SRv6 VPN

A VPN is a virtual private communications network built over the public network of an Internet Service Provider (ISP). Considered to be both private and virtual, logically isolated VPNs can be created over an underlying transport network. Sites of the same VPN are securely connected across and within domains, while VPNs are isolated from each other. In view of this, VPNs can be used to implement interconnection within an enterprise, for example, to interconnect the headquarters with branches.

VPNs can allow employees to securely access a corporate intranet while travelling outside the office. Similarly, VPNs can securely connect geographically separated offices of an organization, creating one cohesive network. VPN technology is also used by individual Internet users to secure their wireless transactions, to circumvent geographical restrictions and censorship, and to connect to proxy servers for the purpose of protecting personal identity and location.

A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Therefore, applications running across a VPN may benefit from the functionality, security and management of the private network (Mason, 2002).
Development of building thermal environment emulator to evaluate the performance of the HVAC system operation
Published in Journal of Building Performance Simulation, 2019
A VPN is a private network that is virtually established on a public network. Using a VPN, a server and client can communicate as if they were on the same local network. Although a port for a VPN must be opened, because this is a communication technology commonly used in a wide variety of fields, there will likely to be fewer barriers to doing so than for opening ports for BBMD communication. Based on this advantage, the proposed emulator system implements remote communication via VPN using the network configuration shown in Figure 4, in which a connection is established by installing VPN software to the server and client and is used to perform BACnet communication. The past operational data of the emulator and a list of BACnet device port numbers are downloadable from a Web server.
COVID-19 and Its Impacts on Managing Information Systems
Published in Information Systems Management, 2020
Most organizations are obviously concerned with security. It’s probably safe to say that organizations have taken to using corporate Virtual Private Networks (VPNs) to safeguard information as best as possible. However, are these corporate VPNs designed to handle thousands of employees working at the same time? Although VPNs can provide encryption capabilities, public Internet may be an unreliable mechanism that could translate into slow connections, lost connections, and overall lower quality, especially if connections are global in nature.
