Linux Multi-NIC Binding overviewThis article os:6.4 test here is four NIC bound 1 block bondWe introduce the Linux dual-NIC binding implementation is the use of two network card virtual become a network card, the aggregation of the device appears to be a separate Ethernet interface device, the popular point is that two network cards with the same IP address and parallel link aggregation into a logical link work. In fact, this technology has long existed in sun and Cisco, known as Trunking and Et

Tag: Bonding About Nic Bonding Nic binding virtualizes multiple physical NICs into a virtual Nic through software. After configuration, the IP addresses and MAC addresses of all physical NICs become the same. Multiple NICs can work at the same time to increase network speed and achieve load balancing and redundancy of NICs. Bonding mode 1 round-robin (mode = 0)

Configure the NIC Bonding for the RAC Private Network In the installation and deployment process of RAC, it is not just a simple installation. The possible single point of failure (spof) should be considered during the installation process. The most important part is the private network. A private network is a channel for communication between RAC nodes, including network heartbeat information between nodes and data blocks transmitted through Cache fu

In the installation and deployment process of RAC, it is not just a simple installation. The possible single point of failure (spof) should be considered during the installation process. The most important part is the private network. A private network is a channel for communication between RAC nodes, including network heartbeat information between nodes and data blocks transmitted through cache fusion. Many private networks only connect to a vswitch with a single Nic. What's more, they directly

First, what is the network card binding and simple principle Network card binding is also known as "network card bundle", is to use more than a physical network card virtual network card to provide load balancing or redundancy, increase the role of bandwidth. When a NIC is broken, it does not affect the business. The converged device looks like a separate Ethernet interface device, where the network cards have the same IP address and the parallel link is aggregated into a logical link. This tec

By bundling multiple Linux network ports into one, you can improve the performance of your network, such as backing up a server that needs to back up several T data at one night,The use of a single gigabit network port will be a serious bottleneck. Other applications, such as FTP servers and high-load download sites, have similar problems.Therefore, using Linux teaming or bond to bind multiple network cards as a logical network port, configuring a single IP address can significantly increase the

We will introduce how to bind two NICs in Linux to a virtual network card. The aggregated device looks like a separate Ethernet interface device, in general, two NICs have the same IP address, and parallel links are aggregated into a logical link. In fact, this technology already exists in Sun and Cisco, known as Trunking and Etherchannel technology. It is also used in Linux 2.4.x kernel, known as bonding. The earliest application of

Settings for Linux under bondingBonding IntroductionThe Linux bonding driver provides a bundle of multiple network interface devices into a single network interface setting for Network Load Balancing and network redundancy.1. Network Load BalancingFor bonding Network Load Balancing is we commonly used in the file server, such as the three network card, as a piece to use, to solve an IP address, traffic is t

The so-called bonding means to bind multiple NICs to the same IP address to provide external services, which can achieve high availability or load balancing. Of course, it is impossible to directly set the same IP address for the two NICs. Through bonding, a virtual network card provides external connections, and the physical network card is changed to the same MAC address. Kernels2.4.12 and later versions
