Network FundamentalsIn the existing learning phase, if you test the network and the basic is through the ping command ( in the production environment in order to prevent attacks almost all of the servers are banned ping), but it is often unclear what the command is doing behind the scenes, well, look down on the right1.1Routing/Routers：The router (Router) is a
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
1. What is bonding;The Linux bonding driver binds multiple network interface devices to a single network interface setting for network load balancing and network redundancy. The Linux bonding Driver provides a method for aggregating multiple network interfaces into a single logical bonded interface. the behavior of the bonded interfaces depends upon the mode; gen
the bandwidth of network devices and servers and improve the flexibility and usability of networks by making multiple links virtual into a logical link. This article introduces the bonding technology under Linux, Linux 2.4.x kernel using this technology, the use of bonding technology can be the interface of many cards through the binding virtual into a network card, in the user's view this aggregation of

Check to see if your system supports bonding First, execute the command: $rpm-qf/sbin/ifup It returns a line of text, beginning with "initscripts" or "Sysconfig", which is the package that provides the network initialization script. Next, to determine if your installation supports bonding, execute the command: $grep Ifenslave/sbin/ifup If any matching records are returned, your initscripts or sysconfig s

Configure the NIC Bonding for the RAC Private Network In the installation and deployment process of RAC, it is not just a simple installation.

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)
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
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
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

Bonding Study Bonding IntroductionBonding to bind multiple network cards to the same IP address to provide services externally, can achieve high availability or load balancing. It is not possible to film the same IP address directly for two network cards. Through bonding, a virtual one network card to provide external connection, the physical network card is modi
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
