我输入“google.com”DNS解析对应于输入名称的IP地址,然后在传输层使用3次握手(我正在考虑http)创建通信端点并发送数据格式为TPDU到网络层。现在,在网络层,它将该数据包重定向到默认路由器,该默认路由器然后检查网络前缀并决定将数据包转发到何处。有关网络层和传输层工作的说明
1)where the actual data is converted into packets.I mean where the packets gets generated,if answer is at the client ,then who performs this job.
2)where the address of default router is specified,how the packet gets directed from one machine to default router.
3) I know TCP receives data in the form of stream of bytes.(So I am confused between terminology of TPDU).
Thanks in advance.
