Novell IPX Routing Service
General Addressing Considerations
Bindery Services: manage name resolution, accounting, and security.
Diagnostic Services: retrieve software setup and status.
Directory Services: access a distributed file system directory.
File Services: access remote files.
Message Services: deliver datagrams to IPX nodes.
Message Handling Service (MHS): handle electronic mail file and
exchange formats and procedures
Queue Management Services (QMS): handle control queues of
incoming requests, including processing and printer queues.
Synchronization Services: coordinate tasks among multiple users,
including file and record locking and semaphores.
Transaction Tracking System (TTS): ensure the integrity of file
operations in the case of system failures.
General Addressing Considerations
An IPX packet header contains a source network address field and a
destination network address field. The network address is composed of
three fields, as shown in figure 1. The network number uniquely identifies a
network in the internetwork. A host number uniquely identifies a single host.
The socket number uniquely identifies a socket within the operating system
of a host. A socket is the address of a higher-level protocol—Routing
Information Protocol (RIP) for example—that is using the services of IPX.
The source and destination network addresses uniquely define the
communicating sockets in the entire internetwork.
When IPXWAN is used, the IW2 header is contained within the data portion
shown in figure 1.
