20130064247 | METHOD AND DEVICE FOR PROCESSING SOURCE ROLE INFORMATION - A method and device for processing source role information in which a source role tag is inserted into a packet as an inner VLAN tag of the packet and used to perform role based access control processing for the packet. | 03-14-2013 |
20150023352 | IMPLEMENT EQUAL COST MULTIPLE PATH OF TRILL NETWORK - According to an example, a method for implementing ECMP in a TRILL network includes: forming a backup group with multiple primary Routing Bridges (RBs) interconnected in the TRILL network; configuring an IP address and a MAC address both associated with each virtual Gateway for each primary RB; configuring a same virtual RB identifier for each primary RB; advertising, by each primary RB, adjacency information about a neighbor RB identifier within the TRILL network; wherein the adjacency information about the neighbor RB identifier includes adjacency information about the virtual RB identifier; enabling a secondary RB accessing a host in the TRILL network to compute and obtain the ECMP information associated with the virtual RB identifier in the TRILL network, in which next hops in the ECMP information associating with the virtual RB identifier are the primary RBs in the backup group are in a one-to-one correspondence. | 01-22-2015 |
20150085640 | Forwarding Multicast Data Packets - A gateway routing bridge of a data center, obtains nicknames of designated routers (DR) of a multicast group in each virtual local area network (VLAN); calculates distribution trees rooted at each DR; receiving a multicast data packet from a multicast source of the multicast group which inside the data center; and sends the multicast data packet on the distribution tree rooted at the DR which corresponds to a multicast address and a VLAN identifier (VLAN ID) of the multicast data packet. | 03-26-2015 |
20150085862 | Forwarding Multicast Data Packets - A non-gateway routing bridge of a data center, receives multicast data packets from a multicast source inside the data center and sends the multicast data packets through a designed router (DR) router port and a gateway router port. The DR router port and the gateway router port correspond to a virtual local area network identifier (VLAN ID) and multicast address in the multicast data packet. | 03-26-2015 |
