Embodiment 1

[0063] Embodiment 1 of the present invention describes an interface system, such as figure 1 As shown, it is a schematic structural diagram of the interface system, and the system specifically includes: a packet receiving thread 101, a packet processing thread 102, a packet sending thread 103, a physical interface 104, a logical interface 105, and a virtual interface 106, wherein:

[0064] The quantity of described physical interface 104 is at least one, and at least one physical interface 104 in the interface system forms the physical interface layer, and each physical interface in the physical interface layer is the hardware interface that does not have forwarding property; The quantity of described logical interface 105 is At least one, at least one logical interface 105 in the interface system constitutes a logical interface layer, the number of logical interfaces in the logical interface layer can be set according to actual needs, that is: the relevant resources reserved f...

Embodiment 2

[0079] In the scheme of Embodiment 2 of the present invention, such as figure 2 As shown, assume that there are 12 physical interfaces in the physical interface layer, respectively labeled as G1 / 1, G1 / 2, G1 / 3, G1 / 4, G2 / 1, G2 / 2, G2 / 3, G2 / 4, Ethernet interfaces of G3 / 1, G3 / 2, G3 / 3, G3 / 4, where the labels are G1 / 1, G1 / 2, G1 / 3, G1 / 4, G2 / 1, G2 / 2, G2 / 3 Establish a mapping relationship with the 8 physical interfaces and logical interfaces of G2 / 4. The 4 physical interfaces labeled G3 / 1, G3 / 2, G3 / 3 and G3 / 4 are in the idle state, and can be configured according to actual needs. Logical interface for mapping relationships.

[0080] The logical interface layer has 6 logical interfaces, which are layer 2 interface, layer 3 interface, monitoring interface, virtual line interface, device interconnection interface and aggregation interface. The aggregation interface can be used as layer 2 interface, layer 3 interface, monitoring interface, Logical interfaces such as virtual line interfac...

Abstract

The invention discloses an interface system and a method for processing data packets. The interface system is deployed in multiple layers, and the forwarding attributes configured on the physical interface in the prior art are separated from the physical interface. A logical interface configured with forwarding attributes is added on the interface to realize the receiving, sending, and logical processing of data packets. Since the number of logical interfaces and configured forwarding attributes can be dynamically adjusted according to actual needs, the solution of the embodiment of the present invention It can increase the flexibility of interface technology deployment at the physical level, and to a certain extent, remove the limitation on the number of interfaces, and improve the scalability of interface deployment.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an interface system and a method for processing data packets. Background technique [0002] Interface is the basic component of online network security equipment, and its organizational form and framework design are of great significance to online network security equipment. At present, the organization form of interfaces in online network security devices is to deploy a single interface processing layer on the device, and directly configure forwarding attributes, such as IP addresses and VLAN numbers, on physical interfaces (such as Ethernet interfaces). When a data packet is received on the physical interface, the data packet will be forwarded according to the forwarding attribute configured on the physical interface. For example, if the forwarding attribute configured on a physical interface is a VLAN number, when the physical interface receives a data packet, it will m...
