On May 22, 2019, the 3rd Future Network Development Conference washeld in Jiangning Future Network Town, Nanjing. The theme of theconference was "Network Global, Win the Future", while last year'stheme was "Innovation, Leadership, Future". If we are still in theturbulent period of transition in 2018, after one year's practiceand precipitation, both the government, global operators, equipmentmanufacturers, relevant representatives and leaders of Internetcompanies, as well as experts and scholars in the field of network,have a better understanding of the needs and concepts of futurenetwork, industrial chain and ecological cooperation.
Last year and this year, what remains unchanged is the infinitefuture and the common pursuit of the future network, and whatchanges is the new needs and challenges that arise withpractice.
From more than a decade ago, when we realized that the Internet wasgoing to change, to the establishment of Jiangning Institute ofNetwork Innovation in the future in 2011, and to the present"decisive" moment, there may be some differences on the specificrealization of white box, marginalization, virtualization and otherbusiness issues, but the existing network system has reached aninevitable moment of change, on which all the colleagues of theGeneral Assembly have reached agreement.
IP Overburdened Needs to Update the System by SubversiveMeans
The first problem is the architecture. Modern network can no longercarry data exchange in the era of big data and AI. The structuredecides the nature. According to Wu He-quan, academician of ChineseAcademy of Engineering, network protocol (IP) only considerssupporting connectionless data communication at the beginning ofits design. This is the weakness of the original communicationnetwork, and the data traffic in the network at that time accountedfor a small proportion. In addition, IP open architecture can beoperated on any digital network (including circuit-switched SPCtelephone network). There is no special requirement for theunderlying communication facilities. It has a wide living space.Moreover, the Internet has begun to be small and there is nopressure for commercialization.
But now, the network is becoming more and more responsible, IP isforced to bear the data needs of the whole world. It takes bothtime and human and financial resources to start on demand andrepair the evolution route. The accompanying problems ofextensibility, security, network service and quality can not beignored. Therefore, "we prefer to rely on the revolutionary lineand use subversive technology to update the existingsystem."
Of course, change does not mean that all this, the reality of theoverall transformation program is difficult to verify. According toCisco's white paper "Global Cloud Index: Forecast and Methodology(2016-2021, White Paper), released at the end of last year, mobileIP traffic accounted for 11.03% of the total network IP traffic in2018, and the impact of the transformation of mobile network systemon the whole network was not particularly significant. Therefore,in today's "mobile traffic proportion is not high", just as VoIPhas subverted the penetration of traditional telecommunicationnetwork technology, Wu Hequan believes that "5G can be used as thebreakthrough point of network reform."
The demand of 5G application scenarios for UWB, Dalian connection,low delay and high reliability also echoes the basic requirementsof the future network system. The three characteristics of 5Gnetwork forwarding, cloud and virtualization can correspond to theintegration of communication and computing, the collaboration ofcloud management functions and the decoupling of hardware andsoftware. They are not separated from the IP system, nor are theylimited to the IP system. They include various new networkarchitecture, such as information center network, servicecustomization network, and so on. They completely change theworking mode of the existing TCP/IP network. It includes all kindsof key and hot technologies related to the network, such as newnetworking technology, network protocol upgrade, as well as newtechnologies such as artificial intelligence to solve the existingnetwork problems.
This open system, which integrates "evolution and revolution", canensure that new business needs are met in the short term, and thatthe existing network problems are solved comprehensively andthoroughly in the long term, so as to promote the development ofthe digital information society.
Change with Pain and Innovation
But change also means the game of interests between upstream anddownstream parties. He pointed out that for operators, this is alsoa difficult choice, and they need to face the challenge oftechnology and management process reengineering at the sametime.
Taking edge computing, one of the core technologies of 5G as anexample, as an important direction of the future network, dataservices can be handled quickly and automatically near the userside, which makes the data interaction between mobile communicationnetwork, Internet and Internet of Things more convenient andflexible, makes operators more close to users, solves the problemof service rigidity of operators by a large margin, and avoidsoperation. However, the diversification and fragmentation of accessand business needs will al
