Problems solved by technology

Then, for example, in order to obtain the ARP information of all connected users, the number of packets that the layer-3 switch needs to send is: the number of VLANs under VLAN aggregation × the number of connected users; however, a user only belongs to One VLAN, therefore, there will be ((the number of VLANs under VLAN aggregation-1)×the number of all connected users) messages that are invalid messages, which will seriously affect the processing performance of the Layer 3 switch, and these invalid messages Packets also place a processing burden on the network and other devices in the network

Embodiment 1

[0027] see figure 1 , a method for sending a message, the method is as follows:

[0028] Step 101: when sending a message, look up the correspondence between the IP address information and the virtual local area network according to the destination IP address of the message;

[0029] Step 102: If the corresponding relationship between the IP address information and the virtual local area network is searched according to the destination IP address, the virtual local area network corresponding to the destination IP address is obtained, and the message is sent to the virtual local area network;

[0030] Step 103: If the search module searches for the corresponding relationship between the IP address information and the virtual local area network according to the destination IP address and cannot find the virtual local area network corresponding to the destination IP address, it sends a message to all virtual local area networks.

[0031] In the embodiment of the present inventio...

Embodiment 2

[0033] see figure 2 , is a schematic diagram of the networking of the aggregated VLAN network connected by the three-layer switch corresponding to the embodiment of the present invention; figure 2 The shown aggregated VLAN network includes three virtual local area networks, namely VLAN 10, VLAN 20 and VLAN 30, that is, VLAN 10, VLAN 20 and VLAN 30 are all added to aggregated VLAN 100, and aggregated VLAN 100 is correspondingly configured with VLAN IF ( VLAN 10, VLAN 20 and VLAN 30 and aggregate VLAN 100 are linked by Layer 3 switches 2, 3, 5 and 1 respectively.

[0034] In the embodiment of the present invention, the network administrator of the aggregated VLAN network may statically configure one or more corresponding IP network segments for the aggregated VLAN network and each virtual local area network in the aggregated VLAN network, wherein the IP network segment corresponding to the aggregated VLAN network Contains the IP network segments corresponding to each virtual ...

Embodiment 3

[0119] see Figure 8 , a switch, the switch is specifically the same as the three-layer switch in the method embodiment 2, including: a search module 601 and a transmitter 602;

[0120] The search module 601 is configured to search the correspondence between the IP address information and the virtual local area network according to the destination Internet Protocol IP address of the message when the message is sent;

[0121] The transmitter 602 is used to obtain the virtual local area network corresponding to the destination IP address if the search module 601 searches the corresponding relationship between the IP address information and the virtual local area network according to the destination IP address of the message, and sends the message to the virtual local area network. When the corresponding relationship between the IP address information and the virtual local area network cannot be obtained by searching the destination IP address of the message and the virtual local...

Abstract

The invention discloses a method for sending message and a switch, and belongs to the technical field of computer networks. The method comprises the following steps of: when the message is sent, searching a corresponding relationship between Internet protocol (IP) address information and a virtual local area network (VLAN) according to the destination IP address of the message; and if the VLAN corresponding to the destination IP address is acquired according to the corresponding relationship between the IP address information and the VLAN searched according to the destination IP address, sending the message to the VLAN, otherwise, sending the message to all VLANs. According to the technical scheme, the sending quantity of the invalid message can be effectively reduced, the sending performance of the message under a gathered VLAN scene is improved, and the influence of the invalid message on the whole VLAN is reduced.

Description

technical field [0001] The present invention relates to the technical field of computer networks, in particular to a method and a switch for sending a message. Background technique [0002] Currently, a Layer 3 switch is usually used to speed up data exchange within a VLAN (Virtual Local Area Network, virtual local area network) network. The Layer 3 switch can be used as a gateway of the user to realize high-speed forwarding of Layer 3 data packets in the OSI (Open Systems Interconnection Reference Model, Open Systems Interconnection Reference Model) network model. [0003] Specifically, in order to realize the high-speed forwarding of Layer 3 data packets, when building a VLAN network, the Layer 3 switch needs to configure the VLAN IF (logical port of the virtual local area network) corresponding to each VLAN network, and allocate the VLAN IFs for the configured VLAN IFs. A corresponding IP (Internet Protocol, Internet Protocol) network segment, and each assigned IP networ...
