Response to RFC 567 - cross country network bandwidth

4. Furthermore, if the demand for remote echoing ever exceeds network capacity, the TIPs and Hosts can simply buffer 2 characters per message, doubling the effective bandwidth of the network. Of course, dozens of characters can be packed into a single message with nearly proportional increases in effective bandwidth, given the size of the overhead. This buffering happens automatically and incrementally with increasing load as the natural consequence of slowed responses.
