From page 61...
... DETAILED RECOMMENDATIONS In the following recommendations the committee provides details about actions that should be taken to implement the basic recommendations. Most of the recommendations involve actions that require the DOD to take the lead role, with occasional support from the NBS Institute for Computer Sciences and Technology.
From page 62...
... This will include dual protocol operation for some gateways, relay hosts, service hosts, and terminal concentrators. A secondary purpose of the test system described in detailed recommendation 3 should be to aid in development of this transition support equipment.
From page 63...
... (7~. The NBS Institute for Computer Sciences and Technology should maintain close liaison with DOD to ensure that DOD needs for new protocols and modifications to existing standards are effectively represented to appropriate standards bodies.
From page 64...
... Such collaboration could help ensure that future protocol standards will be developed in a single, coordinated process that results in a single standard accommodating both DOD, other federal agencies, and commercial needs.
From page 65...
... When more frequent interaction is anticipated and better service is needed, major service hosts should support both old and new protocol sets concurrently so they can provide service directly without requiring the use of relays. Such service hosts include widely used time-sharing machines, file servers, and special servers such as Network Information Centers, Network Operations Centers, and Administrator Machines (providing mailboxes of network administrators, for example)
From page 66...
... To limit the amount of change attempted at one time, the DOD IP may be retained and used under TP-4. Alternatively, if ISO IP development status seems to warrant it, ISO IP may be installed along with TP-4.
From page 67...
... introduction of the ISO IP to replace DOD IP may commence. In addition to simply replacing one IP with the other in hosts and gateways, this will require modification of the gateways to perform ICMP and GGP on top of the ISO IP.
From page 68...
... There were significant performance probe ems that required careful analysis and parameter tuning after the transition. These were unavoidable because no service host had been stressed prior to the switchover, with a full user load over a long time period using the new protocols.
