The comment by Dave brought me back to check what a change of a factor of 10 does to the throughput in TFRC. RFC 3448 gives in section 8 the following alternative format of the throughput equation (which is directly responsible for the alllowed sending rate X): s X = -------- R * f(p) This shows that the dependence is reciprocal. Thus using an RTT which differs by a factor of 10 to account for in-stack processing results an a throughput reduction of factor 10. In other words, 90 Mbits/sec becomes 9 Mbits/sec. - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
