Outbound Link Load Balance
This example shows how to configure outbound link load balancing. Through the configuration of efficient drainage strategy to achieve dynamic link load balancing, improve the export bandwidth utilization.
As shown in the following figure, this lab environment simulates the deployment of equipment at the second-level ISP exit scene.The second-level ISP rent Tele-com, China Netcom and other operators of the bandwidth to the user to achieve Internet access. The figure use 126.96.36.199 to connect to the Internet by Tele-com and 188.8.131.52 to connect to Netcom.
|Step 3: Configure the outbound load balancr profile|
Select Network > Outbound >Profile, click New.
|Step 4: Configure the outbound load balancr rule|
Select Network > Outbound >Rule, click New.
|Step 5: Verify that outbound load balance is in effect|
After completing the above steps, use the test tool to construct traffic through ethernet0/1 and ethernet0/2, respectively, and then observe the traffic on each link.By changing the size of outgoing traffic,you can find that the traffic on two links can be adjusted equitably. The system routing mechanism is as follows:
- Q: What factors in the network affect the link load balancing routing of the system?
A: The delay, jitter, packet loss rate and bandwidth utilization of each link are the impact factors. System can intelligently oute and dynamically adjust the traffic load of each link by monitoring the delay, jitter, packet loss rate and bandwidth utilization of each link in real-time.
- Q: Which modes do link load balancing support?
A: Two load balancing modes are supported, namely, high performance and high compatibility modes.
High Performance - In this mode, system adjusts link to keep the link balance as fast as possible
High Compatibility - In this mode, When the link load changes, system does not switch the link frequently, but ensures that the service is as far as possible on the previous link. This mode is suitable for services that are sensitive to link switching, such as banking services, only when the previous link is overloaded.
