QoS

Neděle Leden 22 07:24:05 CET 2006

Pokud jsem si alespon otevrel SPA2100 manual (staci hledat na netu, je to 
obsahle PDF, anglicky), tak port forwarding tam bezpochyby je. QoS 
samozrejme bude resen s ohledem na VoIP (tj. priorizace packetu hlasovych 
pred vsim ostatnim) a o to jde, vyresis to snadno bez nejakeho stresu. Cena 
vč. DPH a dopravy: 3 000,00 Kč.

Akorat musis zahodit stavajici adapter a router, ale mas jistotu, ze sipura 
je na voip nejlepsi.

Timhle treba take zjistits nejake info nastavenych parametrech (podledni 
string nahrad svym rozhranim do internetu):

tc qdisc show dev ppp0

Tady je skript na ten uploud, dokazal by to nekdo rozsirit o download 
(vyhrazeni linky v pripadne aktivity na voip napr.?):

# Kapacita uplinku u vasi linky v kbit/s - cokoliv mensiho, nez 
nominal.kapacita ISP,

allowed to borrow from another
