10/100 Port Aggregator Tap  
Introduction  
Net.Optics.10/100.Dual.Port.Aggregator.Taps.with.Active.Response.provide.  
ultra-efficient access to critical links with the option to inject an active re-  
sponse.into.the.network .This.pioneering.technology.enables.any.two.devices.  
to.simultaneously.monitor.a.full-duplex.link.-.using.only.one.NIC.per.device  
Typically,.full-duplex.monitoring.with.a.network.tap.requires.two.NICs.(or.  
a.dual.channel.NIC).–.one.interface.for.each.side.of.the.tapped.full-duplex.  
connection .The.Dual.Port.Aggregator.Tap.combines.and.regenerates.these.  
streams,.sending.all.aggregated.data.out.two.separate.passive.monitoring.  
ports .The.best.part.of.this.innovation.is.the.onboard.memory.to.make.sure.  
traffic isn’t dropped during bursts.  
Response Ready  
When active responses to network events are required, the first monitoring  
port.can.be.changed.to.an.Active.Response.Port.using.a.hardware.switch .The.  
Active.Response.Port.buffers.and.transmits.into.the.network.link.any.type.  
of.Ethernet.packet,.from.a.simple.TCP.reset.to.ICMP.messages .The.Active.  
Response.Port.can.be.easily.switched.back.to.passive.monitoring.via.the.  
hardware.switch .  
The.combination.of.active.response.capability.and.passive.monitoring.in.  
the.Tap.reduces.the.number.of.devices.and.network.ports.required.for.active.  
response.functionality  
Buffering Prevents Lost Data  
The.Dual.Port.Aggregator.Tap.with.Active.Response.is.designed.to.handle.the.  
combined traffic of a single full-duplex link. Normally, the traffic should be  
below.the.receiving.capacity.of.the.NIC,.that.is,.less.than.10.or.100.Mbps  
When the traffic queue exceeds the capacity of the NIC, the Tap buffers the  
overflow of up to one megabyte per side of the full-duplex connection. For  
your convenience, the buffers clear automatically when the traffic volume falls  
below the receiving capacity of the NIC. For example, if there is a traffic burst  
and.a.tap.connected.to.a.100.Mbps.network.port.on.a.monitoring.device.is.  
now receiving 140 Mbps of traffic, the Tap buffers data until the burst is over.  
The.Tap.then.sends.the.buffered.data.to.the.monitoring.device.until.the.buffer.  
is.cleared

10/100 Port Aggregator Tap  
Simple to Deploy  
Net Optics’ Dual Port Aggregator Tap with Active Response is a simple plug-  
and-play.solution.addressing.the.fact.that.many.monitoring.systems,.including  
most.software.based.solutions,.only.offer.a.single.channel.NIC,.limiting.full-  
duplex.visibility .While.adding.a.second.NIC.can.help.maintain.data.integrity.  
and visibility, there is a tradeoff in flexibility and ease-of-use. An operating  
system.and.NICs.that.enable.binding.are.often.required.to.achieve.the.same.  
functionality.as.the.Dual.Port.Aggregator.Tap .In.contrast,.the.Dual.Port.  
Aggregator Tap requires no additional components or configuration on the  
monitoring.devices .  
All.network.and.monitoring.cables.required.for.plug-and-play.deployment.are.  
included.with.the.10/100BaseT.Dual.Port.Aggregator.Tap.w/Active.Response  
Better than Span Ports  
In the past, span ports were occasionally used to aggregate tapped traffic.  
However,.in.addition.to.other.shortcomings.of.span.port.monitoring,.span.  
ports.support.very.limited.buffering.and.can.simply.drop.data.during.bursts .  
The.generous.buffers.of.the.Dual.Port.Aggregator.Tap.prevent.data.loss.in.  
these.conditions  
Security and Visibility  
Without.an.IP.address,.monitoring.devices.are.isolated.from.the.network,.  
dramatically.reducing.their.exposure.to.attacks .However,.the.monitoring.  
device connected to the Tap still sees all full-duplex traffic as if it were in-line,  
including.Layer.1.and.Layer.2.errors  
Reliability  
For.extra.uptime.protection,.Net.Optics.Taps.offer.redundant.power.connec-  
tions .Should.the.primary.power.source.fail,.the.Tap.automatically.switches.  
to.the.backup.power.source .Power.LEDs.on.the.front.of.the.Tap.indicate.the.

