- Which means that the filtering functionality currently available
- in routers gets pushed out to end nodes and is carried out
- at call setup? I'm not sure that I'm comfortable with this
- sort of arrangement. Take a hypothetical situation where,
- as a part of organizational policy--possibly for budgetary
- reasons--users should be denied access to interactive video
- communication outside of a given administrative domain but
- that other services, some of which might include non-interactive
- video/audio retrieval from a subset of information providers,
- should be allowed. With TCP, we have "well known" port numbers
- that services are offered over and can be used to filter traffic
- related to these services. Thus, "domain level" administration
- and security is made possible. If ATM forces the management
- of this type of security to individual hosts, I'm not sure
- that administrators will adopt seamless LAN/WAN integration.
- I see this as something that needs work before a truely
- integrated LAN/WAN ATM solution will be acceptable for
- many organizations.
