Abstract
The invention provides a forwarding database optimal configuration method for switches. The method comprises the following steps: according to requirements of a user, function points that each database item needs to apply are determined; according to the function points that each database item needs to apply, each database item is endowed with a corresponding weight; according to the weight of each database, the proportion of the weight of each database that accounts for the value of the total weight is calculated; and according to the above proportion, size of each database is distributed again. According to practical application requirements of a user, optimal configuration is carried out on forwarding databases of a switch. Size of each database of a switch is reasonably distributed effectively according to a practical application scene of a user.
Description
[technical field]
The present invention relates to the switch network communications field, relate in particular to the Optimal Configuration Method that the unification of switch is transmitted.
[background technology]
Existing switch has various transmitting to forwarding behavior, such as L2 table, and L3 table etc.L2 table and L3 table are by unified table as container, and the memory size being required to be in table configures.Generally, existing memory configurations scheme is all when initialization, to give L2 table, and the fixed size of L3 table, after product export, generally can not be optimized configuration.
Thereby existing switch has been specified after corresponding list item size in research and development side, list item is also substantially fixing.But, for the user of final use, can not do practical application configuration according to the demand of oneself.
[summary of the invention]
The technical problem that the present invention need solve is to overcome above-mentioned deficiency, provides a kind of switch to transmit Optimal Configuration Method, and the method is according to user's practical application request and switch is transmitted and carried out practical application and distribute rationally.
For solving above-mentioned technical problem, the present invention has designed a kind of switch and has transmitted Optimal Configuration Method, and the method comprises the following steps:
Step1: according to user's demand, determine the function point that various list items need be applied, the function point that need apply according to various list items, is assigned to corresponding weights to various list items;
Step2: according to the weights of various tables, calculate the ratio that various table weights account for the value of total weight value;
Step3: according to above-mentioned ratio, redistribute the size of various tables.
The present invention is according to user's practical application request, and switch is transmitted and is optimized configuration.Effectively according to user's practical application scene, the size of the various tables of reasonable distribution switch.
[accompanying drawing explanation]
Fig. 1 is the flow chart that switch of the present invention is transmitted Optimal Configuration Method.
[embodiment]
Below in conjunction with drawings and embodiments, the invention will be further described.
The invention provides a kind of switch and transmit Optimal Configuration Method, the method is according to user's practical application request and switch is transmitted and carried out practical application and distribute rationally.
As shown in Figure 1, switch of the present invention is transmitted Optimal Configuration Method, and the method comprises:
First, according to user's demand, determine the function point that various list items need be applied, the function point that need apply according to various list items, is assigned to corresponding weights to various list items; Again, according to the weights of various tables, calculate the ratio that various table weights account for the value of total weight value; Then, according to above-mentioned ratio, redistribute the size of various tables.
In actual applications, such as, function is transmitted in a certain switch support unification, conventionally, and the unified list item that includes three kinds of large types: L2 table, L3 table, the MPLS table transmitted.In the present embodiment, exemplify transmitting of this three types, but be not limited to these three kinds, transmit.
First determine the function point of L2 table, L3 table, MPLS table, analyze the demand of the demand of various tables own and user's practical application.L2 table is the necessary list item as two layers of exchange, in view of this function point, while being assigned to L2 weights, thereby must give actual numerical value, guarantees the certain existence of L2 table.And L3 is while having its household function point, is also to exist; But when large to L3 forwarding capability demand, and multicast functionality is when be equipped with, and correspondingly gives larger weights.As for, MPLS table is similar L3 table, but the not use under many circumstances of MPLS function point, so need not minimumly guarantee.
In practice, function point is equipped with according to acquiescence and user's configuration.Such as, for L3 table, both can provide the list item of clean culture, can provide multicast list again, when user does not need multicast functionality, according to this, can join applicable size and show to L3.But when user confirms to need multicast functionality, correspondingly, L3 table can obtain larger space size.
Because transmit, distribute the weights that depend on its demand, when according to the function point of analyzing various tables, after being assigned to corresponding weights, then according to weights ratio, configure the size of various tables.
At first, according to the weights of various tables, first sum up, confirm various table occupation proportion.Such as L2 table takies weights 10, and every table weights summation of adding up is 40, and L2 table takies 25%, and the size that whole unification is transmitted is 44K, and the size requirement of L2 table is 11K.The size of the table of other kinds the like.
Due to the restriction of current chip, if transmitted after size adjustment, often need to restart, so redistributing of whole forwarding-table item is also to determine whether redistribute according to user intention.
The present invention is according to user's practical application request, and switch is transmitted and is optimized configuration.Effectively according to user's practical application scene, the size of the various tables of reasonable distribution switch.
Above-described is only embodiments of the present invention, at this, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make improvement, but these all belongs to protection scope of the present invention.
