Sepam Ethernet GuideThe Internet protocol suiteMain application protocolsThe Internet protocol suite comprisesnumerous application protocols. We onlymention here those that can be used withSepam devices.The client-server modelMany application protocols are based on the client-server model. This modeldescribes the relationship of cooperating programs in an application.The server component provides a function or service to one or many clients, whichinitiate requests for such services. The server permanently listens to these incomingrequests. Often clients and servers are located on separate hardware, but both clientand server can also reside in the same system.ICMPThe Internet Control Message Protocol (ICMP) is used to exchange servicemessages. It is not, strictly speaking, an application protocol (it really belongs to thenetwork layer), however its best known use case is at the application level throughthe ping command. This command sends ICMP echo messages to test if givennodes are reachable.FTPThe File Transfer Protocol (FTP) enables the transfer of files in both directionsbetween a client and a server. It is mainly used for loading CID configuration files intothe devices.HTTPThe Hyper Text Transfer Protocol is the protocol used between a web browser and aweb server. Sepam interfaces have an embedded website/web server.SNMPThe Simple Network Management Protocol can be used to access management datacontained in devices. This data is arranged as normalized structures called ModuleInformation Bases (MIBs).Sepam interfaces provide an SNMP agent and several MIBs.SNTPThe Simple Network Time Protocol is used to distribute time among network devices.Sepam interfaces act as an SNTP client.12 SEPED310018EN - 10/2010
