Problems solved by technology

[0003] However, the current large-scale networks are all three-layer networks. The shortcomings of the existing technology mainly include two aspects. One is that mirrored packets can only pass through the two-layer network and cannot pass through the t

Example Embodiment

[0021] figure 2 The network system 100 of the present invention and its remote mirroring implementation method are disclosed. The network system 100 includes: a source device 1, a destination device 2, and a three-layer network 3 between the source device 1 and the destination device 2. The source device 1 is provided with a source port 11 for copying messages and an egress port 12 for mirroring the messages of the source port 11 to form mirrored messages. The mirrored message is tagged on the outgoing port 12, so that the mirrored message can be transmitted to the destination device 2 through the Layer 3 network 3. The destination device 2 is provided with a destination port 21 for transmitting mirrored packets.

[0022] In the embodiment shown in the present invention, the three-layer network 3 is a multi-protocol label switching (MPLS) network. On the source device side, the source device 1 mirrors the message of the source port 11 to the out port 12 configured with the MPLS...

Abstract

The invention discloses a network system and a remote mirroring realization method thereof, which are used for passing through a three-layer network to transmit a mirrored message. The network system comprises source equipment, destination equipment and the three-layer network positioned between the source equipment and the destination equipment, wherein the source equipment is provided with a source port for copying a message and an output port for mirroring the message of the source port to form the mirrored message; and the mirrored message is labeled on the output port and transmitted to the destination equipment by the three-layer network. By such settings, the mirrored message is labeled on the output port and further can be transmitted by the three-layer network, so the practicability and flexibility of remote mirroring are greatly improved.

Description

【Technical field】 [0001] The invention relates to a network system which is applied in an Ethernet network environment and uses remote mirroring to mirror the data flow of a remote port to a local network system and a method for realizing the remote mirroring. 【Background technique】 [0002] Existing remote mirroring implementations generally work on the second floor. The advantage is that the configuration is simple and effective. For example, Cisco's Remote Switched Port Analyzer (RSPAN) technology and H3C's remote destination mirroring technology are both remote mirroring of this type. . Please refer to figure 1 As shown, the working principles of the above two technologies are basically the same, and the description is as follows: On the source device side, the source device is responsible for copying the packets of the source port, broadcasting them in the remote mirroring VLAN, and transmitting them to the intermediate device or the destination device. If there are m...
