Embodiment Construction

[0028] Since the ASIC chip inside the switch is generally an ASIC chip with only an ingress hardware table, the embodiment of the present invention adds valid egress port information to the ACL originally applied to ingress control, so as to perform the packet processing for the message to be sent out from the specified egress port. Corresponding processing, in order to realize the export control of the message.

[0029] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] figure 2 The process of realizing export control provided by the embodiment of the present invention specifically includes the following steps:

[0031] S201: The switch configures effective ingress port information, effective egress port information and processing operation information in the ACL, and inserts the configured ACL into the ingress hardware table.

[0032] In the embodiment of the present invention, in addition to conf...

Abstract

The invention discloses a method and device for realizing outlet control, which are used for solving the problem that messages cannot be accurately controlled because the messages can be only subjected to inlet control in the prior art. The method comprises the following steps of: a switchboard is allocated with effective inlet port information, processing operation information and effective outlet port information in an ACL (Access Control List), and the allocated ACL is inserted into an inlet hardware list; when receiving a message, the switchboard determines inlet port information and outlet port information of the message; and the effective input port information contained in the inlet hardware list and a determined ACL matched with the inlet port information of the message are selected form the inlet hardware list, the effective outlet port information contained in the selected ACL and a determined ACL matched with the outlet port information of the message are determined in the selected ACL, and the message is processed according to the processing operation information contained in the ACL. The method for realizing outlet control, disclosed by the invention, realizes the outlet control over the messages and improved accuracy of message control.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for realizing export control. Background technique [0002] At present, the application specific integrated circuit (Application Specific Integrated Circuit, ASIC) chip inside the switch usually adopts the ASIC chip with only the entry hardware table, and through the access control list (Access Control List, ACL) configured in the entry hardware table. Packet entry control. [0003] Specifically, the method of controlling the ingress of packets through the ACL configured in the ingress hardware table is as follows: figure 1 shown. figure 1 The process of implementing ingress control through ACL in the prior art specifically includes the following steps: [0004] S101: Insert the configured ACL into the ingress hardware table, where the ACL includes: valid ingress port information, message attribute information, and processing operation information. ...
