Radware Server Load balancer project configuration practice analysis II network architecture and configuration process

Next, this section describes the network architecture and configuration process of the RADWARE project. Radware works in active/standby mode. The corresponding networking methods are divided into single-arm networking, dual-arm networking, and triangular transmission.

I. Single-arm networkingThe following networking is called single-arm networking, which is a widely used networking method. This networking mode enables complete master-slave switchover. Generally, the gateway of the server must point to the floating gateway of the Server Load balancer device.

In this network mode, if two levels of switches are connected, the Spanning Tree STP protocol must be enabled for both the core LAN switches and LAN switches to eliminate loops. If the Intranet and Internet are not in the same CIDR block when using a single arm, you can use the 802.1Q Vlan Trunk for configuration. Generally, the server's gateway must point to the Intranet floating gateway of the Server Load balancer device.

We call the IP address virtualized by AD as the IP address of the Server Gateway as a floating IP address, which is the same as the floating IP address of the switch. The virtual IP address that provides external services is called the VIP address.

2. Dual-arm networking

The following networking is called the dual-arm networking, which currently uses many networking methods. Logically, it is a routing method. This networking mode enables complete master-slave switchover. A single-arm physical connection is used. Two physical links are used to connect the Intranet server and the Internet firewall or router. |

In this network mode, if two levels of switches are connected, the Spanning Tree STP protocol must be enabled for both the core LAN switches and LAN switches to eliminate loops.

Generally, the server's gateway must point to the Intranet floating gateway of the Server Load balancer device.
  Iii. Triangular TransmissionFor streaming media applications, a triangular transmission network is used, and the local triangular transmission is also called an out-of-path response. It is a solution to improve overall network performance. Currently, some MTV projects use this networking method. We will not provide a detailed description here.
  The following describes the basic configuration process of Server Load balancer.Only list key configuration content. Other content is different from the data scenario. Some need to be configured, and some do not need to be configured. For example, Client NAT does not need to be configured in common scenarios. The basic configuration includes the following aspects: 1. network topology and address planning 2. initialize configuration 3. configuration of global table items 4. configure IP5. configure routes and gateways 6. configure the global parameters of the dual-host and VRRP7. configure the business to maintain the l Farml Serverl L4 javasyl Cookie Session. synchronize configurations to the slave
  We first determine the overall design scheme of the network topology, and then plan the address and application.1. first look at the network topology.

Determine that two RADWARE server load balancers are active and standby in the business system, and there are eight application servers in the four FARM groups below to determine the ports opened on each server and the protocols used on the ports, create a business application load relationship table.

Now, let's talk about this in this section. We will continue with this section.
