10. 10 www.ellacoya.com Ellacoya Cost Savings ROI Components Reduced Circuit Costs Reduced Plant Costs Reduced RAN Costs Reduced Cust. Service Costs

11. 11 www.ellacoya.com Circuit Costs Management of P2P traffic has a substantial impact on backbone bandwidth Reduce upstream utilization by up to 50% without generating a single subscriber complaint Defer expensive circuit upgrades Before Ellacoya: 700 Mbps After Ellacoya: 450 Mbps

12. 12 www.ellacoya.com Plant Costs Congestion can be as expensive as circuit congestion Aggregate P2P management cannot solve this problem Per-IP management of upstream P2P reduces congestion Defer and reduce plant upgrade expenses including:  Splitting / de-combining nodes  Adding DWDM Before Ellacoya: 8 Mbps After Ellacoya: 5 Mbps

13. 13 www.ellacoya.com RAN Costs Congestion causes increased CPU utilization on routers Capacity Management addresses congestion in RAN Defer and Reduce expenses including:  Router CPU, Memory upgrades  Line cards  Forklift router upgrades Before Ellacoya: 75% CPU After Ellacoya: 64% CPU

14. 14 www.ellacoya.com Customer Support Costs Congestion impacts subscribers’ experience  Increases in Customer Support call costs  Increased churn Ellacoya management has a dramatic effect on volume of complaints about slow web browsing Reduce OPEX, reduce churn, increase subscriber satisfaction Time (10 minute interval samples) KBPs With Ellacoya: 500 Kbps Without Ellacoya: < 250 Kbps

17. 17 www.ellacoya.com Dynamic Rate Limits Allows subscribers to burst their traffic when the network is uncongested No rate limits when network traffic is light: ( e.g.) 300Mbps threshold Total traffic on GE link less than threshold Enforce Rate Limits when network gets congested: Total Upstream P2P RATE LIMITED to (e.g.) 20Mbps ( e.g.) 300Mbps threshold Total traffic on GE link greater than threshold P2P Rate limit (e.g.) 20Mbps is not Enforced P2P Other Traffic P2P Other Traffic

18. 18 www.ellacoya.com Offer-Level Rate Limits Individual Subscriber Application  Rate limit applied to the subscriber’s TOTAL traffic  Similar to global limit on DSL modem or cable modem  Can prioritize traffic within the overall rate  Can exclude certain traffic types from the restriction HTTP P2P Video NNTP Game IM VoIP 512 kbps 384 kbps 256 kbps 384 kbps 128 kbps 256 kbps Standard Rate Limits (rate limit per application) Total Traffic Limit (e.g. 2Mpbs) Total Traffic 2.4Mbps

20. 20 www.ellacoya.com PacketCable Multimedia (PCMM) Industry standard for policy-based application QoS Introduces application manager and policy server components Requires application and subscriber awareness (1) Service Request (2) Policy Request Application Manager CMCMTS HFCIP PC Policy Server CM CMTS HFCIP Application Server (3) Policy Set (4) DOCSIS Service Flow Messaging Application Activity Content Provider Note: Recordkeeping Server omitted from diagram

21. 21 www.ellacoya.com Classic PCMM Model One AM to integrate per content/application source  Security/authentication/encryption Application manager is usually server hosted  Subscriber authentication under ASP control Does not work with peer to peer applications, for example:  Gaming consoles  PC games  Some forms of VoIP  Video conferencing  Home surveillance  … and many more

22. 22 www.ellacoya.com Distributed Application Manager Ellacoya Multimedia Service Manager (MSM)  Distributed deep packet inspection AM –In each switch, with the capability to recognize all applications  Leverages subscriber and application awareness  Activates QoS for subs part of specific service tiers MSO benefits of MSM  No need to integrate third party AMs into the PCMM network  Puts AM function under MSO’s control –MSO owns direct subscriber relationship  Works with all applications: server-based and peer to peer

23. 23 www.ellacoya.com Automating PCMM for any Application Modem PS Internet CMTS Application Server Application Activity Content Provider Or Peer Node Subscriber uses application QoS Policy Request Policy Set DOCSIS Service Flow Messaging MTA Multimedia Service Manager (MSM) on switch functions as distributed Application Manager by using “signature detection” for any application, signals to Policy Server Policy Server signals to CMTS Applications get PCMM QoS without Application Manager development Ellacoya Software Ellacoya Switch SIP-based Phone OSS Subscriber Details RKS Usage Records MSM

24. 24 www.ellacoya.com Allows Operators to increase revenue immediately  Simplifies the roll-out of PCMM-based applications  Removes the need for cable-specific AMs for each application  Works with any application Puts authentication and authorization back in the Operator’s hands  No third party AM integration required  Entire PCMM infrastructure is owned and operated by the Operator  Helps MSO further build direct relationship with the subscribers Based on proven \ technology  Deployed in cable networks worldwide since 2002 Benefits of Distributed PCMM Solution
