fyi Yakov. ****** The following is a COPY ***************************** Received: from merit.edu by watson.ibm.com (IBM VM SMTP V2R3) with TCP; Thu, 21 Apr 94 12:17:01 EDT Received: from localhost (jyy@localhost) by merit.edu (8.6.8.1/merit-1.0) with SMTP id MAA14094; Thu, 21 Apr 1994 12:13:50 -0400 Message-Id: <199404211613.MAA14094(a)merit.edu> To: bgpd(a)merit.edu cc: jyy(a)merit.edu Subject: CIDR, proxy-aggr or Die? Date: Thu, 21 Apr 1994 12:13:49 -0400 From: Jessica Yu <jyy(a)merit.edu> Hi, Below is the NSF/ANSNET routing table size growth history data which Merit has been collecting. It shows that, on average, every two weeks there are ~500 more routes added to the routing table between 4/93 - 3/94 and the average growth is 4%. Note, this is prior to people start to withdraw more specific routes. It also shows that during the first half of month 4/94, the routing table increased by 333 routes instead of 857 during the previous two-week period. This shows the effect of CIDR. So what's the point? 1. Since we start to withdraw more specific routes around Apr. 1st.'94, it helped reduce the growth of the routing table by more than a half (4.1% vs 1.7%) 2. The routing table grows faster since the beginning of this year than last year, the average increase of two-week period since 1/94 - 3/94 is 776 routes or 4.57%. Everyone can do a calculation and figure out when his/her routers will run out of memory. 3. It still adds 333 more routes during the two-week period when we start to withdraw more specific routes. We need to do more CIDR. If we withdraw more or the same amount of routes added, we win. That requires us - When advertise new routes, advertise aggregates not aggregatable specific routes. Do more aggregation on existing specific routes and withdraw them. So again: ASs who do BGP4 already, please advertise aggregates and remove your more specific routes. ASs who do not do BGP4 yet, please either run BGP4 and do aggregation or delegate your neighbor ASs to proxy aggregate your routes. It used to be: CIDR, default or die! It is now: CIDR, proxy-aggr or die! --jessica P.S. The reason this set of data is shown in bi-weekly format is that we want to see the effect of CIDR since 4/94. Since 4/15, there are a lot more withdrawn happened so it should be interesting to see the data at the end of this month.

Re: 20402 routing entries
by Walt Haas 21 Apr '94

It seems to me that this entire discussion is based on the premise that renumbering is extremely slow, difficult, expensive and disruptive. This belief is probably justified given current technology. Our Chemistry department reported that they renumbered 20 workstations, and it was a week before anybody involved got any useful work done. One shudders to think what this means if extrapolated to the global Internet. However, if we could develop a technology which could make renumbering of a network (ie. a company, university or similar-sized unit) fast and efficient, this premise would break down and it would no longer be unreasonable to consider renumbering the organization when switching providers. Suppose, for example that Domain Names were sacred but a daemon could somehow touch every machine in a certain domain simultaneously and give it a new number, while simultaneously updating the routing tables that pointed into that domain? No, I don't have an RFC written, sorry, it's just an idea. -- Walt -------

I'm sure that we will all eventually do CIDR/BGP4 and maybe even slow the growth of routing tables to a managable level. By this time we will all have 500MB routers..... Now with talk of global renumbering and a Utopian world of CIDR, what do we lose? I was never optimistic of how CIDR would work in a real operational redundant topology like the current internet. In this scenario, it is a big win to be able to have fine grain control of routing down to the organizational level. What does this mean? Well you can develop a routing strategies which take into account many diverse exit points from your AS. You can develop routing strategies based on high end users, low-end users, route the east coast here, the west coast there. You name it. You can't do this by routing large blocks of networks around. Pure CIDR'ists will say that you should divy up your blocks and assign addresses accordingly. Well... how many people who run networks have stayed with the exact same routing strategy with zero changes for more than 6 months? New connections and connectivity happen. The internet is an ever changing place. My CIDR allocation today will not be good for my routing strategy 2 months from now. As Andrew said, we are not fortune tellers... So, In a totally static topology, CIDR "the movie" and global renumbering will work. I wouldn't bet on static topology... Mark

Some time in the next few weeks we will begin supporting an expanded syntax, where the AS may be followed by an optional NSS peer number in parentheses. Eventually, this syntax will be used to replace most or all of the current Fake ASs. This change will affect *all* places that the announcement lists are reported: all whois queries, all network reports, this "NWG" report, and the Auto-NACR. If you have code which parses these announcement lists, please be aware that that code may need modifications soon. CIDR Reports: There is a new "whois" option to list aggregates in the PRDB: whois -h prdb.merit.edu listaggs will produce a listing of the currently registered aggregates. There is also a new report on "nestings" of PRDB-registered aggregates with their more specific routes: nets.non-classful. Anyone considering configuring an aggregate into the PRDB (and you all should be!) is encouraged to pre-check that aggregate by typing the command: whois -h prdb.merit.edu 'aggchk <agg>' (where "<agg>" is the aggregate description). This command will list all of the other entries in the PRDB that are more specific routes of <agg>, as well as any aggregates all ready configured that contain <agg>. The output includes the AUP and announcement lists of each of the nets printed, with discrepancies flagged. This is the same program that we use for sanity-checking the NACRs that you submit. The archived discussion list "db-disc(a)merit.edu" exists for discussion of PRDB issues.

