The company leases multiple ISP links, how to ensure effective access to background applications?

I have configured F5 LC products for others, and I personally feel that it is good, and it can realize intelligent dynamic load balancing of traffic for multiple links. When a link fails, it can automatically switch to a healthy link without affecting existing network applications (including incoming and outgoing traffic). This ** has a detailed introduction to the F5 product, you can take a look.

I remember that there is a product called LC link control, which specializes in load balancing applications for this kind of link, and it seems to be able to automatically judge the health of the link and keep the network access smooth. This ** has a very detailed introduction to it, if you want to understand, you might as well take a look.

The upstairs is good, I will add one more point: one of the key functions of F5's Link Control product is to support inbound load balancing, which can provide static and dynamic link load balancing functions for internal servers (configured with private or public addresses), so that after the external network access to the school server is optimized, the user's information is sent back from the fastest route.

is a dedicated interface.

Sometimes it's fiber. (more now).

Generally, it is optical fiber ethernet.

There are no requirements, serial links are almost never seen.

Use an optical interface Generally, the campus network ISP is an optical interface.

Exact routes have the best priority, followed by default.

Your situation needs to be solved by a dedicated link load balancing device, such as F5. Firewalls alone cannot accurately provision four links.

Relying on the metric can only statically solve the routing problem, and cannot dynamically adjust the link quality, jitter, delay, etc.

If the priority of the default route is higher, it will still be matched in order.

The weights are port-specific and do not stack.

According to your configuration, there are two routes during the day.

The configuration on the static route can be used to divide the route in detail by the weight, and you can also use it flexibly in combination with the routing protocol, which will be more effective.

You're challenging, and I've tried there's no way to make an intelligent allocation based on the current network load. You can only choose professional load balancing equipment, foreign F5, domestic ones like Shanghai Yunsu Network Technology, but our company has one in the computer room.

Not at all.

The server is placed in the IDC data center. The IDC has access to the bandwidth itself. Whether it's renting or hosting a server.

It's up to the service provider to help you access the server bandwidth. Configure the IP and make it available for you to use. Bandwidth and traffic are already provided by default.

Moreover, the domestic computer rooms are all unlimited. You can use it as much as the bandwidth allows.

Generally speaking, you don't need to buy data separately, even if it's not completely free, but the service provider will also provide you with a free quota, and you will only need to pay if you exceed the quota. Hope it helps. Times Connect has the answer for you.

You can use cloud servers, you don't need to buy additional traffic, only bandwidth limits, no traffic limits.

You can try it out and find us.

That's a lot. For example, Wanwang, Xinnet, Huaxia Famous Network, Western Digital, etc.

There are all provinces, and it is recommended to choose a service provider that is closer to your area.

Jinan Enterprise Union will answer for you.
