RE: [ebxml-dev] ebXML and limited resources - MSH implementations

[BELFORD Neil <Neil.Belford@vencorp.vic.gov.au>]

Hello Steve,

No we did not write our own MSH, our industry hub is an implementation of webMethods using their ebXML package, as is the VENCorp gateway. The various participants use gateways provided by different vendors, none of them wrote a MSH from scratch.

This really demonstates the strength of the specification - even without a valid schema for ebMS v1.0 - which several of you may remember me howling about some months ago. However this would not have been possible without a strong overarching specification explicitly defining how we as an idustry would deploy the ebXML solution.

Niel,

Just curious, did you write your own ebXML MSH or did you use one from a
commercial provider?  If commercial then who did you use?

I would imagine that most of the utilities you have integrated had
existing middleware.  In that case you would have needed to embed ebXML
MSH capability into a variety of different platforms.  That is a task I
need to do and have found myself having to write (more acccurately, ask
a programmer to write) an ebXML MSH that I can deploy in Webmethods,
WebSphere, etc middeware solutions.

Regards,

Hello Daniel,

We have just gone live with an industry wide B2B implementation using
the ebXML messaging infrastructure, carrying an aseXML document as the
payload. aseXML is the Australian energy industries data description
language.

I'm not sure what you mean by network resources, if you want high speed
network performance, clearly - dont use any form of web services, ebXML
or otherwise, don't use anything that uses HTTP as the transport layer.
If you are in an all Java environment use RMI (in conjunction with
RMIProxy http://www.rmiproxy.com/ if you have to cross firewalls -
otherwise it will fall back to HTTP anyway and defeat the purpose of the
technology). If you dont have the option of deploying on RMI then you
need CORBA and middleware. The difficulties of CORBA (and DCOM for that
matter) is kind of the problem that cumbersome web services are there to
fix. So - if ubiquity demands you sit on HTTP (or SMTP for that matter)
using an intermediate data description language (presumably some flavour
of XML) - expect overheads in the gateways and on the network.

ebXML is an excellent solution to many of the problems posed by inter
enterprise collaboration, certainly here in the Gas industry it has been
a startling success in the form in which we have used it ( ebMS v1.0
with signing and reliable messaging). However while it offers excellent
abstraction from the disparate platforms that are deployed by the
various participants, it is by no means 'lightweight' in the gateways.
The overheads in HTTPS, digital signing, reliable messaging, and so on,
are substantial, particularly if you need to scale up to large traffic
volumes. Our system (which has a hub and spoke architecture) has been
live for about 3 weeks and is currently doing about 100,000 messages
through the hub on a busy day. 

Given all the constraints we faced, I don't think any technology other
than ebXML could have delivered a viable messaging solution to this
industry; in conjunction with aseXML which has here demonstrated the
great strength of XML in providing a common data description language.

Dear all,

We are currently dealing with XML based transaction standards used in
environments with limited network resources. Is there an investigation
available dealing with efficiency of ebXML under time or limited network
resource constraints?

Thanks in advance for comments,

Daniel Kilper
