IPX/SPX

SCO IPX/SPX provides a means of connecting SCO systems and NetWare networks. The following protocols are supported:

• ``IPX''

• ``SPX''

• ``SAP''

• ``RIP''

• ``NVT''

IPX

IPX™ is a datagram service protocol which allows individual packets to be sent to and received from user processes. IPX is a connectionless service; it does not support the concept of a connection or reliable delivery. However, guaranteed services like SPX have been built on top of IPX. IPX is used in situations where a guaranteed service is not required or where an occasional lost packet is not critical.

For more information, see ``Internetwork Packet Exchange (IPX)''.

SPX

SPX is a connection-based, reliable, sequenced transport protocol which provides both guaranteed packet delivery and flow control. Packets are received in order by the destination endpoint and the speed at which the sending and receiving processes manipulate packets is regulated.

SAP

SAP (Service Advertising Protocol) is a method by which networks can advertise available network services. SAP allows service nodes (such as file servers, print servers, and application servers) to advertise their services and addresses. The SAP daemon uses the SAP protocol to advertise these services.

For more information, see ``Service Advertising Protocol (SAP)''

RIP

The Routing Information Protocol (RIP) facilitates the exchange of routing information on a NetWare network. For more information, see ``Routing Information Protocol (RIP)''.

NVT

The Novell Virtual Terminal (NVT) protocol is a guaranteed-delivery, connection-oriented protocol. It is built on top of IPX and uses IPX to send packets and receive positive acknowledgments of packet delivery.

IPX/SPX end-user commands

Several IPX/SPX commands, described in detail on their manual pages, provide end users with networking capabilities:
