The legacy network

The legacy network

Welcome part 1 why network & why legacy

To retain their market share, service providers are implementing new appealing technologies to end-users, which necessitates changes to their existing infrastructure (also known as legacy infrastructure) into what is known as Next-Generation infrastructure. Transformation is the process of a service provider’s network components, end-user facilities, and business processes being converted or modified to achieve the competitive advantages provided by newer technologies. Internet Protocol (IP)-based technology enables this transition. The demolition of the legacy setup can or may not be followed by the implementation of new infrastructure, facilities, and business processes.
As service providers want to cut operating costs while still adding new end-user offerings, getting rid of the legacy network is a must. Carriers replace outdated legacy network components and infrastructure with more powerful technology in these transition scenarios. Carriers will be required to migrate customers and commercial services from legacy networks to new networks as part of these transformation projects.

Organizations that are undergoing digital transformation are more likely to have moved workloads to the cloud. As a result, coping with the problems and threats associated with legacy network architectures designed for a pre-cloud age becomes a challenge. Hubert da Costa investigates the problem and proposes a solution.
More companies are embracing a digital-first strategy in today’s modern business world to help them stay on top in terms of innovation, productivity, and growth. Legacy network technologies, on the other hand, are incapable of providing the performance and agility necessary for a digital-first strategy. Organizations that do not embrace digital transformation risk being left behind by their rivals and consumers. Despite the obstacles, companies must engage in their own digital transformation, and software-defined wide area networking technology, or SD-WAN, is proving to be a viable solution.
The adoption of mobility, Big Data, social media, cloud, and the Internet of Things (IoT), all of which are stretching conventional business perimeters to the network edge and beyond, has been the impetus for today’s IT connectivity challenge. In this scenario, the traditional method of connecting remote sites and new applications through virtual private networks (VPNs) has become much less effective and expensive. The practice of simply adding more VPNs to safe distributed enterprise locations has become increasingly complicated and cost-prohibitive as new applications are introduced. As a result, traditional VPN technology has become more vulnerable to emerging security threats, making it less attractive in highly distributed environments.

Simplifing legacy network transformation to all-ip

For the past few years, SDN-based networking creativity has been a constant highlight. For its global visibility and programmability to configure, orchestrate, automate, and control the network, the SDN (Software Defined Network) nomenclature is a possible modernization of conventional networking society. The separation of the control and data planes has made network administration much easier. Furthermore, it has opened up the possibility of openness from simple management functions to rapid provisioning when it comes to deployment.
Unlike conventional networks, which have a vertical paradigm, SDN networks have a horizontal paradigm with an open interface that provides a global view of the entire network from a logically centralized stage. Any change can be regulated or changed from a single location if it occurs. The key concept behind SDN is to separate the control plane from the data plane. The control plane determines how to manage traffic, while the data plane forwards traffic based on the control plane’s decision. We have a Northbound API and a Southbound API in SDN. The controller and higher application programs communicate through the northbound API. The network administrator may add the required modules/functions for network management to these application programs. Multitenancy, virtualization, and load balancing are only a few examples. The current functions of the Northbound API are primarily for network automation. It is a programmable abstraction of the network’s internal functionalities, allowing improvements to be made faster than provisioning the network with new capabilities and components. The controller communicates with data plane devices using any Southbound enabled protocol in the Southbound API.
