Net.Optics.10/100/1000.Copper.Port.Aggregators.provide.ultra-efcient.

access.to.critical.triple-speed.links.This.pioneering.technology.enables.any..

device.to.simultaneously.monitor.a.full-duplex.link.using.only.one.NIC.per.

monitoring.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.con-

nection.The.10/100/1000.Copper.Port.Aggregator.combines.and.regenerates.

these.streams,.sending.all.aggregated.data.out.two.passive.monitoring.ports

Buffering Prevents Lost Data

The.10/100/1000.Copper.Port.Aggregator.is.designed.to.handle.the.combined.

trafc.of.a.single.full-duplex.link.Normally,.the.trafc.should.be.below.the.

receiving.capacity.of.the.NIC

When.the.trafc.queue.exceeds.the.capacity.of.the.NIC,.the.Tap.buffers.the.

overow.of.up.to.one.gigabyte.of.data.for.both.sides.of.the.full-duplex.con-

nection.The.buffer.clears.automatically.when.the.trafc.volume.falls.below.

the.receiving.capacity.of.the.NIC.For.example,.if.there.is.a.trafc.burst.on.a.

1000.Mbps.network.port.and.a.monitoring.device.is.now.receiving.12.Gbps.

of.trafc,.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

Simple to Deploy

Net.Optics.10/100/1000.Copper.Port.Aggregator.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.exibility.and.ease-of-use.An.operating.

system.and.NICs.that.enable.binding.are.often.required.to.achieve.the.same.

functionality.as.the.10/100/1000.Copper.Port.Aggregator.In.contrast,.the.

10/100/1000.Copper.Port.Aggregator.requires.no.additional.components.or.

All ports that connect to the 10/100/1000 Copper Port Aggregator must be

congured for autonegotiation. The links will not function properly with

xed speed devices.
