  7. AAA Server --> Standards Supported RFC 2138 Remote Authentication Dial In User Service (RADIUS) RFC 2139 RADIUS Accounting RFC 2865 Remote Authentication Dial In User Service (RADIUS) RFC 2866 RADIUS Accounting RFC 2869 RADIUS Extensions 3GPP2 P.S0001-B cdma2000 Wireless IP Network Standard RFC 3588 Diameter based Protocol RFC 4006 Diameter Credit Control Application

  8. AdvOSS Service ControlAAA Server --> AAA Applications AAA Applications: Each AAA request is handled by a respective AAA Application that interfaces with different functions in core network over multiple interfaces.

  9. Authentication use cases • Automatic Authentication (MAC based) • Managing the policy of the basis of Authentication • Multiple successive Authentications from different network elements • Providing device Exculsivity • Control of Mobility • Identity Theft Protection • Account Sharing Prevention and Allowance • Load Sharing among VLANs • Lawful Intercept • CPE Sharing

  10. Authorization use cases • Service Request Authorization • Re-Authorization and Quota Reservation • Concurrency Authorization • Capability Authorization for multiple services • Quality of Service (QoS) and Quality of Experience (QoE)Authorization • Interconnect or terminating side capacity control

  11. AdvOSS Policy Server Compliant with industry standard functionality specified by olicy and Charging Rules Function (PCRF) It is at the heart of any modern day service provider’s core network and allows to define rules that govern the way services are delivered and charged

  12. Policy Management AdvOSS Policy Server includes a rule based engine along with options for: • Bandwidth Management • QoS Management • Charging Management • Advanced Rule Based Actions

  13. Quotas • AdvOSS Policy Server also includes a quota manager that allows counting of usage by individual subscribers. • Allows to fulfill many important use cases.

  14. Volume Caps AdvOSS PCRF allows a Service Provider to create subscriptions that have bundled volume caps e.g. • 1MB-10GB • 1MB-Unlimited volume

  15. Fair-Usage AdvOSS PCRF allows a service provider to define fair-usage policies. Once a user goes beyond its usage threshold(s), fair-usage actions can kick-on. They may be: • Bandwidth throttling • Start of Charging • Service Denial

  16. Fair-Usage • Bandwidth throttling

  17. Fair-Usage • Start of Charging

  18. Fair-Usage • Service Denial

  19. Time Based Quotas AdvOSS PCRF allows to define time based packages where the usage is only counted during specific periods of the day allowing defining of packages like: 1MB – 5GB with unlimited usage from 2:00am to 8:00am

  20. Advanced Quotas AdvOSS PCRF allows defining very advanced quotas through counter matching algorithms e.g. • Quotas for roaming only • Quotas for a specificaccess method like Wi-Fi • Quotas for a specific AAARealm

  21. Advanced Quotas

  22. Mid-Service Alerts A Service Provider can interrupt the service and push mid-service alerts from time to time. This may be for payment reminders, policy notices, advice of charge, advertisements or other reasons.

  23. Advanced Actions PCRF allows many advanced actions based on rules evaluation including: • Customized Notifications • Lawful Intercept • Different Regulatory requirements • Captive Portals • Network Provisioning

  24. Advanced Actions Captive Portal

  25. Advanced Actions Payment Notification

  26. Advanced Actions Package Upgrade

  27. Advanced Actions Bill shock Prevention

  28. Advanced Actions Advice Of Charge

  29. Advanced Actions Grace Period

  30. Other use cases Many more use cases can be realized over a PCRF solution. Some of them can be found at http://advoss.com/pcrf-business-usecases.html

  31. DPI Use Cases In conjunction with a DPI (Deep Packet Inspection) engine, AdvOSS PCRF offers control of individual application flows offering: • Flow Based Control • Application Based QoS Assurance

  32. Advanced QoS Management If the Enforcement layer supports more granular QoS control, then AdvOSS PCRF can be configured to control QoS parameters for the full pipe or individual flows. Main QoS parameters include: • Maximum Bit Rate (MBR) • Guaranteed Bit Rate (GBR) • Allocation Retention Policy (APR)

