Abstract: A compound composition for improving bone health and preparation and application thereof are provided. The compound composition is prepared by combining a traditional Chinese medicine extract with chicken cartilage collagen, magnesium, vitamin K2 and vitamin D3. The compound composition overcomes the food safety risk of the existing osteoporosis preventive drugs by adding the traditional Chinese medicine extract for improving osteoporosis and promoting bone health. And the compound composition disclosed can be used as a dietary supplement or health food raw material for preventing or treating osteoporosis. Therefore, the compound composition disclosed is suitable for promotion and application.

Abstract: An RB device creates a primary multicast tree and a corresponding backup multicast tree, and determines whether the primary multicast tree for forwarding traffic fails or not, according to a received first LSP packet; when the primary multicast tree fails, the RB device forwards the traffic using the backup multicast tree.

Abstract: A first routing bridge (RB) according to an example determines whether there is a nickname conflict between nicknames of the first RB and a second RB. If there is a nickname conflict, the first RB determines whether it is a lower priority RB and may modify its nickname if it is lower priority and based on a broadcast of link state packet from the second RB.

Abstract: According to an example, a multicast forwarding entry in a TRILL network may be processed through obtaining a corresponding relationship between a root RB and a VLAN. One VLAN may correspond to one root RB. The multicast forwarding entry of the VLAN corresponding to the root RB of a multicast distribution tree may be computed according to the corresponding relationship between the root RB and the VLAN.

Abstract: A method for load balancing based on Transparent Interconnection of Lots of Links (TRILL) is provided. Said method comprises: acquiring, by a routing bridge (RB), all current medium access control (MAC) addresses within each virtual local area network (VLAN) on a link where the RB is located. And if said RB is selected as a designated routing bridge (DRB), said RB distributes all the current MAC addresses acquired within each VLAN between said RB and other RBs on the same link according to a preset distribution rule, and notifies said other RBs to be responsible for forwarding of messages having a specified MAC address and VLAN, wherein said MAC addresses are the MAC addresses of the host devices on the link where said RB is located.
