The loop prevention may be initiated by a root node and a token may be generated by the root node when completing the prevention. Network nodes may reduce ingress data rate during loop prevention.

Abstract: The present disclosure discloses a method for multi-homing path selection of a stream control transmission protocol (SCTP). The method includes the following steps of: starting quality evaluation of paths; calculating a quality evaluation value of each path; comparing the quality evaluation value of each path; and selecting a path with the highest quality evaluation value to transmit a data message.

Abstract: A first site comprises a first ISP, a first server and a first router interposed between the first ISP and the first server. A second site comprises a second ISP, a second server and a second router interposed between the second ISP and the second server. While the second server is operating, both the first and second routers broadcast announcements of an IP address of the second server. The announcements of the IP address broadcast by the first router indicate the first router as a less preferred route to the IP address than the announcements of the IP address by the second router indicating the second router as a route to the IP address. Consequently, packets addressed to the IP address are routed to the second server via the second ISP and the second router. Subsequently, the second site fails, and concurrently, the second router ceases to broadcast announcements of the IP address of the second site and the first router continues to broadcast announcements of the IP address of the second site.
