CASE STUDY: TRADING UP TO SWITCHES
In 1996, Chase's trading-floor network was in trouble. Traffic was so
slow that traders joked they could hail a cab in less time than it
took to download files. Two years and a big trade-up later, their
hierarchical switched network is paying big dividends:

VSAT SERVICES: KEEPING AN EYE ON THE SKY
Net managers know that when it comes to VSAT services, there's a lot
that's up in the air. To bring it all down to earth, we issued an RFP
for our own international network and nine operators responded. Among
our findings? Price isn't always an indicator of coverage - or
quality.

REGIONAL INTERNET BACKBONES: DIRECT CONNECTIONS
Internet detours add delays. Until recently Asia-Pacific 'Net traffic
went the long way, making transpacific trips to the U.S. just to make
regional connections. Now new backbones are being built that will
offer a local exchange. Time to bone up on the benefits:

GIGABIT CABLING: THE COPPER STOPPER?
Can new cabling systems carry gigabit data? Vendors says yes, but with
a Category 6 spec months (or more) away, corporate networkers have no
way of knowing for sure. What's more, there's evidence that cable
vendors are cutting Cat 6 margins dangerously thin. That's why Data
Comm is advising net managers to go slow on high-speed copper:

VOICE OVER IP SERVICES: THE SOUND DECISION
Talk is cheap--and IP telephony is making it a lot cheaper, especially
when net managers can bypass pricey international circuits. Corporate
networkers interested in savings need to give voice over IP a close
look and check out the trade-offs in coverage and quality:

PACKET OVER SONET: RINGING UP SPEED
Get ready for a high-speed WAN transport that leaves LAN traffic in
its native format--and ATM in the dust. POS (packet over Sonet) is
faster, more reliable, and makes better use of Sonet capacity, since
there's no ATM overhead:

MONITORING INTRANET PERFORMANCE: TIME TO STRATEGIZE
Intranets evolve piece-by-piece with technical choices arising from
urgency, not strategy. Net managers need to plan intranet growth to
avoid business risk. Here's how, in just four simple steps:
