Promote 5G and IOT landing operators need solid foundation

Date:2017-05-31 14:15

As we all know, mobile data traffic is exponential explosion trend, the popularity of smart phones means that more and more video services, traffic demand is higher and higher.

Most telecom operators choose 5G. It is expected that the successful landing of 5G will further stimulate the consumption of mobile users in the few years, which requires telecom operators to carry out more fiber deployment.
      In addition, the IOT  will also have impact on the market. Billions of mobile devices , sensors, smart grids, smart homes, car networking, and a variety of other data sources , all of these will connect IOT to tens of billions. The latest CISCO VNI forecast shows that the number of devices connected to the network will grow from 7 billion 900 million in 2015 to 11 billion 600 million in 2020, most of which will come from the IOT.
       All of these flows need to be processed in the data center. CISCO's global cloud index estimates that the global data center traffic will be 5000 trillion bytes in 2016 and will grow to 10400 trillion bytes in 2019. This will force data center operators to substantially expand their data center network infrastructure and ensure that it is fast, efficient and automated, and that automation is the only way to make it work. 
      Meanwhile, the forward-looking data center operators are trying to use leaf-spine architecture to support high level data center East-West traffic. Than the three layer architecture is more efficient at the same time, it also brings more need to connect the number of test and management of the server is connected to the top of rack through the optical fiber (ToR) and ToR switches, leaf-spine switches connected by a single-mode fiber, optical fiber connection path is redundant backup.
      In line speed migration from 10G to 100G and future 200G-400G, these fiber links require more accurate loss budgets and reflectivity requirements. Companies using web-scale have imposed price pressure on optical transceivers and pluggable devices, forcing suppliers to streamline their product features, which could lower product quality. To mitigate this risk, operators need to make sure they pass failure tests and the cleanliness of fiber connectors.
       Telecom operators are also beginning to adopt NFV, which currently runs virtualized functions on dedicated hardware on standard IT server platforms and manages it using the IT automation system. You've already seen the flexibility and agility of web-scale operators through the cloud and wait for the final realization of virtualization capabilities. This shift does not demand development - the waterfall flow has not been able to meet the high speed, and operators are considering adopting the same DevOps scheme as web-scale.
       Of course, all changes are likely to increase complexity and risk. Automation gives operators high efficiency while requiring extensive testing to enhance visibility and analysis capabilities of the next generation of service assurance and surveillance systems. Because the physical and virtual resources are highly distributed, the end-to-end view is critical.

In order to better occasion 5G, IoT and NFV, operators must in each stage of virtualization, automation and DevOps of infrastructure, services and steady flow.
