IPv6 - the move is on.....slowly

As we all know, IPv4 ran out early February and it's becoming clear that IPv6 implementation is quite important to more people and companies, especially those in the Telco/ISP business and large customer facing companies like Google, etc.

It is also quite clear that hardware manufacturers are still not pushing IPv6 adoption into their new units and even software. The most common being firewalls.

Pick any main firewall supplier for typical home or small business use and you will most likely find it hard to find any of the cheap end units that support IPv6 and usually the high end units would support IPv6.

Even in the software market it seems firewalls again fail to support IPv6. When linux has been supporting IPv6 for a long time, you would expect that by now contributors and developers on packaged linux firewalls were already working towards it but I had a hard time finding any info on when it's due to be supported in popular ready made distros for example.

IPCOP - no support

Endian - no support until sometime in version 3 (current v2.4.1)

PfSense(FreeBSD)  - implemented but better support in 2.0

So in the linux world, you seem to have to write/build your own without a gui to get your migration testing started.

 

I'm sure in the next couple of years we'll start to see more and more hardware and software adopt the move to IPv6 as there are more questions asking about it and more demand is there.

Bell labs breaks the transmission speed record

Using WDM or Wave Divison Multiplexing technology, Bell Labs have created a new milestone by using over 150 lasers running at different wave lengths and pushing through 100Gb/s on each wave length.

This will increase the high demand of todays bandwidth and will raise the bar for future technology advancements.

New special transceivers were needed to be made to be able to separate and detangle the information coming in and out of the fiber cable.

 
Xen 4.0 roadmap released

Only just as Xen had release their 3.4 release back in June they have now started on their roadmap to version 4.0 of the Xen Hypervisor.

New great features include :

  • RDMA Live Migration Support
  • Dom0 kernel in Linux 2.6.30 or later
  • Dom0 support for Marvell 6480 disk driver
  • Pass through USB-Controllers/Devices for PV Guests
  • Fault Tolerance - Project Remus and/or Kemari
  • Monitor, Limit, Control network traffic coming at DomUs
  • Internationalization / Unicode Support
  • Configure Virtual Bridge like Real Switch (e.g. Control VLAN, port status)
  • VLan tagging per NIC in the VM Config File
  • Virtual Ethernet Switch
  • Physical Xen boot/install support via native UEFI (pUEFI) and virtual UEFI (vUEFI) support
  • Limit I/O for individual disks of VM (similar to credit scheduler weight)
  • Dynamic Memory Management for Overcommiting RAM
  • PCI CGA Passthrough for VT-d (vendor cards like Nvidia, AIT, etc)
  • Full AMD IOMMU Support
  • Online resizing of DomU Disks
  • Cross compliling Xen and Modular Builds

 
KDE 4.3 released

KDE 4.3 (a.k.a Caizen) has been released. A whole bunch of bug fixes has been made and it looks like KDE has come a long way from the old days.
