What are the options for securing SD-WAN?

A key component of SD-WAN is its ability to secure unreliable Internet links and identify anomalous traffic flows.SD-WAN technology providers are continuing to increase their native security features and to create robust ecosystems of network-security partners.[ See where SDN is going and learn the difference between SDN and NFV. | Get regularly scheduled insights by signing up for Network World newsletters. ] IT managers should consider their branch network security requirements and carefully evaluate the security capabilities of leading SD-WAN providers, include their native security features and their partnerships with network security providers.To read this article in full, please click here(Insider Story)

How to plan a software-defined data-center network

The data-center network is a critical component of enterprise IT’s strategy to create private and hybrid-cloud architectures. It is software that must deliver improved automation, agility, security and analytics to the data center network. It should allow for the seamless integration of enterprise-owned applications with public cloud services. Over time, leading edge software will enable the migration to intent-based data-center networks with full automation and rapid remediation of application-performance issues.To read this article in full, please click here(Insider Story)

SD-Branch market expected to reach $3 billion by 2022

As long as I have been an industry analyst, network engineers have tried to build multifunction boxes that are capable of addressing a wide range of network functions. These all-purpose network boxes have been lost to history as single-function platforms optimized for network performance (e.g., router or WAN optimization) dominated the market. The branch network is poised to benefit from the advances in software networking to collapse all network functions on to a single platform — the software-defined branch (SD-Branch).A total addressable market (TAM) analysis of the SD-Branch market starts with understanding the total spend on branch networking hardware and software. Worldwide spending on routers, WAN optimization, SD-WAN, network security, Wi-Fi, and ethernet switches at branch locations is approximately $15 billion, according to Doyle Research. (Disclosure: I’m the principal analyst at Doyle Research.)To read this article in full, please click here

Demand for managed SD-WAN services skyrockets

Demand for SD-WAN delivered as a managed service is exploding as customers see the benefits that SD-WAN can bring to their distributed organizations.For example, communications service providers (CSPs) such as Verizon, NTT, and BT all report strong demand for SD-WAN services. Plus, hundreds of other CSPs, cable providers (e.g. Comcast), managed service providers (MSPs), and system integrators have recently deployed new SD-WAN services.Also on Network World: SD-WAN: What is it and why you’ll use it one day | How to make the transition to SD-WAN We also see that managed SD-WAN revenues are growing rapidly as they displace traditional managed WAN services (e.g. private lines and MPLS) — an addressable market of over $40 billion in business services.To read this article in full, please click here

What is NFV and what are its cost, performance and scaling benefits?

Network functions virtualization (NFV) enables IT pros to modernize their networks with modular software running on standard server platforms.Over time, NFV will deliver high-performance networks with greater scalability, elasticity, and adaptability at reduced costs compared to networks built from traditional networking equipment.  NFV covers a wide range of network applications, but is driven primarily by new network requirements, including video, SD-WAN, Internet of Things and 5G.To read this article in full, please click here

Quantifying Benefits of Network Virtualization in the Data Center

vmware-nv-in-the-data-center-business-insights Network virtualization for the data center promises to improve service agility, simplify network operations, and reduce capital expenditures. One of the biggest challenges for IT professionals is to quantify the return-on-investment required to justify the costs of network virtualization and the changes it requires in their data center network operations.
