Network design, architecture, thinking, working. Tech.
I’m responding to Brad Hedlund’s post “On optimizing traffic for network virtualization” where he seems to missed a key point. It’s about cost of ownership in terms of ability to troubleshoot.
I’ve been watching NETCONF and YANG for about four years and it seems that it might be breaking through the noise to set a new standard for Network Management data exchange. In short, SNMP isn’t working and the next generation of “blah blah Cloud” will require more sophisticated communication than SNMP can handle. In the last four years, NETCONF has matured and slowly percolated its way through the industry. Now that is has teamed up with YANG we have something that looks like it’s about to burst into the mainstream.
I have been looking about for documentation on how to configure TACACS authentication with a Citrix Branch Repeater, however so far I have only been able to find documentation for NetScaler. So I have setup a LAB and decided to write the documentation myself. For those who cannot be bothered to read this post there [...]
Some packet generator are more important than others and indeed while a packet is just a packet for us network people if the packets stop moving around the network the way they should it can be a great cause for alarm. I have a customer with such a packet generating devices and it chucks out a 600k udp multicast stream (a single UDP payload) every 5 seconds and if this screws up for any reason then the application is not happy and hundreds of users are very upset. If the packets stop for any length of time then a Severity 1 incident is raised and the customer needs an ass to kick.
Apple has announced the end of Java support for the MAC. This means that all those fat clients so loved by management vendors are looking shaky. About time too, time to piss off those bloody Java software clients and move on.
HP has developed a Cloud Workshop for Managers. Which means that you might not have to teach your managers about Cloud Computing after all. Huzzah.
So a “Mark Johnson – makr324@hotmail.com” – posts a comment on my article on How Long it Takes to transfer data :
While the current Olympics is about as interesting as reviewing firewall rules, the current success of first world nations shows that money CAN buy you success. I’m hoping IT Managers can learn training lessons from this.
I can see some value in external Cloud Computing, but why not just build your own with Cisco ? Take a bunch of leftover machines, that old storage system and get a demo version and make your own.
If you work with CiscoWorks, you often need to restart services for changes to take effect. This tip shows how to chain the stop and the start together on Microsoft Windows.
