  • Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide 1210 Goals – Dynamic and Scalable Routing  Support for AAA, QoS, mobility and charging applications – Subscriber-based routing (IMSI-HSS matching and home network resolution) – Roaming steering (preferred network selection) – IMSI-to-resource mapping – Session binding for PCRF – Route around failures – Customer-defined applications  Benefits – Enforce complex business logic – Architectural flexibility and future-proof – Easy to provision and troubleshoot – Highly scalable – Service continuity
  • Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide 1211 Goals – Interoperability and Interworking Requirement DSC Functions/Features Diameter signaling normalization  Message manipulation before and after message routing  Search and modify on any AVP (attribute value pair) Transport layer interworking  Interworking between SCTP, TCP, SCTP over IPsec, TCP over IPsec IP address interworking  Interworks IPv4 to IPv6 transport  IPv4-IPv4 bridging
  • Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide 1212 Goals – Security and Service Availability Requirement DSC Functions/Features Secure border & protect the Diameter core  Wire-speed, DDoS and access controls  Diameter signaling rate limiting  Hide topology from roaming partners  Confidentiality of roaming information  Authentication of untrusted 3rd parties Prevent unauthorized service  IMSI range blocking Ensure service availability  Integrated Diameter overload controls  Anomaly isolation - Single Diameter element cannot inadvertently interrupt service  Prevent starvation attacks Scale security  Purpose-built platforms  Integrated and scalable encryption
  • Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide 1213 Goals – Controlling Overload and Congestion Requirement DSC Functions/Features Control and monitor Diameter signaling traffic  Transaction rate policing by agent or group  Monitor upstream and downstream agent availability Increase network scale  Diameter load balancing Protect upstream devices  Message filtering  Policy based AVP forwarding and rejection by ingress/egress realm, originating host, specific AVPs  Fine grained message control based on application-id and message command-code Increase network resiliency & failure response  Agent failure detection and route-around  Report on network failures
  • Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide 1214 Goals – Visibility Centralized Network Management Monitoring and KPI Reporting • Manage large number of DSCs • Easy-to-use (GUI) • Common management for all elements • Flow-through provisioning via APIs Scalable easy- to-use management • Overload and security attacks • Diameter connection failures • Diameter agent reachability • System health events Respond to attacks, overload and failures • Comprehensive KPIs: all Diameter interfaces • Multi-level: System, Diameter interface and agent • OSS ready: CLI, HDR, SNMP Monitor network performance • Detailed transaction analysis • Capture/analysis of Diameter packets • Extensive alarm and event logging • Diameter debugging information • Reliable Diameter accounting Troubleshoot and diagnose
