Ericsson is fielding a line of packet optical gear designed to address the expected surge in metro networking. The new products will support a T-MPLS control plane, but Ericsson plans to upgrade to the more modern MPLS-TP and is also considering PBT (PBB-TE).
Metro capacity may be driven by a host of factors in 2009 and 2010 and the operators may be more interested than usual in the optical layer. This has implications on the Carrier Ethernet and IP MPLS wars since optical spending tends to encourage operators to deploy some control plane architecture, and that could then pull through either switches or routers.
