Thus my > high degree of personal interest in what it implements... ;-) After having much grief with two Netblazer (a PN-2 and a ST), running a load-balanced SLIP link over two 28.8k modems. Netblazer's use a very simple algorithm, if a output buffer on the first interface exceeds a certain level, try the next interface (on a packet by packet basis). The maximum buffer levels are configurable. So under low load, a Netblazer will only use the first line. Netblazer's can be configured to bring up additional lines if load exceeds a certain limit. Tom
