Business Needs Vs. Network Performance: Critical Challenges Facing Network Managers

Networking is getting tougher. The networks should provide a growing range of services, from ERP, CRM and e-mail to VoIP services and web applications, each has its own idiosyncrasies, and mentioned requirements. Each new service introduced onto the network contends for available resources with any other service, impacting the ability of the network to support business.Meanwhile, the same network is constantly evolving. New locations are added - some of which may be in another country or another continent. Equipment is updated and / or re-configured. New management and / or security tools may affect the performance of such services. Decisions regarding the consolidation of data centers and business reorganization also affect the network in different ways. All this makes the network a highly dynamic environment, where even small changes can have a major, unforeseen impact on application performance and business users expect this complex environment availability.Yet to be as reliable as electricity - not despite the fact that the budgets of the network are increased in proportion to these growing challenges. Sun network managers can not simply over-supply of network infrastructure to ensure that each service has all it needs banda. Moreover, during provisioning may not solve the problem and / or to ensure the necessary level of performance.That 's because the network operators are faced with many challenges, including: 1) Identification of potential network performance issues lifecycleIdeally in the early stages of development, the impact of the network on a new application or service must be treated from the beginning of the development process - when potential problems are much easier and less expensive to repair. Unfortunately, this is rarely the case. Problems with application to "network capabilities" are typically discovered only after his roll-out into the production starts. At that point the design is usually too late to make significant changes of uses. So the problem is pushed on the shoulders of the networking team. That's why, in '05, the intelligent network operators want to focus on nipping these problems in bud.2) Validate new or modified applications and infrastructure before it is distributed in productionAs network becomes more complex and more critical day by day - management activities, risks related to network performance, associated with application and infrastructure change continue to grow. In fact, some of the worst business interruptions that companies have historically experienced, were not the result of unexpected equipment failures. Have the unintended consequence of a change. Teams then change the network must implement best management practices in '05 preventDefault them from having to put out fires that they accidentally started themselves.3) Improved troubleshooting intermittent / transient network problemsOne the most frustrating things for a network operator is a problem that continues to disappear before it can be properly understood and solved. However, as the tolerance of the business network interruptions continues to drop, these intermittent problems will become a management problem bigger. So this year, the management team of the network they need to develop more effective methods for capturing transient network conditions and discovering the causes of these problems.4) accelerated time-effectiveness of new and / or updating applications When C-level executives decide to invest in new applications and services, they want to see those investments pay off quickly. That's why the slow, staged the production roll-out of the past will not cut it anymore. Instead, networking teams must be able to quickly deploy new applications across the enterprise. This can only happen if caution and uncertainty about the actual behavior of these applications into production is replaced by trust and confidence in the '05 .5) smarter planning for business growth and support of network operators must constantly deal with change. They have my way of discouraging the use of the net increase is the application performance. They must decide how to design the best network to support business expansion, reorganization or mergers and acquisitions. However, they can only do so if they have an effective means to carry out tasks of capacity planning and evaluating a full range of "what-if" scenarios. Scenarios research is so important for the formulation of realistic plans that can ensure business continuity in a variety of conditions.Looking can these challenges, it quickly becomes apparent that the conventional generation of network management tools are no longer sufficient alone for the teams of today's network. These tools are ideal for monitoring the production network and the discovery of some types of problems - but do not allow network managers to validate new technologies and applications before they are distributed on the production network. They also force network managers to troubleshoot problems that should have been addressed in the application tools design.Conventional are not very useful for troubleshooting intermittent network problems and / or transient, since they do not provide a means to reconstruct and analyze the intermittent conditions examined. Neither help accelerate production roll-outs, facilitate experimentation with "what-if" scenarios, and the formulation of support plans.So emergency network on what is overworked, the resources necessary network manager to do? The answer is to look at network modeling technologies. These technologies provide an environment where new applications, technologies and strategies for problem-solving and can safely be carefully evaluated. Why allow the behavior of network applications to be fully validated before being deployed in production, these technologies also empower network managers to run faster, glitch-free roll-out. Furthermore, modeling technologies are the only ones who can provide insight into any number of "what-if" scenarios - so network managers can make plans for growth, corporate re-structuring and / or disaster recovery "empirical "modeling solutions offer today's team of network management. In particular, excellent commercial value, because of their accuracy and the relative ease of implementation. This accuracy and simplicity is obtained by performing the real-world applications in respect of a model that uses captured from the production conditions. The result is a clear understanding of user experience well before deployment.To learn more, visit http://www.shunra.com.

