Coriant, a supplier of metro-to-core transport solutions, has announced the latest progress in its collaboration with Juniper Networks to create an integrated packet transport network (IPTN).
Recent joint R&D between the two networking innovators resulted in the first multi-vendor line side interworking between router and DWDM system suitable for long haul (LH) transmission.
This will enable network operators to efficiently deploy a converged packet optical infrastructure that increases network capacity while lowering costs. The IPTN solution provides the foundation for faster and more reliable services optimised for high bandwidth applications driving network growth.
The IPTN solution is a combination of the Coriant hiT 7300 DWDM system, Coriant TransNet planning tool, and TNMS network management system with industry-leading Juniper Networks MX Series and PTX Series routers. The latest interoperability test was carried out on line side interworking of PTX 100G DWDM interfaces with hiT 7300 transponders and line system. The results highlight new use cases in seamless packet optical networks, which now include regeneration of router interfaces and handoff between routers from different vendors, which were not previously attuned on the line side.
‘We see this collaboration between Coriant and Juniper as an important step that allows operators to offer reliable and scalable networks for richer services to its end-users by a tighter integration of the IP/MPLS and optical network layers,’ said Uwe Fischer, chief technology officer at Coriant. ‘Both companies are highly motivated to create integrated packet network transport solutions to contend with the exponential growth in data and to offer long-term support to our customers from now and well into the future.’
