System Administration Guide: IP Services

Application Layer

The application layer defines standard Internet services and network applications that anyone can use. These services work with the transport layer to send and receive data. Many application layer protocols exist. The following list shows examples of application layer protocols:

Standard TCP/IP Services

UNIX “r” Commands

The UNIX “r” commands enable users to issue commands on their local machines that run on the remote host. These commands include the following:

Instructions for using these commands are in the rcp(1), rlogin(1), and rsh(1) man pages.

Name Services

Oracle Solaris provides the following name services:

Directory Service

Oracle Solaris supports LDAP (Lightweight Directory Access Protocol) in conjunction with the Sun Open Net Environment (Sun ONE) Directory Server, as well as other LDAP directory servers. The distinction between a name service and a directory service is in the differing extent of functionality. A directory service provides the same functionality of a naming service, but provides additional functionalities as well. See System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP).

File Services

The NFS application layer protocol provides file services for Oracle Solaris. You can find complete information about the NFS service in System Administration Guide: Network Services.

Network Administration

The Simple Network Management Protocol (SNMP) enables you to view the layout of your network and the status of key machines. SNMP also enables you to obtain complex network statistics from software that is based on a graphical user interface (GUI). Many companies offer network management packages that implement SNMP.

Routing Protocols

The Routing Information Protocol (RIP) and the Router Discovery Server Protocol (RDISC) are two available routing protocols for TCP/IP networks. For complete lists of available routing protocols for Oracle Solaris 10, refer to Table 5–1 and Table 5–2.
