ARP : The ARP (Address Resolution Protocol) protocol /procedure for mapping IP network addresses to an address of a physical hardware device, otherwise known as a MAC address.The link layer is t he group of communication methods that manages the transmission of data between physical devices and a network. The ICMP protocol is not concerned with exchanging data, rather its purpose is to en sure whether the data is reaching the intended destination. ICMP : ICMP (Internet Control Message Protocol) protocol is a network protocol that allows network devices, like routers, to help diagnose communication issues.IP : The IP (Internet Protocol) protoc ol, along with the TCP protocol, is a set of requirements that define how data is sent over the Internet.The internet layer, also called the network layer, is tasked with sending and reassembling network p ackets in the most efficient way using network addresses/IP address to send packets to their destination. UDP : The UDP (User Datagram Protocol) protocol allows applications to send messages, called datagrams, to other hosts on a network.The TCP protocol manages the process of assembling and sending (and sometimes re-sending, if necessary) the data packets and ensures that all packets have been send and delivered. For example, when a server sends back a file due to a client request, the HTTP layer will communicate with the transport layer to set up and send the file requested. TCP : The TCP (Transport Control Protocol) protocol is used to ensure transmissions between a client and server are secure and that the entire communication was processed.The transport layer handles the transmission of data, which also includes the TCP and UDP protocols, and ensuring data is sent and received correctly and promptly.
SIP is also used in conjunction with other protocols, such as SD P (Session Description Protocol), UDP, TCP, and TLS to carry session data and media.
SIP is the protocol that is used to enable and de ploy VoIP (Voic e Over Internet Protocol) services.
The IMAP protocol can sync messages across multiple devices. POP : The POP (Post Office Protocol) protocol is like IMAP, but the difference is that the POP protocol allows the user to receive messages from an email server, but the message is then deleted from the email server.Unlike SMTP, you cannot use the IMAP protocol to send email messages. IMAP : The IMAP (Internet Message Access Protocol) protocol is used to manage and receive messages from an email server.TLS ( Transport Layer Security) was introduced in its place to provide a secure way to communicate over a network. TLS/ SSL : The SSL ( Secure Sockets Layer) protocol was officially deprecated in 201 5.SMTP : The SMTP ( Simple Mail Transfer Protocol) protocol is used to send a nd rec ei ve emails between senders and receivers on a network.FTP : The FTP ( File Transfer Protocol) protocol is used to transfer files between a browser and a server wi thin a computer network.DNS : The DNS ( Domain Name System) protocol converts domain names to human-readable IP addresses for browser so resources can be loaded.It is the layer w here the interaction between person and computer occurs an d information can be sent back and forth from a server via a client/browser and interpreted and displayed for users. The application la t er specifies the protocols and interface methods used by clients and servers. Some of the other more common Internet protocols you many have come across include the following: The HTTP protocol is the backbone of the Internet used for communication and sending data between clients and servers. The HTTP protocol, which is technically part of the application layer within the Internet Protocol suite, is just one many protocol s under the IP suite. These requests all follow the HTTP (Hypertext Transfer Protocol) standard.
HTTP ERROR 418 UNUSED FULL
Click on the RFC reference documents in the list below for full details of the status codes.Įvery time a user visits a website, they are making a request from their browser/client to a server that responds with the resources they requested. Using Filters you can remove results with specific status codes from your tasks, alerts, and reports. These status codes are maintained by the Internet Assigned Numbers Authority (IANA) and the most current list of codes can be found here. These HTTP status codes, or network error codes, will appear in the results of a monitoring session as well as in alert notifications. Every time a task is run on a monitored device, the target server returns HTTP status codes to indicate the status of the response from the server.