[EXTRACT] Networking is getting tougher. The networks should provide a growing range of services from ERP, CRM and e-mail, VoIP and Web services applications, each of which has its own characteristics and needs. Each new service introduced onto the network contends for available resources with any other services that affect the system's ability to business.Meanwhile to support the network itself is changing. New sites are added - some of which may be in another country or another continent. Equipment will be updated and / or reconfigured. New management and / or security tools may affect the performance of the service. Decisions regarding the consolidation of data centers and business reorganization also affects the network in different ways. All this makes the network a highly dynamic environment, they expect even availability.Yet subtle changes is an important, unanticipated impacts on the performance of applications and business users to ensure that this complex environment to be as reliable as the electricity could have - despite the fact that budgets are not satisfied network increased in relation to these growing challenges. Thus, network managers can not simply over-supply of network infrastructure to ensure each service has the bandwidth it needs. Furthermore, the arrangement does not solve the problem once and / or provide the necessary level of performance.That why network managers face many challenges, including: 1) identify potential network performance issues early lifecycleIdeally development, the impact of the network for a new application or service should be addressed early in the process of development - when potential problems are much easier and less expensive to repair. Unfortunately this is rarely the case. Problems with the application of "networking" are usually discovered, is initiated only after its implementation in a production environment. At this point, it's usually too late to make significant changes in application design. So the problem is pushed on the shoulders of the networking team. Therefore, in '05, the intelligent network operators focus on nipping these problems in bud.2) validation of new or modified applications and infrastructure, before being deployed in productionAs network becomes more complex and critical for the daily management company are risks of network performance associated with changes in applications and related infrastructure to rise. In fact, some of the worst business interruptions that companies have historically experienced, not the result of unexpected equipment failures. They had the unexpected consequence of a planned change. Teams must then network, best practices on managing change in '05, which prevent them from having to clear the fire that started by accident themselves.3) Improved troubleshooting intermittent / transient network of the most frustrating things for a problemsOne network operator it is a problem that continues to disappear before they can be properly understood and resolved. However, since the activity of tolerance for network interruptions continues to drop, these intermittent problems will be a serious management problem. So this year, the management team of the network of more effective methods for the detection of transient network conditions and discovering the causes of these developments problems.4) accelerated time-to-effectiveness of new and / or updating applications when C-level managers decide to invest in new applications and services that they want to see those investments pay off quickly. This is the reason why the slow, staged rollout of the past will no longer keep pace. Instead, networking teams to be able to make new applications across the enterprise. This can only occur when care and uncertainty about the actual behavior of these applications in the production of trust and security will be replaced in '05 0.5) smarter planning for growth and support of network manager processes company they are dealing with constantly changing. You must determine how to increase network utilization affects performance. You must decide how best to build the network to support business expansion, reorganization or mergers and acquisitions. However, they can only do so if they have an effective means of implementing the tasks of capacity planning and evaluation of a full range of "what-if" scenarios. These scenarios are also crucial for the formulation of realistic plans, business continuity is possible under a variety of conditions.Looking to these challenges to ensure that it quickly becomes clear that conventional production network management tools by themselves are no longer sufficient for today's network team. These tools are ideal for monitoring the production and power to detect certain types of problems - but they do not allow network operators to validate new technologies and applications before they are in use on the production network. They also force network managers to examine the issues that should design.Conventional had to use tools to solve is not very useful for troubleshooting intermittent network problems and / or temporary, or because they have no means of reconstruction and analysis such conditions intermittent. Nor, accelerate production roll-outs, facilitate experimentation with "what-if" scenarios, or support for the formulation of network contingency plans.So What is a revised version, under-funded network manager to do? The answer is looking at network modeling technologies. These technologies offer an environment where new applications, technologies and strategies to solve problems can be evaluated with care and attention. Why use the behavior of the network are fully validated before being allowed in a distributed production environment, these technologies allow network operators to deliver better performance, glitch-free roll-out. Furthermore, modeling technologies can be an unprecedented look at any number of "what-if" scenarios to provide -. Thus, network managers can make plans for growth, corporate re-structuring and / or disaster recovery "Empirical" modeling solutions offer network management team today particularly excellent value for the precision and relative ease of management. This precision and ease of use is to run the actual applications against a model that uses captured conditions obtained from the production environment. The result is a clear understanding of user experience on deployment.To learn more, visit http://www.shunra.com.
