Telefonica’s Research and Development division (Investigación y Desarrollo, I+D) has tested a dynamic IP Optical Multilayer network architecture with Juniper Networks. The aim of the GMPLS-based IP Optical infrastructure is to reduce complexity in the service provider network while improving the economics of supporting the increasingly unpredictable traffic patterns driven by new and emerging network applications.
Telefonica has developed this solution leveraging the Junos control plane running on Juniper Networks core and edge routers and had previously demonstrated this capability at the Optical Fiber Communication Conference and Exposition (OFC) 2011 in Los Angeles.
“We are working on defining how networks should be built in the next five to ten years, and the coordination of the IP and Optical layers is a fundamental pillar of this next generation architecture,” said Enrique Algaba, technology director, Telefonica I+D. “Our collaboration with Juniper Networks to test this architecture model has been very fruitful in demonstrating what the new network of the future could achieve.”
“Telefonica I+D has clearly identified a key capability required to build and maintain economical and more efficient core transport networks, namely the intelligence to coordinate resources in the IP and Optical layers,” said Luc Ceuppens, vice president of product marketing, Platform Systems Group, Juniper Networks. “The ability to dynamically adapt the network to actual traffic patterns and identify where traffic should be aggregated is essential for service providers to minimize network resource consumption, without compromising service reliability or reducing quality of experience for their end users. This is the philosophy behind Juniper’s new Converged Supercore architecture which combines the inherent efficiency of MPLS with the simplicity of switching and integrated optics to deliver unmatched network scale with fewer network elements without compromising service reliability.”http://http://www.juniper.nethttp://www.tid.es
- In March 2011, Juniper outlined a new architecture that calls for a single network management system for the entire transport network — Junos — for both the optical layer and the packet layer. The aim is to combine the efficiency of MPLS, the simplicity of switching and integrated optics to deliver network scale with fewer network elements.
By collapsing the packet and transport network layers, the Converged Supercore would help carriers save money in network management and operations, while taking uncertainty and cost out of core network provisioning. Juniper is forecasting network CAPEX cost savings of 40 to 65 percent compared to traditional architectures and a 35 percent savings versus a pure IP routing solution.
The new Converged Supercore switches are based on a new Junos Express chipset that is optimized for high capacity transport and features the on-chip traffic engineering, full delay bandwidth buffers, algorithms optimized for packet transport and embedded error detection required to support differentiated traffic types and patterns without disruption. Junos Express is built in 40 nanometer technology with 3.55 billion transistors. It represent an R&D investment of $40 million. Junos Express is the second chipset in the Junos One family of processors, which the company developed in-house.
