Title: הודעה



To name a few more vendors that I am aware of that are capable of doing CES over packet networks that have not been mentioned by others.

 

1. Luminous Networks (http://www.luminous.com)

2. Zarlink (http://www.zarlink.com)

3. Overture Networks (I don't know their website top of my head)

 

and whole bunch of other companies. BTW, I work for Luminous Networks (standard disclaimer).

 

I can't speak for other vendors but I can speak for Luminous. The systems have been deployed for the past 4 years in networks around the world. One of the service offerings by Luminous is TDM and PDH emulation over RPR networks using MPLS. The definitive way to qualify CES products is to check with the GR-253 and other Telcordia specifications.

The only product I've seen is the RAD IPMux (which looked quite good), check www.tdmoip.com for latest status on RAD MPLSoIP. However, Axerra promote CESoIP (http://www.axerra.com/cesoip_whitepaper.pdf), and sell their AXN Multiservice Packet concentrators and Access Devices, but I dunno how good they are.

I would like to add to khan question.

 

Sometimes you need to transport L1 traffic and not hdlc. for example if you want to transport a voice tdm E1 over a packet network.

In this example you need to transport the G.703 and not the PPP or HDLC layer.

The only implementation i'm aware of is RAD IPMUX device.

As far as i know this solution works only betwen two RAD devices and they encapsulate the G703 over ip and let the ELSR to do the mpls encapsulation of the ip packets. i don't think they encapsulate G703 directly into an an mpls frame.

 

 

Does anyone know of any other implementation?

Dear Khan

I guess, u intend asking for transporting L2 Traffic like Ethernet/Frame-Relay/HDLC/ATM, using SDH/SONET as Physical Mode, over MPLS Cloud[like Cisco ATOM; Any Transport over ATM based on Martini]. If so, yes there are carriers who are implementing or implemented such commercial services[like Metro Ethernet/Vlan].

I am sure, this distro will share more valuable inputs.

Hi folks,
Are there any recommended solutions around for transporting SDH/Sonet traffic over a packet/IP/MPLS based networkk.
I believe the PWE3 WG has been working, using the martini drafts on transport over MPLS. Is there any commercial implementation done yet?

Thanks,
Amjad
