New research has suggested that generalised multi-protocol label switching (MPLS) network technology is increasingly being used in optical networks.
The survey by Infonetics Research was focused on identifying levels of demand for IP over dense wavelength-division multiplexing (iPoDWDM), as well as generalised MPLS and MPLS transport profile functions on routers.
It revealed that generalised MPLS is now being embraced by operators, although it is thought some carriers could be holding back to consider its success in the data domain.
The study also suggested that the adoption growth for MPLS-TP on routers is expected in 2013 or later.
Discussing the findings, Michael Howard, principal analyst and co-founder of Infonetics Research, said: "The main driver for IPoDWDM is cost savings by using less expensive coloured optics on routers instead of expensive optical-electronic-optical transponders on both ends of the router-DWDM connection."
Previous research by Infonetics revealed that the worldwide IP MPLS virtual private network and Ethernet services markets grew during 2009, despite the impact of the economic downturn.
