Cisco is a multinational technology corporation that designs and sells networking, security, and collaboration products and services. It’s considered one of the most well-known and respected brands in the technology industry. However, in recent years, some experts have argued that Cisco is becoming obsolete in the face of new technologies and changing market trends. 

One of the main arguments for the obsolescence of Cisco is the rise of software-defined networking (SDN). SDN is a new approach to networking that allows for the abstraction of network control and forwarding functions from the underlying hardware. This makes it possible to manage and control networks using software rather than traditional networking hardware. Some experts argue that this trend is making traditional networking hardware, such as Cisco routers and switches, less relevant. 

Another trend that is said to make Cisco obsolete is the rise of cloud-based networking solutions. Many companies are moving their networks to the cloud, and as a result, they don’t need the same level of on-premises hardware as they did in the past. This shift is making traditional networking hardware less necessary. 

Additionally, the rise of open-source networking solutions is also seen as a threat to Cisco’s dominance in the market. Open-source solutions like Open vSwitch, Quagga, and BIRD are becoming increasingly popular among network administrators, and they are seen as more flexible and cost-effective than proprietary solutions like Cisco’s. 

However, it’s important to note that Cisco is still a major player in the technology industry and it’s not likely to disappear overnight. Cisco has a large customer base and an extensive portfolio of products and services that are still in demand. Additionally, Cisco has made efforts to address the trends that are said to make it obsolete by investing in software-defined networking, cloud-based solutions, and open-source technologies. 

In conclusion, while some experts argue that Cisco is becoming obsolete, it’s important to recognize that the technology industry is constantly evolving and changing. Cisco has been successful for many years, and it’s not likely to disappear overnight. However, it’s important for Cisco to adapt to the new trends and technologies that are emerging in the market in order to remain relevant in the future.
