- MINUTES
-
- The Stanford meeting began with a review of the objectives discussed at the
- April meeting. The next topic was a discussion of information required by a
- host to participate in Internet communications:
-
-
- o IP address
-
- o Subnet properties
-
- -- Subnet mask
-
- -- MTU
-
- -- Broadcast address
-
- o Default gateway
-
- o DNS server
-
- o Domain name of host
-
- o High-level services
-
- -- Boot services
-
- -- Other gateways
-
- -- Local network topology
-
-
- Having agreed on the list of configuration information, the group developed
- a list of mechanisms required to distribute and maintain host
- configurations:
-
-
-
- 3
- o IP address discovery
-
- o IP address allocation
- o Subnet properties discovery
-
-
- o Gateway discovery
-
- o Gateway reconfiguration
-
- o DNS server discovery
-
- o Domain name allocation
-
- o DNS update/name, IP address registration
-
- o High-level resource discovery
-
-
- These mechanisms can be loosely grouped into two categories: discovery
- mechanisms, which transmit configuration information to a host, and
- allocation mechanisms, which determine host-specific information. For
- example, the mechanism used to transmit an IP address to a host can be
- entirely independent of the mechanism used to select that IP address.
-
- Several members of the group described details of existing configuration
- mechanisms (both at the meeting and immediately afterward, through the
- host-config@rutgers.edu mailing list). There are several existing protocols
- of interest to this group:
-
-
- o ICMP
-
- o BOOTP
-
- o Athena NIP (Schiller and Rosenstein, MIT)
-
- o Dynamic IP Address Assignment (Morgan, Stanford)
-
- o DRARP (Brownell, Sun)
-
-
- At the next meeting, we will discuss an Internet Draft that summarizes the
- conclusions reached at the Stanford meeting.
