Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0023] The embodiment of the present invention realizes the hot plugging of the router line card by separating the software configuration of the line card from the physical application of the configuration in the actual line card, and separating the existence of the line card from the activation of the line card.

[0024] Among them, separating the software configuration of the line card from the physical application of the configuration in the actual line card means that the user can install a virtual line card in a certain slot through software commands without inserting the physical line card...

Abstract

The invention provides a realization method of the hot swap of a router line card and a device thereof, wherein the method comprises building up a virtue line card on a slot of a to-be-inserted physical line card of the router and loading the virtue driving, storing the configuration information aiming the configuration of the virtue line card, loading the truth driving for the physical line card when inserting the physical line card matched with the type of the virtue line card into the slot, and issuing the configuration information of the configuration into the physical line card. The embodiment of the invention designs a virtue driving layer of the line card, and completely isolates the physical swap state of the line card and the software state of the line card, and supports the preconfigured ability, and permits users to install and configure the virtue line card when not actually inserting the physical line card.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for implementing hot plugging of router line cards. Background technique [0002] In the currently most common router architecture supporting distributed forwarding, the interior of the router is usually composed of a main control board, a switching fabric and a line card (service card). The main control board is responsible for the management of the entire device and the collection and calculation of routes, and sends the calculated forwarding table to each line card; and each line card independently routes and forwards the message according to the saved routing forwarding table and business processing; the switching structure provides internal switching and communication capabilities between the main control board and the line card. [0003] In order to ensure the reliability of the router, most routers support the hot-swappable function of the line card. ...
