CONNECTING THE WORLD WITH APPLICATIONS
Two Key Components - Servers
 Proxy Server
 Heart of SIP network which contains all service logic
 Redirect Server
 Returns routing information to the initiating endpoint
 Registration
 Registration enables subscriber mobility

CONNECTING THE WORLD WITH APPLICATIONS
Where Should SIP Servers Reside?
 Service Provider Networks
 ITSP’s
 Long distance carriers
 Cable MSO’s
 Firewalls
 Network address translations
 Network Access Points


CONNECTING THE WORLD WITH APPLICATIONS
SIP Is Interoperable
 2 Successful Bake-offs
 15 companies
 Began with basic call set up (2 Vendors)
 Elevated testing to more advanced features such as; authenticated
registrations, multi-hop proxy and media transport
 Communication Between Endpoints
 Two vendor demo - PingTel
 Moving Forward with Interop Testing
 Bake-off needs to focus on three-way testing between vendors to better
model the needs of a commercial network

CONNECTING THE WORLD WITH APPLICATIONS
SIP is Scalable
 SIP Scales to the Internet
 HTTP server comparison
 Documented SIP Performance Exists
 Ability to scale to 500,000 BHCA
 Moving Forward with Scalability
 Develop performance benchmark
 Continued SIP performance from multiple vendors to eliminate any
speculation that SIP is ready for deployment NOW

CONNECTING THE WORLD WITH APPLICATIONS
SIP is Extendable
 SIP-T - SIP for Telephony Interworking
 SIP for intra-softswitch communications
 Allows for the bridging of the PSTN and IP networks
 CPL - Call Processing Language
 Network edge service creation
 Allows for the Proxy Server to handle service requests
 DCS - Distributed Call State
 SIP for cable telephony
 Allows for service intelligence to be decentralized
