Understanding Quality of Service (QoS).

Before we dive into Dynamic QoS, at its core, Quality of Service (QoS) is a technology designed to manage network traffic effectively. It prioritizes essential applications over less critical ones, ensuring that important network activities, like video calls, receive precedence over lower-priority tasks, such as streaming videos on Netflix.

Goals of QoS

• • Reduce Packet Loss: Ensures data packets reach their destination reliably.

• • Minimize Latency: Decreases the delay before a transfer of data begins following an instruction.

• • Eliminate Jitter: Avoids variations in packet delay at the receiving end, important for quality in real-time communication

The Evolution of Dynamic QoS

Traditional QoS systems operate on predetermined rules that allocate bandwidth to prioritized applications and create virtual queues for data packets. This method follows a basic first-in-first-out principle, where bandwidth is reserved for prioritized traffic.

Transition from Tradition:

• Dynamic QoS transcends these limitations by utilizing intelligent software to monitor and adjust traffic rules dynamically for optimized performance. Here’s how Bigleaf elevates this process:
• Intelligent Identification: Bigleaf identifies application traffic dynamically.
• Real-time Adjustment: Continuously adjusts QoS policies based on current network conditions to ensure high-priority traffic like VoIP, SSH, and Remote Desktop is not hindered by ISP congestion.

The Business Case for Dynamic QoS

Without effective QoS, network traffic can become chaotic, akin to rush-hour traffic with non-functioning traffic lights, leading to significant performance degradation. Bigleaf automates the identification and prioritization of traffic, eliminating the need for constant manual monitoring.

Benefits for your business:

1. Enhanced Productivity: Optimizes latency, allowing employees to remain productive and focused.
2. Improved Reliability: Prevents disruptions in VoIP calls, video conferences, and VPN sessions, ensuring smooth, reliable communication.
3. Cost Efficiency: Rather than upgrading to more expensive internet lines, Dynamic QoS provides a cost-effective solution by better managing existing bandwidth.

“My firewall can do that.”

That’s a phrase we often hear from IT professionals when we talk about Bigleaf. 

If you’re referring to basic security and disaster recovery, it might be true, in part. After all, firewalls have been the first line of defense in a network for over a quarter-century. A mature network should have a built-in firewall to ensure a certain level of security and many do that also provide a level of redundant connectivity. 

Your setup may look like Stage 1 of the Internet Maturity Model: where you have a dual-wan firewall that allows you to have a second internet connection that can be activated when your primary connection goes down. When your primary connection fails, your business traffic needs to be moved, either manually or automatically, to the backup circuit. 

Seasoned IT pros can spend hours ensuring layers of redundancy are in place, as well as create Quality of Service rules that play nice with existing firewalls and add a level of application performance management. Rudimentary failover strategies, backup circuits, and QoS configurations like those are better than nothing. However, they can come with a variety of weaknesses which we’ll cover below. 

Check out this head-to-head comparison of your standard firewall vs. integrating Bigleaf into your tech stack alongside your existing firewall.

Firewall Limitations & Strengths

Your trusted firewall is important as it provides security and can provide the level of compliance you need. Some also help with connectivity. We’re not here to argue the security point. Instead, we want to make the case that Bigleaf allows organizations to achieve better connectivity and cloud application performance than firewalls.   

Your firewall – whether a Stateful Inspection, UTM, or an NGFW – or your amalgam of them needs to do more than just keep you compliant. They need to be a part of your infrastructure that keeps your business running smoothly in today’s digital landscape (where the cost of downtime & unusable uptime are rising to levels SMBs can’t afford while remaining competitive).

Round 1: Failover

Referencing Stage 1 of the Internet Maturity Model and tying into Round 1, when failover does happen, reconnecting all your business’ IP-specific internet traffic to the backup circuit is not instant. Your firewall can take seconds to minutes to failover. We’ve seen times ranging between 45 seconds to 8 minutes and some require a manual switch. However long it takes, performance is compromised, focus is lost. In the case of real-time VoIP calls, which drop the instant the connection drops, work completely stops. 

Basic Failover only provides support during outages; when the Internet is completely down. However, as seasoned IT professionals know, poor performance, brownouts, smaller outages, and more, disrupt business connectivity more often than complete outages. 

Bigleaf’s Same IP Address Failover seamlessly reroutes all traffic when there are outages and circuit disruptions, constantly keeping every business-critical application working as it should. With Bigleaf, when one of your circuits has any sort of outage, you don’t. Your IP address doesn’t change so your traffic automatically moves to your other circuit. Your VPN, VoIP call, and business-critical apps stay up! 

Yes, Bigleaf saves the call that would otherwise need to be reinitiated.

Round 2: Intelligent Traffic Management

Optimized cloud application performance is traditionally achieved with policies and manual configurations for QoS, traffic flow management across circuits, and failover. While some firewall solutions have tried to make some of this easier with preset selections, there is still a requirement that each policy is manually set. 

Bigleaf’s self-driving AI automatically identifies and prioritizes your application traffic, configures itself to optimize for your circuit conditions and traffic makeup, and instantly adapts to changes in real-time, improving call & video quality and app performance. 

With only a dual-WAN firewall solution in place, even if it advertised SD-WAN capabilities, an IT Manager would need to manually create or set rules for every app they know their users are using. Let’s explain using a real-world example: 

Firewall Only Example 

Given the state of SaaS adoption and different tools that SMBs use nowadays (and because you need to create rules with every app and every user with most dual-WAN firewalls), a company with only 18 employees could need to create over 400  rules for QoS alone. In other words, the simple solution requires more from your IT resources. 

With Bigleaf, circuit monitoring, load balancing, and traffic identification and prioritization happens automatically regardless of how many or what SaaS apps are being used by your team members. 

Winner: Bigleaf Networks

Round 3: Insights 

Lack of awareness of how your internet circuits are performing is a massive threat to an SMBs bottom line. If you don’t know a problem is happening, you can’t fix it. 

We briefly covered Stage 1 of the Internet Maturity Model – where you get a second circuit, plug it into your firewall, learn that an outage has occurred, then manually failover your traffic to the second line. It may seem “good enough” at first glance – it’s simple and low cost. What if we told you the low cost comes at a high one? 

Your firewall may let you know of outages at the time they happen, requiring you to act on the issue at that moment. However, you may not be aware of circuit and traffic performance issues that are consistently happening but seem minor or insignificant in your day-to-day application and internet performance. These issues can go unnoticed and cost you losses in revenue, productivity, user experience, reputation, and more. 

Visibility of your circuit and traffic performance across each of your ISP circuits delivers the insight you need when things change and need attention, and what to do to ensure reliable performance for each of your cloud applications and technologies. When it comes to reporting, Bigleaf edges out. Our Risk Monitoring feature goes above & beyond, taking the aggregate of the health and performance metrics we track and record to isolate critical events that can threaten your business continuity. Each risk alert is designed to give you a clear explanation and path to resolution so it can be resolved.
