In the realm of modern networking, the need for seamless access to network traffic and robust monitoring is undeniable. However, this requirement often clashes with the challenges of maintaining network performance, ensuring complete visibility, and scaling the infrastructure. To tackle these issues, Network TAPs and Network Packet Brokers (NPBs) come to the rescue.
Non-Intrusive Access to Network Traffic
Accessing network traffic is vital, but traditional methods like SPAN ports can disrupt network performance. SPAN ports introduce congestion, drop packets under load, and create single points of failure in your monitoring pipeline.
Network TAPs offer a fundamentally better approach. They passively copy traffic without causing congestion or failure. Your network's performance remains unscathed while TAPs ensure all packets are captured with zero interference to production traffic.
Achieving 100% Visibility
Effective monitoring requires 100% visibility at line rate. Without a centralized way to manage and distribute traffic, monitoring tools receive incomplete or irrelevant data, leaving dangerous blind spots in your security and performance posture.
Network Packet Brokers (NPBs) aggregate, filter, and distribute traffic to multiple monitoring tools simultaneously. They ensure that relevant data reaches each tool efficiently, guaranteeing complete visibility without overwhelming resources.
Scaling Without Complicating the Network
As networks expand, adding more monitoring tools can seem complex. Every new tool requires additional SPAN ports, cabling, and configuration changes that grow exponentially with network size.
NPBs simplify this process entirely. They facilitate easy scaling without altering the network structure, ensuring your monitoring capabilities grow alongside your network. Add tools on demand without touching production infrastructure.
Lower Total Cost of Ownership (TCO)
Traditional packet broker solutions rely on proprietary hardware and software bundles that lock you into a single vendor's pricing, upgrade cycle, and roadmap. This drives up long-term costs and limits flexibility.
The Disaggregated Open Packet Broker approach combines disaggregation and open standards, offering flexibility in hardware and software selection. By separating hardware from software, disaggregated packet brokers often lead to significant cost savings. You can choose cost-efficient hardware components and avoid proprietary hardware vendor lock-ins.
The Bottom Line
Network TAPs
Passive, lossless traffic copies without any risk to production.
Packet Brokers
Aggregate, filter, and deliver the right data to the right tools.
Effortless Scale
Grow monitoring independently without restructuring the network.
Open & Disaggregated
Break free from vendor lock-in with open packet broker architecture.
Network TAPs, NPBs, and the Disaggregated Open Packet Broker approach address the challenges of accessing network traffic, ensuring complete visibility, and scaling the infrastructure without introducing complexity. They are indispensable tools for optimizing network operations, enhancing security, and making informed decisions in our increasingly intricate network landscapes.
TAP and packet-broker questions, answered
What is the difference between a TAP and a packet broker?
A TAP copies traffic from a link. A packet broker aggregates, filters, replicates and distributes those copies to monitoring and security tools.
Does every TAP deployment need a packet broker?
No. A direct tool connection may suit a small use case. A broker becomes valuable when traffic, tools, speeds or delivery policies grow.
How can the visibility layer lose packets?
Oversubscribed outputs, bursts, tool limits, incorrect filters or insufficient packet-broker capacity can create loss. Monitor the monitoring path itself.
Why keep traffic access separate from production switching?
Independent access reduces reliance on switch resources and configuration, helping monitoring remain available during changes or incidents.
