. Generally, Server Load balancer is divided based on different layers of the network (layer-7 network. The second layer of Server Load balancer refers to the use of multiple physical links as a single aggregation Logical Link. This is the trunking technology, which is not an independent device, it is a common technology used by switches and other network devices. Modern Server Load balancer technology usually operates on Layer 4 or Layer 7 of the net

5 minute DBA-database server hardware selection describes some ways to help the database select hardware, which is actually biased towards MySQL... Simply put, it is of little significance to have a CPU larger than 8. You do not need to buy 4*4 Core or 4*6 Core because MySQL cannot be used at present. The larger the memory, the better the memory, the much cheaper It is now. If I/O bound is faulty, it is usually the most cost-effective method to directly add the memory to 32 GB or 64 GB in addit

In this article, the implementation of dual-Nic binding in Linux is to use two NICs to virtualize a single NIC. the aggregated device looks like a separate Ethernet interface device. Generally speaking, two NICs are used. In this article, the dual-Nic binding implementation in Linux is to use two NICs to virtualize a single NIC. 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 l

In Linux, dual-nic binding is achieved by virtualizing two NICs into one Nic. In other words, two NICs have the same IP address, and parallel links are aggregated into one 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. Under normal circumstances, the network adapter only receives the target hardware Address (MAC Address) as

network. FSM726 is a network-managed switch that provides two management methods: WEB browser management and command line interface management. It manages SNMP, VLAN, QoS, Port Trunking, broadcast storm control, and Port Mirroring through these two management methods, which greatly improves the utilization of network resources. Because the vswitch supports remote control, it also provides protocol authentication. Users can connect to FSM726 only afte

bridging (that is, isolating conflicts) and forwarding data packets, a switch also has other advanced features, such as vlan (Virtual LAN), port trunking (connection aggregation ), spanning tree (spanning tree) and other features. High-end switches also provide routing functions. The specific routing functions will be described later. A vswitch is a dedicated network device based on hardware, so it has a higher data forwarding capability than a softw

Deploy DSM and remember to set up ocdb. It is not recommended to install the relay at installation time.

lower bound of the array. In our example, It is 3. This number is different from the size of the byte. These bytes are lower bounds of the dimension, and their size has been specified in advance. If the value is 0, no lower bound is specified. The 3rd arrays and 6 appear together, but in the Il file, it is reflected as 3. This is because the number is signed, so they need to be decompressed first. In this way, the system checks 1st bits. Because it is not set, these bits are moved by only one b

Load Balancing at the network level To address the different bottlenecks of heavy load on the network, we can start from different network levels and adopt the corresponding load balancing technology to solve the existing problems. As bandwidth increases and data traffic increases, data interfaces in the co

Bind an IP address to a Linux dual-nic. The actual task is to use two NICs as one. Using the same IP address is a better and faster service. Here we use RHLE3 to experiment on this job. Bind an IP address to a Linux dual-nic. Here we will introduce the specific practices. The following section describes some problems.

I. Introduction In Linux, dual Nic binding is implemented by virtualizing two NICs into one Nic. The device combined seems to be 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

However, if a port is configured as a TRUNK, the port will lose its original vlan id, it does not belong to any VLAN, but serves to transmit data for all VLANs.

second layer means that a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the user's waiting time for response, this mainly targets Web servers, FTP servers, key enterprise application servers, and other network applications.
