The existing methods for RTT-aware conditioner work well when the congestion level is low.
然而现有的RTT感知流量调节机制在网络拥塞程度较轻时非常有效。
To mitigate the bias of TCP congestion mechanisms to short RTT flows, the existing methods cannot work well when network congestion level is high due to the over protecting to long RTT flows.
为了缓解TCP拥塞控制机制对于往返时间(rtt)较小流的偏向问题，现有方法在网络拥塞程度严重时由于对rtt较大流的过分保护而不能有效地工作。
As congestion grows beyond this level, traffic slows down and congestion sets in.
如果流量超过这一水平，通行将减缓，公路将开始出现拥堵情况。
Knowing simply that traffic congestion is getting worse, for example, helps you make high level decisions to focus on road maintenance or public transportation.
例如，发现交通拥堵情况变坏，有助于高层决策部门关注于道路维护和公共交通。
There are even discussions at national level, e.g. in the UK and Germany, on extending congestion charging to all roads.
在某些国家，如英国和德国，正在讨论在所有道路上收取拥堵费的问题。
The problem is that the airlines would fix a profit-maximizing minimum price, and it probably would exceed the price necessary to reduce congestion to the optimal level.
不过这样做的问题就是，航空公司会定一个利润最优化的最低价格，而这个价格很有可能会超过使飞机拥挤程度减小到理想水平所必须的价格。
However, the resulting average queue length is quite sensitive to the level of congestion and to the parameter Settings of RED.
然而这种算法使得平均队列长度对于网络的拥塞水平以及RED参数设置非常敏感。
The costs of congestion might justify the overall level of fuel duty, although it is a blunt instrument for dealing with the problem, they say.
尽管这不是处理问题的最佳手段，但交通堵塞的成本可能会调节燃油税的整体水平。
There are even discussions at national level, e. g. in the UK and Germany, on extending congestion charging to all roads.
在某些国家，如英国和德国，正在讨论在所有道路上收取拥堵费的问题。
Watch for congestion to form at the 38% or 62% level. Then use a simple breakout or breakdown strategy when price moves past it.
观察38%或者62%位置形成的密集区，当价格穿越该回调位时，可以使用简单的突破或回测策略进行交易。
