1 2008 NAEO Annual Conference Matthew S. Crocker Computing power Networking power Prediction: Computers will get faster! Moore s law Computing power will double every 2 years
2 Virtualization CPU power is wasted, sitting idle, eating power Virtualization runs multiple virtual machines on the same hardware, increasing efficiency, Security & Reliability VMWare Citrix (XenServer) Microsoft Virtualization Server Prediction: Networks will get faster! All communications can be broken down into three types of networks Broadcast networks (radio, television) P=N Point to Point networks (PSTN) P=N^2 Point to multi-point Networks (Internet) P=2^N
3 Using the power of the Internet for all applications. Spend your money making your Internet connection fast and reliable. EoIP MPLS SaaS VoIP Everything over IP All applications will migrate to IP technologies Backup Disaster Recovery Business Continuity Credit card processing Paging Multi-Protocol Label Switching High performance network infrastructure able to provide QoS, Security, Survivability, Reliability Based on IP Technology All major national/global carriers operate MPLS networks. The Internet is a virtual network running over an MPLS core. Allows carriers to provide Differential Services to replace legacy applications (ATM, Frame Relay )
4 Software As A Service Web based technologyallows hosting providers to deliver desktop applications over the Internet Google NetSuite Salesforce.com Microsoft& Yahoo! Let the hosting company deal with backup, disaster recovery, development Voice is an application Voice over Internet Protocol NOT equal to Voice over the Internet VoIP is free of geographic limitations TNs can be anywhere QoS REQUIRED (avoid the Internet) Signalling SIP,MGCP, H.323 Codecs g.711u, g.729 TDM is dead is dying VoIP has massive growth potential SMS Texting & IM replacing voice
5 SIP Interface for Infinity VoIP enabled voice-logger Switching operator stations to VoIP Softphonew/USB headset Replacing PRIs with VoIP SPAM Unreliable Insecure Convert to web based services for message pickup & delivery (IS) using SSL Confirmed message pickup Makes customers sticky Hosted messaging new business opportunity (SaaS) Bandwidth, bandwidth, bandwidth QoS is required but does not create bandwidth High speed, low latency, LOW JITTER!!!! N+1 for IP connectivity Symmetrical service (no DSL) 80kbps per g.711u call 20kbps per g.729a call
6 Teenagers text more than they talk They will be our customers customer in the next 5-10 years How will you handle the communications needs of your customers in the future? SMS -> Message that can be acted on Instant Messaging We have an opportunity to provide additional communications services for our customers. Makes our customers Sticky Low Capex, outsource to hosting providers We become the aggregator, wholesaler, integrator of our customers communications needs. Questions?
7 Quality of Service It is all about QoS DSCP aka DiffServ. The Internet doesn t support QoS MPLS does support QoS QoS is an end-to-end solution, all devices must support QoS in order for it to work. Latency (how long does it take) Jitter (How often does Latency change?) High Latency is ok, high Jitter is BAD! Differentiated Services Code Point Part of an IP packet header (Express mail) Packets are marked with DSCP at the end points DSCP is checked at every router/switch in the path Routers/Switches use DSCP to select queues for packet processing. Express lane for high priority traffic QoS needs to be configured on EVERY device in the path, it is NOT on by default G.711u same 64kbps as TDM but packetized. High quality, high bandwidth codec 80kbps per call G.729 compressed, low bandwidth, high CPU requirements, licensing fees 20kbps per call T.38 Faxing over IP
8 Session Initiation Protocol (SIP) SIP has won the battle. MGCP, Megaco, SCCP (skinny), H.323, H.248 Signaling is what does call setup and teardown Similar to ISDN-PRI (q.931) Asterisk is an open source VoIP PBX/switch/Voic /IVR application Runs on Linux
