The problem with end-to-end protocols

The problem is that remediation measures (e.g., reducing the rate, changing the CODEC, adding FEC, etc.) may, in fact, make the conditions worse. Often this results in applications not being able to utilize the available capacity of the underlying networks. We will show in the next blog how the typical response of TCP with a packet loss of less than half of one percent will reduce the effective throughput of a link by over 95%. That means a 25 megabits-per-second broadband connection that is perfectly capable of supporting video, voice, and file transfers suddenly become effectively a 1.25 megabits-per-second link barely capable of voice.

Since almost every user now accesses their apps and services through a form of wireless network, there will almost always be some packet loss. This makes the ability to overcome this loss and stop the severe impact on the end-user experience paramount for organizations with remote workers.
