Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0043] The present invention sets an entry flag bit for each address in the memory resource storing the dynamic entry, which is used to distinguish between the dynamic entry and free memory, and traverses the memory resource after receiving a request message displaying the dynamic entry in the memory resource , and judge whether the current address has an entry according to the entry flag bit of each address, if so, read the current entry content, otherwise do not process, after the traversal, display all the read entry contents.

[0044] Referring to Fig. 5, the present invention provides a method for displaying dynamic entries, first performing the initialization steps:

[0045] Step 101: first create a resource information table to store resource information allocated by the system;

[0046]...

Abstract

The invention provides a method and a device for displaying dynamic page table, which belongs to the field of data communications. To solve the problem incapability of well displaying the dynamic pager table of data plane and complicated maintenance of page table in the prior art, the invention provides a method for displaying dynamic page table, which includes setting a marker bit for the page table. The invention includes ergodic memory resource and steps of displaying the contents in the page table. Besides, the invention also provides a device for displaying the dynamic page table, which includes an initialization module, an ergodic module and a displaying module. By applying the technical proposal of the invention, the system stability is greatly improved with little effect on the maintenance of the dynamic page table while rendering a highly-performed expandability of the dynamic page table entry.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for displaying dynamic entries. Background technique [0002] The purpose of distributed network devices is to be able to forward packets, and how to forward packets is determined by the table entries of the network devices. The part of the network device responsible for generating entries is called the control plane, and the part responsible for forwarding is called the data plane (also known as the forwarding plane). The control plane calculates and generates entries according to user configurations or protocols, and the forwarding plane forwards packets based on the generated entries. Table entries are divided into static entries and dynamic entries. Dynamic entries refer to entries that consume memory resources that change with changes in user configuration. The more user configurations, the more memory resources are consumed. How to manage dynamic entr...
