11 ©2005 BEA Systems, Inc. | 10 In the Beginning: call setup done manually 1.Hi Betty. Can you connect me to Earl over in Wichita? 2.Hi Sue. I have a call for Earl. Can you see if hes available? 3.Sure. Im ringing him now. 4.Hello? 5.I have Earl on the line 6.Go ahead

12 ©2005 BEA Systems, Inc. | 11 Prior to the mid-1960s the service logic was hard-wired in switches Prior to the mid-1970s signaling and media (voice only) traffic were carried over the same channel via Pulse Code Modulation. Slow service creation and deployment 24+ months Inefficient use of network resources Limitations on the types of messages and services that could be supported S1 Logic S1 Data S2 Logic S2 Data S1 Logic S1 Data S2 Logic S2 Data PCM Before Digital Switching

13 ©2005 BEA Systems, Inc. | 12 Moving Signaling Out of Band Stored Program Control (SPC) switching now service logic was programmable Simplified the introduction of new service logic but still in months timeframe Mid-1970s introduction of Common Channel Signaling Signaling was now sent over a separate network More efficient use of network resources More varied messages and services Signaling Transfer Points (STP) Signaling Network SS7 S1 Logic S1 Data S2 Logic S2 Data S1 Logic S1 Data S2 Logic S2 Data PCM SS7 SIP H.323

14 ©2005 BEA Systems, Inc. | 13 Evolution of digital voice network (H.323) H.323 (one of the two major standards for VoIP) It was first released in 1995 by ITU-T The majority of existing IP telephony products rely on the H.323 because of its early existence Characteristics: vertical approach (from codec to signaling), binary format, longer session setup time SS7 SIP H.323

15 ©2005 BEA Systems, Inc. | 14 Evolution of digital voice network (SIP) SIP becomes the mainstream standard for developing next- generation VoIP-based applications and services. It was first approved in 1998 by IETF. Characteristics: horizontal, text-based protocol, scalable (lightweight user agents), simplified signaling scheme makes it faster SIP is industry-endorsed. More and more SIP-based products are and will be available in the market versus a slow adoption of H.323 standard. This makes SIP the most popular standard for VoIP solutions. SS7 SIP H.323 SIP has been designed from scratch to scale and to remain simple

16 ©2005 BEA Systems, Inc. | 15 SIP prevails over H.323 in VoIP SIPH.323Implications Use in 3GPPYesNoMany expect H.323 to disappear with deployment of 3GPP networks ExtensibilityThe protocol is open to new protocol features (Text-based protocol) Vendor specific 'nonstandard Param' at predefined positions only (Binary-based protocol) Debugging binary extensions difficult since they are unknown to protocol analyzers and unreadable to humans ArchitectureModularMonolithicMonolithic design makes component updates difficult and expensive Transport protocol UDP and TCP, most implementations use UDP UDP and TCP, most implementations use TCP Usage of TCP results in higher call set-up time Instant Messaging Support YesNo

17 ©2005 BEA Systems, Inc. | 16 What is IP Telephony? Instead of using traditional circuit switch systems for voice communications, IP Telephony uses a packet protocol originally designed for data communications. Circuit Switched - PSTN Packet Switched – Data Network

18 ©2005 BEA Systems, Inc. | 17 IP Based Networks IP as the transport protocol for both media and signaling Media: Packetized voice instead of TDM virtual circuits Signaling: internet protocols (incl. SIP) instead of SS7 and proprietary PBX protocols Programmable servers, open APIs, third-party services instead of closed switches and PBXs LindaPeter lts.ncsc.mil bea.com Proxy DNS Location server Media Streams INVITE Ringing 200 OK ACK INVITE

19 ©2005 BEA Systems, Inc. | 18 VoIP Services with Gateways to the existing circuit-switched PSTN Examples SIPphone, SkypeOut But, Voice over IP is not the same as Voice over Internet similar technology and standards, but different medium the challenge is level of network quality control

73 ©2005 BEA Systems, Inc. | 72 BEA WebLogic Network Gatekeeper Primary purpose is to protect network resources in the presence of 3rd party applications Need exists to monitor and manage 3rd party access to network Allows for management of 3rd party services and providers Support policy definition and SLA enforcement Interaction with policy engine is transparent to developer and end-user of application Non-technical telco staff able to define application policy Must be protocol agnostic Standards compliant where applicable (e.g., WS-Security, WS-Policy) Provide 3 rd party (and internal) developers with consistent interfaces to network capabilities Single point of management for partner access, with high degree of control over access rights and enforcement actions Faster time to market for internal and 3 rd party developed applications Reduce cost of partner and application management by automating key processes
