Media Manager Configuration for Virtual Machines (VM)
The Oracle® Enterprise Session Border Controller (E-SBC) provides you with a means of tuning the media manager for VM deployments.
As the E-SBC can classify traffic for use in DoS policing, bandwidth may be reserved for certain traffic types. Reserved bandwidth is expressed as a percentage of maximum available system bandwidth. The system's maximum bandwidth is determined by the hardware configuration and the number of available signaling cores. The maximum system bandwidth is defined as the speed of ingress traffic sent to the host, measured in packets per second (PPS). It is reported in the show platform limits command, referring to the "Maximum Signaling rate".
The following configuration options are available in the media-manager-config. These options are used to configure reserved bandwidth for application signaling, and ARP, and untrusted traffic.
- max-signaling-packets—Set
the maximum overall bandwidth available for the host path in packets per
second, which includes signaling messages from trusted and untrusted sources.
The maximum value for each platform is used as the default value for that
platform.
- The maximum depends on
the platform, as follows:
- Acme Packet 1100 platform: the maximum is 10,000
- Acme Packet 3900 platform: the maximum is 40,000
- COTs and VM platforms: the maximum is system dependent
- The maximum depends on
the platform, as follows:
- min-untrusted-signaling—The minimum percentage of maximum system bandwidth available for untrusted traffic. The rest of the bandwidth is available for trusted resources, but can also be used for untrusted sources per max-untrusted-signaling. Default: 30. Range: 1-100.
- max-untrusted-signaling—The percentage of the maximum signaling packets you want to make available for messages coming from untrusted sources. This is a floating highwater mark and is only available when not in use by trusted sources. Default: 100. Range:1-100.
- tolerance-window—The size of the window, in seconds, used to measure host access limits for measuring the invalid message rate and maximum message rate for the realm configuration. Default: 30. Range: 0-4294967295.
- max-arp-rate—The maximum percentage or max-signaling-packets available for ARP traffic. Default: 30. Range: 1-100.
The user can also set controls on untrusted traffic from either realm or static ACL configuration using the untrusted-signal-threshold parameter.
