Sony’s newest IMX789 image sensor will be a temporary Oppo exclusive

The result of cooperation between Oppo and Sony will not only be that the Sony IMX789 will appear initially in smartphones of the Chinese manufacturer

Oppo has unveiled a new Sony image sensor called IMX766 in its latest smartphone, the Reno5 Pro+ 5G. Chinese sources claim that the two companies continue to collaborate on the development of the new Sony IMX789 image sensor.

Initially, it will be used in the flagship smartphone Oppo Find X3. It is reported that the Sony IMX789 will be a direct successor to the IMX689, which is used in the Oppo Find X2 Pro. This sensor has an optical format of 1/1. 43”, its resolution is 48 MP.

Outdated infrastructure
One of the advantages of NFV is the ability to reduce capital costs (CAPEX) and operating costs (OPEX), as well as reduce the time spent by administrators on managing data centers. Nevertheless, outdated networks have become a serious problem for the creation and development of NFV. Some older hardware versions will not be updated to support this technology. Despite this, some applications for network virtualization will also work on the outdated network infrastructure, allowing Telecom operators to launch NFV now, and invest the resulting profits in more complex projects related to NFV.

Security issues
The more new network features NFV provides, the more new risks they carry. Software is inherently less secure than hardware. Both routers and firewalls on specialized hardware are harder to crack. Also, the software is more susceptible to distributed denial of service (DDoS) attacks. It is necessary to carefully protect the platform from constant threats, monitor updates and prevent the use of old versions that contain” holes ” in security. The virtual network hypervisor must ensure a high level of isolation of the machines, so that if one of them is infected, the virus cannot move to the others.

Lack of standards
Another major challenge facing the virtualization market is the need to create standards for communication between NFV components. The development of such standards usually takes several years, but the telecommunications industry is already ready to start deploying and cannot wait that long. Standards should be prepared by the European telecommunications standards Institute (ETSI), which is the main driver of standardization in the market. In parallel, standards from other associations were proposed, but no General consensus was found. Operators can participate in the development of these standards through the ETSI Industry Specification Group, which is available to both its members and other companies.

Not enough big business cases
Another obstacle to the development of network virtualization is the lack of well-developed and implemented business cases. Sellers try to idealize NFV and describe even those functions that cannot be implemented with it. This leads to the frustration of the Telecom operator when implementing when it is faced with limitations of capabilities. On the other hand, some suppliers are not confident in NFV-based solutions and do not try to be convincing in their proposals, leaning towards the classical network architecture. In addition, some of the benefits of this technology, such as fast startup, network optimization, and innovative features, are difficult to measure, which makes it even more difficult to describe good business cases. The technology must be implemented and describe your experience, otherwise it will be difficult to promote it in the market.
Fortunately, all the described difficulties are surmountable. Each new technology in the initial stages of its development has pitfalls and childhood diseases that are eliminated when large-scale projects are deployed. The same fate awaits the NFV.

It is very important to keep up with the times and use modern technologies such as NFV for building networks and DPI for traffic management.
