Request frame
请求帧───Request frame
To make future communications more efficient, the IP address and hardware address mapping of the source host is also included in the request frame.───为了使下一步的通讯更有效,发送端主机的IP地址和硬件地址的映象也包含在请求帧中。
If the request meets these prerequisites, you can embed the portlet content into a window frame.───如果请求满足这些先决条件,则可以将Portlet内容嵌入到窗口框架中。
strategy that works in many cases is to abort a request and resend it if you don't get a response in a reasonable time frame.───在这种情况下,如果在合理的时间段内没有得到响应,不妨采用一种有效策略:中止请求然后重新发送。
If the mapping is not in cache, ARP builds an ARP request frame for the destination hosts hardware address.───如果这一映象在高速缓存中找不到,地址解析协议就会产生一个ARP请求帧以获取目标主机硬件地址。
If the mapping is not in cache, ARPARP request frame for the destination hosts hardware address.
To make future communications more efficient, the IP address and hardware address mapping of the source host is also included in the request frame.
