Abstract

En otra modalidad de la presente invención, un método incluye una variedad de operaciones. Una operación es realizada para recibir una unidad de transmisión de datos en un puerto límite de un puente de la primera región. La unidad de transmisión de datos es transmitida desde un puente de la segunda región para la recepción por el puente de la primera región. Una operación es realizada para llevar a cabo el cómputo del estado Designado_Superior de la Máquina de Información del Puerto (PIM, por sus siglas en inglés) para una instancia del Arbol de Expansión Interno y Común (CIST, por sus siglas en inglés), en respuesta a la recepción de la unidad de transmisión de datos. Una operación es realizada para inicializar el cómputo del estado de la Selección del Rol del Puerto (PRS, por sus siglas en inglés) para cada una de la variedad de Instancias del Arbol de Expansión Múltiples (MSTI, por sus siglas en inglés) asociadas con el CIST, en respuesta a la inicialización de la operación del cómputo del estado Designado_Superior de la PIM que es llevada a cabo.
