Networking development takes on voice quality, SD-WAN security
The old telephone systems set a high bar for engineering its network for call quality. Then came the internet, and with it, new technologies like VoIP and other applications that need to always operate with high reliability and quality standards. In this edition of Network Evolution, we look at what's driving VoIP networking development and what users expect when it comes to voice and video quality.
And equally as important to networking development is security, network managers who are deploying software-defined wide area networks (SD-WANs) say. Vendors are beginning to offer products that build security into an overall SD-WAN provisioning platform, and users are looking for features that manage firewalls while not degrading performance. In this issue we study several use cases for SD-WAN technology.
Finally, Cisco has stepped up its certification and training programs in an effort to build its reputation as a software provider. For professionals working with Cisco's Digital Network Architecture, the new certifications offer more education on how to manage and automate networks through a central software console instead of reprogramming hardware individually.
