IEEE 802.3ad is a networking standard that defines a method for combining multiple network connections into a single logical link. This process, known as link aggregation, enhances bandwidth and provides redundancy, ensuring that if one connection fails, the others can continue to carry traffic. The standard is widely used in Ethernet networks, allowing devices like switches and routers to work together more efficiently. By grouping several physical links, IEEE 802.3ad helps improve overall network performance and reliability, making it a valuable tool for businesses and data centers that require robust connectivity.
