Description
Technical field
The utility model relates to network system architecture, especially a kind of double-core three-layer network system architecture.
Background technology
Traditional single core double layer network framework is applicable to general mininet, i.e. Access Layer, core layer.This single core network configuration shortcoming is that user's access amount is few, system processing power limits to some extent, every platform networking machine all needs physical circuit and core to hand over machine to interconnect mutually, line efficiency is low, and user concurrent access amount of information disposal ability is not enough, core engine load weight, all services need be processed, the non-constant of redundancy, later maintenance difficulty, the system expandability is low.
Utility model content
In order to solve the problem, the utility model provides a kind of double-core three-layer network system architecture simultaneously meeting modern large and medium-sized network.
The technical solution of the utility model is:
A kind of double-core three-layer network system architecture, intranet is connected with fire compartment wall respectively with internet, and fire compartment wall is connected with core layer, and core layer comprises two core switch, also comprises Access Layer, convergence-level simultaneously; Convergence-level comprises multiple stage convergence switch, Access Layer comprises multiple stage access switch, two core switch of described core layer are connected with every platform convergence switch of convergence-level respectively, the access switch that the convergence switch of convergence-level is corresponding with Access Layer connects, and every platform access switch is connected with enterprise customer respectively.
Two core switch of core layer adopt dual link to connect, and core layer adopts HSRP agreement.
The multiple stage convergence switch of convergence-level, convergence-level switch divides the separation that VLAN realizes broadcast domain; Convergence switch is connected with two core switch respectively, uses RSTP agreement between convergence-level, core layer, specifies two three layers of core switch to be respectively Root Bridge and backup root bridge.Access Layer comprises multiple stage access switch, and access switch is connected with convergence switch.
So-called three-tier architecture refers to: Access Layer, convergence-level, core layer, convergence-level is added relative to two-tiered structure, first zones of different Network Separation is opened as Physical Extents by convergence-level, macroreticular is changed into little network, relatively convenient management, even if wherein a convergence goes wrong and also can not have influence on entirety, also the technical configuration such as handlebar All Policies, Flow Control, VLAN is in convergence-level, core only exchanges, and so greatly alleviate the pressure of core switch, overall network performance is guaranteed.
No matter be Intranet or Internet, all by two core switch of fire compartment wall access core layer, be respectively on switch A and switch b, two three layers of core switch are respectively Root Bridge and backup root bridge, can realize the Fast Convergent of link, dual link is adopted to connect between core switch, object improves the link bandwidth between core switch, and redundancy, backup each other, reaches the load balancing of data, configured port polymerization between two three-tier switch, to improve bandwidth.
The multiple stage convergence switch of convergence-level represents different business company or different floor switch respectively, every platform convergence switch is connected respectively on two core switch by two up links, transfer of data, process can be carried out in optimum selecting path during data processing, shorten network response time, under each convergence-level switch, be connected to N platform access-layer switch.The separation of VLAN realization to broadcast domain is divided in convergence-level, such as wherein two switches are two convergence switches of same operation layer, divide VLAN time by its stroke in same VLAN section, the broadcast of a VLAN inside and unicast traffic all can not forward in other VLAN, thus contribute to the fail safe controlling flow, minimizing equipment investment, simplified network management, raising network, the generation of effective control broadcast storm, can also be used for the mutual access between different department in net control, different website.
System later maintenance convenience, if wherein a core switch breaks down, another can bear the basic serviceability of all-network, if convergence-level, access-layer switch break down, the operation of the switch of other regions or business can not be affected, reduce switch to break down the impact brought, ensure that network can run.
Compared with prior art, the beneficial effects of the utility model are:
Overall network extensibility is better, meets the application of different enterprise crowd at any time, and concurrent user's access amount is large, and the process information response time is short, and network system stability is strong, and reliability is high, later stage system maintenance easy.If wherein a core switch breaks down, another can bear the basic serviceability of all-network, if convergence-level, access-layer switch break down, can not affect the operation of other switches, reduce switch to break down the impact brought, can ensure that network can run.
Accompanying drawing explanation

Embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
As shown in Figure 1, the intranet 1 of double-core three-layer network system architecture is connected with fire compartment wall 3 respectively with Internet 2, and fire compartment wall 3 is connected with core layer, and core layer comprises two core switch 4, also comprises Access Layer, convergence-level; Convergence-level comprises multiple stage convergence switch 5, Access Layer comprises multiple stage access switch 6, two core switch 4 of described core layer are connected with every platform convergence switch 5 of convergence-level respectively, the access switch 6 that the convergence switch 5 of convergence-level is corresponding with Access Layer connects, and every platform access switch 6 is connected with enterprise customer 7 respectively.
Core layer comprises two core switch 4, and double-core backups each other, and two core switch 4 adopt dual link to connect, core layer adopts HSRP agreement, realize the backup policy of upper level link, configured port polymerization between two three-tier switch, to improve the load balancing that bandwidth reaches data.
Convergence-level comprises multiple stage convergence switch 5, and convergence-level switch divides the separation that VLAN realizes broadcast domain; Convergence switch 5 is connected with two core switch 4 respectively, uses RSTP agreement between convergence-level, core layer, specifies two three layers of core switch to be respectively Root Bridge and backup root bridge.
