Cisco Borderless Network – ISR Generation 2

Last week I participated in a one-day workshop which took place at the Cisco office in München. The new Cisco vision of the borderless network was introduced and the main focus was on the new Integrated Services Router (ISR) Generation 2.

The whole idea of this vision is that the “borders” in the network will soon disappear and one will be able to connect to the network from anywhere, at any given time, from any device and to any resource. And all this will be done transparently and securely. One will no longer be limited by the device used (be it laptop, desktop, smartphone, etc) nor will he be limited by the type of connection (wired, wireless, mobile, etc). The network will be intelligent enough to adapt and provide a seamless experience.

What interested me the most was the new ISR G2 series, which is a key player in the borderless network concept. There are new versions to all the previous ISR routers and the upgrades are significant. I won’t bother you with too many details, but couple of things stand out:

  • 3 new models of the small 800 series, new 1900, 2900 and 3000 series
  • all of them run a universal IOS image, IOS 15.0 will be released.
  • the image contains all features. The individual features are activated on-demand, as they are needed
  • multi-core processors
  • crypto engines are already onboard
  • field-upgradeable mainboards (Service Performance Engine, SPE)
  • Multi Gigabit Fabric (MGF): the individual modules will be internally directly connected at gigabit speeds

There are of course other changes but I think those are the most important.

After the ISR G2 presentation, a few more things were discussed about topics such as Security, WAAS (Wide area application services) and the ASR 1000 (Aggregation Services Router).

Otherwise things were nice, the presentation was good, no blue screens or anything. And the canteen over there makes really good food! ;-)

Online for good

After only three weeks ago I had murderous thoughts towards Deutsche Telekom, now I came back to more peaceful feelings. Finally the internet works decently at home. I still don’t have VDSL because it’s not yet available in my area but I do have 16 Mbps ADSL2 with the Telekom’s package Entertain Premium. A couple of the interesting features of this package:

  • fixed telephony flatrate
  • internet flatrate (of course!)
  • decent actual speed, 12-13Mbps
  • good upload for DSL: 1Mbps
  • IPTV which works, good quality
  • flatrate for all Telekom hotspots in Germany, 8000 of them or so

So I am kinda pleased so far. I am also in the process of setting up the multimedia system in the bedroom. After quite some searching we decided for a Fujitsu Siemens Amilo SL 3230T 23 inch monitor and a Zyxel DMA1000 digital media streamer. We’ll use this to watch the movies and episodes we have on the network server and for the TV part we’ll just get another receiver for Telekom’s IPTV. We don’t need a DVD player because we don’t really watch them but should the need arise, I can always just rip it and put it on the server.

I really hope the internet problems are gone, knock on wood!
