Networking Concepts
Network Environment Design Considerations
use a
FDDI networks also offer greater distances than LAN, Token Ring,
If you need to connect nodes that are geographically distant (for example, HP e3000s located in different cities) you might choose to connect them via a dial link. For NS dial links, you can use the
Finally, if you need to use satellite transmission because of the large geographical distance between nodes, or if you need to have access to other nodes on a public or private X.25 network, you might wish to use the DTC/X.25 iX Network Link.
Special Cases
The following sections describe certain design requirements for special situations, such as shared dial links, personal computers, and using
Shared Dial Links
Shared dial links have two limitations that must be considered when designing a network. First, a shared dial link cannot be used as an intermediate link in a
LAN, Token Ring, FDDI,
Applicable SYSGEN Parameters
VT terminals are not physical devices, instead they are virtual devices created dynamically at remote logon, header entries are created for the maximum number of VT terminals at system boot time. The exact number of head entries created for VT terminals will depend on the value of MAXDYNIO (which is configurable in SYSGEN).
The exact number of remote sessions which can be supported on a given system will depend on the exact mix of jobs and sessions (remote and local, active and inactive) on that system.
