  • This slide is intended to highlight what our customers’ customer want out of the network. In the end of the day, consumers tend to get what they want
  • For the media industry bursting traffic is normal 10x burst is a small event gives “no” warning
  • Current traffic planning assumes only a fraction of users are active at any point time using a small percentage of access bandwidth Peak hour video changes this dynamic This model works well for BE service delivery and non-guaranteed user experience, but it breaks as soon as BASP and RSP want to guarantee service delivery with a defined SLA
  • Bandwidth is infinite Application gets full use of bandwidth and experience will be perfect Synchronization + collaboration are unnecessary Experience for the application is assured via transaction Making a request of the network is possible Network delivers a micro-SLA for each flow requested by applications Network performance is poor Put a hard drive at the user location as network is unreliable Experience is assured locally as network is not part of delivering experience (just transport to local
  • Strong partitioning… Mobile services very distinct from fixed services; infrastructure isn’t shared; most services (e.g. voice, mobility –or lack of-) are strongly access-dependent. PSTN/PLMN legacy. Overall lack of services. Multiple IP backbones
  • Customer has to independently sign up for fixed services and mobile services; end devices are dedicated per service type. Severe scaling & QoS issues (cf. tunneling + complex serialization of devices). PDIF interworking architecture is the most streamlined, yet still challenging.
  • IP Edges (SDF) may be Access-Optimized (e.g. scaling, signaling, legacy interfaces, etc), but play symmetric roles in Service Delivery, allowing cross-domain mobility . Then control planes and application servers are converged as well. Customer signs up for a single set of “Personal Broadband, IP untethered” services.
  • This is a three level network architecture similar to other NGNs such as IMS and FMC. At the services layers, we provide a number of open interfaces including SOAP and DIAMTER to integrate with third party solutions. We also have a few applications available that Tom will discuss further. Juniper has been leading the policy and control market for over 7 years with the introduction of the SDX-300 in 1999 and our acquisition of Funk Software and the Steel Belted Radius AAA server 100 customers globally are currently using the SDX, including the world’s largest IPTV deployment, PCCW SBR also provides industry leading, technology independent AAA solutions and has had much success with operators and is currently being used in 7 of the top 12 mobile networks Juniper’s OSCP program hits squarely on the focus point for the merger of applications and networks into a single service experience. In the packet handling layer, Juniper provides leading technology for both routing and security. Juniper products are known in the industry for their performance, quality of service, security and high availability for high quality delivery of all applications Our focus today is primarily on the policy and control layer where we have already had high success including: the industries only end-to-end deep policy management system that controls all segments of the network – the data center, the core, the edge, the access all the way into CPE devices tight integration with Junipers routing and security products acts as a perfect extension of the network infrastructure Support of standards with open interfaces and Juniper’s ecosystem of partners. We currently have over 20 partners leveraging SDX interfaces to applications or other network elements. This provides operators with flexibility to choose best of breed products and leverage standards-based interfaces to interoperate with the Juniper policy and control system.
  • NICK
  • Next-Generation Network OPEX Checklist -- Less (or no) aggregation -- More routing and optical integration in core -- More use of Ethernet -- Add security for infrastructure protection
  • Good and bad
  • Next-Generation National Infrastructure Checklist -- 99.9999% -- High availability, real in-service software upgrades -- Security protection for control path -- Service protection in emergencies
  • -high level depiction of the role of the SRC within the FMC architecture. -The SRC acts as the Resource Admission Control Function. -It uses the DIAMETER gateway interface to interact with other IMS elements such as the SPDF. -The SRCs main functions in this role are admission control and network policy definition. -This function ensures IMS or FMC applications can be support adequately by the packet handling network. -The SRC leveraged COPS-PR southbound to the E-series for access policy enforcement The main functions of A-RACF are: Admission Control (AC): The A-RACF receives requests for QoS resources from the SPDF via the Rq reference point, indicating the desired QoS characteristics (e.g. bandwidth). The A-RACF shall use the QoS information received from the SPDF to perform admission control, i.e. the A-RACF checks whether the requested QoS resources can be made available for the involved access. The A-RACF shall indicate to the SPDF whether a request for resources is granted or not via the Rq reference point. Network Policy Assembly (NPA): Access Network Policies are a set of rules that specify what network policies should be applied to a particular access line. The A-RACF ensures that a request from the SPDF (of a particular network service provider) matches the access policies, as multiple SPDF can request resources from the A-RACF. As the Rq reference point may be an inter-domain reference point, the A-RACF shall authenticate the SPDF requesting resources via Rq. The A-RACF checks if the request matches the requestor's (operator SPDF) profile. Only validated requests for authenticated requesters shall be retained as input. The A-RACF combines the requests from the SPDFs that have requested resources and ensures that the total of the requests match the capabilities of the particular access line.
