- TCP의 handshaking 같은 연결 설정이 없다 - DNS, NFS, SNMP, RIP 등 사용. 소켓 통신 과정 - 서버 : 소켓을 생성, 주소 할당, 데이터를 송수신 - 클라이언트 : 소켓 생성 후 데이터 수신. UDP는 TCP와 달리 데이터의 수신에 대한 책임을 지지 않는다. UDP is very simple, while TCP is more sophisticated, it also sends ACKs of all the packets that have been received to confirm that the data has been delivered, but since the majority of the traffic that is encapsulated within the VPN packets it already using TCP, this additional verification is not needed. Generally, because UDP is so simple OpenVPN UDP vs TCP - When to use them? TCP (Transmission When the TCP VPN protocol is used there is "guaranteed delivery." This is due largely in part to a method called "flow control." Flow control determines when data needs to be re-sent and stops t 16/09/2018 · Both TCP and UDP are protocols used for sending bits of data — known as packets — over the Internet. The main difference between TCP and UDP is the way these packets are delivered. Escolhendo entre UDP e TCP. O TCP oferece melhor confiabilidade e velocidades mais lentas. O UDP oferece velocidades mais rápidas e menos confiabilidade para conexões de Internet mais lentas. Quando você usa pela primeira vez um serviço de VPN que utiliza o OpenVPN, tente o UDP.

So which to choose? Below I’m testing out NordVPN, which gives me the option to select TCP or UDP protocols. Here’s a brief overview of both protocols:

Flexible Connectivity. Connect via IKEv2, OpenVPN UDP, TCP or Stealth on a wide range of ports. Get Windscribe. What is 

TCP is more reliable, so you may think that TCP is the best option, but there are times when UDP might be preferred. There is an option within the OpenVPN application that allows selection of a TCP-based connection, however if you find it becomes necessary to use TCP - we recommend using SoftEther or L2TP (L2TP is a TCP-based client offering flawless connection for mobile devices in particular). If the VPN uses TCP, then your own TCP connections will use IP packets sent through the VPN, so you end up paying the TCP overhead twice. An UDP-based VPN thus has the potential for slightly better performance. On the other hand, the cryptographic protection of the VPN requires some state management, which may be harder for the VPN
