Hello, we are going to talk about the SD-WAN
Software-Defined Wide Area Network (SD-WAN) is a transformative technology that simplifies the control and management of IT infrastructure by developing a virtual WAN architecture that connects all users to their applications.
SD-WAN features simplified branch office connectivity, increased reliability, improved application performance, and increased network flexibility. SD-WAN reduces total costs by enabling better use of resources and a more automated WAN and branch office architecture, which is necessary to deliver modern IT business initiatives.
SD-WAN combines various network circuits, such as broadband, DIA, and LTE. These circuits can be added to existing MPLS to create a hybrid network, or they can be an alternative to MPLS using wired and wireless connections all over the Internet.
Characteristics
1. Superimposed network
SD-WAN creates an overlay network independent of the WAN transport and can replace existing branch office routers, simplifying the WAN infrastructure. SD-WAN offers better control and management, providing control at the application layer of application service policies, to ensure optimal application performance.
2. Knowledge of the application
A key component of SD-WAN is application knowledge. SD-WAN understands individual applications and their SLA requirements and translates them into policies that the network must adhere to. This enables active monitoring of the network and application experience that ensures optimal distribution of traffic and quality of experience, whether on-premises, in a private or public cloud, or in a SaaS environment.
3. Policy-based framework
SD-WAN also provides an automated policy-based framework that propagates from unified control and management, all from a one-stop-shop interface. Visibility is enhanced, allowing IT to gain insight into applications, devices, users, and networks to help ensure business goals and objectives are met. This simplifies the ability of IT to define, control and modify business requirements across its branch offices, datacentres and cloud / SaaS.
Thanks
