1 FSFS Conference: Dec 9-11, Thiruvananthapuram Project SailFin: Building and Hosting Your Own Communication Server. Binod PG Senior Staff Engineer Sun Microsystems, Inc. 1

2 Agenda SailFin: Open Source Java EE meets Telco Building Your Own Communication Server Hosting Your Communication Server SailFin: Clustering. SailFin: RoadMap. 2

3 The Future is Not What it Used to be... Handsets & Consumer Electronics Voice & Data Services Fixed & Mobile Carrier? Interpersonal Communications Media & Network Increased Subscriber Choice/New Competitive Threats/Increased Market Complexity 3

4 Imperatives for the Carrier Focus on value creation and monetization Create new control point by becoming the destination for subscribers How? > Service Oriented Architecture allowing content providers to also participate and benefit > Find technology that is not tied to any one particular standard and is flexible > Move to standards technologies for vendor choice, lowered costs and best-of-breed solutions 4

5 TM Java Platform for Telcos JavaTM ME shipped on 1.8 billion devices so far JavaTM Virtual Machine is extremely robust and scalable and is widely deployed in enterprise and telecom core infrastructure JavaTM EE is now entering Telco in a big way > JSR-289 creates Java EE + SIP Servlets portability > Database Access, Web Services, XML Processing, Resource Adapters, Messaging, REST,.NET interoperability, Transactions, Security etc. are now naturally available to Service Developers 5

6 TM Java EE 6 Java EE 5 has been the most successful platform to date with highest velocity of adoption Java EE 6 is about further developer productivity and platform simplification > > > > > > Creation of profiles, web profile for a start Introduction of WebBeans (based on SEAM) Java Persistence API 2.0 Servlets 3.0 (comet, annotations) REST Web Services Updates to EJB, Connectors 6

7 SailFin: Open Source Java EE Meets Telco Started with Ericsson contribution of code and resources Launched May '07 at JavaOne Part of GlassFish community on java.net GPLv2 and CDDL licenses Basis for Sun commercial product: Sun GlassFish Communications Server 7

8 SailFin: Building Your Own Communication Server 8

9 Can you do this in Java EE? 9

10 SIP Technology makes it possible Session Initiation Protocol > Defined by RFCs 3261(sip), 4566(rtp), 3550(rtp) > Only responsible to set up communication Similar to HTTP > Text Based Request and Response > Shared status codes (200 OK, 404 Not Found) > Associated SIPSession Different from HTTP > Peer To Peer > Asynchronous 10

11 An Example 11

12 SIP Servlets Handle SIP message processing > Based on Generic Servlet model > SIP Applications, Sessions and Timers Defined by JSR-289 > Converged Web and SIP applications. > Http and Sip Sessions can access each other. > Http Servlets can initiate calls SIP Application Servers > Stand-alone (pure SIP) > Integrated SIP and Java EE Application Servers 12

13 SIP Servlet Example Code. 13

14 Converged HttpServlet Example. 14

15 Tools NetBeans 6 Plugin > JSR 289 EE 5 support > Deploy and debug pure and converged Applications > Wizard based SIP Application authoring > SIP Testing Client Ericsson SDS > E2E Service Development and Network Element simulation 15

16 Application Router Java EE SailFin AS SIP Application 1 CHARGING Initial SIP Invite PRIVACY SIP Application 2 LEGAL IC BARRING Application Router CALL WAITING LOCATION Invite External SIP JSR 289 Container 16

17 What Do You Get with SailFin? All of GlassFish > Fresh Java EE standards compatibility > Project Metro: Web Services Interoperability > Open ESB: Service composition capabilities > Complete Administration w/ GUI and CLI > High Availability Leading Performance & Quality > Measured with SPECjAppServer JOPS (1 chip, 8 cores, 32 HW threads) JOPS (6 chips, 48 cores, 192 HW threads) Plus, deployment quality JSR-289 container 17

18 Need More? Update Center 18

19 Samples and Demos Source included in SailFin > CallSetUp B2B User Agent > Online Bank Other Applications > VoiceBridge: All Java RTP Stack and Voice Mixing JSR-309 compatibility in future > Sun Labs Conference Manager (TBD) > Sample Presence Server (TBD) > STUN Server (TBD) 19

20 SailFin: Deploying/Hosting Your Communication Application 20

21 Host VOIP Server at Your Home? Install SailFin (Free and Open Source). Deploy Your Sip Servlet Application. Configure Your Home Router. > Open HTTP and SIP Ports Contact Address of the Server (SailFin). > Permanent IP. > Dynamic Host Name (dyndns etc). Your VOIP Server is Ready! > Anyone can use it from SIP SW Phone or SIP HW Phone. > Remotely Administer the Server. 21

22 Ease of Use - Administration 22

23 Challenges. NAT Translation > STUN Firewall. > No problem if you are at home. > Corporates need to allow VOIP. > VOIP enabled Firewall. SIP Security. 23

24 Security Confidentiality and Integrity of SIP messages using TLS User Authentication > Sip Digest Authentication Algorithm : MD5 Realms supported by default : JDBC > P-Asserted-Identity Authorization > Based on Java EE roles,group and principal mapping. > Uses JACC (Java Authorization Contract for Containers) Configuration to define trust domains eg: trusted sip entities(hostname,ipaddress) 24

29 Project SailFin Architecture High availability: Converged Load Balancer A Project SailFin cluster is typically fronted by a HW load balancer The HW load balancer routes the traffic to any random Project SailFin instance Traffic from SIP User Agent and HTTP browser might reach any instance The converged LB proxy in each instance then does a consistent hashing on the configured headers (eg: Conference ID) of the messages Thus traffic for a particular application instance (a particular conference) always reach the same instance 2008 JavaOneSM Conference java.sun.com/javaone 29

31 Session State Replication & Recovery SIP Application Session is key > Can contain multiple protocol sessions (SIP or HTTP) > Represents a converged application instance > JSR-289 formalizes ConvergedHttpSession Link to parent SIP Application Session Network of Session objects, associated Timers and Dialogs must be preserved for recoverability > Remoting has high overheads Converged Load Balancer maintains co-location of sessions inside a SIP Application Session > Each instance contains a self-load balancing proxy. > Routes the requests to appropriate instance. > Based on Consistent Hashing of Message Header contents. 31
