Testing and Trouble-shooting Challenges in
Converged Businesses and Data Centers
bull Increasing complexity of testing at all levels ndash cabling network equipmentnetwork link performance network applications and services
bull Low work-force skill level (high attrition unskilled low-cost staff)
bull Insufficient budget to cater for technician training needs
bull Finger-pointing instead of focused troubleshooting (network guys thinks itscabling issue cable guy thinks network is broken)
bull Increasingly impatient customer who has high dependency on IT infrastructure
bull Does this sound familiar

How Cross Layer Testing Helps
Testing Challenge Cross-layer Handheld Tester
Increasing complexity of testing Integrated testing of cabling network
connectivity network link performance
server performance VoIP
Low work-force skill level Easy user interface ldquono need to do PhD
to solve problemsrdquo
Consistent look-and-feel across test
applications (cabling network testing)Low budgets Minimizes cost of ownership
-Replace many test instruments with one-Scalability pay for it when you need it
Difficulty of root-cause finding Automated troubleshooting steps
(network Autotest)Problem can be anywhere you needonly one instrument to find

Cross-layer Testing Advantage
One Tester does job of two
Combined network testing andcable testing
Cost is almost half that of two ormore independent testers

Testing and Trouble-shooting Challenges in
Converged Businesses and Data Centers
bull Increasing complexity of testing at all levels ndash cabling network equipmentnetwork link performance network applications and services
bull Low work-force skill level (high attrition unskilled low-cost staff)
bull Insufficient budget to cater for technician training needs
bull Finger-pointing instead of focused troubleshooting (network guys thinks itscabling issue cable guy thinks network is broken)
bull Increasingly impatient customer who has high dependency on IT infrastructure
bull Does this sound familiar

How Cross Layer Testing Helps
Testing Challenge Cross-layer Handheld Tester
Increasing complexity of testing Integrated testing of cabling network
connectivity network link performance
server performance VoIP
Low work-force skill level Easy user interface ldquono need to do PhD
to solve problemsrdquo
Consistent look-and-feel across test
applications (cabling network testing)Low budgets Minimizes cost of ownership
-Replace many test instruments with one-Scalability pay for it when you need it
Difficulty of root-cause finding Automated troubleshooting steps
(network Autotest)Problem can be anywhere you needonly one instrument to find

Testing and Trouble-shooting Challenges in
Converged Businesses and Data Centers
bull Increasing complexity of testing at all levels ndash cabling network equipmentnetwork link performance network applications and services
bull Low work-force skill level (high attrition unskilled low-cost staff)
bull Insufficient budget to cater for technician training needs
bull Finger-pointing instead of focused troubleshooting (network guys thinks itscabling issue cable guy thinks network is broken)
bull Increasingly impatient customer who has high dependency on IT infrastructure
bull Does this sound familiar

Testing and Trouble-shooting Challenges in
Converged Businesses and Data Centers
bull Increasing complexity of testing at all levels ndash cabling network equipmentnetwork link performance network applications and services
bull Low work-force skill level (high attrition unskilled low-cost staff)
bull Insufficient budget to cater for technician training needs
bull Finger-pointing instead of focused troubleshooting (network guys thinks itscabling issue cable guy thinks network is broken)
bull Increasingly impatient customer who has high dependency on IT infrastructure
bull Does this sound familiar

How Cross Layer Testing Helps
Testing Challenge Cross-layer Handheld Tester
Increasing complexity of testing Integrated testing of cabling network
connectivity network link performance
server performance VoIP
Low work-force skill level Easy user interface ldquono need to do PhD
to solve problemsrdquo
Consistent look-and-feel across test
applications (cabling network testing)Low budgets Minimizes cost of ownership
-Replace many test instruments with one-Scalability pay for it when you need it
Difficulty of root-cause finding Automated troubleshooting steps
(network Autotest)Problem can be anywhere you needonly one instrument to find

How Cross Layer Testing Helps
Testing Challenge Cross-layer Handheld Tester
Increasing complexity of testing Integrated testing of cabling network
connectivity network link performance
server performance VoIP
Low work-force skill level Easy user interface ldquono need to do PhD
to solve problemsrdquo
Consistent look-and-feel across test
applications (cabling network testing)Low budgets Minimizes cost of ownership
-Replace many test instruments with one-Scalability pay for it when you need it
Difficulty of root-cause finding Automated troubleshooting steps
(network Autotest)Problem can be anywhere you needonly one instrument to find

Cross-layer Testing Advantage
One Tester does job of two
Combined network testing andcable testing
Cost is almost half that of two ormore independent testers

Networking applications evolve faster
than technicians can learn
Simplified troubleshooting with easy to
follow performance scale
One symptom may have many possibleroot causes
Ability to automate problem finding andthen drilling down to root cause finding
How to validate link performance from
service provider
Network link performance benchmarking
(traffic generation RFC 2544 tests)
Under-performing Network links in theserver farms directly translate to revenueloss
Network link performance benchmarking(traffic generation RFC 2544 tests)
VoIP under-performance is difficult to fix Quantify audio quality and find reason
behind poor quality
