In the method in the embodiment of the present invention, because a root node configures different control VLANs for any two rings that have an adjacent edge in an area, different control VLANs are used to transmit a protocol packet in a ring that has its own control VLAN configured. The method and system may be applied to a ring network of a metro Ethernet to provide multi-path protection and implement rapid convergence of service switchover. In addition, a network topology structure is not limited to a network topology with a single ring or only two intersecting points, and may be applied to all network topology situations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Packet processing method and system","description":"Embodiments of the present invention disclose a packet processing method and system.
