We all know that any site on the network, including routers, switches, servers, and general sites, must communicate with the network through the NIC. As the number of sites on the network increases, the use of network cards naturally increases. Nic faults also increase significantly. Many users do not pay enough attention to the network card. For example, the cheapest network card is tens of RMB, while the

NIC teaming is one of the many network features introduced in Windows Server-Hyper-V 3.0. The NIC teaming was originally designed for Windows Server 2012 and can now be used to configure a bound adapter for Hyper-V virtual machines. This article mainly describes how to configure NIC teaming on Windows Server 2012 or later. Of course, Windows administrators can u

Server load balancer is another feature of network card bonding. it can work with multiple network cards at the same time to improve the throughput of system network processing. 1.

Linux supports NICs through the kernel. In the early days, many people directly add Nic support during compilation. However, with the increase of NIC types, few have used this thankless method. Currently, most people use the NIC module to drive the NIC. In order to join the network card, you must first know the network

Linux can always implement a complex function in the simplest way, especially in terms of NetworkEven if this function is considered to be available only on high-end devices, Linux can easily implement it. The previous articles have already said many times, such as VLAN functions, for example, advanced routing and firewall functions. This article focuses on Linux bonding, which is the functional module of port aggregation. It is undeniable that at the network device level, Linux has developed tw
