The Country also stood for an experience of the world confined to the shires of England, as opposed to the sophistication bred of the Grand Tour through France and Italy; for the maintenance of open hospitality for all, as opposed to the offering of luxurious private dinner parties in the City; for a highly conservative taste in Jacobethan architecture, as opposed the new-fangled classicism of Inigo Jones; for a highly conservative taste in portrait-painting, as opposed to the courtly continental innovations of Van Dyke; for a highly conservative taste in clothes, as opposed to the dizzily changing fashions of the beau monde at Court.

Spurious timeout is very harmful to TCP. Two kinds of approaches were proposed to mitigate this problem, conservative approach and aggressive approach. In conservative approach, a conservative RTO, minRTO, is used. When RTO estimate form RTT is less than minRTO, it is set to minRTO. This makes RTO become predictable and may be exploited by attackers.

在TCP里，错误的逾期会造成相当大的伤害，而已经存在有两种类的方法来减轻这个问题，我们称他们为保守措施与积进措施，在保守措施里有用到一个保守重送逾期值(RTO， Retransmission Timeout) minRTO，当根据RTT 所估算出来的RTO小於 minRTO 时，RTO就会被设为minRTO，这样的做法会让RTO变成是可预测的，进而可能被攻击者利用。
