1、 启动Python的IDLE工具,创建名为服务端.py的文件,输入相应代码内容。 2、 导入socket模块后,创建一个socket对象。第一个参数指定IP类型,AF_INET表示使用IPv4地址;第二个参数定义传输协议,SOCK_DGRAM代表UDP方式,若使用SOCK_STREAM则为TCP方式,后者是默认的传输 ...
Abstract: Almost all DNS queries that traverse Internet are transported via UDP in self-contained small packages. Therefore, with no restriction of packet ordering, the intuition would say that adding ...
UDP(用户数据报协议)是一种无连接的网络协议,它提供快速但不可靠的数据传输方式。由于UDP的报文大小限制,单个数据报的最大有效载荷通常限制在64KB以内。因此,在实际应用中,如果我们需要通过UDP传输超过64KB的数据,就必须进行特殊处理。本文将介绍 ...
Pull requests help you collaborate on code with other people. As pull requests are created, they’ll appear here in a searchable and filterable list. To get started, you should create a pull request.
In this project , you will emulate the operation of a link layer and network layer protocol in a small computer network. You will start several nodes so that they can ...
Computers have used socketed processors for most of the PC’s lifespan, with a few notable exceptions like Intel’s cartridge-based Pentium II and III aside. These sockets change every few processor ...
本文分享了Linux内核网络数据包发送在UDP协议层的处理,主要分析了 udp_sendmsg 和 udp_send_skb 函数,并分享了UDP层的数据统计和监控以及socket发送队列大小的调优。 这个函数定义在 net/ipv4/udp.c,函数很长,分段来看。 在变量声明和基本错误检查之后, udp_sendmsg 所 ...
