The market for high-performance software-defined core networks has been rapidly growing in recent years. As businesses and organizations increasingly rely on digital infrastructure to support their operations, the need for efficient and flexible networking solutions has become paramount. Software-defined networking (SDN) has emerged as a game-changer in this space, enabling businesses to create agile and scalable networks that can adapt to their evolving needs. A software-defined core network refers to the central infrastructure that connects various components of a network, such as servers, routers, and switches. Traditionally, these core networks were built using proprietary hardware and software, which limited their flexibility and scalability. However, with the advent of SDN, businesses can now leverage virtualization and automation technologies to create software-defined core networks that are highly efficient and adaptable. One of the key advantages of high-performance software-defined core networks is their ability to handle increasing data traffic. With the proliferation of cloud computing, IoT devices, and streaming services, network traffic has skyrocketed in recent years. Traditional core networks often struggle to handle this surge in data, leading to bottlenecks and performance issues. In contrast, software-defined core networks can dynamically allocate resources and prioritize traffic based on real-time demands, ensuring optimal performance even during peak usage periods. Another significant benefit of software-defined core networks is their cost-effectiveness. By decoupling the network’s control plane from the underlying hardware, businesses can reduce their reliance on expensive proprietary equipment. Instead, they can leverage commodity hardware and virtualization technologies to create a more cost-efficient network infrastructure. Additionally, the centralized management and automation capabilities of SDN reduce the need for manual configuration and troubleshooting, further lowering operational costs. Moreover, high-performance software-defined core networks offer enhanced security features. With traditional networks, security measures are often implemented at the perimeter, leaving the core vulnerable to attacks. In contrast, software-defined core networks enable businesses to implement security policies and protocols throughout the network, including the core. This distributed security approach provides better protection against threats and ensures that critical network resources are safeguarded. The market for high-performance software-defined core networks is being driven by various factors. The increasing adoption of cloud computing, the rise of edge computing, and the growing demand for network virtualization are some of the key drivers. Additionally, the need for network agility and scalability to support emerging technologies such as 5G, artificial intelligence, and the Internet of Things is fueling the demand for software-defined core networks. Several major players in the networking industry are actively investing in the development and deployment of high-performance software-defined core networks. These companies are leveraging their expertise in SDN, virtualization, and automation to offer comprehensive solutions that address the evolving needs of businesses and organizations. Additionally, startups and niche players are entering the market, introducing innovative technologies and disrupting traditional networking approaches. In conclusion, the market for high-performance software-defined core networks is experiencing significant growth as businesses seek more efficient, flexible, and scalable networking solutions. The advantages of SDN, including improved performance, cost-effectiveness, and enhanced security, make it an attractive option for organizations looking to modernize their network infrastructure. With the increasing demand for cloud computing, edge computing, and network virtualization, the market for software-defined core networks is expected to continue its upward trajectory in the coming years.

The VMware Inc invention works as follows

A method consisting of instantiating virtual routing (VR) at each node that forms a network. Each VR is connected to the network as well as to a node tenant. The network consists of virtual links within an overlay network that is provisioned on top of an underlay network, which includes servers from a public network. The method includes configuring a VR with a feedback system that contains at least one objective feature of the network. The method consists of configuring the VR so that it receives link state data for a set virtual links and controls the routing of tenant traffic flows according to the best route of network determined by at least one objective functions using the link data.
