SD-WAN Development Discussion: SD-WAN combined wit

As software-defined wide area networks (SD-WANs) become mainstream, it will help drive the flexibility and adaptability of the blockchain. Combining the blockchain with SD-WAN reduces audit and regulatory risk by accelerating processing times, reducing transaction costs, and documenting detailed packet flows validated by each node of each transaction.
Although the prospects are good, there are still some problems to be solved. Such as the private blockchain and public blockchain problems, etc., but the SD-WAN use cases are beginning to be realized.
Legacy networks, which are static, expensive to deploy, and require very long deployment cycles, are unacceptable to networks using blockchain technology. To succeed, the blockchain transport layer requires a low-cost public Internet link that can be deployed reliably and must always be available to all users.
With support for real-time application performance and predictable service assurance, SD-WAN is likely to play an important role in future blockchain deployments. As SD-WAN becomes more prominent, blockchain technology is evolving and using blockchain architecture as a transport layer makes it easy to manage real-time system events and network activity using a centralized SD-WAN controller.
Since blockchain records permanently verifiable transactions and is good at protecting records, SD-WAN controllers can leverage blockchain to manage network and system events. In fact, Hyperledger, an open-source orchestration tool developed to promote cross-industry blockchain technology, has begun to evaluate how to incorporate blockchain into software-defined networking (SDN) components.
Since each block is an instantaneous transaction or event record, the entire block chain must be visible to all stakeholders across multiple networks. And each new record must be validated by each node, and since no one or record can break the blockchain it is almost impossible to disrupt the network traffic. The main advantage of the blockchain is that the ledger is basically synchronous.
SD-WAN has in some ways dropped its own modules, especially SD-WAN in the case of measurement delay and congestion or End-User Quality of Experience (QoE) standards on a data-by-packet basis. Since blockchain also needs to dynamically add new blocks to the existing blockchain, the ability of SD-WAN to intelligently provide flexible bandwidth based on the number and size of the blockchains is also key to increasing the price and performance of blockchain transactions .
While Bitcoin is currently the most popular blockchain application, other real-time applications such as Enterprise Resource Accounting (ERP) or Customer Relationship Management (CRM) may also migrate to the blockchain because of the distributed nature of these features To provide users with the best quality of experience.
