Title: Processing method and apparatus based on link error code
Inventor: WANG JIUMING
IPC: H04L45/247
Filed: 2020-05-30
Abstract: Disclosed are a processing method and apparatus based on a link error code. A network device can report, to a controller, an error code rate of an egress port, for sending data traffic, on the network device, so that the controller can collect error code rates of all egress ports on one transmission path sending data traffic and can accumulate the error code rates, thereby obtaining a cumulative error code rate of the transmission path. In this way, the controller can determine, according to the cumulative error code rate of the transmission path, whether to switch a service flow on the transmission path to any other transmission path. Therefore, the controller can switch a service flow transmitted on a transmission path with an excessive cumulative error code rate to any other transmission path with a relatively low cumulative error code rate for transmission, thereby avoiding the use of a multi-hop path with a severe cumulative error code rate to forward a service flow, and improving the stability of service flow transmission.

Title: Use of multi-element random copolymer in improving phase state structure and phase state stability of polyester/styrenic resin alloy
Inventor: DUAN HAO
IPC: C08L25/14
Filed: 2020-06-20
Abstract: The use of a multi-element random copolymer in improving the phase state structure and phase state stability of a polyester/styrene resin alloy or the use of the multi-element random copolymer in preparing the polyester/styrene resin alloy. The multi-element random copolymer is formed by copolymerizing an aromatic vinyl monomer, an acrylonitrile monomer and a glycidyl methacrylate. As a special compatibilizer for polyester/styrene resin alloys, the copolymer can be blended with other raw materials, and extruded and granulated, such that a polyester/styrene resin alloy with an excellent phase state structure and phase state stability can be prepared simply, effectively, conveniently and cost-effectively. While maintaining excellent mechanical properties, such an alloy has special effects such as repeatable processing, an excellent multiaxial impact resistance, and a low notch sensitivity, which are all due to the phase state stability, and the application fields of such an alloy can thus be broadened.
