Network topology refers to the connection mode and structure between Hong Kong server devices, common star topology, bus topology, ring topology, tree topology, network topology and so on. In the actual network design of the equipment room, the topology combination is selected according to the specific service requirements and network scale. The combination of basic topologies or the derivation of more complex topological designs can achieve better scalability, redundancy and reliability. A typical network room topology includes core switches, aggregation switches, access layer switches, server groups, security devices, and storage devices.
In a star topology, all devices are connected to a central node, such as a core switch. This kind of structure is simple but easy to manage and expand, and the failure of the central node may affect the entire network. The bus topology is that all the devices are connected by a shared bus, the structure cost is relatively low, but the scalability and reliability are poor.
Ring topology uses ring connections, where each device is connected to two adjacent devices. This method has high redundancy and reliability. But the ring structure link failure will affect the whole network. The tree topology combines the advantages of star topology and bus topology, and the hierarchical connection has better scalability and manageability. Mesh topology is directly connected, with the highest redundancy, reliability, but high cost.
Bandwidth management is to properly apply and allocate bandwidth resources to meet bandwidth requirements of different services, ensure the normal running of critical services, and improve network performance and user experience.
The bandwidth required by Intranet users is generally greater than the egress bandwidth of service providers. Therefore, the egress bandwidth bottleneck is easy to occur. This is where bandwidth management comes in. The system schedules and allocates bandwidth resources based on service requirements to ensure adequate bandwidth for critical services and improve bandwidth utilization at the network egress. Priority is given to key services, especially high-traffic services such as P2P, which occupy a large amount of bandwidth. Effectively control the bandwidth usage at the network egress to avoid bandwidth bottlenecks, improve network transmission speed and stability, and improve Intranet network performance and user experience.
Bandwidth management uses multiple filtering conditions, such as SSID, source/destination security zone, service, application, DSCP priority, and time range, to implement fine-grained control and management of traffic passing the device. Bandwidth policy rules match traffic of different services. You can filter, act, and take effect traffic of different services based on bandwidth policy rules. You can create a bandwidth channel and configure traffic limiting, detecting, and referencing bandwidth resources to effectively manage bandwidth resources.
