How does TCP/IP work? TCP/IP uses aclient-server communication model, meaning that one device – typically the user – requests information or sends updates to another computer, the server. The server then responds to the request, offering services like sending a webpage or updating a databas...
What Are the Concepts Related to PCEP? How Does PCEP Work? PCEP Applications Why Do We Need PCEP? Path computationcanbe a complex task to complete, especially on large multi-domain networks. In some scenarios, it requires a special computation component to be deployed on the controller, and ...
What Problems Does PPPoE Solve? PPP stands for a point-to-point protocol. With PPP, one node can access only one other specified node. PPP is located at the second layer in the Open Systems Interconnection (OSI) reference model and at the data link layer in the TCP/IP model. It is ...
How does TCP work? TCP works by using a “three-way handshake” — a three-step process that forms a connection between a device and a server. The completion of the three-step process establishes the non-stop connection, starts the transfer of data packets across the internet, delivers them...
Since these first iterations, the development and definition of firewalls have continued to evolve, and the history of firewall technology is still being written. What does a firewall do? A firewall filters data entering your network. It analyzes that data by checking the sender’s address, th...
The User Datagram Protocol, orUDP, is another widely used transport protocol. It is faster than TCP, but it is also less reliable. UDP does not make sure all packets are delivered and in order, and it does not establish a connection before beginning or receiving transmissions. ...
Although it may not be possible to prevent a data breach from happening, it is possible to protect against online identity theft by using a VPN. Through tunneling, a VPN encrypts your data so that no one else, including fraudsters, can see it, thus securing your information even when you...
One drawback of a persistent connection is that if one client does not close the connection after receiving all its required data, other clients will be unable to access the resources needed to keep the connection open on the server. This can affect resource and server availability for these ...
