BrowseMan Posted November 7, 2003 Share Posted November 7, 2003 Аз съм от същатата мрежа 217.10.249. При мен такива пакети не пристигат, което май вече стана ясно .Единствено получавам такива пакети от програмата за чат в локалната мрежа. Така че положението никак не е розово.

No dori i togava, za da e vsichko OK, mrejata triabva da routira vsichki multicast paketi, t.e. da igrae roliata na MBONE Takova neshto az ne sam zabeliazal. Edinstvenata "zaiavka", koiato dava winamp plugin-a e malak multicast paket na port UDP+1, kadeto UDP e porta na osnovnia multicast stream. V tova paketche ima malko informacia za tova kak se priema stream-a i atributite na station-a. Tova obache ne e zadaljitelno i e svarrzano osnovno s drugia product - LiveCaster (sashtite deto sa pravili plugina za winampa) Zinf klienta obache ne izprashta nikakvi "zaiavki" a samo si slusha choveka, no tova ne go pravi po-losh RTP klient, dori naprotiv - toi se darji mnogo po-dobre.

Player-a izprashta zaqkva za prisuedinqvane kum grupata na multicast-a i 4ak sled tova zapo4va polu4avaneto na paketite. Vse pak nqma logika tova vseki da gi polu4ava po default vsi4ki tiq paketi. Taka shte se natovari s dosta i samata mreja. P.S. Eto i failovete ot Ethereal. Slojil sum filter "ip multicast" Files I dvata faila sa capture za gore dolu edin i sushto period.

Samia klient (bil toi audio ili video) ne sazdava takav paket problema e, che tozhno niakade tam se kasat neshtata Inache za natovarvaneto pak ne e savsem taka - nali e postoianen multicast stream, koito ne zavisi ot broia na klientite v daden segment.

Nali tochno zatova e celta na multicast-a - da ne vliza v broikata na trafika, prednaznachen za konkretnia user.
