Asymetrical Routing
by Jayme Cox 22 Aug '97

22 Aug '97

I've been investigating a problem we seem to be having with asymetrical routing. We have connections from both UUnet and Digex and are taking full routes from both. We have had some complaints that people are unable to access our network and most of these cases appear to prefer the Digex route. However, our outgoing paths to those same networks prefer the UUnet route. My question is: How bad is this? Is it terminaly bad or simply not so great? Out of order TCP packets are bad, but can simply be reassembled. Timout should not be a problem as both links are >= 6 Mbits. Thanks, --Jayme

The Cidr Report
by Tony Bates 22 Aug '97

22 Aug '97

This is an auto-generated mail on Fri Aug 22 12:00:00 PDT 1997 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

I certainly accept that, so with respect to your assertion that EUnet was "kicked out" of Ebone 6-7 years ago I decided to check on three obvious primary sources, viz. Frode, Kees Neggers and Glenn Kowack. The first choice was obviously the easiest. Frode (unsurprisingly) was surprised at your version of history. I was too, since it varied with what I remember seeing at the time (remember I have some UUNET history too :-) ). He also said that Ebone would be very happy to welcome EUnet back into the fold if the departure was due to some misunderstanding several years ago. I shall ask the other two at leisure today or tomorrow in email. BTW, since there are other people reading this who would make good primary sources, I welcome any historical retrospectives by private email. > Among other things, you seem to overlook Which other things, out of curiosity?

Wow, this is a rat's nest. :) Um, my ICM memories are that in the first place Ebone was initially principally an academic consortium, but that as commercial traffic began appearing, NSF funding began disappearing. I believe (Steve Goldstein can correct me if I'm wrong) that Ebone generally acquired capacity on fractions of lines the NSF did not pay for. There is some fuzziness about the RENATER lines, and one could take several readings on the NORDUNET capacity over the past couple of years, but in any event, I think you will find that any indirect subsidy really didn't amount to all that much (Dr Goldstein's pockets are only so deep) and probably did go to the benefit of the NSF's community of interest, and in particular during the period when Ebone was still a consortium rather than the hybrid Association/Incorporation in place now. There is no question that Rick was a pioneer in investing in the international growth of the commercial Internet, and that alot of the proliferation of the Internet in Europe is due in some measure to him. > As you are probably aware, we have been on very friendly terms with > Ebone for several years now.

