In networking, as in life, we often use the same terms to mean many different things. One of the biggest culprits of this in networking is “edge.” An edge device is usually considered to be a device that connects into a network in only one place. Traffic can flow from an edge device, or it can flow to an edge device, but it can never, ever flow through an edge device. I say never—that’s not entirely true, but I’ll get back to that later. In a campus network, the edge devices are things like users’ computers, laptops, and printers; mobile phones; and tablets.
In data centers, the end devices are servers or, more than likely in the SDDC, virtual machines, or possibly containers. The exception to the rule about traffic not flowing through an edge device is the “edge router,” which more often than not takes the form of a firewall: a perimeter firewall. If we consider north/south versus east/west traffic flows, north/south traffic flows move between the edge and the core, and east/west circumnavigates the network, to take the globe analogy a step further. This distinction becomes important as we look at the direction that networking has taken, and the direction I believe it will continue to take.

Vyatta are slowly becoming one of my favourite networking start-ups…
Not only do they have a first class Router and Firewall/VPN product – boasting higher performance than Cisco – that they give to the community (here), they now offer free training at the Vyatta University!
Back in March, Vyatta Core reached v6.0 providing additional features that make their product more attractive to the enterprise.
- Netflow / sFlow logging and analysis
- 802.11 wireless LAN – (access point + base station)
- Binary image installation – (version mgmt)
- IPv6 readiness (core routing and firewall)
- Firewall enhancements
- IPv6 firewall
- P2P firewall
- time-based and zone-based firewall rules
- QoS Enhancements
You may have read my post on using Vyatta as a Router-in-a-box for VMware and Citrix…
Seeing how this is such an attractive use case for this product, Vyatta have published a course detailing installation, verification and basic configuration of Vyatta OVF and XVA virtual appliances for adding routing & security to VMware ESX and XenServer environments.

I very much like Vyatta’s approach, offering the Core Edition to the community with support subscription available as an uplift and it is even more refreshing to see Training following in the footsteps.
A strong community and easy access to resources satisfies engineers and will yield a greater amount of knowledgeable/certified individuals should Vyatta choose to go down this route.
Perhaps more Networking vendors could learn from this…
