Optimizing VPN Performance and Availability with Network Observability by Broadcom

Key Takeaways

Employ Network Observability by Broadcom to gain a unified view of traditional, Wi-Fi, software-defined, and multi-cloud environments.
Leverage insights needed to ensure VPN networks are continuously delivering optimized availability and performance.
Establish monitoring dashboards and alerts that enable more intelligent, proactive network management.

In recent years, hybrid work approaches have grown increasingly commonplace, and for a significant percentage of users, VPN is the go-to approach for accessing secured corporate resources and services. In fact, one article reveals that 72% of desktop and laptop users employ a VPN.

As the reliance on hybrid work models and VPN connectivity continues to grow, VPN health has emerged as a critical success factor for businesses. If VPN users experience poor, erratic performance or downtime, they can contend with significant disruptions. As a consequence, user productivity, and business results, can suffer.

Challenge of tracking VPN health

For IT and network operations teams, it is vital to ensure that VPN users have an optimized experience. The challenge is that monitoring and managing service levels is now extremely complex.

Issues can arise on the data center side for a range of reasons, including expired licenses, dropped connections, maxed out gateways, and many more. In addition, an issue can occur on the users’ side, such as on the users’ ISP network, the Wi-Fi they’re using at home or in a café, and so on.

The solution: Network Observability by Broadcom

Network Observability by Broadcom equips operators with a unified, end-to-end view of traditional networks as well as modern Wi-Fi, software-defined, and multi-cloud environments. The solution provides the visibility that teams need to ensure VPN networks are continuously delivering optimized availability and performance.

With the solution, teams can establish monitoring dashboards and alerts that enable more proactive management. With the solution, teams can:

Discover key infrastructure, including VPN gateways and WAN interfaces.
Monitor key performance indicators (KPIs).
Gain fast, intelligent insights into problem areas, so they can immediately focus on resolution or escalation.

The solution offers unified alarm workflows, tracks concurrent connection trends, and reports on license counts for VPN connections.

Key solution offerings

Network Observability by Broadcom features these products:

DX NetOps. DX NetOps is a scalable, on-premises software offering that delivers advanced capabilities in such areas as network analytics, operator dashboards, data correlation, and third-party integration.
AppNeta. With AppNeta, teams can actively monitor network delivery experience over paths to cloud, SaaS, and other external sites. AppNeta enables IT operations teams to fully understand how performance is affected by common issues like application outages, route changes, connectivity drops, and ISP peering changes.

Extensive coverage of network performance metrics

In VPN environments, AppNeta can monitor various KPIs. The product’s continuous path monitoring enables extensive coverage of these network performance metrics:

Connectivity
Capacity
Data loss
Data jitter
Latency
Round-trip time (RTT)
