How network managers deal with network slowdowns affecting application performance

Over two-thirds of network managers spend at least 25 days per year determining the cause of network slowdowns affecting application performance.

The worldwide survey of 600 CIOs, network engineers and IT managers found solving application issues takes the largest amount of time for network professionals. Thirty per cent of network professionals spend 26-50 days annually replicating network issues, while 41 per cent spend up to 25 days per year attempting to replicate network problems, according to the research from Network Instruments.

The biggest problem with network issues affecting application performance was bandwidth consumption. Over one third cited bandwidth consumption issues as the key offender, while 32% reported application latency and delay issues as the second most common problem. This can be a major problem for businesses deployong converged networks.

"Over the last two years, while IT teams purchased new tools to optimise applications and traffic, the amount of time spent troubleshooting performance problems increased," said Ian Cummins, vice-president of EMEA for Network Instruments.

The survey also found 66% of organisations have implemented or are planning to implement Voice over Internet Protocol (VoIP) within the next 12 months. Quality of service and the impact of VoIP on other applications proved to be the largest VoIP concerns for network professionals.

Multi protocol label switching (MPLS) is another area of growth. Migration to MPLS networks is in the early stages of adoption according to the research. The survey found that 35% of respondents will have migrated to MPLS networks in the next year, while 55% do not intend to migrate to MPLS.
