Net Optics xStream 40
Optimize Your IT Security Management and 40Gbps Network Traffic Monitoring with this Advanced Network Packet Broker
Net Optics xStream™ 40 product family provides comprehensive Network Packet Brokering for 40G networks, delivering filtering, aggregation, load-balancing, time stamping and more. Scalable and high-density, xStream 40 sets new standards in low latency and NPB. This advanced solution is engineered to provide high traffic monitoring and deep applications intelligence as networks soar to 40G. xStream 40’s ingenious load-balancing, aggregation, filtering capabilities let you share IPSs, firewalls and other tools across multiple independent network links, saving on costs and preventing tool oversubscription.
xStream 40 offers a unique cut-through architecture that enables time stamping of packets with nanosecond accuracy, plus xStream 40 supports packet manipulation options on all ports at line rate. With its amazing 1.28Tbps throughput, you can process more traffic faster while maximizing network performance and security.
This new generation of the xStream solution offers customers the advantages of 20 percent more filters and 2.6X higher port density, raising productivity, while saving costs and providing efficient additional options for navigating and managing, simplifying large-scale tasks, and sharing growing traffic loads among multiple tools. In addition, xStream 40 provides SDN ready capabilities.
Software Features Simplify Network Infrastructure Management
The xStream 40 solution is integral to monitoring today’s high-speed network traffic and controlling security risks. Today’s critical need to record and inspect all traffic as volume soars to 40G is pressuring companies to either purchase costly new 40G tools or risk oversubscription. Now xStream 40 solves this challenge and postpones capital outlay by optimizing current tool investment.
Advanced Architecture Designed for Network Monitoring Optimization
xStream 40’s data monitoring function delivers advanced architecture that uses SFP+/QSFP ports, as well as an integrated multi-speed flow distribution engine to perform distribution and load balancing of traffic from 10G and 40G links to multiple 1G, 10G, or 40G tools. The appliance also aggregates and filters traffic from multiple 1G and 10G links and distributes it to 1G, 10G, or 40G tools. Users simply plug in the appropriate SFP (1G), SFP+ (10G) or QSFP+ (40G) transceiver modules to match the interfaces of links and tools. The solution automatically performs the data rate and media type conversions—again reducing CAPEX and avoiding the disruption and learning curve that accompany new tools.
Any port can be used for either network connections or monitoring tools. In fact, by splitting cables into separate transmit and receive fibers, you can double the number of ports. TapFlow™ filtering technology sends each tool only traffic-of-interest for its particular purpose. The filtering engine processes traffic at full 10 Gbps line speeds, enabling you to select traffic by protocols, IP addresses, TCP/UDP ports, VLANs, and more.
xStream 40’s link aggregation and packet filtering function provides one-to-one, many-to-one, one-to-many, and many-to-many mappings of network links and Span ports to monitor ports. Traffic from any set of network links and Span ports can be aggregated into a single stream and copied to any monitor port. xStream 40 is a “Smart Filtering” appliance that directs traffic of interest to monitoring tools. Using xStream 40’s TapFlow filtering technology, each tool gets only the traffic needed for its particular purpose. TapFlow’s hardware filtering engine processes traffic at full 40/10 Gbps line speeds while filtering the traffic by protocol, IP address, TCP/UDP port, VLAN, and more.
xStream 40’s network monitoring load balancing function is a very cost-effective solution that provides exactly what is needed for these tools.
xStream 40 supports timestamping of packets on the fly at line rates with nanosecond accuracy—which is particularly important for high speed, low-latency trading environments. Using the PTPv2 (IEEE 1588) protocol, xStream 40 guarantees that timestamping remains accurate. The timestamp can be appended to packets on the fly with or without recalculation of the CRC.
High Availability with State Synchronization Ensures Network Monitoring Uptime
As the Network becomes critical for achieving business success, SLAs continue to demand near 100% uptime. xStream 40—like all three products in the xStream Family—delivers High Availability (HA) features to provide continuous monitoring visibility to your tools. State synchronization allows for two units to be deployed in a HA configuration to mirror all configuration changes. A configuration change (e.g., adding a filter) made on one xStream 40 is immediately mirrored to the other xStream 40, making sure that the two xStream 40s remain in sync all the time.Customers can deploy fully redundant security and monitoring tools in both in-line and out-of-band configurations—even if those tools were not designed with high availability features of their own.
More Advanced Software Capabilities Deliver More Control over Network Analysis and Management
The xStream 40 family’s software capabilities include existing Web UI, role-based access control, SNMP, Network Intelligence, and filter visualization functions, as well as SDN integration support, plus advanced device and policy management and CRM and AAA integration. Simplified MPLS Label Filtering streamlines identification of specific MPLS tags, filtering traffic with single or multiple tags and directing traffic smoothly to relevant tools. Port Rate Limiting prevents overburdening of tools such as IPSs/IDSs, DLPs and firewalls, limiting data volumes to what a tool can reliably handle.
