For example, RIP sends updated routing tables out every 30 seconds, while OSPF sends updates only when necessary and makes updates to the particular part of the table where the change occurred. OSPF was developed as a more streamlined and scalable alternative to RIP. OSPF is similar to and supports Routing Information Protocol - which directs traffic based on the number of hops it must take along a route - and it has also replaced RIP in many networks. It also updates routing tables - a set of rules that control where packets travel - and alerts routers of changes to the routing table or network when a change occurs. OSPF opens the shortest, or quickest, path first for packets. IP aims to send packets on the quickest route possible, which OSPF is designed to accomplish. OSPF works with IP in sending packets to their destinations. What is SMTP (Simple Mail Transfer Protocol)?.What is DHCP (Dynamic Host Configuration Protocol)?.

Want to learn more about common network protocols?Ĭheck out these video definitions from TechTarget's YouTube channel, Eye on Tech, to get more insight into these common network protocols. This diagram shows how HTTP provides users with access to the various components of a website's domain. This provides more security to users and can prevent common cybersecurity threats, such as man-in-the-middle attacks. HTTPS can encrypt a user's HTTP requests and webpages.

HTTP connects to the domain's server and requests the site's HTML, which is the code that structures and displays the page's design.Īnother form of HTTP is HTTPS, which stands for HTTP over Secure Sockets Layer or HTTP Secure. When a user enters a website domain and aims to access it, HTTP provides the access. Like FTP, HTTP is a file sharing protocol that runs over TCP/IP, although HTTP primarily works over web browsers and is commonly recognizable for most users. However, FTP is a common network protocol for more private file sharing, such as in banking. Clients request files through the command channel and receive access to download, edit and copy the file, among other actions, through the data channel.įTP has grown less popular as most systems began to use HTTP for file sharing. FTP runs over TCP/IP - a suite of communications protocols - and requires a command channel and a data channel to communicate and exchange files, respectively.

FTP is a client-server protocol, with which a client requests a file and the server supplies it. DHCP handshakes occur when a device initially connects to a network.įile Transfer Protocol. The device establishes a connection the server receives it and provides available IP addresses the device requests an IP address and the server confirms it to complete the process. When a device connects to a network, a DHCP handshake takes place, where the device and DHCP server communicate. Whenever a device joins a network with a DHCP server for the first time, DHCP automatically assigns it a new IP address and continues to do so each time a device moves locations on the network. DHCP assigns IP addresses to network endpoints so they can communicate with other network endpoints over IP. DNS also includes the DNS protocol, which is within the IP suite and details the specifications DNS uses to translate and communicate.ĭNS is important because it can quickly provide users with information, as well as access to remote hosts and resources across the internet.ĭynamic Host Configuration Protocol. Servers can cache DNS data, which is required to access the websites. DNS translates the domain name into IP addresses, and these translations are included within the DNS. DNS is a database that includes a website's domain name, which people use to access the website, and its corresponding IP addresses, which devices use to locate the website.
