Re: SS7

[Douglas Otis]

Jim,

Telco has a goal of maintaining 5 9's where SCTP was developed to  
carry their SS7 protocol.  The FreeBSD stack for SCTP supports IPv4,  
IPv6 and multi-homing.  This protocol immediately recovers from  
network path failures as it heartbeats against alternative paths.  The  
protocol can sustain a large number of connections over extended  
periods, takes less time for connection setup than TCP, and overall  
latency can be less than UDP while still supporting partial reliability.


SCTP has improved error detection suitable for jumbo frames.  In  
addition, the error checking algorithm is now an instruction in i7  
core Intel processors and is found in many NICs.  The SCTP connection  
setup returns a cookie to minimize resource exhaustion concerns, to  
guard against source address spoofing, connection hijacking, and DDoS  
attacks.

Dear Sir or Madam,

Is there a working group on converging legacy protocol stacks and  
mapping
legacy stacks addressing mechanisms into IPv6 addressing? For  
example, RFC
4291 & 4038 specifies that :::x.y.z.w represents IPv4 node  
x.y.z.w -
is there a similar draft concept for specifying a Message Transfer  
Part

point code for an SS7 stack or other telephony protocol network layer
mechanisms into IPv6 addresses?

Thanks much,

RE: lateral approach to SS7/VoIP over satellite

[Yaakov Stein]

Dear Rubin

The only US patent I see granted to WTL is 6958999 from 2005.

If the subject of your IPR is the aggregation of multiple VoIP payloads
into a single packet in order to reduce overhead,
various methods to do this have already standardized in RFC 4170,
RFC 5087 section 5.2, and ITU-T Y.1452,
and have been widely deployed for the last 10 years.

Can you explain what is new or give a pointer to the application publication 
number ?

Subject: lateral approach to SS7/VoIP over satellite

Dear members,

I was inspired to submit content in order to explore the potential for 
integration of NOP into current revised standards for transmission of SS7 over 
IP over satellite.

If this content is deemed too commercial for this readership kindly advise or 
direct me towards a more appropriate audience; a brief overview of the concept 
is included in the text below related to a joint development successfully 
completed with ESA (European Space Agency): The complete article is covered in 
the attached link, and a separate .xls file includes calculation parameters for 
NOP benefits over SIP and H323.

"WTL has an excellent track record in providing equipment for voice services 
using satellite trunking and has over 100 systems deployed around the world. 
The company's key strength in this area has always been the superior 
bandwidth-saving capability of WTL's patented NOP (Network Optimisation 
Protocol).
The Artes 4 contract provided joint funding for a series of developments 
designed to make WTL equipment perform an even better job for telecom operators 
wishing to use these emerging low cost satellite services. One aspect of the 
ESA project was to modify NOP to operate efficiently over DVB-RCS services. The 
lower price point of DVB-RCS equipment and space segment means that this is of 
great interest to operators, particularly in the developing world."

Regards,



Rubin Rose

RE: lateral approach to SS7/VoIP over satellite

[Dan Wing]

For the RTP media, your PON is a tunnel, and there needs to be a way to bring
up the tunnel and do some VJ-like compression of the IP/UDP/RTP headers.  You
should look at ROHC <http://tools.ietf.org/wg/rohc>, ECRTP (RFC3545), and
TCRTP (RFC4170) to see what has been proposed in this area to date.

For SS7, I agree with Michael:  look at SCTP.

Further PDFs or other communications claiming to be mail from
this address won't reach my inbox.  The sender may also wish
to inform the list owner about their interpretation of "Note
Well"; see  and RFC 3005.

This was an error, I've deleted the material from my computer.

Hi Rubin,

Can you provide the documents in a readable format? Did you look at
SIGTRAN protocols?

You might want to send an e-mail also to the SIGTRAN mailing list...

Best regards
Michael
