When MCU cascading is used (linking multiple MCUs together to scale a conference), Cisco recommends the Active Speaker layout. Continuous Presence and Enhanced Continuous Presence layouts require each cascade link to carry multiple decoded video streams simultaneously, which multiplies bandwidth and processing demands across cascade links. Active Speaker only transmits the single loudest speaker's video across the cascade connection, drastically reducing bandwidth consumption and decoding complexity at each MCU node.
