此时意味着服务器响应长度超过512 bytes字节,但是udp只能返回512字节。 此时,客户端就需要使用TCP重发原来的DNS查询请求。 2. DNS的主辅名字服务器在同步时使用TCP协议,辅名字服务器一般每小时向主名字服务器发起查询, 看主服务器是否有新的记录变动,如果有, 将执行一次区域传送,区域传送就是使用TCP协议。
After upgrading to 24h2, the ability to connect to RDP via UDP disappeared everywhere. However, on previous versions everything is fine, configuring policies and substituting mstsc.exe etc. does not solve the problem. This problem itself was still in…

Why Error "Add rule to chip failed" or Is Error "Adding rule failed" Is Frequently Reported When an ACL Rule Contains a TCP or UDP Port Range? The number of applied rules that contain "range" has reached or exceeded the maximum. The S series cards support 16 TCP or UDP port ranges ...
DTLS衍生自TLS,并且保留了UDP无序的语义,但是它还是从TLS继承了很多复杂的东西,本质上,DTLS也是封装应用数据的,这些应用基于UDP。循着这个思路,如果我们可以将IP数据报看作是一个基于UDP的应用数据,那么就可以用DTLS封装它了,能吗?当然能!UDP本身就是IP的第四层镜像,只是多了一个多路复用机制。使用DTLS封装IP数据...
WebRTC / ICE has an internal process to determine which one is best to be used using a priority system (RFC5245) . Usually, this means direct host connections will be tried first, then stun, then turn. It will also prefer udp over tcp. The detail of the process is left to the inter...
UDP traffic vs TCP streamsUDP has unfairly developed a reputation of being unreliable. This is perhaps due to the fact that the protocol is connectionless, does not retransmit lost data, and has a much simpler protocol overhead than its transport-layer cousin. While these statements are true, ...
RDP Shortpath. UDP shortpath is a Azure Virtual Desktop feature that DevBox uses (DevBox utilizes Azure Virtual Desktop infrastructure). With UDP shortpath enabled, DevBox will attempt to establish UDP based transport (instead of TCP) if possible, to achieve better connection reliability...
iWARP:基于以太网传输层 TCP 协议,利用 TCP 达到可靠传输。相比 RoCE, 在大型组网的情况下,iWARP 的大量 TCP 连接会占用大量的内存资源(RoCE 的 UDP 连接不需要),对系统规格要求更高。可以使用普通的以太网交换机, 但需要专门支持 iWARP 的网卡。 在AI 算力建设浪潮中,IB 是早期局部最优解,RoCE 是更广泛最优...
