Abstract

Techniques and solutions for automatically filtering network broadcast traffic are described. For example, network broadcast traffic can be automatically filtered by turning broadcast filtering on and off (e.g., as a continuous strobe pattern that alternates enabling and disabling of broadcast filtering). For example, a computing device (e.g., via a network interface or management controller of the computing device) can automatically enable network broadcast traffic filtering during a first time period (e.g., a four second time period) and disable network broadcast traffic filtering during a second time period (e.g., a one second time period). A computing device can also automatically enable and disable network broadcast traffic filtering according to an on-off pattern (e.g., based on various criteria, such as network queue size, broadcast traffic volume, etc.).

Claims16

Dependent claims

A method, implemented by a management controller of a computing device, for performing automatic network broadcast traffic filtering, the method comprising:

during a first time period:
enabling, by the management controller, network broadcast traffic filtering that blocks all network broadcast packets received by the management controller during the first time period,
wherein the management controller is a component of a server computing device, wherein the management controller connects to a management network, separate from a general data network, that communicates management network traffic between the server computing device and other server computing devices;
and
during a second time period immediately following the first time period:
disabling, by the management controller, the network broadcast traffic filtering, wherein network broadcast packets received during the second time period when network broadcast traffic filtering is disabled are processed by the management controller;
wherein the first time period and the second time period are repeated by the management controller as a continuous strobe pattern that alternates enabling and disabling of the network broadcast traffic filtering;
and
wherein the network broadcast traffic filtering does not block directed packets.
