How can I limit the total speed of a port or domain name?

[tssungeng]

You know,the  ngx_http_limit_zone_module can limit the speed of an IP .

I want to limit the total speed of a port or a domain name.

For example:
There was a Server(the all speed is limited by the IDC 10M/s).
There was a Nginx on the Server.
There was two port for this Nginx---> 8080 and 8090,now I want to limit the
total speed of 8090 to 5M/s,No matter how match ip,No matter how match conn
per IP.
