Rate Limits

About Rate Limits

The rate-limits API allows setting per-second and per-minute incoming SIP packets rate limits for devices and whole accounts (realms) that can be used at SBC level. The system level packet rate limits can also be set to protect the whole cluster.

Modify Rate Limits Using API

Using Crossbar to modify rate limits is very simple. There are only three actions:

  • GET - Gets the current rate limits on the document (account or device)
  • POST - Updates the rate limits on the document (account or device)
  • DELETE - Removes the rate limits object from the document (account or device)

JSON object has self-describing structure. The name of the root key is rate_limits.

The application-level system-wide configuration resides in system_config/frontier document and its syntax is equal to the account-level documents.

Account-Level Document

Account-level document contains two sections:

  • The account section sets rate limits for the entire account
  • The device section sets rate limits for devices inside the account (if not overwritten by device-level rate limits)
  • Both sections contain registrations, invites and total_packets” keys with integer values of possible number of packets within per_minute and per_second sections

Device-Level Document

Device-level document contains is one level “higher” and contains only the “device” part which contains registrations, invites and total_packets keys with integer values of possible number of packets within per_minute and per_second sections.

Device-Level Example

{
    "data": {
        "per_minute": {
            "registrations": 60,
            "invites": 60,
            "total_packets": 180
        },
        "per_second": {
            "registrations": 2,
            "invites": 4,
            "total_packets": 7
        }
    }
}
