Simena Packet Flow Switch

Packet Flow Switch 1524 Data Sheet Packet Flow Switch 2000 Data Sheet With many 10GE/1GE wire speed ports, Packet Flow Switch (PFS), acting as a aggregation and filtering switch, allows users to collect packets from many sources and send them to various devices.

Through it's web based user interface, it is very easy to create any-to-many, many-to-many and many-to-any connections. For example, as a traffic aggregation tool, the Packet Flow Switch can be used to collect packets from sources such as routers, switches, and load balancers. These packets can then be sent to various traffic analyzers, loggers or monitoring systems.

Applications

· Load balancing heavy traffic to multiple monitoring tools

· Sharing expensive network tools among many SPAN ports and TAPs

· Multicasting critical traffic to multiple security devices

· Bridging traffic between expensive 10G and multiple 1G ports

· Layer 1-7 filtering and packet slicing to reduce the chatty SPAN/TAP traffic

· Dynamically creating aggregating and regenerating TAPs with media and speed conversion

Features

· Industry's lowest latency

· 10GE full-duplex wire speed

· Layer 1-7 filtering

· In-line bidirectional or unidirectional packet capture

· Packet slicing

· Tagging packet with port numbers

· Media conversion

· Matrix switching

· Aggregating, non-aggregating and regenerating TAPs

· Active or passive by-pass failover

· In-line wire speed packet capture

· All ports can be used for any function

· Optional software features such as packet generation, network emulation, network measurements

· Comes in two unique models; PFS1524 for 10GE wire speed and PFS2000 for 1 GE wire speed performance

Low Latency

Simena's Packet Flow Switches have very low latency to optimize the timing of monitoring traffic. For example, PFS1524 model has the industry's lowest latency between any port at any utilization.

Wire Speed

Packet Flow Switches provides any to any connection at wire speed for any packet size. PFS1524 has 10GE full duplex wire speed under any utilization, meanwhile PFS2000 model has 1GE wire speed.

Web Based GUI

Simena's Packet Flow Switches are managed by easy to learn and use web based GUI which provides very intuitive user interface with mouse over hints to utilize the system very easily.

Packet Slicing

Packet slicing feature allows users to forward packets with headers only by striping the payload or any portion of the packet to eliminate overloading of monitoring tools. Users can specify to slice packets from 64 to 4096 bytes.

Port Tagging

Port tagging feature allows marking each monitored packets to be tagged with unique numbers such as the port numbers they come from. This way the monitoring system can identify each packet based on their physical source.

XML Based Filters

Simena's extensive packet filtering allows users the capability to pick and choose which packets to be forwarded. Packet Flow Switch has extensive XML based packet filters for Ethernet, IP, IPV6, TCP and UDP packet filtering and other protocols.Filters can be logically combined with AND, OR and NOT operators to create complex filter sets.

XML based packet filtering allows users to define any type of packet filter in an XML file. Newly defined filters can be used instantly in the web based filters page. This filtering method provides capability of easily defining packet filters for new implementations such as IPTV, iSCSI, IPV6, 4G.

In addition, Custom Filters provides filtering anywhere inside the packet including payload for deep packet inspection.

XML based filters can easily be created by editing the configuration file. Below shows a iSCSI filter for filtering iSCSI messages:

<header name="iSCSI">
<label>iSCSI packets</label>
<filter>tcp[0:2] = 3260</filter>
<label>iSCSI opcode</label>

<filter>tcp[32] amp; 0x3fff = $iscsi_opcode</filter>

Packet Capture

Simena's PFS is also capable of capturing packets in-line while providing any-to-any connections. PFS captures high speed data packets and saves them in PCAP format for future analysis. Capturing can be selective by using packet filters and by specifying number of packet to capture. For wire speed large amount of packet capture a dedicated Simena Traffic Generator with Capture&Replay feature is recommended.
