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 |
20150222543 | VIRTUAL MAC ADDRESS, MASK-BASED, PACKET FORWARDING - A destination Media Access Control (MAC) address of a packet is determined. In response to determining that the destination MAC address is a virtual MAC address and belongs to an access device, mask-based, virtual MAC address, the packet is encapsulated with a Very Large Layer 2 (VLL2) network protocol header, and sent to an access device associated with the access device, mask-based virtual MAC address. | 08-06-2015 |
20150319139 | 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. | 11-05-2015 |
20150341183 | FORWARDING MULTICAST DATA PACKETS - According to an example, a method for forwarding multicast data packets includes receiving a first multicast data packet having a first multicast address, in which the first multicast address belongs to a first multicast group having a multicast source inside of a data center and sending the first multicast data packet through a designated router (DR) router port and a gateway router port, in which the DR router port and the gateway router port correspond to a virtual local area network identifier (VLAN ID) identified in the first multicast data packet. | 11-26-2015 |
20160080244 | HOST MOBILITY MESSAGING - The presence of a host is detected at a first data center. A message is generated at the first data center to indicate the presence of the host. The message has a limited lifetime. The message is transmitted to a second data center. | 03-17-2016 |
