MenuetOS, an OS Written Entirely In Assembly Language, Inches Towards 1.0

laptop006 Re:QNX? (372 comments)

It's only the core of IOS-XR, and in fact will be gone in the next release (which will share a Linux core with NX-OS and IOS-XE)

Top US Lobbyist Wants Broadband Data Caps

laptop006 Re: Help us Google Fiber! You're our only hope. (568 comments)

More like 16Tb per fibre pair in each direction, most of the major commercial vendors (ALU, Infinera, Ciena, etc.) have 4+ Tb systems out.

And long-haul fibres are usually getting towards 372 fibre, even metro rarely goes less than 72 fibre.

Only submarine systems run much lower than that, with a usual limit of 8 or 16 fibres due to the requirements led by inline amplification.

Your Next Network Operating System Is Linux

laptop006 Re:Actually the majority have not (192 comments)

IOS-XR is migrating to Linux in the next major release, NX-OS (the OS for their Nexus DC kit) is built on Linux, and IOS-XE which powers most of the smaller side of new Cisco kit is also Linux.

As for Juniper they also have many products running on Linux.

Alcatel-Lucent Cuts Go Deeper — 7,500 Jobs Gone and Counting

laptop006 Re:The problem is (78 comments)

Er, No.

The "big boys" are the IP networks, and have been for years, in practice there's two major vendors (Cisco & Juniper) and a bunch of also-rans that can play somewhat (ALU and Brocade [Foundry]).

ALU kit can run core & transmission, but it's not the top tier kit.

The "big boys" are also migrating wholesale to 100g links as their multi-terabit backbones get painful to manage with trunked 10g links.

MySQL Founders Reunite To Form SkySQL

laptop006 Re:The crying game (215 comments)

MySQL still has nothing built in for that purpose

MySQL has had inbuilt multi-master clustering since before PostgreSQL even had master/slave built in.

Some Windows XP Users Can't Afford To Upgrade

laptop006 Re:Helps but not a complete solution. (953 comments)

That's utterly false.

It's the stateful firewall that's doing that, which is a pre-requisite for some common forms of NAT.

Most, if not all, IPv6 supporting consumer routers by default have a firewall configured on IPv6 with essentially identical semantics to that for v4, allow all out, allow nothing in.

Intel Confirms Decline of Server Giants

laptop006 Re:If Google sold servers... (152 comments)

"bonded/trunked NICs"

Why does that matter? The only justification for bonding with 10g these days is "redundancy" and I've seen many more outages (at a variety of sites) from people failing at bonding than I have from switch failure.

If a machine is that critical the service it runs shouldn't live on a single machine.

Even at my last job where we had a design based on multiple SPOFs we lost machines to PSU or drive/RAID failure several times, but never network, except for the one site that did "redundant" NICs.

Sale of IPv4 Addresses Hindering IPv6 Adoption

laptop006 Re:Every host a peer, and chicken in every pot (214 comments)

How is it a bad thing?

You firewall it just the same, so the only change in traffic flow is the lack of NAT, and NAT is not security despite what some people will try and claim.

Ask Slashdot: Enterprise-Grade Linux Networking Hardware?

laptop006 Switches (140 comments)

Pretty most software devices I've seen have either been a rebadged Dell or Supermicro, with the top end running custom cases, and the low end doing whitebox.

In terms of "real" networking kit though, there is a bunch of switches that run linux:

Arista (everything)
Extreme (everything running XOS, which is all current models)
Cisco (everything running IOS XE, the only switch being the 4500-X)

All Juniper devices that run JunOS are FreeBSD, this includes both the EX and QFX switch lines, as well as their SRX firewalls.

Also most of the openflow-aimed switches run Linux, eg http://www.pica8.com/

Ask Slashdot: What Type of Asset Would You Not Virtualize?

laptop006 Re:Busy databases (464 comments)

RAID-DP (usually) is NetApp's name for what's essentially a RAID6.

RAID5/6 work fine for databases, just like RAID10 you have to size it correctly accounting for your read/write load.

Really any form of RAID (if you need the size) with as much RAM and SSD caching is the way to go these days.

Why Your IT Spending Is About To Hit the Wall

laptop006 Re:Lots more than just CPU and transfer resistors. (301 comments)

Or just use colored optics and a passive mux.

Unless you're going hundreds of miles (at which point FC has probably broken anyway due to latency expectations) you don't need active DWDM kit, passive muxes are a much better solution, and far cheaper.

Comcast Not Counting Their Video Service Against Bandwidth Cap

laptop006 Re:IP Insanity (284 comments)

Ethernet most certainly is a broadcast technology, and it and IP have supported multicast for many years (IP multicast across several networks is very common on research networks).

As for bandwidth, assuming 20Mbit streams (fairly standard BluRay, broadcast in some parts of the world approaches it as well) you can fit 500 channels on 10G. In practice as you only have to send out what at least one client has requested you can have more channels then can be streamed, cable companies do this already with Switched Digital Video.

Comcast Not Counting Their Video Service Against Bandwidth Cap

laptop006 Re:Doesn't violate network neutrality? (284 comments)

That's almost entirely false. (ISP network engineer in Australia here)

The major cable leaving Australia for the last decade has been Southern Cross (there's more now) and the Australian government have no significant interest in it (the NZ government on the other hand does by way of cable system part owner Telecom NZ).

iTunes downloads (at least some of them) are cached by Akamai, and traditionally most medium to large ISPs hosted Akamai caches inside their network (at $JOB[-1] Akamai was ~30% and Google was ~15% of all bandwidth used for a regional education network).

It truly isn't any different for any other CDN, some host inside Australia and peer with local networks (IIRC Limelite do this), some only host in Asia (eg Amazon), and some (eg Steam) install machines inside ISPs for their customers.
