VoIP: Lessons from Early Adopters Experts say VoIP isn't a magic wand that will solve all of an organization's communications challenges right out of the box. Learn why VoIP may not produce expected savings and productivity gains, and other lessons from early adopters. Click Here to Watch Today, TAPs are available for permanent deployment in the data center, helping enterprises manage complex infrastructures. Leveraging a permanent out-of-band network access platform (permanent TAP), users are able to maintain 24/7 network visibility and real-time management benefits without affecting network performance. SPAN (mirrored switch ports) and other network deployment methods once held their own, but the increasing data load placed on these tools is severely affecting enterprise infrastructure management. Permanent TAP solutions avoid bandwidth pitfalls by establishing an out-of-band platform to deploy any critical network device. With a physical TAP integrated in a desired network segment, the out-of-band device has uninterrupted, hardware-level visibility into the tapped network traffic, without having to compete for access and, most importantly, without affecting network flow. The detailed visibility that permanent TAPs provide is ideal for enterprise monitoring and management, giving TAP-attached devices the ability to identify errors and events — including link-layer events — within the network.
