What should network, data center and cloud expect

whether it is an arc screen 8K TV, a complex home robot, a cheap tablet computer, an innovative smart watch and wearable sensor fitness belt, a self driving electric car, or a UAV with a camera in high-altitude flight, people are excited. These are some essential gadgets for 2015. They were already on display at the Consumer Electronics Show (CES) in Las Vegas in January

however, if you want to know what is the most suitable for telecommunications in 2015, please forget the wearable and other connected gadgets. Let's talk about networks

if the traditional boundaries formed by data centers, closed buildings, campus networks and tunnels promoting wide areas are defined as boxes, 2015 will undoubtedly be a year for enterprises to break through the framework. We will see the arrival of the era of tipping point and software defined network [note], and the redefinition of security as a killer distributed application. This application is virtualized through the network function on SDN [note] Do not put the unused pendulum and its vicinity together to make it possible

we will see that intelligent service orchestration combines networks and systems. We will see that high-speed Metro interconnection becomes more and more popular and affordable. We will also see concerns about the increasingly chaotic service level guarantee that we should first know that the main component of wood flour is cellulose + lignin + hemicellulose. We will see IOT grow from a marketing slogan to a significant part of WiFi and 4G bandwidth

let's go into more details and highlight some of the participants and commentators of these trends

sdn is the basic promoter of borderless networks

the software definition network (SDN) is maturing and has created a revolution in operators and enterprise networks. The data plane of the network is separated from the control plane. SDN defines and redefines the network again and again

almost any conceivable architecture that can be imagined by operators or enterprises can be implemented in minutes, not months. Intelligence and connectivity can be distributed in one data center, in one telecommunications network, between two telecommunications networks, and around the world

The more mature of

and its wider adoption by the largest network companies make this technology ubiquitous. Take a look at niche companies like extreme network, which is at the forefront of SDN and fighting side by side with giants like juniper and Cisco

due to nfv[note], security has become a killer application based on SDN network

network function Virtualization (nfv) enables smart programmers to transform many network application functions, such as load balancing, caching and content filtering, into applications running on software defined networks. In my opinion, security is one of the most important functions that can be implemented through nfv, because you can now embed security functions and security policies into every appropriate SDN based device

in the past, for example, it may not be cost-effective to put the most advanced network security equipment together with each switch and router. With secure nfv, this is almost an easy task. One company guarding in this field is wedge networks, which not only has a strong product suite, but also defines a security specification called nfv-s or network function virtualization with sprint communications, a testing service company. Other companies, including Palo Alto and F5, are also working to introduce security into nfv. Or is that the introduction of nfv into security? This is a bit of both

life cycle service orchestration (LSO) will enable SDN and nfv to access from all levels

the complexity of the network may be incredible. Consider the challenge of defining new services. Whether through traditional network devices, devices with SDN functions, or hybrid enterprise or operator networks, these new services can be created and implemented. You must also manage these services, ensure that they comply with service level guarantees, bill them, and then dismantle them when they are no longer needed

is the key to creating and managing services in a complex environment, especially when SDN and nfv are part of the composition. Defining LSO functions and supported APIs is crucial for overcoming the challenges of today's operation support system (OSS) and bridging the gap with sdn/nfv functional networks in the future. Lso can provide instruments for every place in the network, not only realizing services, but also collecting data in real time to enable real-time visualization and management. In fact, you can think of LSO as a collection of the best traditional network consoles and big data analyzers. An excellent example here is cenx, whose cortx service choreography? Can take over modern network end-to-end lifecycle management, and help with migration and SLA implementation issues

an important and farsighted measure in this regard is MEF's class III network, which combines on-demand flexibility and the universality of interconnection with the performance and security assurance of Carrier Ethernet 2.0 (CE 2.0). The third type of network service promises to provide a dynamic, cloud centric experience, an unprecedented level of user control over network resources, and choreographed connections between physical and virtual service endpoints and across multiple providers. MEF's third type of networking initiative includes the establishment of interoperability specifications that suppliers can use to orchestrate, share, and combine, uh, resources across everything. The scope of MEF includes network equipment manufacturers, software companies, telecom operators, data center suppliers, cloud service providers, and even computer manufacturers. MEF is working with CEF and other industry stakeholders forming MEF unite action to define the necessary LSO and management capabilities to achieve the key objectives of the third network

high speed metropolitan area network will drive enterprise connection

let's look at the big picture. An enterprise can operate all the optical fibers it wants to pass through its buildings or around its office parks. If you connect directly to, say (+ networkworldweixin), what about the cloud based data center Ethernet? Too frequent connections are fast, but they are not fast enough to push down the performance wall between enterprise data centers and cloud centers, or between different cloud providers

high speed interconnection based on optical technology is the core of modern cloud data centers [note], and also the connection between those data centers and their performance driven enterprise customers. One of the leading manufacturers in the high-speed metro area is infirra, which has set up a stake with high performance, low power consumption and impressive port density. For example, check out a new product series called cloud Xpress, which is specifically designed for the metropolitan cloud, which is a virtual transmission network that interconnects multiple data centers in the metropolitan area

service level guarantee will drive everyone crazy

almost every enterprise relies on some type of cloud service. These are the performance of XXX as a service, whether it is infrastructure, security, analysis, virtualization, storage, etc. Next year we will continue to see the proliferation of everything as a service with fuzzy boundaries. Organizations such as the cloudethernet forum are working to standardize the definition of cloud services, but the reality is that it will be difficult for enterprise CIOs and service provider marketers to speak the same language

prices have fallen sharply, while service utilization and complexity have soared. What does that mean? Crazy service level assurance will be difficult to understand, measure and implement, especially when many of these SLAs are across multiple service providers. Detached cloud. Interdependent APIs. Unpredictable performance and availability. The European Commission is studying cloud service level agreement standardization guidelines as part of its Europe 2020 plan. This cannot come too soon, and with luck, we will see the real global standard take shape in 2015

IOT will begin to consume huge bandwidth and other back-end resources

today, a large number of IOT equipment fitness belts, smart watches, home thermostats and smart TVs are just the beginning. Many wearable devices communicate with intelligence through Bluetooth; Applications on the cloud communicate with the cloud, but there won't be too many packets. The same is true of other lot devices located at home or in the office, which communicate with routers via WiFi or (rarely) physical cables. Remember those?

nowadays, IOT is almost unmeasurable. This situation will change and grow. Equipment equipped with satellite navigation/gps function frequently sends location information; These are small pieces of information, but some small enterprises cut corners and substitute inferior products for good ones. However, there are a large number of unqualified products. Devices equipped with cameras will send data into the cloud. This will be a large amount of data. Think of Netflix in the reverse direction, and there is no benefit of edge caching. More mobile devices will have their own cellular data connections. A study published by New York University Institute of technology at the end of 2013 highlighted the exponential rise in bandwidth consumption of IOT between now and 2020. A report from campus technology cited Gartner's prediction that the number of IOT devices will increase from 900000 in 2009 to 26billion in 2020. The following is a quote from the report. How will the park [note] network handle the 26billion devices of IOT

the deployment of IOT will generate a large amount of data that needs to be processed and analyzed in real time, pointed out Fabrizio Biscotti, research director of Gartner. Processing a large amount of IOT data in real time will increase with the proportion of data center workload, making providers face new security, capacity and analysis challenges

this is a thought that many IT managers [note] and cloud providers may not think of. Equipped with SDN, light up the metro optical fiber, and pay attention to what happens in CES, because all those large-scale distributed data packets will attack our network
