Yes dear,  I agree with you. To my best knowledge we can not directly map L1/TDM TO mpls, only TDM-Over IP Solution seems to be available through RAD's IPMUX.

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
