Please clarify. To which network element are you referring in connection with extended lookup times? Is it the collapsed optical backbone switch, or the upstream L3 element, or perhaps both? Certainly, some applications will demand far less latency than others. Gamers and some financial (program) traders, for instance, will not tolerate delays caused by access provisions that are extended over vast WAN, or even large Metro, distances. But in a local/intramural setting, where optical paths amount to no more than a klick or so, the impact is almost negligible, even to the class of users mentioned above. Worst case, run the enterprise over the optical model and treat those latency-sensitive users as the one-offs that they actually are by tying them into colos that are closer to their targets. That's what a growing number of financial firms from around the country have done in NY and CHI colos, in any case. As for cost, while individual ports may be significantly more expensive in one scenario than another, the architectural decision is seldom based on a single element cost. It's the TCO of all architectural considerations that must be taken into account. Going back to my original multi-story building example-- better yet, let's use one of the forty-story structures now being erected at Ground Zero as a case in point: When all is said and done it will have created a minimum of two internal data centers (main/backup/load-sharing) and a minimum of eighty (80) LAN enclosures, with each room consisting of two L2 access switches (where each of the latter possesses multiple 10Gbps uplinks, anyway), UPS/HVAC/Raised flooring, firestopping, sprinklers, and a commitment to consume power for twenty years in order to keep all this junk purring. I think you see my point. So even where cost may appear to be the issue when viewing cost comparisons of discreet elements, in most cases that qualify for this type of design, i.e. where an organization reaches critical mass beyond so many users, I submit that it really is not an issue. In fact, a pervasively-lighted environment may actually cost far less. Frank A.

Understandably, some applications fall into a class that requires very-short distances for the reasons you cite, although I'm still not comfortable with the setup you've outlined. Why, for example, are you showing two Ethernet switches for the fiber option (which would naturally double the switch-induced latency), but only a single switch for the UTP option? Now, I'm comfortable in ceding this point. I should have made allowances for this type of exception in my introductory post, but didn't, as I also omitted mention of other considerations for the sake of brevity. For what it's worth, propagation over copper is faster propagation over fiber, as copper has a higher nominal velocity of propagation (NVP) rating than does fiber, but not significantly greater to cause the difference you've cited. As an aside, the manner in which o-e-o and e-o-e conversions take place when transitioning from electronic to optical states, and back, affects latency differently across differing link assembly approaches used. In cases where 10Gbps or greater is being sent across a "multi-mode" fiber link in a data center or other in-building venue, for instance, "parallel optics" are most ofen used, i.e., multiple optical channels (either fibers or wavelengths) that undergo multiplexing and de-multiplexing (collectively: inverse multiplexing or channel bonding) -- as opposed to a single fiber (or a single wavelength) operating at the link's rated wire speed. By chance, is the "deserialization" you cited earlier, perhaps related to this inverse muxing process? If so, then that would explain the disconnect, and if it is so, then one shouldn't despair, because there is a direct path to avoiding this. In parallel optics, e-o processing and o-e processing is intensive at both ends of the 10G link, respectively. These have the effect of adding more latency than a single-channel approach would. Yet, most of the TIA activity taking place today that is geared to increasing data rates over in-building fiber links continues to favor multi-mode and the use of parallel optics, as opposed to specifying single-mode supporting a single channel. But singlemode solutions are also available to those who dare to be different. I'll look more closely at these issues and your original exception during the coming week, since they represent an important aspect in assessing the overall model. Thanks. Frank A.

minimizing BGP link failure detection time
by Ang Kah Yik 30 Mar '08

30 Mar '08

Hi all, I'm currently getting started out with BGP so if I'm asking the obvious, please forgive my ignorance. On the topic of BGP convergence, may I ask what are the current best practices for ensuring rapid link failure detection - especially when dealing with an interface that is connected to 3rd party L2 infrastructure? e.g. an interface connected to an EBGP peer via Metro-E As far as I'm aware, the most commonly used method to minimize link failure detection time is to tune the keepalive/hold timers. I understand that there are alternatives to this such as BFD and next hop tracking - but support for this is limited on certain platforms. I have looked through this presentation from APNIC 21. http://www.apnic.net/meetings/21/docs/sigs/routing/routing-pres-hughes-bgp.… What do you guys think of the recommendation for timers? (5s and 15s for keepalive and hold timers respectively). However, since the presentation is more than a year old, has BFD become a better solution to this? Looking forward to your suggestions. Thanks -- ANG Kah Yik (bangky)

