SDN–Software-Defined Networking

The Importance of Standard Management Interfaces

By Hassan Dakroub, Customer Solutions Architect

The wave of virtualization is catching up in every vertical of technology, and new protocols are being defined to improve functionality and management of emerging technologies. Software-defined Networking, or SDN, is one of those technologies. SDN was first used in data centers to configure network devices connecting virtual machines amongst themselves and the internet on a massive scale and is now being adapted into other applications and technologies.

Segment Routing 101 and the Future of MPLS

By Said Jilani, Sr Customer Solutions Architect

Segment Routing is a new routing paradigm that aims to optimize, simplify, and improve the scalability of IP/MPLS based networks. Segment Routing utilizes source-based routing scheme where a network node steers a packet based on a list of instructions carried in the packet header (called “segments”). The list of segments carried in the packet header provide a strict or a loose specification of the required network path or tunnel eliminating the need for transit nodes to hold and maintain that path/tunnel information.

SDN in the Backhaul: All About Reducing OPEX

Figure 1: SDN will not significantly reduce microwave CAPEX costs.

Software-defined networking (SDN) promises to drastically simplify how transport networks deploy, operate and get serviced. Reducing OPEX remains a significant factor for implementing software-defined networking. Automating service creation, traffic and bandwidth control, and network management as well as reducing maintenance complexity of routing protocols remain areas where it will simplify backhaul and lower OPEX. The only questions seem, “When will this happen?” and “How much will it save?” And what about CAPEX? Can we expect reduction in purchase price of microwave backhaul based on such a migration?
