–fibre or cable and why?<\/p>\n

–is it Sonet or ATM; and why<\/p>\n

–What are the encoding technologies?
—ADSL, HFC and why??<\/p>\n

How to improve performance?
–Areas of Concerns: Buffering, encoding standards, high speed storage, algorithms that require less seek time, networks that provide less jitter and high speed, any caching or proxy will help or not, using p2p will improve performance or not<\/p>\n
