Network Consulting

My experience

I have experience of designing everything from data centre, office, to home networks.
In my selection of equipment I try to stay vendor neutral, and will avoid locked-in solutions and proprietary protocols.
No matter if it’s a network for 5 clients or 10 000 servers, I can advice on your setup.

I’m used to, and adaptive to working with:
– Small office networks <20 clients / 10 people
– Scaling office networks from <300 clients / 150 people to >2000 clients / 1000 people
– Data centre networks (mainly for physical hosts) from hundreds to thousands of servers
– Data centre to cloud connectivity (Amazon VPC and Google Cloud Platform for example)
– Wireless point-to-point networks

My preferred technologies:

If it comes to designing a network from scratch, I like to use the following protocols/technologies:
– eBGP for routing
– As little L2 as necessary
– L3 to top-of-rack
– Spine/leaf architecture
– IPSec VPN + eBGP for securing traffic across the internet (site-to-site and office-to-site)
– 802.1x + FreeRADIUS for wireless and wired authentication of clients
– SNMP + sFlow/netflow for monitoring
– Ansible for automation (“SDN”)
– Wavelengths or dark fibre + DWDM for interconnecting sites
– Transit (ISP’s), peering
– Out-of-band networks, console servers etc

Software, vendors and hardware platforms that I am comfortable with:
– Fortinet Fortigate
– Juniper SRX
– Juniper EX
– Arista
– HP (for switching)
– Cisco Aironet / WLC
– Cisco ASR (IOS-XR)
– Cisco IOS
– Ubiquiti airMAX
– Pfsense

I have worked with all of the above from single RU size to 10+ RU chassis.
