Abstract: Disclosed are a routing adjustment method, apparatus, and an electronic device. In an example, if congestion occurs on the first path with the highest forwarding weight, i.e., the optimal forwarding path for data stream, instead of directly abandoning the first path, the forwarding weights of the first path and other non-optimal path(s) (other path(s) with forwarding weight(s) lower than that of the first path) are dynamically adjusted, so that the data stream intended to be forwarded through the first path is forwarded through a combination of the first path and other path(s), thereby improving link bandwidth utilization.

Abstract: Provided are methods and apparatuses for updating a route. In the present disclosure, when an access device receives a first host route and a first sequence number sent by a BGP peer of the access device, regardless of the value of the first sequence number, the first host route is used as a route used by the access device to forward data to a target host, and a recorded first ARP entry corresponding to the target host is deleted, so as to trigger the BGP peer of the access device, for example, a convergence device, to withdraw host routes associated with the first ARP entry based on the existing route withdrawal mechanism.
