VoIP relies on isochronous design to ensure time-sensitive delivery of voice data, requiring output timing to match input timing. Time-division multiplexing, TCP protocol, and VLAN technology are not utilized in this context, as VoIP primarily uses UDP for voice transmission. The focus is on delivering a quality voice experience, distinguishing it from general network congestion solutions.

VoIP uses which of the following because network congestion can be s.pdf
- 1. VoIP uses which of the following because network congestion can be such a critical problem? A. Time-division multiplexing B. TCP protocol C. VLANs technology D. Isochronous design Solution D. VoIP is very time sensitive and, as such, should be based on an isochronous design. This means that the entire system must be engineered to deliver output with exactly the same timing as the input. FireWire is another example of a device that contains an isochronous interface. Answer A is incorrect because VoIP does not use time-division multiplexing. Answer B is incorrect because VoIP uses UDP for the voice portion of the call, not TCP. Some implementations of VoIP can use TCP for setup and call control. Answer C is incorrect because VLANs are not used for timing and delay problems, but are used to separate the VoIP from general traffic to make it more secure from sniffing.
