nato ale budes potrebovat aby huby maly 100Mb uplink

to je aj nieje pravda. zalezi od toho pripojenia k serveru.
ak tam ostane 10Mb tak sa odlahci len o prenos medzi stanicamy ktory
vecsinou nebiva moc velky. takze zisk bude minimalny.

mi sme v minulej praci maly spravenu siet asi takto

                +-----+
server---100Mb--+ 100 +-----HUB/switch z 100Mb uplinkom--10Mb klienti
server---100Mb--+ MB  +-----HUB/switch z 100Mb uplinkom--10Mb klienti
server---100Mb--+ swi +-----HUB/switch z 100Mb uplinkom--10Mb klienti
server---100Mb--+ tch +-----HUB/switch z 100Mb uplinkom--10Mb klienti
                +-----+

a nikdy neboly zaznamenane problemy z priepustnostou 99% klientou slo

First they came for the Communists,
     and I didn't speak up,
         because I wasn't a Communist.
Then they came for the Jews,
     and I didn't speak up,
         because I wasn't a Jew.
Then they came for the Catholics,
     and I didn't speak up,
         because I was a Protestant.
Then they came for me,
     and by that time there was no one
         left to speak up for me.
