Release Information

Statement introduced in JUNOS Release 9.2.

Description

Configure the maximum number of concurrent calls on the virtual BGF. If you configure multiple virtual BGFs for one service PIC or DPC, you can use this statement to achieve a fair distribution of resources between the virtual BGFs. For example, the Multiservices 500 PIC is capable of 10,000 concurrent calls, and you can divide this number between its associated virtual BGFs.

You can overbook concurrent calls to avoid resource idleness. The configured total of all virtual BGF maximum concurrent calls can be greater than the PIC or DPC limit. For example, bgf-1 and bgf-2 are connected to single PIC. If you configure 6000 maximum concurrent calls on bgf-1 and 8000 on bgf-2, bgf-1 can open up to 6000 concurrent calls, and bgf-2 can open up to 8000 concurrent calls. However, when the total number of calls reaches 10,000, neither of the virtual BGFs will be able to open a new context.

If the resources on the PIC are exhausted and no more calls are allowed, the virtual BGF sends an H.248 error message to the gateway controller in response to new call requests.

Note: You must take the virtual BGF out of service before changing max-concurrent-calls and restart the pgcpd process after returning the virtual BGF to service.
