Joshua,
We use the Juniper 2xx series IDP; highly recommended. We are a small financial intuition with about 200 employees and 13 branch locations.
I'd stay far away from SecureWorks if you're looking to manage the device yourself; if you're looking for an overpriced managed solution then they'd be okay.
Ryan

Hi,
I have been tasked to get the best IDS and IPS for our internal LAN and WAN in a Banking infrastructure. I would like ask if any one has deployed in any network with such technology, and also if any one can recommend a very good IDS and IPS for me to recommend to management
Thank you.

Mere deprecation does not stop propagation of such paths.
That's very true, but it *does* move us in the right direction -- saying "Aggregation that results in AS_SETs is prohibited, off with your head" isn't going to fly in the IDR WG when there are routes that use them...
Suggesting the people do not perform aggregation that results in the creation of AS_SETs (and AS_CONFED_SETs), and that operators filter such announcements will lead to a time where they just don't exist any more [0] (and then can be removed from the protocol).
We are also specifying that new BGP work does not need to support AS_.*SET ;-)

just to uncloak a bit. when we first decided to look at deprecating as-sets et alia, we begged olaf maennel to analyse the use thereof. the following is edited from internal email from early august. we then begged one of our number, warren, to do the dirty, and he was kind enough to do so. we owe him.
---
using data from ripe r00
years total real stable as-sets as-sets 7 4 2 6 6 2 5 20 3 4 22 5 3 64 16 2 214 87 1 875 289
years stable is how many years that as-set was announced for that prefix.
total as-sets is the number of prefixes that had any as-set.
real as-sets is the number of prefixes with as-sets which were not singleton asns and were not private asns.
olaf scanned for ten years but none were stable for more than seven.
in ten years, 1205 different prefixes with as-sets were seen. removing private asns and removing singletons left only 404 prefixes over the ten years.
he did not check for covering prefixes, i.e. two prefixes with the same as-set where one was a sub-prefix of the other, longer, one.
and i suspect the data are somewhat self-similar. i.e. the 289 that were stable for the last year may have shorter term components which were much higher. i.e. looking at data for a week or a day may give higher values.
a graph which should be pretty self-explanitory may be found at
http://archive.psg.com/fraction-and-absolute-number-of-ASsets-in-table-over-...
it is interesting that, at no time, i.e. in no single rib dump, were there more than 23 prefixes with as-sets. while this is suspicious, it seems to be true.
