Chapter 3. Requirements Protogate Freeway Requirements Specification (SRS)
3.8.36. GEN006380 - NIS/NIS+ Implemented Under UDP
Summary The system must not use UDP for NIS/NIS+.
Notes Implementing NIS or NIS+ under UDP may make the system more susceptible to a Denial of
Service attack and does not provide the same quality of service as TCP.
3.9. Environment Requirements
The Freeway software is intended to be installed and run only on a Protogate Freeway system. See any of the
Freeway 3xxx Hardware Installation Guide documents for details about a specific Freeway model -- for example,
Freeway 3412 Hardware Installation Guide (DC-900-2018). The Freeway software does not have any other
environmental requirements -- though the Freeway is usually connected to an IP network and to one or more
serial-link WAN connections, the Freeway software must be able to run without any connections.
3.10. Computer Resource Requirements
This section describes the Freeway’s computer resource requirements. The Freeway software always runs on a
Protogate Freeway chassis, so it must never require more resources than any Freeway chassis can provide.
3.10.1. Computer Hardware Requirements
The Freeway software is intended to be installed and run only on a Protogate Freeway system. See any of the
Freeway Hardware Installation Guide documents for details about a specific Freeway model -- for example, Freeway
3412 Hardware Installation Guide (DC-900-2018).
3.10.2. Computer Software Requirements
The Freeway software does not use or require any other software; it is completely self-contained and complete.
3.10.3. Computer Communications Requirements
Depending on the intended use, a Freeway may be connected to one or more serial-link data communication
connections, one or more 10baseT/UTP, 100baseTX, 1000baseSx, or 1000baseTx Ethernet IP network connections,
and/or a serial link console terminal. However, none of these connections is required, and a Freeway could be
configured in such a way that none of these connections is used or necessary.
