Abstract: Embodiments of the present invention provide a method and an apparatus for implementing FCC. The method mainly includes: receiving, by a fast channel change FCC server, a plurality of FCC requests concurrently sent by the same user, and obtaining, rates of a plurality of channels corresponding to the plurality of FCC requests; and when the FCC server determines that the rates of the plurality of channels do not belong to the same rate range, respectively performing channel change processing for the plurality of FCC requests. The embodiments of the present invention may be applied to a scenario in which FCC is concurrently performed corresponding to a large picture and a channel corresponding to a small picture of the same user, and ensure that FCC of the channel corresponding to the large picture and FCC of the channel corresponding to the small picture do not interfere with each other.
Abstract translation: 本发明的实施例提供了一种用于实现FCC的方法和装置。 该方法主要包括：通过快速频道切换FCC服务器接收同一用户同时发送的多个FCC请求，并获取与多个FCC请求对应的多个频道的速率; 并且当FCC服务器确定多个信道的速率不属于相同的速率范围时，分别对多个FCC请求进行信道改变处理。 本发明的实施例可以应用于FCC同时执行对应于相同用户的小图片的大图片和频道的情况，并且确保对应于大图片和FCC的频道的FCC 对应于小图片的通道不会互相干扰。

Abstract: This application describes a multicast packet sending method, apparatus, and system. The method includes a first multicast root node and a second multicast root node belonging to a same VRRP group. The first multicast root node receives a first multicast packet from a specified multicast source, and the second multicast root node receives a second multicast packet from the same specified multicast source, where the first multicast packet and the second multicast packet include same multicast data. The first multicast root node sends the first multicast packet to a first node based on the first multicast root node being a master root node. The second multicast root node discards the second multicast packet based on the second multicast root node being a backup root node. The method reduces waste of a network bandwidth resource.

Abstract: A BIERv6 packet forwarding method, device, and system. The method includes: receiving, by a first network device, a BIERv6 packet, where the first network device is a BFR or a BFER; determining, by the first network device, whether a value of a hop limit field in the BIERv6 packet is less than or equal to a preset threshold of the first network device, where the preset threshold is a value greater than or equal to 2, and is determined based on a quantity of one or more consecutive second network devices connected to the first network device, and the second network device is a device that does not support BIER forwarding; and when the value of the hop limit field in the BIERv6 packet is less than or equal to the preset threshold, avoiding, by the first network device, forwarding the BIERv6 packet.
