PACKET SENDING METHOD, DEVICE, AND SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18158272 titled 'PACKET SENDING METHOD, DEVICE, AND SYSTEM
Simplified Explanation
This patent application describes an application that provides a method, device, and system for sending packets in the field of EVPN technologies. The solution presented in this application addresses the issue of a fault in a link between a PE device and a CE device, causing the DF device to switch from the first PE device to the second PE device.
- The first PE device sends a first packet to the second PE device when switching to ensure normal forwarding of uplink traffic.
- The second PE device forwards the first packet to the CE device, allowing it to generate or update a MAC entry in time.
- The CE device can then send a packet to the second PE device based on the MAC entry, ensuring uninterrupted uplink traffic from the CE device.
Potential Applications
- This technology can be applied in Ethernet Virtual Private Network (EVPN) systems.
- It can be used in network infrastructure to ensure uninterrupted traffic flow in case of link faults.
Problems Solved
- Addresses the issue of interruption in uplink traffic when a DF device switches from one PE device to another due to a link fault.
- Solves the problem of timely generation or update of MAC entries in the CE device when switching between PE devices.
Benefits
- Ensures normal forwarding of uplink traffic from the CE device even when there is a fault in the link between PE and CE devices.
- Avoids interruption in uplink traffic and ensures continuous communication between the CE device and the network.
Original Abstract Submitted
This application provides a packet sending method, a device, and a system, and belongs to the field of EVPN technologies. In the solutions provided in this application, when a DF device switches from a first PE device to a second PE device due to a fault in a link between the first PE device and a CE device, the first PE device may send a first packet to the second PE device, so that the second PE device forwards the first packet to the CE device. Therefore, the CE device may generate or update a MAC entry in time based on the first packet forwarded by the second PE device, and may send a packet to the second PE device based on the MAC entry. In this way, the second PE device that switches to the DF device may forward the packet from the CE device, so that normal forwarding of uplink traffic sent from the CE device can be ensured, and interruption of the uplink traffic of the CE device can be avoided.
