Patent number: 11102115Abstract: According to an example of a method for forwarding a packet, a ESGW device decapsulates a received downstream data packet to obtain a downstream IP data packet when a destination MAC address of the downstream data packet is an MAC address of the ESGW device; determines a matching ARP entry of an IP address of a target user terminal based on the destination IP address of the downstream IP data packet to obtain a session ID of the target user terminal; determines a length field of a PPPoE header by a microcode, and obtains a pre-stored fixed-value field of the PPPoE header from a data storage area; encapsulates the downstream IP data packet into a downstream PPPoE data packet based on the session ID, the length field, and the fixed-value field, and forwards the downstream PPPoE data packet through an egress port of the matching ARP entry.Type: GrantFiled: May 31, 2018Date of Patent: August 24, 2021Assignee: New H3C Technologies Co., Ltd.Inventors: Yang Zhang, Ling Kuang

Patent number: 10313275Abstract: I/O board of a VXLAN switch removes VXLAN encapsulation from a packet, determines to perform layer 3 forwarding for the packet and sends the packet to a fabric board of the VXLAN switch. The fabric board determines to perform layer 3 forwarding for the packet, searches out a layer 3 entry matching a destination IP address of the packet from a local layer 3 table, modifies a source MAC address of the packet into a gateway MAC address of the VXLAN switch, modifies a destination MAC address of the packet into a destination MAC address in the layer 3 entry, and when an egress port in the layer 3 entry is a VLAN port, sends the packet to an I/O board associated with the egress port. The I/O board associated with the egress port forwards the packet to a VLAN via the egress port in the layer 3 entry.Type: GrantFiled: May 4, 2016Date of Patent: June 4, 2019Assignee: New H3C Technologies Co., Ltd.Inventors: Yang Zhang, Ling Kuang, Minghui Wang, Hongyuan Zhang, Hai Hu, Guangliang Wen

Patent number: 10313274Abstract: I/O board of VXLAN switch removes first VXLAN encapsulation from a packet, determines to perform layer 3 forwarding for the packet and sends the packet to a fabric board of the VXLAN switch. The fabric board searches out a layer 3 entry matching a destination IP address of the packet from a local layer 3 table, modifies a source MAC address of the packet into a gateway MAC address of the VXLAN switch, modifies a destination MAC address of the packet into a destination MAC address in the layer 3 entry, and when an egress port in the layer 3 entry is a VXLAN tunnel port, sends the modified packet to an I/O board associated with the egress port in the layer 3 entry. The I/O board associated with the egress port receives the packet, adds second VXLAN encapsulation to the packet and forwards the packet to a VXLAN.Type: GrantFiled: May 4, 2016Date of Patent: June 4, 2019Assignee: New H3C Technologies Co., Ltd.Inventors: Yang Zhang, Ling Kuang, Minghui Wang, Hongyuan Zhang, Hai Hu, Guangliang Wen

Patent number: 10313154Abstract: An I/O board of a VXLAN switch searches out a layer 3 entry; when an egress port in the layer 3 entry is a VXLAN tunnel port, modifies a source MAC address of the packet into a gateway MAC address of the VXLAN switch, modifies a destination MAC address of the packet into a MAC address in the layer 3 entry, and sends the packet to a fabric board of the VXLAN switch. The fabric board determines to perform layer 2 forwarding for the packet, searches out a MAC entry, and when an egress port in the MAC entry is a VXLAN tunnel port, sends the packet to an I/O board associated with the egress port in the MAC entry.
