Embodiment Construction

[0026] The basic idea of ​​the present invention is to add a parameter for port aggregation, that is, the maximum number of bandwidth-aware links, the maximum number of bandwidth-aware links actually sets an upper threshold, and the upper threshold stipulates that when calculating the port aggregation rate The maximum number of member ports that can be included. When the number of member ports available for port aggregation is less than or equal to the maximum number of bandwidth-aware links, the rate of port aggregation is the sum of the rates of all available member ports; when the number of available member ports for port aggregation is greater than the maximum number of bandwidth-aware links, The port aggregation rate is the sum of the rates of the physical ports selected from all available member ports equal to the number of maximum bandwidth-aware links.

[0027] Therefore, in the present invention, when the maximum number of bandwidth-aware links is set, when the number...

Abstract

The invention relates to a port collecting speed manage system and a method for restraining the speed vibration, wherein said system comprises character manage module for storing the member port information of Trunk; the port compare module for comparing the available member port number and maximum bandwidth sensitive chain number; speed fixing module for fixing the Trunk speed via the result of port comparing module. The inventive method comprises that: obtaining the available port number of Trunk; comparing the port number with maximum bandwidth sensitive chain number; when the portable number is higher than chain number, selecting the ports at middle speed, and using the sum of port speed as the speed of Trunk. The invention can restrain the speed vibration caused by bonded physical port and debonded, to supply stable network condition.

Description

technical field [0001] The invention relates to port aggregation management technology, in particular to a port aggregation rate management system and a method for suppressing port aggregation rate oscillation. Background technique [0002] Port aggregation (Trunk) is to combine multiple physical ports into a logical port through configuration software settings, and combine the bandwidth belonging to these physical ports to provide the logical port with an exclusive bandwidth that is several times that of each physical port. . The physical ports bound together are called port aggregation member ports. Users configure logical ports to implement various routing protocols and MPLS (Multiprotocol Label Switch) / VPN (Virtual Private Network) All the configurations of the port aggregation will eventually be transformed into the configuration of each member port of the port aggregation. [0003] The main function of port aggregation is to bind multiple physical links into a logica...