Simon Leinen <simon(a)limmat.switch.ch> writes: > There are many of these small links over the pond. One of the reasons there are so many trans-oceanic links between Europe and North America is that the cost of a trans-oceanic full-circuit is almost infinitely cheaper than inter-country circuits at PNO tariffs, thanks to inexpensive U.S. half-circuits. This is changing, largely due to E.U. telecomms liberalization. > I'd be interested > in whether (and if so: how) different providers manage to save costs > by sharing fast transcontinental lines among themselves. Hm, I wonder if I can put enough value into answering this question to have people forgive me for talking about my (European) employer on an ostensibly North American mailing list? :-) Ebone is a customer-owned trans-continental backbone provider that functions as a buyers' cooperative with respect to inter-country (and in some cases intra-country) capacity. The not-marketing-person designed web page describing this can be found at http://www.ebone.net/structure/objectives.html This largely works in part because of the origins of Ebone and the people who have worked with it since then, and because Ebone focuses principally on large ISPs. That leads to the assumption that customers aggregate enough traffic that they will use all the capacity they pay for at all times, which also leads to Ebone's no-overbooking design, and consequently to Ebone's rather large cost-based prices relative to its competitors which target vastly different markets, or do massive loss-leading, or do massive cross-subsidy, or all three. One way of looking at the Ebone backbone is as a large TDM network, much as one could build with ATM and CBR VCs, only without the drawbacks of ATM or a big VC mesh (and with the drawbacks of a complicated router-based network). There are of course several other pan-European providers such as Unisource's UBN, BT's CIP, UUNET, EUNET, Compuserve, Global -1, and IBM Advantis, each of which appears to function much like their counterparts or analogues in the U.S.A. This, however, is not exactly "line sharing" per se. Finally, there may be people sharing lines bilaterally or multilaterally among a small group of organizations. Some alternative capacity providers are offering decent rates on STM-1s among large cities; pulling VC3s or VC4s out of an STM-1 and paying proportionately has some economic attraction, particularly in cases where competition among providers doing this isn't quite as cutthroat as it is in North America. A "how" diagram following a model other than something closely mirroring the Ebone approacj would be: City A City B provider 1-----\ /-------provider 1 | | provider 2-----ADM===========ADM------provider 2 | | provider 3-----/ \-------provider 3 Where the single-stroke lines represent 45Mbps or 34Mbps circuits, whether through a local bandwidth provider (like the PNO) or using cables or something across a colocation facility like Telehouse, and the double-stroke line represents an international STM-1 provided by a bandwidth carrier. This kind of thing tends to bring the per-bit-per-second-per-month price down quite a bit compared to three individual E3s or DS3s, assuming that pricing is done relative to ordinary PNO tariffs. There are cost and complexity issues for all largeish ISPs to consider when choosing among various approaches for moving traffic around, obviously, so there is certainly on One True Approach to sharing really expensive bandwidth. One observation, however, is that aggregating providers appear to be popular choices when dealing with very expensive lines or high levels of complexity, and unpopular choices when they don't actually solve either problem (like when a large ISP can't use much of its flat-rate paid-for bandwidth because of massive overbooking or other design issues, or when routing and other things break alot). Finally, returning to the question of how many small pipes there are and how much trans-oceanic bandwidth there is, it is worth noting that a large number (but not most) of Ebone's customers have their own circuits across the Atlantic ocean, in spite of Ebone's pricing discounts on people who use Ebone'e trans-atlantic capacity. (Our trans-atlantic capacity is vastly less expensive than our trans-European capacity, and across a full customer pipe, a customer who is receiving U.S.-sourced traffic (or sending U.S.-bound traffic) through Ebone typically uses enough traffic that the cost incurred by meeting that customer's traffic needs is less than the cost incurred if the pipe was full of only European-to-European traffic). In essence, the reason there are lots of trans-Atlantic pipes is that in order to have sufficient capacity one would have to connect with a relatively large pipe to a trans-Atlantic traffic aggregator, which tends to be alot more expensive than a smaller pipe within Europe and a separate pipe across the ocean. This will probably remain the case, price-wise, until intra-European bandwidth prices fall to less than inter-continental prices, or to the point where the cost of connecting to a provider (or multiple providers) within Europe is perceived as less than the cost of maintaining a more complicated network. Sean.

Asymmetry doesn't lead to out-of-order delivery, so this isn't a problem. Routes that *change* often, on the other hand, can indeed lead to performance problems. Vern

Ideally, ingress filtering would be applied as close to the edges as possible. This, for obvious reasons (one of which you pointed out above), isn't feasible. What is feasible is that all providers that possess some amount of cluefulness (this should cover *most* at the public exchanges), deploy ingress filtering on their customer connections. IMO, vendors should only be accountable for providing mechanisms to put these policies in place, most of which already exist. It's the responsibility of the participants of groups such as this to see that those policies are deployed. -danny

Internet Route Filtering
by Robert Malally 21 Aug '97

21 Aug '97

Hello, Does any one truely know what the current route filtering polices are for Sprint and MCI. The following rules are some that I have heard : Sprint currently filters announcements from its non-customers as follows: RFC 1597 reserved space: accept nothing (**) In the classical "A" space: accept nothing longer than /8 In the classical "B" space: accept nothing longer than /16 in 24/8 space: accept nothing longer than /19 (*) in 195/8: accept nothing longer than /19 in 206/8 - 223/8: accept nothing longer than /19 in 192/8 - 205/8: accept nothing longer than /24 (*) in-line with the IP registries allocation (**) RFC 1597> Private Address Space RFC 1597> The Internet Assigned Numbers Authority (IANA) has reserved RFC 1597> the following three blocks of the IP address space for private RFC 1597> networks: RFC 1597> 10.0.0.0 - 10.255.255.255 RFC 1597> 172.16.0.0 - 172.31.255.255 RFC 1597> 192.168.0.0 - 192.168.255.255 How are MCI and Sprint going to adjust their routing polices when the reclaimed class A's are given out. Thanks Robert Malally
