UDP and TCP are two protocols that are responsible for determining how data is exchanged on the internet. Since both are built on the IP protocol, they do share similarities.

It provides an unreliable datagram connection between applications. Data is transmitted link by link; there is no end-to-end connection. The service provides no guarantees. Data can be lost or duplicated, and datagrams can arrive out of order. The trade-offs between TCP and UDP (regardless of VPN usage) is always the same: You sacrifice speed for reliability as UDP is connectionless and the server sending the data theoretically (depending on the implementation) doesn't care if it reaches the destination or not. This is fine in things like Internet gaming where each packet might be a movement by a user, but in things like encryption J'en déduis que NC limite le traffic tcp upload a 5 MBs mais pas le traffic udp. Le serveur vers lequel j'utilisais une session NNTP etait localisé au pays-bas et c'est ce traffic qui etait limité a 6.3 MO/s en TCP et passait sans probleme a 10 MO/s en UDP via le tunnel. Moralité, il semble que l'usage du vpn soit interressante.
