With network development, Wireless Fidelity (Wi-Fi), a low-cost and highly efficient network deployment and maintenance mode, has been widely recognized by customers. However, Wi-Fi's high requirements on environment and disperse deployment of a large number of ACs and APs on WLAN networks have made the maintenance costly and difficult. Therefore, an easy-to-use and efficient WLAN management system is the key to ensure enterprises' end-to-end (E2E) operations.
Huawei Sight WLAN Manager integrates the management of wired and wireless networks, and enables service deployment in batches, service adjustment, troubleshooting, and routine maintenance.
As the network scales and the number of enterprise network applications continue to grow, so does the number of devices, such as multi-service routers, gateways, and WLAN Access Points (APs), which enable communication and collaboration in decentralized networks like enterprise campus networks and branch office networks. An increasing number of core and access devices from multiple vendors are used in the enterprise, each with its own management system, creating a nightmare for the system and network administrators.
To alleviate the operational burden, Huawei has developed a unified network management system to provide a comprehensive view and management of all network and system resources, to ensure network stability, and improve O&M efficiency: Sight.
Huawei Sight Unified Network Management Platform provides various editions (compact, standard, and professional) for enterprises. In addition to uniform management of devices from various vendors, topology management, fault management, performance management, smart configuration tool, and configuration file management, Sight Unified Network Management Platform allows users to customize management of third-party devices, helping users to establish a network management system catering for their own needs.
With rapid network development and continual integration of network applications and service management, information increases exponentially. It is impossible for administrators to obtain valuable information from the bulk information. Therefore, enterprises are in an urgent need of an information management system that can collect, arrange, analyze, and display data to help improve operating efficiency. The information display mode directly affects users' understanding and provides the basis for decision making. Sight provides a powerful report analysis and design tool (Sight Smart Reporter). Huawei Sight Smart Reporter provides preset report templates to meet requirements in most maintenance scenarios and provides the professional report design tool for users to customize statistics reports.
Fast, stable access speeds improve working efficiency, while low access speeds often affect office work. How can customers determine which applications consume a lot of bandwidth and generate heavy traffic and which employees use these applications? Is it necessary to change the network QoS policy or to expand the network? Network Traffic Analyzer supports NetFlow, NetStream, and sFlow. NTA collects traffic information output by routers and Layer 3 switches, and it provides user-defined reports that network administrators can analyze to learn about traffic and bandwidth usage and find network bottlenecks. NTA also provides information that network administrators can use for network planning and troubleshooting.
The increasing number of services carried by the IP network makes it difficult to ensure user experience. Administrators must detect potential faults in advance and use efficient fault diagnosis methods to quickly troubleshoot and recover services. Huawei Sight SLA Manager integrates with devices' NQA function to diagnose and measure the link performance between network devices 24/7 hours and display QoS in statistics. Administrators can set the QoS threshold. Sight notifies administrators remotely when QoS reaches the threshold. Administrators can also use the quick diagnosis function to monitor link performance in real time and diagnose faults, which improves maintenance efficiency.
With rapid network development, an increasing number of users transmit data through networks. IP networks carry not only data services but also VoIP, VPN, and ERP services to meet diversified user requirements. The new services have a common feature, that is, high requirements on transmission performance such as bandwidth, latency, and jitter. Users want better experience during packet transmission. The QoS technology provides various QoS functions based on the requirements of different applications on the network, such as providing dedicated bandwidth, reducing the packet loss rate, managing and avoiding network congestion, adjusting network traffic, and setting packet priorities. Unified QoS management can manage network-wide QoS services in a centralized way to ensure network QoS.
Huawei Sight QoS Manager monitors network QoS in real time provides multi-dimensional data analysis, and displays QoS information in graphs and dashboards, simplifying network management. Integrating with the smart configuration tool, performance monitoring, Network Traffic Analyzer, and SLA Manager on Sight Unified Network Management Platform, Sight QoS Manager provides all-round functions of QoS configuration, monitoring, and optimization.
The tunnel technology is widely used in networks. Enterprises choose tunnels based on service features. Generally, LDP tunnels carry services that have low requirements on bandwidth and QoS, and MPLS TE tunnels carry services that have high requirements on bandwidth and QoS. To ensure that services run properly, administrators must know the following tunnel information on the current network: number of tunnels, tunnel types, path of each tunnel, tunnels with the protection function, and whether a tunnel switchover occurs.
Huawei Sight MPLS Tunnel Manager automatically discovers the MPLS TE tunnels (RSVP-TE signaling-based dynamic tunnels and CR-Static signaling-based static tunnels) and LDP tunnels that have been deployed on the network, monitors the tunnels in real time, and displays tunnel running status dynamically. In addition, Sight MPLS Tunnel Manager monitors active-standby switchovers and bypasses.
Virtual private networks (VPNs) are complex. They bear various services such as data, voice, and video. Huawei Sight MPLS VPN Manager is introduced to deal with the complexities such as the following in routine maintenance:
How to shield service complexity and let maintenance personnel know the running status of deployed VPN services in real time and perform troubleshooting in a timely manner? How to monitor the bandwidth usage of each service to ensure the priority of emergency command systems and important users?
How to ensure the cross-region video conference quality among provinces, cities, counties, and towns?
Huawei Sight MPLS VPN Manager integrates discrete VPN information on the network into visible manageable objects and displays them in topology. Administrators can easily monitor VPN services and diagnose faults to ensure QoS and reliability of key services.
With the help of virtualization software, one physical server can be virtualized to multiple VMs that share computer resources. To ensure communication between VMs and communication between VMs and switches, the virtual switch vSwitch is introduced. On the one hand, a vSwitch is deployed on a server and managed by the system administrator; on the other hand, a vSwitch is a switch that is managed by the network administrator. The unclear boarder between network management and server management requires cooperation between the system administrator and network administrator.
Sometimes, VMs that occupy fewer resources are migrated to another server to free unnecessary servers and reduce cost. Sometimes VMs are migrated to new servers that are added to satisfy service needs. To meet the VM migration requirement, the destination network where a VM is to be migrated must be prepared in advanced. This brings new challenges to network management.
Huawei Sight DC nCenter monitors network resources (including physical servers, VMs, vSwitches, and TOR switches), displays the topology of virtual resources and physical devices, and dynamically adjusts physical network profiles based on VM changes.
Traditionally, network administrators have to work 24/7 in surveillance centers in order to have a real-time understanding of the running status of devices and services on a network. With the rapid development of information technologies and the wide spread use of wireless applications, remote surveillance and mobile office have become a growing trend. There is an urgent need for a mobile network management system that allows network surveillance and fault diagnosis to be conducted anytime and anywhere.
Huawei Sight mobile is such a solution that can cater to these industry needs with its intelligent terminal-based network management system. With Sight mobile, users can monitor a network's status, diagnose faults, and request for online technical support at anytime from anywhere.
