GET THE MOST OUT OF YOUR PACKET BROKER: SEEKING EFFICIENCY
One of the biggest inhibitors of pervasive network security is lack of visibility into the underlying infrastructure. Increased visibility provides operators from network behavior and anomalies. The achievement of such a goal requires Network packet brokers (NPBs). NPBs enable organizations to use their monitoring tools more efficiently, to centralize traffic monitoring and security functions and create centers of IT expertise, and to share tools and traffic access between groups. Most NPBs also provide functionality that helps extend the return on investment (ROI) on existing network monitoring, security and acceleration tool while also helping justify more expensive higher throughput monitoring and security tool purchases. By providing such a functionality, NPBs simplify deployment and management of security and monitoring tools while maximizing the ROI customers can achieve from these tools while helping reduce associated CAPEX, and the OPEX for managing and maintaining them.Therefore, Cost Effective Packet Broker with Distribution and Filtering, preferably with Low Latency, would be most keenly adopted by carrier operators worldwide. An ideal set of basic packet brokers provide a combination of functionality that may include aggregating monitored traffic from multiple links, traffic filtering and grooming, traffic regenerating and load balancing actionable traffic to multiple tools, pre-filtering traffic to offload tools, and directing traffic according to intelligent one-to-one and many-to-many port mappings The LTV8121 handles aggregation multiple packet stream, inputs them into one larger stream. For example, five 1Gb links can be aggregated into a single 10Gb link. Alternately, the reverse also will work, where a single 10Gb link would be fed into multiple 1Gb connections. The destination would be a monitoring tool with the proper interface. Distributing traffic load per device by sending it to different probes or appliances in order to scale the monitoring, or to provide redundancy in the monitoring technology.
However, the deployment of NBPs are limited to the fact that the cost of such devices is affected by the efficiency it can bring for the increased ROI, This limitation is enlarged when the deployment of such equipment is at network edge, where numerous of numbers of ports are required for processing 1G Ethernet data traffic. The Luxar Luxscope™ LTV8121 packet broker features 48 X 1GE link and 4 X 10GE link and is capable of many-to-many port mapping, with a configuration command line interface for real-time adjustments of packet flow, including port mapping and paths. The LTV8121 also filters packets based on the characteristics found in the packet headers with ACL rules, allowing filtering of OSI Layers 2 through 4. Upgraded version of LTV8121 which is equipped with DPI functionality also allows packet slicing and deduplication, which allows a subset of the full packet data to be passed to the monitoring device, further increasing the efficiency of network and associated tools, DPI enabled LTV8121 also allows the filtering and routing of packets based on data characteristics in the header or payload, and support for filtering on OSI Layers 2 through 7.
Thanks to its advance chipset, the LTV8121 has a feature allowing Insertion of hardware-based time stamps that can be used by the monitoring tools to provide more accurate measurements. These can change the accuracy of the packet time stamp from milliseconds to microseconds, enabling more granular time measurement. As Few NPBs also offer load balancing across multiple tool ports, filtering on patterns in packet payloads, and converting media and data rates so tools can be used to monitor traffic from dissimilar links.
The effective any to any crosslink makes it easy for LTV8121 to optimize and deliver traffic from various ports toward any of the tools needed using the When a number of monitoring tools are connected to the NPBs tool ports, copies of traffic from any of the network ports can be optimized and delivered to any of the tools using the NPB’s CLI, GUI or central management interface. The high density and flexible 1RU design of the LTV8121 enables it to offering a very versatile solution for 10GE and 1GE links conversion to seamlessly work with your current tools among groups and help extend the ROI from existing tools. Also, due to their high port densities and modular form factors compared to discreet Taps, The LTV8121 can save considerable rack space and power, and can have a lower price per port while allowing you to future-proof your investments. In a nut shell, not all NPBs are created equal.