Merit Routing Registry
by epg＠merit.edu 18 Apr '94

18 Apr '94

Merit is happy to announce the Merit Routing Registry. Whereas Merit designed and manages the PRDB (Policy Routing Data Base) for the NSFNET service, RIPE pioneered a policy routing registry for the European community. The RIPE Routing Registry is based on the document, RIPE-81. With RIPE's collaboration, Merit installed RIPE-81 software and then extended the policy descriptions in order to realize more complex policies. The Merit Routing Registry will be a companion registry to the RIPE Routing Registry and is intended to serve the community that is not served by RIPE. This is a new service and we consider ourselves still in the beta phase. Registrations may be basic policy descriptions defined in RIPE-81 or complex routing policy descriptions defined in the Extended Policy Syntax document by Chen, Gerich, Joncheray, and Yu. The Extended Policy Syntax document may be found on rrdb.merit.edu:pub/meritrr/policy_syntax.txt. Documentation for using the MeritRR can be found on rrdb.merit.edu:pub/meritrr. Merit and RIPE anticipate that the combined registries will provide a more comprehensive picture of the routing interactions in the Internet. We are working together to allow the two registries to appear like one virtual registry to the various tools that are developed. We welcome your comments on all aspects of this project. For more information, please respond to rradmin(a)rrdb.merit.edu. Elise Gerich, Merit Network, Inc. Daniel Karrenberg, RIPE NCC

You've been selling the CIDR drugs, your responsibility was to have come up with one. I think the community needs to have a solution, i can't come up with a unilateral one, and it will take a LONG time to sell a multilateral one. But we've been working on them for some number of months. Hint, think about buying back network numbers. General principal of the US Constitution is that if you take something you give some relief. (I'm not saying this is uniuque to the US btw).

Ref: Your note of Fri, 15 Apr 1994 10:52:00 -0400 Henry, >This assumes alot, including customers that don't switch providers >and inject more specific routes (this is happening already). No, I assumed that most (but NOT all) of the customers who switch providers would renumber. I can further weaken this assumption by allowing aggregation above the immediate provider level (you can do this with CIDR). >You're also assuming that we have a mechanism for aggregating >routes for folks who choose not to (or can't, for some reason). That is not so far-fetched assumption. Proxy aggregation is likely to happen, whether some folks like it or not. >CIDR only buys us a *little* time.. Remember there is "CIDR movie", but there is also "CIDR book". You need to consider both... Yakov.

a modest proposal
by Walt Haas 18 Apr '94

18 Apr '94

The idea below seemed to make sense last night after a couple of margaritas at the Rio Grande Cafe, let's see if anybody else thinks it will fly. If this isn't the right place to discuss it let me know, I will forward it appropriately. -- Walt ======= PROPOSAL FOR A NEW NAME/ADDRESS PARADIGM FOR THE INTERNET April 16, 1994 Walter O. Haas University of Utah Salt Lake City, UT 84112 <haas(a)ski.utah.edu> 1. Internet names are the property of the user, not the network service provider. An Internet name has much the same legal status as a registered trademark, and is suited to appear in advertising and other literature completely independently of the Internet service provider currently employed by the user. Internet names will be issued by a central authority directly to the user. Optionally, a network service provider may handle the necessary paperwork for a user to obtain a name, but this does not give the said provider any right or interest in the name issued and the provider must not attempt to mislead the user to the effect that it has such a right. 2. Internet addresses consist of a <provider-part> and a <customer-part>. The <provider-part> belongs to the Internet service provider, and is used by Internet routers to switch traffic to agreed points of that service provider's network. The <customer-part> belongs to the customer. A complete Internet address is of the form <provider-part>.<customer-part>. If the customer decides to obtain services from a different provider, the customer shall adopt addresses using the <provider-part> of the desired provider. It shall be possible for a customer host to be multi-homed to two addresses with different <provider-parts>, either temporarily or permanently. The <provider-part> consists of two areas: a <provider-id> which identifies the organization providing service, followed by a <provider-specified> part which tells that provider's network how to route to the customer network. Thus a complete Internet address can be specified as <provider-id>.<provider-specified>.<customer-part> Providers are assigned a <provider-id> by a global authority, but may choose their <provider-specified> part according to their internal criteria, which may include (but are not limited to) technology, geography, business plan, and perceived customer desires. All providers are required to forward traffic to any of the globally-defined <provider-id> values, but are not required to process any portion of the Internet address beyond that (except their own). There shall however be a defined upper limit on the size of the <provider-specified> and <customer-part>. 3. Each user host shall be configured with its Internet name. Upon booting, the host shall send a Name-to-Address Request (NARQ) packet to a defined broadcast address. The NARQ packet will contain the host's name. A server will respond with a Name-to-Address Reply (NARP) packet containing the Internet address of that host. 4. If the customer decides to change Internet service providers, it will need to assign a new <provider-part> corresponding to the new Internet address of the new service provider to each host. This will be done by giving the new <provider-part> to the customer's nameserver, which will then send appropriate NARP packets to the relevant network hosts which will then each have two Internet addresses. This operation obviously needs appropriate security. When the customer's network has acquired the new set of addresses and the old service provider is no longer in use, then the customer's nameserver can send an appropriate Name-to-Address Invalid (NANA) packet to each host to invalidate that address from its configuration. This operation also needs to be secure. -------

About three years ago we renumbered all of the state Universities in Michigan (except Michigan State U). It was a lot of work and I wouldn't want to do it very often, but the whole business went much better than I expected. The key is good planning. Another key is getting people to use domain names rather than IP addresses whenever possible. We had signs up saying "Names good, numbers bad!". -Jeff Ogden Merit/MichNet
