Editor's note: China SDN/NFV Conference held in beijing, the conference around SDN/NFV discussion, from operators, service providers and other industry giants have participated in the CONFERENCE. Pei, Manager of Technical Strategy Department of China Unicom Technical department, delivered a speech entitled "thinking and Practice of China Unicom SDN/NFV ".Good afternoon, everyone! Let me briefly introduce and report on China Unicom's Thoughts on SDN/NFV . I was working on a corporate development strategy, so I borrowed the popular words from the internet, "the World is big, we have to look." I report the technical aspects of things less, mainly share, we go to the world to see some of the Results. About operators forNFVSome of the needs I have not said in Detail. NFVThis architecture is familiar to Everyone. so, for the north of the interface to consider a lot of people, the South interface is also concerned about, so we will pay attention to this work later. About theSDNand theNFVrelationship, some time ago to hear a more interesting metaphor: the wholeSDNand theNFVlike the operation of a company,SDNprovides the underlying infrastructure,NFVmore like human resources, Labor and other departments, some people to mention the demand,NFVthe network Computing and storage functionsSDNcome on, then when I'm done with the demand,SDNIt's a more interesting metaphor to do what you need to do with these NEEDS. next, share what foreign operators have DONE. Ntat in the SDN Go faster, It presents the famous " 2020 planning, This 2.0 not only for the network operation, but more importantly, its operation, operators are also worthy of reference. In addition to Australia's companies, it is more to start the mobile core network virtualization, that is, more fromMSand theEPCvirtualization of the core network, which isNFVExamples of Applications. In addition, Italy telecom, it does more work, at the level of access it realizes the cloud, in the fiber transformation and4Gin various areas it also has a cloud process, the entire cloud is managed, and its management system can be automated, self-optimizing management. In the field of mobile core network to do some planning, the level of access is basically not moving, but in the core network of the bearer layer and the following application layer are virtualized, while the enterprise application andCPare placed on the cloud and implementedRTroaming aspects are placed on the top of the cloud support, the level of access can be transmitted through. It has built a mobile core network for the internet of thingsVEPC, so that several nodes can be deployed to serve the Internet throughout europe, to theAt the end of each node already has5400Million's Capacity. Next to share the work of China Unicom later, according to the technical standards and the mature stage of the industry, the initial possible hardware can be left-hand, but the NFV or manufacturers fragmented, things to the interface did not get through, can only reach their own enclosure. Long-term goals and the vision of NFV , not only the bottom of the virtual control plane can be opened or can have a resource pool, to achieve the ultimate software hard Control. finally, according to the maturity of the technology to go down one step at a pace, the first step to carry out more easy to operate, like the mobile core networkEMS, andEPC, carry out testing, docking with existing systems to achieve end-to-end business opening up, Follow-up can put some likeCDNSystems are being virtualized for the time being, they are not considered virtualization for the access level,NFVPreliminary Consideration. For the entireEPCand network elements do some work, the next step to start the verification of testing, the organization of the entire product testing, while the interface, do some current network of pilot, while inNFVthis area, the application of the Internet of Things conducts some pilot and Validation. For home network management and enterprise network management virtualization, We have now developed the relevant standards, has carried out a related test, that is, in the home domain and corporate network management of this IPTV set-top Box considerations. The home network management has two evolution direction, a walk more thin one go fatter, to thin provide two layer of access on can, follow up add new business, home network management change make it Smallest. In addition, Unicom recently pushed the Unicom TV business, in fact, it put some of the business of a lot of control functions on the internet, for the follow-up to add other business is also more Convenient. Although the home network management and IPTV are different in the product form , but from the network,BVS content push can be considered together. The enterprise network management, for different sizes of enterprises, different needs to be able to respond quickly. To tailor the business to the enterprise, it is necessary to centralize the control management, or the higher level of this Ability. Next year, because on the basis of this year's various standards, the virtual network management system and business structure solidified, can let the parties in the industrial chain can be developed in accordance with unified STANDARDS. Follow-up is based on the needs of continuous improvement, further development of the entire network management of a series of related Products.Just mentioned the virtual home network management, It involves routers and some other work, follow-up through the End-to-end business to further Improve. Just introduced a fewNFVthe basic function, follow up with you aboutSDNsome of the Ideas. In theSDNfield, thanNFVmore mature, Then some basic related applications will be done first,SDNapplication set up a cloud company that plans 10 bases in the future, and the three bases currently in place have been deployed by CLOUD. Future in the field of optimization, as well as the return of the field will also Work. About theIPand light synergy, and the field of transmissionSDNdomain, Depending on the maturity of the technology, the access to the fixed network is not considered Virtualization. to SDN sdn at the beginning of the field, a large pool of resources may be formed at a later stage, and these different network elements can be placed in different resource Pools. For the entire future dc There is a tentative plan for goal planning, but we do not form a idc Span style= "font-size:16px;font-family: ' the song Body '; > Because the national network is very large, there are 300 multiple local networks, future idc After the initial positioning of the network in the beginning, in addition to support mobile backhaul, want to open the Enterprise users, now provide two-layer open capacity is very easy to achieve, but Unicom's situation is very special, we have two internal bearer network, one is the IP bearer network A , but it is the bearer network A connected to the bearer network B . then, how to get through the two nets, to achieve more than three layers of business access, which is our next consideration to solve the Problem. 650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/6C/06/wKiom1U92vHTA21IAAK__6HfFZU190.jpg "title=" 5.jpg " alt= "wkiom1u92vhta21iaak__6hffzu190.jpg"/>Just now, we have a brief report on some points. The follow-up is that we have also developed a future evolutionary goal. This is a long time, and it may take 10 years to reach that Goal. Maintaining independence in the field of access, forming a cloud at the access level, how the cloud is combined, is a follow-up consideration. Unicom to the north of the fixed network transformation, to change toMPS, then the two racks how to use, the local vacated room to form an access to the cloud, then the cloud is hierarchical convergence, how to achieve control, which is the focus of later research, the entire convergence and follow-up of the bearer network, because thereIPBearer NetworkA,B,169, we combined 10 large delivery centers with a carrier net, builtMS, on top of the bearer network, such as fixed-net and mobileMSHow to go, the final goal is to form a cloud, but there are a lot of problems to be solved from the process of cloud moving Forward. In addition to having these big own centers, we have BIT data centers in the 169 Network , our data centers and our data centers are co-controlled, how routes are distributed, and we have problems to move forward in this direction, Thank you! source of this article SDN/NFV Conference the shorthand draft of the meeting does not represent the viewpoint and position of the Site.
