Ethernet Automatic Protection Switching (EAPS) is used to create a fault tolerant topology by configuring a primary and secondary path for each VLAN.
It was invented by Extreme Networks. The idea is to provide highly available Ethernet switched rings (commonly used in Metro Ethernet). Other implementations include Ethernet Protection Switching Ring (EPSR) by Allied Telesis, "Rapid Ring Protection Protocol" by Huawei/H3C, "ZTE Ethernet Smart Ring" (ZESR) by ZTE.

Famous quotes containing the words automatic and/or protection:
“What we learn for the sake of knowing, we hold; what we learn for the sake of accomplishing some ulterior end, we forget as soon as that end has been gained. This, too, is automatic action in the constitution of the mind itself, and it is fortunate and merciful that it is so, for otherwise our minds would be soon only rubbish-rooms.”
—Anna C. Brackett (1836–1911)
“Ah! how much a mother learns from her child! The constant protection of a helpless being forces us to so strict an alliance with virtue, that a woman never shows to full advantage except as a mother. Then alone can her character expand in the fulfillment of all life’s duties and the enjoyment of all its pleasures.”
—Honoré De Balzac (1799–1850)
