Groups Created in the egress context 16 Policy Maps per Policy Group can be configured

Starent Networks Proprietary and Confidential 11 Policy Group Example policy-group name VOIP-QoS policy signal precedence 1 policy bearer precedence 2

Starent Networks Proprietary and Confidential 12 Subscriber Default Example subscriber default authorized-flow-profile-id 256 direction bidirectional authorized-flow-profile-id 257 direction bidirectional policy-group VOIP-QoS direction in policy-group VOIP-QoS direction out
