What makes you bright? Interpreting the dispute between ODL and onos

controller integration trend is a very important step in the development process of Sdn. The dispute between ODL and onos has quite a bright plot of the three countries. At present, onos, which is highly expected by telecom operators and equipment manufacturers, needs to work harder to catch up with the more mature ODL

SDN development lifeline: controller integration should be accelerated

SDN breaks the original network architecture and has a profound impact on the pattern of the industrial chain. Therefore, from the beginning of its birth, SDN controller has become the target of public criticism. At present, the industry has been the first to launch SDN controllers such as opendaylight (ODL), opencontract, Ryu, and floodlight

at present, the reason why manufacturers have not formed a market is that the current SDN is not what many users think they want. SDN itself may not be a selling point. On the contrary, SDN is just a catalyst to improve operational efficiency and add new functions

in fact, the value of SDN to operators is very similar to 4G. It is naturally a thing that can help network operators save money and make money, so it is easier to be accepted by operators, and even no matter how much it costs, someone will be willing to do it. However, it cannot be directly realized as the ability to make money. Only by realizing new value through business innovation can it generate the possibility of profit. It also requires the joint efforts of the industry to continuously explore the commercial value of Sdn

as Wei Leping, director of China Telecom Science and Technology Commission, said, the development of sdn/nfv is still in its infancy, the technology is not mature, and the progress of standardization and commercialization is still slow. Sdn/nfv deployment is destined to be a long-term development process, and will not be rewarded in the short term like 4G network deployment

sdn, as a long-term investment, has poor liquidity, so operators will be extra cautious when investing. As the catalyst of network function, operators have higher expectations for Sdn. However, at present, there are many SDN controllers, which limits the rapid development of Sdn

the industry point of view points out that too many SDN controllers have hindered the popularity of SDN in enterprises. Because in the initial stage, few enterprises will bet on a certain SDN controller, and the integration means that enterprises can choose to bet on a certain controller for long-term operation

as Neela Jacques, executive director of opendaylight, said, all telecom operators hope to have a super controller at the top of the network, so that they can have a full view and a very good understanding of the whole operation, which can make their network more flexible, open and programmable. Therefore, operators' bets will be more cautious

with the continuous development of the industry, there is a gradually clear trend in the SDN controller market, that is, the integration of controllers. Although there are still many different types of controllers, there are two that have attracted much attention at present. One is the opendaylight (ODL) project of the Linux foundation. The other is B's open network operating system (onos)

manufacturers interested in interoperability will also be affected by too many controllers. However, as ODL and onos are widely accepted, manufacturers can choose one of them to develop their own controllers. Even some SDN application developers have long taken a wait-and-see attitude, because to support an application that can run on a variety of controller platforms, the cost of time and capital will not be less

once the whole industry is basically stabilized on ODL and onos, application developers can launch corresponding products for these platforms. It can be said that the trend of controller integration is a very important step in the development process of Sdn

zhaohuiling, chairman of the network and switching Technical Committee of China Communications Standardization Association, said that operators and manufacturers jointly promote the development of the industrial chain and make SDN controllers develop in a more standardized direction

odl and onos dispute, both Yu and he Shengliang

as the two major competitors of SDN controller, the relationship between ODL and onos is similar to Yu Liang in the Three Kingdoms, both Yu and he Shengliang

at present, the impact of ODL is still more extensive than that of onos. ODL is an open source controller project launched by Cisco, IBM, Microsoft, NEC, juniper and other communication and it giants. At present, ODL has been unanimously recognized by many enterprises in the industry, and has developed a new soil remediation material based on ODL into Guangdong. Lead and cadmium pollution is expected to be controlled, and the commercial deployment of SDN has been carried out

neela Jacques said in an interview with c114 that opendaylight is actually the largest and most successful SDN focused project in the networking industry. ODL is a global community, and the region it crosses is an area where the sun never sets

analysis shows that among many ODL users, 30% are Internet service providers, 25% come from research institutions and various colleges, 17% are end users, and the remaining 28% are ecosystem providers; ODL is mainly used in a wide range of fields, such as innovative business value, network application, ecological construction, etc

no matter Tencent or China Mobile, I heard that they all hope to participate in ODL more and make contributions to ODL in addition to using ODL. They also hope that manufacturers can actively use participation and make contributions to the development of ODL

however, since ODL is an open source controller dominated by it equipment providers, telecom operators and traditional telecom equipment providers such as Huawei and Ericsson will not buy it. They hope to take the lead in the evolution of Sdn. Onos provides them with the opportunity to find the development space of polyurethane insulation materials mainly used in buildings and gradually increase their leadership

onos is a non-profit open source community organization initiated by well-known universities such as Stanford and Berkeley, which first invented SDN technology, together with operators and equipment manufacturers. Its goal is to create an operator level open source SDN network operating system to meet the needs of operators to migrate to Sdn. Some analysts pointed out that many operators are willing to accept onos because it can provide operators with agility and flexibility, and may make them get rid of the shackles of equipment suppliers

as a key point of onos attacking ODL, opendaylight can provide operator level performance. The answer from Neela Jacques is definitely yes

hundreds of engineers are constantly committed to improving the performance of ODL products, and there will be a major new update every six months. In addition, we have also improved the availability of ODL and supported openstack, which is crucial to cloud technology and nfv technology. In addition, at the request of operators, ODL has also added a new capability to support applications written by them for other platforms on opendaylight. Neela Jacques proudly said that in fact, our SDN flat affects the test and produces water rust The platform can support a very wide range of users, but also can support a very wide range of application cases. Users can use ODL to realize the automation of service provision, and also help users use ODL to optimize their network resources, optimize existing network resources, and do not need to buy additional new equipment

compared with onos' rapid ritual update of product versions with little difference, each version update of ODL is extremely awesome. In addition, in terms of business cases, ODL can dump onos for several blocks. Neela Jacques added that whether at t or China Mobile, they will deploy some node controllers, and ODL is their very good choice

John Donovan, senior vice president of at t, pointed out that the goal of at t is that open source accounts for more than 50% of the code by 2020. It can be said that the choice of ODL is a strategic choice for at t. Neela Jacques revealed that the commercial deployment of China Mobile ODL will be further accelerated next year

when talking about the relationship between onos and ODL, Neela Jacques said frankly that the success of onos in some fields is not a bad thing for us. In fact, it is a very good competition, which enables us to deliver services faster. ODL pays more attention to southbound code and protocol, and onos pays more attention to openflow, but they also find that users actually have a lot of southbound needs, so they also begin to use languages like Yang to borrow something from us. At t has now used ODL to solve their existing problems. With onos, they hope to rebuild their central exchange, mobile edge computing, etc. to innovate and develop new plastic materials and new processing technologies

for the comparison between ODL and onos, Wei Leping believes that onos needs to work harder to catch up with the more mature ODL. Zhao Huiling said that ODL and onos have their own advantages. Operators need controller interfaces to be open, easy to call and easy to expand. For the needs of operators, both ODL and onos need to further improve their functions

it can be said that the dispute over SDN controller will accelerate the maturity of SDN industry
