VPN basic concepts
VPN
Function: establishes a secure private network on an insecure public network for encrypted data transmission.
VPN and tunneling Technology
Tunnel protocols include
Passenger Protocol: encapsulated protocol, such as PPP and SLIP
Encapsulation protocols: establish, maintain, and disconnect tunnels, such as L2TP and IPSec
Bearer Protocol: the protocol that carries encapsulated data packets, such as IP
The topological structure refers to the physical or logical interconnection between computing units in a distributed system. The Topological Structure between nodes has always been an important basis for determining the system type. Currently, centralized and hierarchical topologies are widely used in interconnected networks. Interne is the world's largest non-centralized interconnected network, however, some network application systems established in 1990s are completely centralized, and many w
With the rapid development of P2P applications, the discovery technology, as the core issue of P2P applications, not only follows the logic of the technology itself, but also is profoundly influenced by the development trend and Demand Trend of some technologies. -As mentioned above, the DHT discovery technology is fully built on the basis of a deterministic topology structure, which demonstrates guidance o

OpenVPN is a software package used to create a VPC encrypted channel. It implements a two-or three-tier tunnel-based VPN. It was first written by James Yonan. OpenVPN allows the created VPN to use a public key, digital certificate, or user name/password for authentication. It uses a large number of SSLv3/TLSv1 protocol libraries in the OpenSSL encryption library.
Currently,

A common problem of P2P is how to efficiently locate a node. That is to say, how can a node efficiently know which node in the network contains the data it is looking for? For example:
There are three typical solutions to this problem.
Napster: uses a central server to receive all queries, and the server tells where to download the required data. The problem is that a single point of failure on the
