Work Diary: A bit of BGP (Border Gateway Protocol)

We manage a couple of BGP Autonomous Systems (AS) for a service provider client. Today we have been advertising some new prefixes out of  1 autonomous system, ensuring that we have multiple connections announcing the same ranges for resiliency and diversity. Gconnect , as Cisco Cloud and Managed Service Partners, can leverage our experience in managing large Cisco networks whilst maintaining controls, checks and balances. Although we use a formal change control process, stringent backup and configuration archiving we are still agile enough to perform an update like this in a couple of hours, rather than days. You can find out more about how the internet is glued together with BGP (Border gateway Protocol) here.

Work Diary: Making sense of NFSen

We recently took on new client who was hosting a SOAP server on the end of 2mbps leased line. The line was being completely flat-lined and the service was all but unavailable. Unfortunately, the networking hardware on site was pretty ‘basic’ so it was not possible to see what the issues were. The client had decided that as this service was mission critical they would move the 2 servers into the cloud, and then the extra bandwidth available would probably solve the issue. After the ¬†initial install and server setup, we were able to analyse the data going to and from the server using a Netflow collector. This analysis identified the issue and the customer was able resolve the issue by speaking to the owner of the offending server. By using proprietary Cisco networking equipment and firewalls we are able to export Netflow data to our collectors which run on FreeBSD and NFSen, giving customers access to a wealth of data to help keep their businesses running at their best.
