Cisco Enhances Network OS for Service Providers
The improvements to IOS NX and the addition of three Internet routers are designed to help service providers create cloud-scale networks.Cisco Systems officials are enhancing the capabilities within the vendor's IOS XR networking operating system to enable service providers and cloud operators to more easily deliver applications to customers and drive down the cost of their networks. The improvements to the network OS are designed to make networks more programmable and to enable service providers to converge their data center network and WAN architectures. At the same time, IOS NX now offers greater integration with such IT configuration and management tools as Chef and Puppet, open innovation via an IOS XR software development kit (SDK) and Cisco's DevNet Developer Program, and more predictable programming of the network through APIs. The networking vendor also is rolling out three new systems in its portfolio of Network Convergence System (NCS) Series routers. The new offerings, which will become available in December, come as service providers continue to struggle with the rapidly growing amount of cloud-based network traffic, according to Cisco officials. According to Cisco's numbers, worldwide data center traffic will triple by the end of 2019, from 3.4 zettabytes last year to 10.4 zettabytes. In addition, 83 percent of total data center traffic will come from the cloud by that year. By comparison, 61 percent was cloud-related in 2014.
The Internet of things (IoT) will contribute to that growth. Cisco expects the number of connected devices, systems and sensors to jump from 25 billion last year to more than 50 billion by 2020. That combined with the growing storage needs driven by the demand for more scalable services and applications will drive the convergence of the data center and WAN, company officials said.
