Routing Information Protocol (RIP)
On the client, NCP is called the NetWare shell or, more commonly, the requestor. Using
NCP, the client sends a request to the NetWare file server. The server processes the
request and sends a reply to the client. The client can have only one request outstanding
at a time; it must wait for a response from the file server before sending another request.
NonStop™ IPX/SPX provides the requestor portion of NCP, which is used exclusively
by the LAN Print Spooler for NetWare process to send print jobs to print queues on the
NetWare file server.

, describes NCP
in more detail.
Routing Information Protocol (RIP)
RIP maintains routing tables that are used by IPX to find the fastest route to transmit
data on an internetwork. RIP is needed when the destination address of an IPX packet
contains a network field value different from that of the source address.
Appendix A, Protocol Interfaces and Services for NonStop™ IPX/SPX
, describes RIP in
more detail.
Service Advertising Protocol (SAP)
SAP allows service nodes such as file, print, and database servers to register their
services and addresses in SAP tables maintained by each server. The registration is done
through SAP broadcasts every 60 seconds. If the broadcast of a specific service stops, all
other servers purge the service from their SAP tables within approximately three
minutes.
