Managing Cross-Site Connection Bandwidths

Scenarios

Add enterprise routers or global DC gateways in different regions to the same policy to set up cross-site connections. Purchase a global connection bandwidth and assign bandwidths for cross-site connections, so that network instances at different sites can communicate with each other over these connections.

You can perform the following operations to manage your cross-site connection bandwidths:

• Assigning a Cross-Site Connection Bandwidth
• Viewing Monitoring Metrics of Cross-Site Connection Bandwidths
• Changing Cross-Site Connection Bandwidth
• Deleting a Cross-Site Connection Bandwidth

Constraints

• A cross-site connection bandwidth cannot be modified or deleted when it is being created, updated, deleted, frozen, unfrozen, or is recovering.
• The total of cross-site connection bandwidths cannot exceed the global connection bandwidth.
• After Deleting a Cross-Site Connection Bandwidth, you will still be billed if the global connection bandwidth is not deleted.

Assigning a Cross-Site Connection Bandwidth

1. Go to the central network list page.
2. Locate the central network and click its name.
3. Click the Cross-Site Connection Bandwidths tab.
4. Locate the cross-site connection and click Assign in the Global Connection Bandwidth column.
5. On the Assign Cross-Site Connection Bandwidth page, select the global connection bandwidth.

   You can also click Buy Now to purchase one if there are no available global connection bandwidths.

6. Enter the bandwidth.
7. Click OK.

Viewing Monitoring Metrics of Cross-Site Connection Bandwidths

You can view the status of each cross-site connection bandwidth assigned for communication between network resources.

1. Go to the central network list page.
2. Locate the central network and click its name.
3. Switch to the Cross-Site Connection Bandwidths tab and click the icon in the Monitoring column to view the monitoring data.

• By setting up a central network, you can enable communications between enterprise routers, as well as between enterprise routers and your on-premises data center, in the same region or across regions. When a central network is used, attachments on the enterprise routers used in the central network policy will be monitored.
• If a global DC gateway is attached to an enterprise router, only metrics of the enterprise router can be viewed.

Changing Cross-Site Connection Bandwidth

1. Go to the central network list page.
2. Locate the central network and click its name.
3. Click the Cross-Site Connection Bandwidths tab.
4. Locate the cross-site connection and click Change Bandwidth in the Operation column.
5. In the displayed dialog box, change the global connection bandwidth of the cross-site connection.

   You can also change the bandwidth size of the cross-site connection.

   

   Select a proper bandwidth size. Excessive bandwidth wastes resources, while insufficient bandwidth limits cross-site data transfer speeds. This can cause higher delays, frozen frames, lost packets, and connection timeouts if the traffic exceeds the bandwidth capacity.

   After the change is done, delete the original bandwidth that is no longer needed to avoid unnecessary billing.

6. Click OK.

Deleting a Cross-Site Connection Bandwidth

1. Go to the central network list page.
2. Locate the central network and click its name.
3. Click the Cross-Site Connection Bandwidths tab.
4. Locate the cross-site connection and click Delete Bandwidth in the Operation column.
5. In the displayed dialog box, click OK.