>So are you envisioning ANY sort of aggregation at all?< Yes, under most scenarios that I have considerd, there would indeed be some nominal amount of optical gear on site, but not very much, and it certainly would result in a considerable net reduction in overall equipment required within a building (and a commensurate reduction in the amount of electric power consumed, as well). In the most "active" case, there could be a DWDM or CDWM rack in the main comms room or building data center feeding a few high-density Ethernet switches occupying several additional racks. From there, however, it's all home-run fiber to optical patch panels on each floor where the LAN closets once stood, and lateral fiber runs out to the desktops, WLAN access points and other shared resources. Compare this to the 80 fully-equipped LAN rooms I discussed earlier --in addition to the main building core switch and associated hierarchical routers-- in the forty-storey building going up at Ground Zero, and the trade off is strikingly in favor of the optical solution. In another scenario, which we'll call the "passive" one, depending on user density and the demand for speed, there could be absolutely no active electronics introduced, at all, only passive splitters, at first, which could be connected via a limited number of dark fibers to a nearby data center. These splitters could be upgraded over time to active WDM-PONs, when necessary, which would amount to occupying a footprint comparable to the first "active" scenario, above. Now, I'm not suggesting that selling the Optical LAN model based on FTTD[esktop] is something that can be achieved entirely without challenges. For starters, due to the approach currently being used to power VoIP phones, for example, detractors are already suggesting that fiber cannot support Power over Ethernet (PoE), which is a standard that assumes the use of Category x UTP copper cabling and copper-based switch ports. There are solutions for this, though, in fact there are many solutions for this, but as in most classic chicken-and-egg dilemmas, there's nothing out there that is currently being used on a broad basis that one can point to. Yet. Likewise, most economical approaches to FTTD today (or it's becoming so, very rapidly, thanks to the economies of scale being brought about in the marketplace at component and subystem levels thanks to the recent acceleration in residential FTTH deployments) would demand singlemode fiber, and this would hold especially true in cases where the collapsed backbone switch is sited beyond several hundred meters from the user, or in another building altogether. But as things stand today, the standards bodies and the IT managers on location who fastidiously (and oft-times blindly) abide by TIA doctrine insist on multimode fiber -- that is, when fiber is specified at all. While I'm on this point, it's interesting to note that, for the sake of maintaining backwards compatibility to the work habits and form factors of older grades of multimode fiber (MMF), MMF has been tweaked, zorked and modified so many times, to the point where it's overall efficacy has reached a point of diminishing returns, IMO, that it has now surpassed its TIA copper cousin in the number of times it has undergone incremental changes. If all of this had resulted in MMF achieving capabiliies even half as effective as SMF, then I'd say it was all worth it. But it hasn't. And its greatest limitation, for my purposes, at least, is the distance for which it can be specked: For high speed applications surpassing 1 Gbps, thd distance rating for SMF is in the tens of KILOMETERS, wheras MMF is still being rated in the low 100s of METERS.

RE: cooling door

I referenced LAN rooms as an expedient and to highlight an irony. The point is, smaller, less-concentrated, distributed enclosures suffice nicely for many purposes, similar to how Google's distributed containers and Sun Micro's Data Centers in a box do. And while LAN rooms that have been vacated, as a result of using collapsed fiber, might fit these needs, since they would have been already powered and conditioned in many cases, those could actually be reclaimed by tenants and landlords as usable floor space in many cases. >I suppose the maintenance industry would love the surge in extra >contracts to keep all the gear running.... Your supposition is open to wide interpretation. I'll take it to mean that you think "more" gear, not less, will require maintenance. Maybe in some cases, but in the vast majority not. Consider a multi-story commercial building that is entirely devoid of UTP-based switches, but instead is supported over fiber to a colo or managed service provider location. Why would this building require L2/3 aggregation switches and routers, simply to get in and out, if it hasn't any access switches inside? It wouldn't require any routers, is my point. This reduces the number of boxes reqired by a factor of two or more, since I no longer require routers onsite, and I no longer require their mates in the upstream or colos. I wouldn't require a classical in-building L3 hierarchy employing high-end routers at the distribution and core levels at all, or I'd require a lot fewer of them. Extending this rationale further, the level of logistics and LAN element administration required to keep on-prem applications humming is also reduced, ir not eliminated, and/or could easily be sourced more efficiently elsewhere. I.e., from a CLI or Web browser the LAN admin could be doing her thing from Mumbai (and in some cases this is already being done) or from home. So there's actually "less" gear to manage, not more. I realize this isn't a one-size-fits all model, and I didn't intend to make it appear that it was. But for the vast majority of enterprise buildings with tenants occupying large contiguous areas, I think it makes a great deal of sense, or at least would be worth evaluating to determine if it does.
