Why are Communications ApplicationsConverging on Java Containers?

Telco apps moving to component based architectures

Desire to use Standard, Off-the-shelf container

Write-once, run-anywhere

Container provides important infrastructure services

Higher level abstractions for State management, Transactions, Security,Resource pooling,

Focus on core value-add application logic

Leverage large community of Java developers

Leverage enterprise development tools, test suites,

Time to market and reduced development cost

SIP ServletExecution Environment


SIP Servlet (JSR 116) SIP Servlets typically reside on network servers

make routing decisions

Supported RFCs:

RFC 3261, 3262, 3265, 3428, 2976

Utilizes http servlet model as foundation

builds on http generic part for SIP request and response functionality

Applications perform a complete set of SIP signalingactions

User agent client (UAC)

User agent server (UAS)

Proxy server


SIP Servlet Goals

Simplicity for the application developer Containers handle non-essential complexity

Containers support converged applications Applications that span multiple protocols and media types

Third party application development An XML DD is used to communicate application information from

the application developer to deployers

Application composition Several applications can execute on the same incoming or

outgoing request or response

Each application has its own set of rules and executesindependently


Extension to HTTP Servlet Model

HTTP is not a peer-to-peer protocol like SIPtherefore SIP Servlet extensions include:

Initiate requests

Receive responses as well as requests

Generate multiple Responses

one or more 1xx followed by a final response

Proxying requests, possibly to multiple destinations


Protocol and Application Sessions

SIP Servlet defines two types of sessions:

SipSession (Protocol Session)

Equivalent to HTTP Session and represents a Dialog in SIP

SipApplicationSession

Provides storage for application data

Enables different protocol sessions to share state i.e., HTTPand SIP

Defined by SIP Servlet but is expected to be adopted by theHTTP Servlet specification in a future release.

Session InitiationProtocol (SIP)


Java-standard interface to a SIP signaling stack

Standardizes the interface to the stack

Standardizes the events and event semantics

Application portability - verified via the TCK

Designed for the developer who requires powerful access tothe SIP protocol

JAIN SIP can be utilized in a user agent, proxy, or embeddedinto a service container

Supported RFCs:

RFC 3261, 2976, 3262, 3265

RFC 3311, 3428, 3515

Features provided by JAIN SIP

Provide methods to format and send SIP messages

Parse incoming messages

enables application to access fields via standardized interface

Invoke appropriate application handlers when protocolsignificant

message arrivals, Transaction time-outs

Provide Transaction support

manage Transaction state and lifetime on behalf of application

Provide Dialog support

manage Dialog state and lifetime on behalf of application


JAIN SIP & Instant Messaging

Suitable for IM and PresenceClients and Servers

Supports required methods andHeaders

Creates and manages Dialogs forSUBSCRIBE and MESSAGEmethods

JAIN IM Client SipListener is about1100 LOC

Interoperates with Microsoft IMand packaged with RI


JAIN SIP in Proxy Servers

Facilitates construction of ProxyServers

Stateless, Transaction-stateful, andDialog-stateful operation

Access to Dialog/Transaction stateand route tables

Extensibility and applicationcontrolled Routing

Deep copy semantics for cloning

Proxy (including presence server) isabout 3500 LOC and is includedwith RI


JAIN SIP Support in JAIN SLEE

JAIN SLEE represents network resources as resource adaptorsand each resource adaptor has a type

Resource adaptor type for JAIN SIP is javax.sip

JAIN SLEE identifies Event by Event types JAIN SIP Events are classified RequestEvents, ResponseEvents and

TimeoutEvents, each of these classifications contains numerous types

For example the event type of a Request message of type INVITE isjavax.sip.RequestEvent.Request.INVITE

JAIN SLEE represents the flow of events as activities

Activity Objects in JAIN SIP are ClientTransactions (locally initiated) andServerTransactions (remotely initiated)

Designed for the CLDC profile, however can be usedwith the CDC profile

Gives transactional control over the SIP protocol

Client devices must support SIP for Rel5.0 of the UMTSarchitecture.

SIP for J2ME is the perfect platform for these client devices

SIP for J2ME (JSR 180)


Enables terminals supporting CLDC to run SIP enabledMIDlets

Builds upon CLDC Generic Connection framework

Specifically targeted at mobile phone handsets

Retains the look and feel of the HTTP API

Ensures small API size and keeps the number of createdobjects low

Provides developers with helper functions

Sample vendor solutions


Telco-specific development will be facilitated by using off-the-shelf middleware platforms, along with component-centricsoftware platforms and architectures, such as J2EE and JAINSLEE. With this we can see a reduction in infrastructure costsand opportunities for new revenue-generating services.

Elmar Weber, Vodafone

Open network interface is the thrust of our whole NextGeneration Services environment. While we may choose to gowith a vendors proprietary API that meets an internal businessneed, JAIN will be the minimal entry requirement.
