What do successful networking branches require today?

Short answer: A modern branch network needs four things: simple management from one interface, more than one WAN link (wired plus 4G/5G) for failover, SD-WAN to route application traffic over the best link, and layered security such as zero trust access, secure Wi-Fi and a next-generation firewall. Enterprises with many sites can get all of this in one router with central management.

In the realm of contemporary enterprise expansion, branch networks have changed significantly. This evolution from a simple linkage between computers to a complex web of users, sites, and devices has redefined the essentials for operational excellence and growth.

How have branch networks evolved?

Technological advancements and shifting enterprise needs have propelled the metamorphosis of networking branches. The advent of broadband technologies introduced Wi-Fi and wireless networking, liberating devices from physical cables and enabling unprecedented flexibility in connectivity. The subsequent integration of ultra-fast fiber optic connectivity empowered cloud computing, facilitating remote access to servers and data centers. This shift emphasized the critical need for uptime while ushering in the era of IoT devices woven into everyday operations.

What does a modern branch network need?

1. Simplified Network Management: A modern network must be easy to deploy, manage, and troubleshoot. Streamlined architectures and security solutions that can be managed from a unified interface allow IT teams to focus on strategic initiatives.

2. Diverse WAN Link Options: Connectivity is the lifeblood of modern businesses. Hybrid WAN links and failover solutions ensure continuous connectivity, with wireless WAN links like 5G and LTE emerging as reliable alternatives in areas where wired connections pose challenges.

3. SD-WAN Technology: SD-WAN’s cloud-managed policies optimize application traffic routes, enhancing the quality of experience (QoE).

4. Blended Security Measures: Layered defense systems, including zero trust security models, ZTNA, secure Wi-Fi solutions, and next-gen firewalls, ensure comprehensive protection without compromising user experience.

How can enterprises manage many branch sites?

Enterprises managing widespread sites can efficiently address their edge networking needs through hybrid WAN routers that incorporate cloud-managed SD-WAN features, diverse WAN links, Wi-Fi, and zero trust technologies, everything with Nexapp’s Instaroute. Our centralized management solution serves as an efficient and scalable approach to support the rapid expansion of fixed sites.

In conclusion, the prerequisites for successful networking branches today revolve around adaptability, reliable connectivity, stringent security, and a cohesive framework that aligns with evolving business landscapes.

Frequently asked questions

What are the essential parts of a branch network?

Simplified central management, diverse WAN links with failover, SD-WAN traffic steering and layered security including zero trust access, secure Wi-Fi and a next-generation firewall.

Why should a branch have more than one WAN link?

A second link, often 4G or 5G where wired lines are hard to get, keeps the branch online when the main link fails.

What security does a branch network need?

Layered defences: a next-generation firewall with IPS and web filtering at the edge, zero trust access for users, and secure Wi-Fi. Nexapp combines these with SD-WAN on the SASE framework.

Can one device handle SD-WAN, 5G and Wi-Fi at a branch?

Yes. Nexapp's Enterprise X Series edges such as the IRX100-5G combine SD-WAN, 5G SA/NSA and Wi-Fi 6, and are managed centrally from the Nexapp Controller.
