Full Abstract

This BOF gives the ARIN Advisory Council an opportunity to gather feedback from the NANOG ISP community regarding Micro Allocations. The BOF is not intended to set ARIN policy or for discussion of any existing ARIN policy. If this discusson is useful, it may be that the same BOF occurs at other regional registry meetings and other ISP functions.

What is a Micro IP Address Allocation?

Micro IP Allocations are small, portable, blocks longer than a /20, and perhaps as long as a /24 or longer, to multi-homed entities. It has been suggested that these micro allocations be out of some defined block of space that is known to ISPs (similar to the Swamp that we know and love).

Summary of the Lively Discussion at the Last ARIN Meeting

It has been discussed that when folks dual-home they currently often advertise the longer prefix into the global routing tables for anyone who will listen. Some say that micro allocations will not cause any additional route advertisements because they're already there. The counter argument to this is that all of these longer prefixes are still reachable via the ISP's aggregated route, and micro allocations would not be.

It was brought up that ISPs' customers who want full Internet routes will have to buy heftier routers because of this. In addition, the ISPs will also have to do that themselves. It is the case, however, that if the block is well known, ISPs can aggregate it and announce the aggregate to their customers, thus keeping them from having to bear the burden of the added prefixes. It was also suggested that ISPs could filter on this block and perhaps begin charging folks who want the ISP to listen to the more specifics.

Agenda

• ARIN Advisory Council members who are present introduce themselves.
  
  
• Update on ARIN open policy meetings and who should attend.
  
  
• Micro Allocations - what are they? State purpose of the BOF (what the BOF is what the BOF is not).

• Presentation of various micro allocation schemes.
  
  
• Discussion with attendees about the different schemes, their impacts, etc.

Full Abstract

A project has been started to study network pathologies (why, how, and when things fail), initially using BGP churn data as gathered via eBGP feeds from many ASs to follow prefixes, ASs, and inter-AS links that are failing or congesting. Data will be tracked over time, but one goal is to be able to provide more instantaneous data about Internet failures.

We will present:

• Motivations for the project;
• An overview of the infrastructure of the project;
• The initial set of parameters being studied; and
• Very preliminary data.
  
  

We will be seeking input on a number of topics, including what information people would be interested in seeing data on, and what information people feel should be released or kept private.

Full Abstract

Broadband services, such as DSL, are now being rolled out by multiple telcos in Tier 2-4 markets. Traditionally, these markets have not been stopping-points for the major backbone providers (Sprint, UUNET, iMCI, CW, et al.) and as such don't have high speed transit connections (DS3 and above). In addition, these locations do not have good local peering meet points, or IX's, for local or regional traffic.

Currently, the major peering points are the MAE's and PAIX. Most large providers will only peer with a local/rural ISP if they can make it to these locations. However, the distances, and thus the mileage-based cost for circuits to these locations, are extremely expensive. For example, a DS3 from ABQ to PAIX will cost between $20,000 to $45,000 per month, and that is just the circuit cost. One still has to obtain space and a router at PAIX.

Major backbone providers currently do not see a need to put large POPs in these Tier 2-4 cities. They cite the "lack of demand" for services which, one could say, is a myopic point of view. DSL is exploding in these markets and the demand is there now. The transit links are not.

If an ISP wanted to get a DS3 to UU.NET (even Frac DS3) it would have to pay backhaul to PHX or LAX or DFW. This increases the cost of the transit beyond what most local ISP's can afford.

If broadband services are going to be sucessful in these markets, the local ISP needs to have better access to better networking.

In other words, we would like to encourage:

• The promotion and education of local IX's.
• The creation of local IX's.
• Better access to backbone transit vendors without the backhaul costs.
• Regional and national backbone vendors exchanging routes at locations other than the current MAE's/PAIX's.
• The willingness to peer at local IX's, and not just local routes
  
  

14 to 18 hops shouldn't be required to Yahoo / AltaVista / and other major sites from these Tier 2-4 locations.

The RIPE-NCC Test Traffic Measurements project is an implementation of RFCs 2330, 2679, and 2680 on one-way-delay and packet-loss.

In order to measure these parameters, dedicated measurement stations ("test-boxes") have been installed at 40 ISP's in Europe and the USA. We plan to double the number of measurement points in 2000. Several products and services based on the Test Traffic Measurements data have been developed and are being offered to sites participating in the project, including:

• Plots showing the delays and losses from/to each participating ISP over time,
• Network alarms, when network delays are above the expected values,
• A regular report showing the quality of connectivity from/to an ISP, and
An overview of network delays over a longer period, in order to assist ISP's in the planning of future network upgrades,

This presentation will give an overview of the project, show more details about the products that are being offered to sites hosting a test-box, and call for sites interested in joining the project.

Full Abstract

Routing decisions between ASs are derived from reachability information exchanged via routing protocols (BGP) between these AS's, as well as local policies. The Routing Information Service (RIS) is a new project at the RIPE-NCC. The goal of the RIS is to collect time-stamped BGP updates from default-free border routers of many ASs, at topologically interesting network points. These updates will be stored in a database that can be queried interactively by the community.

The information stored in the RIS can be used, amongst other things, to understand network reachability from remote locations for tracing past routing problems, for reality checks of routing policies registered in the various Routing Registries, and for statistical analysis.

This presentation will introduce the RIS project and show some first results based on the first development version of this service.

More details are available from the http://www.ripe.net/ris/" TARGET="_BLANK">RIS Web site.
