Nick is a network engineer at the Energy Sciences Network (ESnet) of the Lawrence Berkeley National Lab (DoE). He’s part of the distributed team responsible for managing a heterogeneous, international, high-performance network consisting of production MPLS/VPLS, L2, L3, and disruptive technologies layers (OpenFlow, SDN and dark fiber) connecting all US Department of Energy sites and other research and education networks. He is also a Network Engineering member of the security team.
Opinionated and hard hitting, Buraglio has the kind of style and talent IT managers love.
SDX, SDN, and security measures at Internet exchange points. The security aspects, specifically in the WAN, have been an afterthought, he says, and he wants to advocate for a “secure by default” software-defined wide area networks and traffic exchanges. Fundamentally, Internet exchanges use BGP “trust models” to secure traffic that he feels are limited. He sees the trust models depending on deprecated security that is in dire need of refresh (as is BGP in general). In a software-defined IxP, there needs to be a better way for not only validating resources but also potentially providing authorization into other software-defined autonomous systems.
It is particularly important. WAN connectivity is the stitching that holds together the cloud environments and is even less friendly to interruptions and problems. The data center is important in that data center architects and engineers are working through some of the fundamental and foundational issues within a software defined networking.
He’s excited about network virtualization. Network Function Virtualization, or NFV, in the wide area is going to be an important capability in future WAN architectures. Leveraging existing resources to provide functionality that has historically been provided by financially and operationally expensive devices will change how networks are managed and deployed, and allow for greater flexibility for lower cost.
