A large-angle sloping roof steel structure connected to a main body structure, including: an intermediate platform, inclined main supporting steel columns circumferentially connected at four corners of the intermediate platform, constructing steel columns and wind-proof surrounding beam connected between top ends of the inclined main supporting steel columns, where roof purlin are connected between the adjacent inclined main supporting steel columns at intervals. The invention provides a top-down inverted construction method for a large-angle sloping roof with a steel structure as the main structural form. By using the method, the operation safety of an inclined main stressed vertical member during the installation process can be ensured, and the investment of supporting measures is reduced by preferentially installing the intermediate platform, thus effectively ensuring the installation progress, quality and safety of the sloping roof steel structure. The present invention can be widely applied to sloping roof construction.

Large-angle sloping roof steel structure and construction method thereof

A first Virtual Device (VD) of a first member device connects to a first VD of a second member device via a stacking link that is established between the first member device and the second member device. A VD number of the first VD in the first member device is the same as that of the first VD in the second member device. When a unicast packet is received via a service port, the first VD of the first member device searches in a forwarding table of the first VD in the first member device. When the unicast packet is to be forwarded to another member device the search of the forwarding table, the first VD of the first member device forwards the unicast packet via the stacking link.

Forwarding packet in stacking system

In a method for forwarding a packet, a physical forwarding unit receives a data packet, may find a first subnet route based on a destination IP address of the data packet, and forwards the data packet to a virtual forwarding unit via an output interface of the first subnet route. The virtual forwarding unit receives the data packet may find a first host route based on the destination IP address of the data packet, and forwards the data packet based on the first host route.
