Re: [LARTC] HTB has 2 bucket?
thank you for your reply i'm doubt about before i known , there have two bucket. my assumption is ... first bucket for keep token sending with rate guarantee and this bucket size are same as burst size and in every minute ... number of token will create at least rate token but max with burst size but after true is ... HTB have 2 bucket My assumption are true for htb technique to handle "burst traffic"??? first bucket size for keep token is burst size for handle when burst traffic coming. every minute, number of token will create at least rate token for guarantee bandwidth but max with burst sizeand support burst (i'm not sure if max token are burst size, at first time to handle burst traffic. htb will use all token in bucket but when next second??? Bucket are empty? so max bucket size may be bigger than burst size??) when class use banwidth exceed rate, class will borrow banwidth from parent class so class will use ctoken that keep in another bucket(bucket for keeping ctoken and ctoken are come from only parent' token) i don't understand when burst traffic coming how htb choose between2 bucket are use? i see picture from http://linux-ip.net/traffic-control/htb-class.png don't understand. why must checking in ctoken before token Is it true? because burst traffic will use token more than token in first Bucket. so it will skip to check ctoken. Is it max enough, it will use all token in first+bucket and ctoken in secoond Bucket because for theory htb to handle burst traffic, htb allow to sending with burst rate until average rate equal to burst threadhold, htb will change rate to rate guarantee, if use only token in first bucket to handle burst traffic i think this mechanismwill use token and among sending with burst rate if number of available token are qual or more than little bit num of rate token for guarantee bandwidth, it will change to sending with rate guarantee? (i'm not sure for my assumtion, If my assumption are wrong. can you tell me the trueth?) advise me please, thank you - Original Message From: Martin A.

[LARTC] HTB has 2 bucket?
in HTB use 2 bucket for manage 2 rate??? first bucket - keep token for sending with rate second bucket - keep ctoken for sending with ceil rate Is it true?? may be i'm misunderstand about token/bucket thoery___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
