Building carrier-grade packet transport networks doesn’t need to be so expensive. By extending MPLS-TP to the metro and by providing multidimensional flexibility to handle a variety of traffic types, protocols and interfaces, you can lower
your TCO without compromises on quality or
services. Read More
