Datacom Systems SS-2210BT-BT/SFP

Achieve Full-Duplex Visibility for Two (2) In-Line Network Links even with Single Interface Monitoring Solutions

The 2200 Series SINGLEstream™ Dual Gigabit (10/100/1000) Link Aggregation Tap from Datacom Systems provides a superior solution for 24x7 monitoring of Ethernet links.

While traditional network taps might enable full-duplex monitoring of all traffic on a network link, they transmit the data to the monitoring device (e.g. analyzer, IDS, probe) in two separate half-duplex streams. Not only does this require the monitoring device to have two network interface cards (NIC), it also requires that the device be capable of combining and processing both streams of data in order to monitor both sides of the conversation. Not all monitoring devices have that capability.

The 2200 Series SINGLEstream™ Dual 10/100/1000 Link Aggregation Tap faultlessly combines the four data streams, allowing any connected monitoring device to receive a full-duplex stream of data with one NIC.

The SINGLEstream™ SS-2200 Series Configurable Dual Link Aggregation TAP provide maximum flexibility allowing a choice of aggregation or non-aggregation of the bi-directional data on a single 10/100 or 1000Mb link.

• Manage TAP via management port or local serial port
• Any-to-Any architecture can send traffic to any port from any other port, eliminating the need for network managers to manage or change complex configurations of SPAN ports or move tools around their network.
• LINKprotect™ feature allows the relay failover circuit to close if either or both sides of the link go down
• “Any-to-Any” architecture on 2 ports allows the enduser to steer traffic as desired
• In-Line design eliminates contention for network access by freeing up SPAN/Mirror ports
• 24X7 access point for network monitoring and security tools

Features and Benefits:
 

Benefits:

• View entire full-duplex conversations even across redundant or load balanced links using single-interface monitoring tools
• Save money by reducing number of required tools or tool interfaces necessary to monitor all your data
• Decreased reliance on switch resources for network management visibility - eliminate SPAN port contention, oversubscription, and configuration errors
• After installation, deploy tools right away without impacting your production network
• Single point of deployment and remote management minimizes management expenses and reduces MTTR
• Automatic coverage of redundant network - One tool can monitor two networks

Features:

• Aggregation - Receive copies of multiple network links or channels into one stream for visibility into complete network conversations
• LINKprotect™ - Ensure automatic failover and recovery of redundant paths and routing protocols
• Regeneration - Send copies of traffic from the tap to multiple connected tools to share data sources
• Port Speeds from 10 to 1000MB; supports full duplex, half duplex, or auto-negotiate
• Stays invisible to the network for enhanced security
• Flexible traffic flow to monitoring tools - single-direction or bidirectional for traffic injection
• Dual Redundant Power ensures monitoring uptime

Solutions:

	Aggregation Monitoring full duplex network traffic from multiple sources is often a critical requirement for network monitoring applications. For example, in order to properly monitor redundant networks or a pair of load balanced links, network professionals might need to receive traffic simultaneously from two different network segments. In some cases, two network links may be bound together and operate as one logical network in order to improve bandwidth. In such an implementation, packets are distributed across two different physical links. Often, traffic transmits on one segment and receives on another. This makes network analysis and monitoring especially challenging. If an analyzer or monitoring device is put on only one physical link, it will not see the entire conversation. Also, while traditional taps might enable fullduplex monitoring of all traffic on a network link, they transmit the data to the connected monitoring device in two separate half-duplex streams (one for Tx and one for Rx). Not only does this require the monitoring device to have two network interface cards, it also requires that the device be capable of combining and processing both streams of data in order to monitor both sides of the conversation. Not all monitoring systems have the required hardware to aggregate traffic. The SINGLEstream™ Dual Link Aggregation Tap has two (2) network taps. Each tap combines both directions of a full duplex data stream and allows connected monitoring devices, even those with only one NIC, to receive a copy of all the data collected from both taps in a single trace file.
	LINKprotect ™ Many traditional taps prevent the operation of redundant routing and failover systems because they keep both sides of the network invisible to the other. The built-in LINKprotect™ feature eliminates this point of network failure by continuously monitoring both sides of the tapped network for link status. If one side of the tap loses link status, LINKprotect™ will close the other side of the link, so routers and switches can engage protocols to bypass the failed link. LINKprotect™ will also keep monitoring both sides of the link until repaired, where it can then automatically re-establish the primary link. Timers (polling and recovery) and link reestablishment settings (manual or auto) are all user-configurable on both sides of the link and provide a level of convenience and flexibility not previously available in copper Gigabit taps.
	Regeneration One-to-Many configurations replicate copies of identical network traffic to provide multiple tools monitoring access to the same links. In addition to eliminating contention for access to critical links, multiple tools can be connected to the same link for redundancy, testing, or advanced monitoring applications.
	Reliable and Easy to Use Unlike setting up operating systems and binding NICs, the SINGLEstream™ Link Aggregation Tap is simple to deploy, and every unit comes with dual redundant power supplies to ensure monitoring uptime.
