MPLS Gets Edgy in Austria

11:15 AM -- NEW YORK -- Ethernet Expo Americas 2011 -- Extending MPLS capabilities to the edge of the networks is something that some vendors have been touting for years and finally, it seems, it's an idea that's gaining some traction. (See Silver Server Deploys Telco Systems.)

Silver Server (not Silver Surfer) has deployed edge MPLS devices from Telco Systems (BATM) in Austria to help expand the capacity of its network and offer additional residential and business services without having to invest in additional edge routers.

Silver Server already has a Cisco Systems Inc. (Nasdaq: CSCO)-based IP network (comprising a number of 6500 routers plus ASR 1000s for B-RAS functionality) but has now added Telco Systems' T-Metro 7224 boxes for DSLAM traffic aggregation and backhaul at the edge of the network and to provide pseudowire capabilities further back in the network.

The vendor's VP of product management, Nir Daube, told Light Reading that the main attraction for Silver Server was not just the "cost-effectiveness" of the MPLS box, but its capacity (it's a pizza box with four 10GigE interfaces) and its ability to support up to 256,000 MAC (media access addresses), an important criterion for DSL service providers.

"In the past the only option for ISPs has been to buy more chassis-based, expensive implementations -- now there's an alternative," stated Daube.

And according to Telco Systems, demand for products that can take MPLS to the demarcation point at the edge of the network are in increasing demand to support mobile backhaul and enterprise services as well as fixed broadband deployments.