10/100 Port Aggregator Tap  
Application Diagrams: Memory Operation  
All traffic that passes through the Tap is sent to the monitoring device NIC on  
a first-in, first-out basis, including traffic that is temporarily stored in memory.  
(If.two.packets.enter.at.the.same.time.then.one.packet.is.processed.while.the..  
other is stored briefly in memory, preventing collisions.)  
When there is a burst of data, traffic in excess of the NIC's capacity is sent to  
the.Tap's.memory .Up.to.one.megabyte.of.data.per.side.of.the.full-duplex..  
stream can be stored in memory. Memory continues to fill until its capacity is  
reached, or the burst ends – whichever comes first.  
In both cases, the Tap applies a first-in, first out procedure, processing stored  
data before new data from the link. If memory fills before the burst ends, the  
memory stays filled as the stored data is processed – data that leaves the buffer  
is immediately replaced. If the burst ends before the memory fills, memory  
clears.until.the.full.megabyte.of.capacity.is.available,.or.until.another.burst.in.

State 1: Side A + Side B is less than or equal to 100%  
of the NIC's receive capacity.  
Example: On a 100 Mbps link, Side A is at 30 Mbps and Side B is at 50 Mbps.  
The NIC receives 80 Mbps of traffic (80% utilization), so no memory is required  
for the monitoring device NIC to process all full-duplex traffic.

The Tap applies a first-in, first-out

in memory. As long as the NICʼs

Active Response Tap FAQs  
Q: What types of active responses are supported?  
A:.With.an.Active.Response.Dual.Port.Aggregator.Tap,.an.administrator.can.  
transmit.any.type.of.Ethernet.packet.back.into.the.original.link,.supporting.all.  
common.types.of.active.responses.generated.by.intrusion.detection.systems,.  
and.by.intrusion.prevention.systems.deployed.in.passive.mode .The.most.  
common response types are TCP resets, and firewall rule changes. While the  
Tap.can.support.both.types.of.responses,.we.advocate.extreme.caution.in.dy-  
namically updating firewall rules due to the risk of disabling network services.  
Because most firewalls are managed out-of-band, however, it is unlikely that  
the.Regeneration.Tap.will.be.part.of.a.rule.change.scenario .  
Q: How are collisions avoided when active responses are transmitted back  
into the original link?  
A: On each side of the full-duplex link, there is a small buffer for traffic ar-  
riving from the network, and another small buffer for active response traffic  
arriving from the monitoring device. Traffic is released from this buffer pair  
on a first-in, first-out basis. If both sides of the buffer are empty and a packet  
originating.from.the.monitoring.device.and.a.packet.originating.from.the.  
network.arrive.at.the.same.time,.priority.is.given.to.the.network.packet

10/100 Port Aggregator Tap  
Active Response Tap FAQs (Continued)  
Q: How much bandwidth is available on the Active Response Port?  
A:.The.average.amount.of.bandwidth.for.active.responses.is.determined.by.  
the.average.available.capacity.on.the.link .For.example,.on.a.100.Mbps.full-  
duplex.link,.if.transmission.from.device.A.to.device.B.averages.30.Mbps,.and.  
transmission.from.device.B.to.device.A.averages.at.50.Mbps,.then.there.is.an.  
average capacity on the first side for 70 Mbps, and on the second side for up  
to 50 Mbps of active response traffic.  
At.any.particular.point.in.time,.actual.capacity.is.determined.by.the.size.of.the.  
packets.being.transmitted.and.the.gap.between.these.packets .On.a.standard.  
link with 64-byte network and active response traffic, the capacity at any point  
in.time.will.be.very.close.to.the.average.capacity .(We.do.not.recommend.  
using the Tap on links with jumbo packets as these large – up to 9K – packets  
can fill the buffer and impact performance.)  
As the most common use for the Tap will be to inject TCP resets, which are  
standard.64-byte.packets,.it.is.unlikely.that.the.transmissions.from.either.side.  
of.the.Active.Response.Port.will.exceed.10.Mbps,.even.if.many.sessions.are.  
terminated.in.a.short.time.frame .In.our.internal.testing,.we.have.therefore.  
focused.on.Active.Response.Port.performance.at.up.to.10.Mbps  
Q: Does Active Response Port require the connected monitoring device to  
have an IP address?  
A:.Yes,.the.connected.monitoring.device.is.required.to.have.a.MAC.and.IP.  
address.when.the.Active.Response.Port.is.operating.in.active.mode .These.are.  
not.required.when.this.Port.is.set.to.passive.mode .The.Tap.itself.never.has.a.  
MAC.or.IP.address,.regardless.of.how.the.Active.Response.Port.is.set
