Pluris routers
by Bob Biver 15 Oct '00

Is anyone using these in their core? If so, how is interoperability w/ Cisco (Stratacomm) MGX, Juniper M20 and Nortel passports? http://www.pluris.com/pdfs/Pluris_Arch.pdf Thanks, Bob- _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Yes. (although interop with Cisco's is pretty smooth.)

They probably won't. But by that time, everyone hopes there will be a new up-and-coming competitor. The founders will probably be ex-employees who got feed up with the bigness, and started the next company. IBM -> Digital -> Compaq -> Dell -> ???? There are already several companies nipping at Juniper's heels. This is a good thing. When companies start focusing on strategic architectures, alliances, and certifying; they stop innovating.

netscan.org update
by Troy Davis 14 Oct '00

14 Oct '00

Greetings, netscan.org now has a list of the ASNs announcing the most smurf amplifiers, available at: http://netscan.org/most-active-asns.html It's not currently being dynamically generated, but it will be in the next few weeks, when we will probably increase it to show the top 1000 and perhaps add more information (email address, number of amps, average amplification, amps as a percentage of total class Cs being announced). Also, we're in the process of emailing the administrators of these ASNs; about 20 have been notified so far and the other top ~230 will be emailed this week. Each email includes an introduction and current list of amplifiers from that ASN. It's sent to the ASN admin contact and where possible, the NOC, abuse, and/or security contacts, since many backbones have different departments for each. We're also working on a list of amps sorted by ASN. In the meantime, if you administrate or are responsible for an ASN, email sysop(a)netscan.org for a list of its amplifiers. The other lists - one complete list sorted by IP address, one sorted by # of responses, and a short list of the biggest top 2048 amps - are regenerated each night with results from that day's scans. Every day, all known amplifiers are rechecked and periodically all routed class Cs are checked. The main netscan.org site links to these lists as well as information on the attack. Cheers, Troy

64 Megs of Memory...
by Segal, Mark 14 Oct '00

14 Oct '00

One of my old upstreams which we still run a little traffic through only has 64 Megs of memory in a 7202, and it seems like it is running out of memory with full tables. I have not been on the router to verify, but I am receiving 88473 prefixes from them. Anybody else seeing this? Mark -- Mark Segal Director, Network Engineering Axxent Corp. Tel: (416)907-2858

The Cidr Report
by Tony Bates 13 Oct '00

13 Oct '00

This is an auto-generated mail on Fri Oct 13 12:00:01 PDT 2000 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.

Peering Traffic
by Durga P Gangisetti 13 Oct '00

13 Oct '00

HI, A quick question. (Q) What percentage of the customer traffic uses the peering links in the case of a TIER - I service provider? TIER-I Servier providers can be Sprint, BBN, UUnet, AT&T and others. I know that it might depend on the service provider(ISP) individually a/c to peering policies. But an approximate percentage like 40,60,80... will be helpful. Remember that certain percentage of traffic just doesn't leave the network -or - remains within the network. IMP: Assume all the peering traffic is 100% customer traffic ONLY. BTW, the definition of "peering" being an exchange of traffic between ISPs without exchange of money. Thank you, DurgaPrasad V Gangisetti.
