As service providers continue to roll out new services over existing overlay networks, network complexity and costs have skyrocketed. Network operators need to be able to aggregate and switch their service, without adding any additional complexity. Furthermore, the growth of IP/Ethernet, video, and storage services alongside the legacy TDM business is driving the need to converge the network and the services using service-aware technology. This technology combines optical intelligence and reliability with the ubiquity of Ethernet to reduce cost and complexity.
Challenges
Network operators are utilizing SONET/SDH, Ethernet, and more recently, OTN-based infrastructures to help manage services growth. Legacy services provide the cash flow, but new services provide revenue growth. These new services are being converged at the edge of many Metropolitan Area Networks (MANs), driving the need to aggregate the services from various sources and switch them across any available Wide Area Network (WAN) to their end destination. Across the WAN, services must be switched granularly to the end destination, which could be an MSPP, Ethernet switch; or even routers. This switching must be accomplished while reducing capital and operational expenses.Solution
Intelligent multiservice optical switching systems support any service, incorporate service awareness and automation, and combine multiple functions into a single system that can help cost-effectively aggregate and granularly interconnect services across a SONET/SDH, Ethernet or OTN-based core network. These systems must also offer native Ethernet interfaces, significantly lowering the cost of interconnection. Simplifying the network by replacing multiple ADMs, MSPPs, and digital cross-connects with a converged network element reduces routers and Ethernet switches and increases capital and operational savings.Ciena's offerings
