Svuda u svetu je flat uglavnom asimetričan. Najveći broj korisnika od servisa interneta koristi samo web i mail, a koliki bandwidth može biti potreban za slanje http zahteva? ;)
Da samo podsetim da su i 56k protokoli (k56flex, x2, v90) asimetrični. DL je u idealnim uslovima na 56k, ali UL je i dalje 33k6 (ili beše čak 28k8, ne sećam se više)

Citat:
With DOCSIS 1.0 data transmission is asymmetric, with most of the bandwidth reserved for the
downstream link from the CMTS to the cable modem. This enabled the operators to quickly deploy
applications like Web browsing and e-mail while efficiently utilizing available bandwidth. CableLabs
began interoperability certification in June of 1998 and the first cable modems and CMTS platforms
were DOCSIS-certified in the spring of 1999. Vendors scrambled to gain DOCSIS certification, and the
race to build out broadband infrastructure accelerated worldwide.
U dokumentu takođe piše da je prema DOCSIS 1.X standardu upstream ograničen na 10.24Mbps, za downstream nisam siguran, moj modem (Motorola SB4200e) može da izvuče maksimalno 51Mbps.
