Successful companies know that network management is crucial for the proper support and maintenance of network infrastructure. When it comes to managing a large-scale or highly complex network, you’ll need a powerful network management system that will meet your challenging business needs. There are several programs suggested different types of solutions. PRTG and SolarWinds are an excellent solution, since they have many features that help the network engineer, administrator or technician to easily control, manage and monitor the devices comprehensively. Moreover, PRTG and SolarWinds can integrate with monitoring and management protocols such as SNMP and NetFlow to provide an excellent integrated unified management solution. That being said, PRTG and SolarWinds will facilitate the management of network devices throughout performing configuration, Security, Fault, Performance and Accounting management which will increase productivity, Quality, Revenue and lower the cost. arabic 9 English 66

Multi Protocol Label Switching (MPLS) is a core networking technology that operates essentially in between Layers 2 and 3 of the OSI model; for this reason, MPLS has been referred to as operating at Layer 2.5. MPLS can overlay existing technologies such as Asynchronous Transfer Mode (ATM) or Frame Relay, or it can operate in an entirely IP native environment; this can allow users to take advantage of existing Customer Premises Equipment (CPE) while making a move towards converging all network traffic, such as data, video and voice, at a pace that users can accommodate and afford. MPLS provides. its users a number of advantageous features such as traffic engineering, network convergence, failure protection, and the ability to guarantee Quality of Service (QoS) over IP. arabic 2 English 27