  33. Diameter Interface AdvOSS PCRF is fully diameter compliant and offer standard 3GPP interfaces for Diameter protocol including: • Gx • Rx • Ud (immediate roadmap) • Rx+ (roadmap)

  34. AdvOSS Service ControlHSS (Home Subscriber Server) • AdvOSS HSS is required by any communications service providers such as Telecoms, wired and wireless broadband providers in 3G, 4G, LTE or other technologies as the centralized data repository. It stores subscribers identities and subscription data about all subscribers and their service offerings. It is also required to keep track of service add-ons and their subscriptions by individual subscribers. It serves service profiles to Application servers or policy enforcement points.

  35. Service ControlProductsRoadmap Q2 2014: support for LTE Main Goal is to make products PCC Framework compliance which will automatically make AdvOSS Service Management Products LTE Compliant (Expected to be completed Q2 2014). AdvOSS is in process of implementing the following interfaces.

  36. AdvOSS SDP Software Architecture

  37. Platform Distributed Data processing • Data Replication-Central write & Distributed reads • Data partitioning with replication

  38. AdvOSS SolutionsKey technology BenefitsHigh Availability

  39. AdvOSS SolutionsKey Technology BenefitsScalability • AdvOSS uses the following technologies and architectures to achieve Scalability • Dispatcher/Server Model • Layers of Dispatching • Replication Dispatcher/Server Model

  40. AdvOSS SolutionScalability • AAA Server is composed of a front-end protocol dispatcher/load balancer that acts as a proxy for all NAS clients. • The Dispatcher load balances the traffic to AAA applications instances spread across multiple CPU cores • Each instance of Dispatcher is capable of handling up to 2000 AAA requests per second for RADIUS/DIAMETER protocol whereas a single instance of AAA Application running on one CPU core is capable of handling a minimum of 80 TPS.

  41. AdvOSS SolutionScalability: Upgrade path to 20K TPS and beyond Scalability to 20k TPS and beyond can be achieved by: • Adding additional Dispatchers running on new Hardware • Running AAA applications spread across multiple CPU cores behind additional dispatchers • Adding an additional layer of Dispatching as shown in the following slide

  42. Scalability: Upgrade path to 20K TPS and beyond • Layers of Dispatching: For large scale Operators extra layer of dispatching can be added

  43. AdvOSS SolutionsKey Technology BenefitsDatabase Scalability • Replication: AdvOSS database designs separate the OLTP Servers where all writing of new data is going on from the OLAP Servers where all heavy reads and analytical processing is going on. This provides almost limitless scalability as it is possible to put more and more servers all getting a copy of data in real-time where heavier processing can be done without effecting the master Transaction Processing Servers.

  44. AdvOSS SolutionsKey Technology BenefitsHeterogeneous Databases • Replication between Heterogeneous Databases: AdvOSS uses advanced database replication middleware to synchronize data between different types of databases e.g. from MySQL to Oracle in real-time.

  45. AdvOSS SolutionsKey Technology BenefitsRedundancy AdvOSS uses different technologies in combination to achieve redundancy in the system Storage Redundancy: All databases are redundant and use advanced multi-master replication techniques to keep up to date with each other. Computation Redundancy Database Multi-Master replication offers computation redundancy as well. Processing can be switched to secondary servers in real-time without loss of continuity. Switching and AAA All Switching and AAA architectures work on a dispatcher / Serving node architecture. Dispatcher does real-time load balancing among all Serving Nodes. If any Serving node goes down, processing carries on through other available nodes.

  46. AdvOSS SolutionsKey Technology BenefitsDisaster Recovery The System can be deployed in geographically distant data centers, for disaster recovery reasons. Using the DR setup, existing services realized through AdvOSS Solution deployed at main site can keep on working in the case of a disaster that makes primary solution unavailable for any reason.
