1.  Introduction
1.1 Project/Component Working Name:
    SER removal 

1.2 Name of Document Author/Supplier:
    Author: Lukas Rovensky

1.3 Date of This Document:
    19 March, 2010

1.4 The requested release taxonomy:
    Patch binding for the announcement and marking as Obsolete.
    Minor binding for the removal. 

1.5 Introduction

    This FastTrack will EOF the Sip Express Router (SER) and its web based
    interface -- SERWeb -- from Solaris Next and obsolete SER and SERWeb in 
    Solaris 10.

    On November 4th 2008 a new SIP Router project was announced and joined
    by SER developers, [1].  This also means that SER itself is no longer 
    developed in favour of the SIP Router, [2].  

    Since SER is no longer developed product it shall be removed from
    Solaris Next.  Should a similar product be required then the SIP Router
    (Kamailio) may be a good candidate.

    Note, that attributes(5) documents an exception, which can apply to this
    case:

         4.   An interface specification which  isn't  controlled
              by  Sun  has been changed incompatibly and the vast
              majority of interface consumers  expect  the  newer
              interface.

1.6 Previous Relevant ARC cases

    LSARC/2004/324 - sfw/SIP Proxy Server (actually still in waiting state), [3]

1.7 SIP Status In Solaris, RFC 3261 

    SER itself provides functionality, which implements SIP protocol, RFC 3261,
    [8].  There are currently also two libraries in Solaris, which implement 
    the SIP protocol (RFC 3261, [8]) and can be eventually used for 
    implementation of SIP routing:

       * libsip (also in S10, since U4), PSARC 2006/402, [4], CR 6461142, [5]
         This library is developed by Oracle and it is available both in Solaris
         10 and OpenSolaris / Solaris Next.  As per the responsible engineer,
         there is at least one customer, who had built its application using 
         libsip. 

       * libosip2, LSARC 2009/277, [6], CR 6826484, [7]
         This is an open source library, [9].  There are no further plans with
         this library as per the responsible engineer.

1.8 Input From Marketing, Usage of SER

    Marketing was informed about the intention to remove SER from Solaris
    Next.  They do not seem to have any real data, which would support or
    deny this action.  Their current position is as the following: 

    "Right now, I agree with the general position that SER seems like an
     unsupported offering and we should drop it, however we do need to
     assess if we should and who should pick up SIP router."

    The I-team also tried to approach OS Ambassadors (sig.oe@sun.com) to get
    more info about SER usage but no one provided any data. 

    The I-team also looked at IPS download statistics maintained by Stephen
    Hahn and by end of February 2010 SER reached 24813 downloads as part
    of OpenSolaris.

2.  Documentation

    Obsoleting SER and SERWeb in Solaris 10 will be announced in release notes
    for Solaris 10.  

    Interface Stability in SER man page (ser(8)) in Solaris 10 will be set to 
    "Obsolete, External".

3.  Packaging and Delivery

    SUNWserr, SUNWseru and SUNWserweb packages will be removed from
    OpenSolaris.  This does mean that the renamed packages will no longer
    be delivered (service:network:sip:ser and
    service:network:sip:ser:administration).

4.  Interfaces

    All the interfaces described below will be obsoleted in Solaris 10
    and removed from OpenSolars / SNV.

    The following files and directories (including all their content) will be
    removed from OpenSolaris / SNV:
   
    /usr/sfw/sbin/ser
    /usr/sfw/sbin/serctl
    /usr/sfw/lib/ser/ 
    /usr/sfw/share/doc/ser/
    /etc/sfw/ser/
    /usr/sfw/share/serweb/
