TCP tends to use packet loss as the signal of congestion and oscillates its flow rate between some lower rate and this loss-triggering rate.
说到拥塞,我们的测试环境目前有不少于19个不同的2.4GHz网络正在广播。
Speaking of congestion, our test surroundings presently has a minimum of 19 different 2.4GHz networks being broadcasted.
在拥塞避免阶段,只要未收到重复确认,拥塞窗口则在每次往返时间内线性增加一个MSS大小。
In congestion avoidance state, as long as non-duplicate ACKs are received the congestion window is additively increased by one MSS every round-trip time.
如果网络变得拥塞(超负荷),窗口大小减小,从而减慢数据包的传输。
If the network becomes congested- overloaded- then the window size will be reduced, slowing packet transmission.
拥塞窗口是发送方使用的流量控制,而通告窗口则是接收方使用的流量控制。
The congestion window is flow control imposed by the sender, while the advertised window is flow control imposed by the receiver.
如果4G网络变得不稳定、拥塞或不可用,连接将自动切换到3G(HSPA/WCDMA)。
If the 4G network becomes unstable, congested or unavailable, the connection will automatically switch to 3G(HSPA/WCDMA).
慢启动初始启动时设置拥塞窗口值(cwnd)为1、2、4或10个MSS。
Slow-start begins initially with a congestion window size(cwnd) of 1, 2 or 10.
某些扫描会造成网络拥塞,然而Ping扫描在网络中最多只会产生两个包。
Some scans can flood the network with packets, but the Ping Scan only puts, at most, two packets on the network.
同时,5GHz速度更快且拥塞较少,但难以穿透物体和墙壁。
Meanwhile, 5GHz is faster and less congested, but it has difficulty penetrating objects and walls.
但是,如果你在使用一个专用的点对点连接,那么你会希望禁用它,因为那不太可能遇到拥塞。
But if you're using a dedicated point-to-point connection, you will want to disable that since it's unlikely to suffer from congestion.
一个TCP发送方如何感知从它到目的地之间路径上存在拥塞.
Let's next consider how a TCP sender perceives that there is congestion on the path between itself and the destination.
原则上,亲核试剂通过碳阳离子中间体逐步置换离去基团使得能够构建高度拥塞的碳中心。
In principle, stepwise displacement of a leaving group by a nucleophile via a carbocationic intermediate enables the construction of highly congested carbon centres.
网络上太多的广播和超量的流量负载可能导致网络拥塞:网络性能降低。
Too many broadcasts and a heavy traffic load on a network can result in congestion: a slowdown in the network performance.
