What is SD-WAN appliance?
An SD-WAN uses a centralized control function to securely and intelligently direct traffic across the WAN and directly to trusted SaaS and IaaS providers. This increases application performance and delivers a high-quality user experience, which increases business productivity and agility and reduces IT costs.
SD-WAN is a wide-area network with a virtualized overlay, abstracting the software from the hardware. Its key features include network abstraction, WAN virtualization, policy-driven centralized management, and elastic traffic management.
Cisco vBond
When a router boots up for the first time in an unconfigured state, vBond is responsible for onboarding the device into the SD-WAN fabric. It is the job of vBond to understand how the network is constructed and then share that information amongst other components.
The most common use cases are branch offices, campus networks, metro Ethernet services and enterprises that need quality of service (QoS) for real-time applications. For the most part, networking vendors believe MPLS will be around for a long time and that SD-WAN won't totally eliminate the need for it.
There are three basic types of SD-WAN deployments: Internet-based SD-WANs, Telco and MSP Managed Service SD-WANs, and SD-WAN as-a-Service.
vBond – initiates the bring up process of every vEdge device, at the first step it creates secure tunnel with vEdge and informs vSmart and vManage about its parameters like for instance ip address. It has to be fully connected with every device.
SD-WAN solutions must have security mechanisms at startup (or initial installation) at the branch office. Bidirectional safe authentication is needed to cover the remote SD-WAN terminator to the central point and back again. There are many different products aimed at resolving this risk and allowing ZTP.
vBond The vBond is part of the orchestration and zero touch deployment of SD-WAN, a vBond tells the vEdge which vSmart will be responsible for its configuration and policies.
Cisco SD-WAN offers a centralized policy (network-wide scope) and the localized policy (single-device scope). There are two localized policy types: Localized control policy. Localized data policy.
13. Can the Cisco SD-WAN Solution provide optimization for IaaS and SaaS platforms like AWS, Microsoft Azure and Office 365, Google, Salesforce.com, Cisco Webex, etc? It can.
What is SD-WAN silverpeak?
Silver Peak Unity is the premier software-defined WAN (SD-WAN) architecture for today's enterprise. Unity is a virtual WAN overlay that enables customers to deploy hybrid or all-broadband WANs using multiple types of connectivity, including MPLS, cable, DSL, LTE, etc.
