Maintain your company’s monitoring solution when the network’s bandwidth requirements change.
As networks grow and expand over time, so do their bandwidth requirements. Upgrading the available bandwidth on a network can be an expensive endeavor since not only the network, but also the monitoring and security tools, must be upgraded. The load balancing capabilities of Network Packet Brokers make it possible to use lower speed tools to monitor high-speed network links and can help retain your investment in a monitoring solution.
Why do I need load balancing?
Higher speed traffic needs to be distributed across several lower speed monitoring devices. Load balancing can evenly divide traffic among these devices by separating it based on a set of criteria Forcing traffic through a single device can lead to oversubscription and, in turn, dropped packets. Load balancing mitigates the risk of oversubscription, helping to prevent data loss and potential security threats due to dropped packets.
Here are three ways that network packet brokers with load balancing create flexible options for monitoring your network:
• Custom traffic settings. Load balancing criteria determine how traffic is split between monitoring devices and is dynamically customizable. By selecting a variety of fields in a network packet, load balancing can be optimized for unique traffic types. For example, network traffic going to different servers can be distributed across separate monitoring ports, or traffic could be sorted by application.
• Two-way monitoring. Multi-port network packet brokers can be used to monitor two-way traffic on the network, sending both streams to the monitoring device in order to fully analyze communications. This feature makes sessions “sticky” to specific monitoring tools, allowing them to watch the full duplex, two-way conversation.
• Redundancy. When using load balancing to monitor your traffic, if one monitoring device fails, or the device needs to be taken offline for software updates, traffic is redistributed to a redundant device. If a failed device is repaired, you can decide whether the repaired device will again receive traffic.
As the number of devices and servers connected to your network continues to grow, your network’s bandwidth requirements are bound to change. Rather than abandoning your current monitoring solution, consider the flexible capabilities of load balancing network packet brokers.
