SDWAN: Chapter-1: Introduction to SDWAN
SD-WAN Definition A Software-defined Wide Area Network (SD-WAN) is a virtual WAN architecture that allows enterprises to leverage any combination of transport services – including ILL, MPLS, LTE & broadband internet services – to securely connect users to applications hosted within the Data Centers. It is a virtual WAN architecture that gives enterprises the flexibility to take maximum advantage of any combination of transport services for securely connecting users to applications. The top five advantages of SD-WAN technology include improved performance, boosting security, lowering complexity, enabling cloud usage, and reduced cost. So, in nutshell, A software-defined wide area network (SD-WAN) is a network that is abstracted from its hardware, creating a virtualized network overlay as a Hub-Spoke topology Need of SD-WAN Clients are using the traditional MPLS network to cope up with their application connectivity within the DC (Active-Passive or Active-Acti...
