Report on Network management

Introduction of Network management

Efficient network management is often facing challenges in the real world. Challenges faced by network management includes care and size of the internet. The network request for efficient tools is allowed to access the internal and external network. Since early 1986 organisations have realised that that the use of the internet and mobile devices is an efficient way to expand the existing business. Network management is a process that includes controlling and monitoring of the network and ensure that all the functional areas are working. The operational areas of network management include users, network administration, functional areas, configuration management, account management, security management, and performance management. The network management architecture comprises of centralised manager that focuses on all the memory devices, computer systems and network devices. The central network management station checks the variables of Android device is variable and manager function of each device in the network (Wallin, Ahlund, & Nordlander, 2012).  All the manage devices store information database that is called a management information base. An agent software module is the first software that compiles all the information provided in the network system, database, and store the information in the network management station. There is a number of issues and challenges faced by network management architecture therefore the management of Corporate network is becoming harder and harder with increasing heterogeneity and complexity. The serious issue faced by the network is connectivity failure and other fault management problems. Some other issues included delay in the services and packet losses in the network. Both of these problems result in performance degradation (Rao, 2011).  With the rapid advancement of Technology, Innovative Strategies and devices are fabricated to deal with network management. To reduce the issues regarding network management the best strategy is to reduce network Administration and to make it as simple as possible. Some moderate skills include knowledge of Technologies particularly web technologies, capacity planning, asynchronous transfer mode of data, and Integrated digital network domains. The aim of the present report is to deal with issues faced during network management and hypothetical solutions to resolve these issues (Gupta & Szymanski, 2003).  The key challenges faced by the network manager is to maximize the productivity benefits without increasing network complexity and cost. The total cost of the network includes implementation, annual maintenance, support cost staff members to the trainer and other considerations of the business network. All these issues are centralised on the architecture of the network.

Network management challenges

Network management is critical for the success of a business organization. In the organizations, managerial staff develop several strategies and plans to support network management system with the aim to control challenges. Although, challenges can be crucial for the success of an organization. Some quite common network management challenges are discussed below which are required to be controlled and managed by the managerial staff to ensure organizational success (Desai, Lusk, Bradshaw, & R. Evard, 2003). Current challenge faced by network manager is to improve productivity and Critical network system demonstrate the way of managing the network solutions and tools. It is important to keep the network ownership at low cost the increased cost could lead to an increase in images provided by the user to the users. Definitions of network management tools and their solution are making a path for mixing productivity. Some examples of network management include HP openview Cisco work, CA Unicenter, IBM Tivoli, and Novell sensor. All of these solutions are centralised on the architecture of the network manager. Tools of network management have advanced different span for the heterogeneous networks, equipment in a complex communication environment. This is ko the network is predominantly managed by the least amount of time and cost (Vesalainen, Valkokari, & Hellström, 2017).  This system is designed to recognize all the cisco devices and responses everywhere at extremely stressful conditions. The management system must enable the uses to have improved performance and availability. The top 6 challenges faced by network management are listed below,

1.      Poor network performance is due to high-speed communication issues.  In this type of issue, no Software and Hardware is involved.

2.      Network security is another top challenge can be affected due to service attacks. There is a number of tools that can be used to improve network security. These multiple tools require monitoring and Management.

3.      Configuration management is another issue that needs the support of traditional IT application.  It is difficult to keep the Firewall update and the policies manually to reduce the error inconsistencies.

4.      The cost of network services is high particularly for conventional business services, but companies require a level of network quality.

5.      If the network remains the same all the other challenges will be different. It depends upon a number of devices attached to the network and connection type. Vendor login with another reasonable problem because the vendor can find out and integrate the multiple solutions place in the network (Strassner & Strassner, 2004).

1. Poor integration of Network System:

Poor integration of network systems is a highly influencing challenge for organizations. The network system of the organization enables the workforce and managerial staff member to interact with each other through digital media and network. Through an integrated network system, managerial staff can communicate and share instructions regarding work and projects with their subordinates and team members (Arpege Group, 2012). While poor network integration will cause problems for them to contact each relevant person and share information regarding the project or task. However, there are also chances that because of this poor integration system managers may fail to deliver information to all relevant team members in-time and a situation of ambiguity causes conflict later. However, poor integration system of the network between departments will also cause challenges for inter-department communication (Desai, Lusk, Bradshaw, & R. Evard, 2003).

2. Security Threats  of Network management

Security threats are quite common in organizations. Inappropriate network management can cause security threats regarding data breaches and third-party access. Moreover, poor management of the network system will also provide an opportunity for hackers to get access in the linked systems with organizational network and manipulate or delete important information.

3. Inappropriate and insufficient Monitoring System

Sometimes organizations fail to provide an appropriate monitoring system for network management, as a result, this, challenges increase for organizational management.

