4 Centralized Business Routing, Policy and Control The Missing Link to Introducing Value Added Services Mark Muchow RVP, Sales

5 Centralized Business Routing, Policy and Control Centralized Routing /Policy Control across a carrier s entire network is the missing link to increase revenue and lower cost. Leveraging legacy and NGN investments requires automation/flexibility to draw external data into the real time call path to provide differentiated services. Ability to leverage business policies derived from Fraud, QoS, Margin Assurance, Subscriber Profile, Presence and Location key to customer retention, revenue and cost savings.

8 IP Assurance Service Provider Networks Raymond Chiu Local Backhaul Networks March 22,

9 Delivery of Enterprise IP Telephony Delivery of mission critical applications including Enterprise IP Telephony places a significant obligation for meeting SLA delivery of end-to-end transport over multi-service Provider Network(s) In many cases, the complete transport network is comprised of one or more Service Providers Incumbent Carriers Competitive Providers Cable MSO s COMPTEL PLUS March 22,

10 Challenges for Service Providers Transport Technology Progression Traditional TDM to IP-packet infrastructures Integration of architectures Hybrid network architectures Multi-Provider Integration On-Net and Off-Net (type 2) transport circuits Class of Service mapping SLA delivery: variation vs. conformance Cloud-based (hosted) services IP SLA Assurance of multi-network architectures COMPTEL PLUS March 22,

11 Multi Service Provider Networks End-to-End SLA Assurance from UNI to UNI through entire network transport path ENNI CoS Mapping and Interoperability Challenges of SLA Monitoring and Reporting Multi-provider Multi-vendor Multi-technology COMPTEL PLUS March 22,

12 IP SLA Assurance The ability to provide consistent SLAs throughout the network is the key, as well as a competitive differentiator. Vertical Systems Group 03/2011 Delivery of Enterprise IP Telephony and other performance sensitive applications require the enhanced capabilities of Carrier Ethernet The on-going advancements of Ethernet OAM standards offer the framework and capabilities to offer IP Assurance performance measurements & metrics Quality of Experience necessitates t a capability (tools) to leverage OAM for monitoring & reporting on IP Assurance measurements. COMPTEL PLUS March 22,

13 How to leverage OAM capabilities? Carriers must have tools designed for Carrier Ethernet that encompass: 1. True End dto End dip Circuit it Performance and Network Nt kvisibilityibilit Performance thru Multi vendor/technology transport networks. Visibility thru multi carrier/service providers networks (off net). 2. SLA Assurance Reporting Real time & Predictive SLA performance monitoring SLA conformance and auditing reporting Internal & Customer facing 3. Network Resolution Intelligence Isolation of problem and source across entire network Supports troubleshooting through multi everything infrastructures OcularIP provide real time holistic analysis with network visibility of IP based circuits performance; enabling Application dl delivery over multi technology, l multi vendor, & multi carrier networks. COMPTEL PLUS March 22, 2011

14 About Local Backhaul Networks Local Backhaul Networks is a Network Integration and Application Delivery organization. OcularIP is a Circuit & Performance software application for IP Assurance of multi-technology, multi-vendor, and multiprotocol transport networks.

15 Deploying SIP Services to Enterprise Jesse Lee Senior Solutions Manager

16 The Customer Premise Encompasses everything from the WAN connection to the phone. Most likely target for mix of owned and BYO Copyright Metaswitch Networks Proprietary and Confidential 16

17 The Customer Premise Deployment Model Scalability Complex set of moving parts Must be repeatable at every customer Reliability Some aspects out of your control Supportability Remote access and diagnostic reach

18 The Customer Premise Equipment Using existing equipment Will require time consuming network analysis You may not have access to diagnostics Someone else controls configuration Data networks are MUCH more tolerant to latency and other issues than Voice communications

19 The Customer Premise Equipment If you use your own equipment & infrastructure You can prequalify the hardware you deploy No need to do this for every customer Results are predictable You can set proper QoS You can monitor the network to the desktop Latest & Greatest Winner!

20 The Customer Premise Avoid unmanaged exceptions If an exception must be accommodated Acknowledge it is an exception Set expectations appropriately Understand it and mitigate risks Productize it so it is a managed exception The Nth exception may already be (nearly) accommodated

21 Premise router Terminates the WAN connection Provides NAT and QoS Provides diagnostic reach

22 Premise router Scalability Ability to deliver WAN termination Consistent firmware and models Consistent configuration across 100s of sites Diagnostics Quality of Service (QoS) Configuration control Reliability Must perform NAT reliably Reboots must not be part of normal operation! Supportability Administration access to router and beyond Bandwidth and availability monitoring i

23 Premise ethernet Key target for control and diagnostic reach Provides separation of data and voice traffic

24 Premise ethernet What can you get from the ethernet switch? Power-over-Ethernet over VLANs and QoS for voice/data separation Diagnostics Port mirroring Logs Statistics

25 Phone Part of the desktop experience THE demarcation for your service

26 Phone Criteria SIP Provisioning Server Interoperability Deployability XML application support User experience Capability to deliver your defined service! End user expectation/familiarity Expertise in your organization Existing hardware Vendor relationship Price Only choose interop tested models
