RE: Blast from the past
Title: RE: Blast from the past Ah, dual stacks, a time tested transition strategy. But there was some Application Layer Gateway cruft (ALG) although not at the level of sophistication and beauty of a NAT ... From RFC 801: Because all hosts can not be converted to TCP simultaneously, and some will implement only IP/TCP, it will be necessary to provide temporarily for communication between NCP-only hosts and TCP-only hosts. To do this certain hosts which implement both NCP and IP/TCP will be designated as relay hosts. These relay hosts will support Telnet, FTP, and Mail services on both NCP and TCP. These relay services will be provided beginning in November 1981, and will be fully in place in January 1982. Initially there will be many NCP-only hosts and a few TCP-only hosts, and the load on the relay hosts will be relatively light. As time goes by, and the conversion progresses, there will be more TCP capable hosts, and fewer NCP-only hosts, plus new TCP-only hosts. But, presumably most hosts that are now NCP-only will implement IP/TCP in addition to their NCP and become "dual protocol" hosts. So, while the load on the relay hosts will rise, it will not be a substantial portion of the total traffic.

RE: How many routers an OSPF or IS-IS area can have
Keep in mind that the limitations of OSPF can actually be the total number of subnetworks rather than the total number of routers. Cisco recommends that you not have an OSPF area with more than 90-100 routers. Additionally it is Cisco's recommendation that you not have more than 200 subnetworks per an area. Again .. these are recommendations and the network topology can have a dramatic effect on what are stable numbers for other networks. -matt luallen mcse, ccie, cissp argonne national laboratory -Original Message- From: Bora Akyol [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 25, 2001 1:23 PM To: Jerome Etienne Cc: David Wang; '[EMAIL PROTECTED]'; '[EMAIL PROTECTED]' Subject: Re: How many routers an OSPF or IS-IS area can have I think the max numbers are somewhat conservative.

Announcing mailing list for Internet Personal Appliances discussion, proposed BoF
The Internet Area ADs felt that it would be useful to bring to your attention a mailing list ([EMAIL PROTECTED]), archive and web site for discussion of Internet Personal Appliances (formerly known as Networked Appliances) research. To subscribe to the list, e-mail to [EMAIL PROTECTED] with 'subscribe' in the Subject field. An archive of past mails is available at the Internet Personal Appliances research web page: http://www.argreenhouse.com/iapp/ A growing number of people are interested in contributing to the area of Internet Personal Appliances. An informal BoF was held at the most recent IETF meeting to discuss issues and work areas appropriate to the IETF. There over 130 subscribers today to the appliances mailing list. We intend to hold a formal BoF on the subject at the next IETF, and wish to broaden the discussion and input to include all of IETF. Please subscribe to the mailing list if you are interested in participating. Many thanks. Simon