4. Failure to deploy Network of Network management

Failure to deploy is usually caused by the cost-control strategies and complexity of network management system. Failure to deploy causes problems for user-friendliness and configuration of the network system (Desai, Lusk, Bradshaw, & R. Evard, 2003).How to improve of Network management

 From the overall perspective the discussion considered network management and explain current problems at big Telecom operators. With the development of Technology, the things are changing and operator environment is also changing. In other words, it is important to cope with the current problems and to improve the quality of the network system in an organization. Problem analysis considering the present work deal with the effectiveness and quality of service centric management, dynamic management, managing network along with management of interfaces, knowledge management, automation between all the systems of all network layers (Vesalainen, Valkokari, & Hellström, 2017).  Considering the broader context to the network management has three types of users. The network operator earn money on their services. Network service users are consumers and business who pay for the services provided to them. The network administrator is the staff member of network operation center that work on the particular network model. All the three types of users are benefited by management solution. Operators increase their profits and benefits from the services while administrators streamline their workload (Vesalainen, Valkokari, & Hellström, 2017). The solutions of network management empower network operators to have Quality Services, management of building and uses, and management of better services provided to the customers. Network management is a centralized function that put operator is as a control and use management solution. Operators in the network management are under pressure to reduce operating cost of network (Strassner & Strassner, 2004).

In the network management system, the operators are under pressure to reduce the network cost and to provide better control of network with the increasing speed. The main requirements of the network management include automated, effective and managed solutions. In order to explore the solution different Telecom network management centers are analyzed (Wallin, Ahlund, & Nordlander, 2012). These analyses identified 6 challenges faced by big Telecom operators including excessive alarms, constant changes, Complex services structure, customer interaction, cuts in operating cost, difficult interface integration. The direct and diverse ecosystem and equipment make the Managing interface more integrable, the excessive alarm issue is a simple problem that reduce by using automatic trouble ticketing system (Desai, Lusk, Bradshaw, & R. Evard, 2003). This process is simple network management process based upon alarm management information bases with different conditions of time consuming and specific equipment requirements. In the constant change network changes with and upgrade with changing network Management Solutions and operators. The dynamic nature of network and services increases the focus on the changes.  Complex service structures include solutions with low Customer Care Management System. In the several underlying platforms it can be easily deployed for the management policy, topology management, service centric Modelling and integration, and customer service management (Vesalainen, Valkokari, & Hellström, 2017).

The issue of customer interaction is compared with the open market factors such as prices service and quality.  The communication matter for the solution of problem and communication level increase in this way.  Operators must priorities the work to find gap between care and corresponding technical network management. The pressure to cut operation cost is another issue. The interface management is huge software integration project. The complexity and cost of this management interface is different from other. In this model point to point integration is considered for network Management Solutions (Arpege Group, 2012).

Sometimes organizations got stuck with the reactive mode of network and existing network management tools are used to manage the network. At this time the business users face underlining Technology. The demand for organization increases for reliable network maintenance for the system. Instead of having the latest information and system of Gigabyte network hardware most often organizations prefer to have network management without having any type of bandwidth issues, performance issues, and slow responsiveness to the uses. Organizations have developed a network Management Solutions to overcome the complexity and cost issues (Vesalainen, Valkokari, & Hellström, 2017). The single GUI implementation is easy and Rapid process that reduce our investment and provide a strong standard basis. The operational model depends upon data centre Management and Technology that sports internet technology. The basic step is deployment strategy, the proactive network Management Solutions are considered to manage the operations. The configuration management reflects the network topology. Network management parameters include monitoring of configuration, fault, and performance. Fault management considers location change and contact change along with system time up. The interfaces are added or deleted by using interface operating status and interface administrative status. The performance management parameters include packets received on the interface, packets transmitted on the interface, interface error, interface link speed, the average packet size of the interface, and TCP segments received and transmitted (Wallin, Ahlund, & Nordlander, 2012). The Other parameter for distributed and parallel systems is TTL value that is time to live field, IP addresses, transport layer protected.

The vital concepts of network management depend upon users and their service providers. The vital research items identified for the network service management are listed below,

1.      Mapping and interaction between the obstructive Service model and implementation of corresponding service system.

2.      Mapping of service implementation and service-oriented Q OS parameter.

3.      Different service Chain and mapping of service agreements

4.      Interaction between the provider and the customer

 Future perspectives of Network management

  The system used in this analysis demonstrated genius versus network management. The design makes the management controllable by large scale network simulations. One direction for the future work of this management system is not limited to a single computer it can be used for a number of operations at multiple systems.  Domain models are also designed to capture explicit knowledge from experts. It provides validation of interfaces in-network and enables automatic rendering of the network management system. There are different aspects of network management that are hard to capture in explicit models. The correlation approaches are used to develop rural development struggle model. Network administrators are flooded with specified and predict paper procedures. There are three types of layers including service layer application layer and transport layer in the domain model. This model can be used to run and monitor service level agreements with attractive output and graphical approaches (Vesalainen, Valkokari, & Hellström, 2017).

Conclusion of Network management

The present report considered large and Big complex network systems.  Such type of network systems is harder to manage due to heterogeneity and complexity in the design and Systems. One of the common serious problems is conceded in the report. The main issue is fault management and connectivity failure. Network Management Solutions are simple to be implemented.  The present model simple graphical user interface is considered to overcome the issues and this method is easy and Rapid with cost-effective properties. The whole model reduces over investment studying the stock market. The administration and network management must apply the tool effectively and monitor the performance of the model. The remote devices can be used to manage the performance and control of the centre point of the devices. Insert type of models the output utilisation and input unit utilisation are also considered. In the present analysis, one such a management solution was considered by using the HP openview. The results implemented reduced the number of network devices and ultimately reduce the cost off the network management system. The improvement model reduces downtime of the devices. The high performance of the network is available by the results therefore the implementation of the model reduced issues challenges and problems and higher performance of the network is fast as compared to previous. The response time is due to proactive network management and implementation of the model was appreciated by the users because a working system was very smooth.
