【摘要】：二層交換機(jī)能夠有效的隔離沖突域,但是它并不能有效的處理好廣播域?qū)W(wǎng)絡(luò)的影響。當(dāng)網(wǎng)絡(luò)中的主機(jī)數(shù)量很多時(shí),網(wǎng)絡(luò)吞吐量會(huì)大大降低,報(bào)文轉(zhuǎn)發(fā)率急劇減小,網(wǎng)絡(luò)帶寬得不到充分利用,安全方面可能也會(huì)存在一些問(wèn)題。VLAN技術(shù)能很好的解決上述問(wèn)題。VLAN,虛擬局域網(wǎng),可跨不同網(wǎng)段。一個(gè)VLAN就是一個(gè)邏輯廣播域。VLAN可以覆蓋多個(gè)網(wǎng)絡(luò)設(shè)備。VLAN將網(wǎng)絡(luò)設(shè)備劃分成多個(gè)不同的網(wǎng)段。VLAN技術(shù)在實(shí)際應(yīng)用中倍受青睞,但在一般的網(wǎng)絡(luò)組網(wǎng)方式中,VLAN的通信方式對(duì)IP地址資源浪費(fèi)比較多。隨著互聯(lián)網(wǎng)的快速發(fā)展,IP地址資源越來(lái)越緊張,在這種情況下,為了緩解IP地址資源的緊張形勢(shì),Super VLAN的概念被提了出來(lái)。Super VLAN又稱VLAN聚合或者超VLAN。一個(gè)Super VLAN可以包含多個(gè)Sub VLAN。一個(gè)SubVLAN是一個(gè)獨(dú)立的廣播域。Sub VLAN間的主機(jī),二層隔離,三層互通。SubVLAN可以加物理端口,Super VLAN不可以加物理端口。Super VLAN是否處于UP狀態(tài),取決于它的Sub VLAN是否UP。Super VLAN技術(shù)中涉及到ARP代理功能。Super VLAN技術(shù)達(dá)到了節(jié)省IP地址資源的目的。Super VLAN技術(shù)能有效解決網(wǎng)絡(luò)環(huán)路的問(wèn)題,編址靈活,保證網(wǎng)絡(luò)良好的吞吐量,能消除子網(wǎng)間的差異,使網(wǎng)絡(luò)升級(jí)更容易。這些優(yōu)點(diǎn)使得Super VLAN在實(shí)際的網(wǎng)絡(luò)應(yīng)用具有很大的優(yōu)勢(shì),它在實(shí)際中應(yīng)用的層面也越來(lái)越廣。但是僅僅從理論上論證是單薄的,上述結(jié)論還需要在實(shí)際應(yīng)用中去論證,本文便是從實(shí)際應(yīng)用中出發(fā),對(duì)Super VLAN功能進(jìn)行了軟件實(shí)現(xiàn),將此功能實(shí)際應(yīng)用在網(wǎng)絡(luò)設(shè)備中,并在實(shí)際的網(wǎng)絡(luò)組網(wǎng)中,搭建測(cè)試環(huán)境,進(jìn)行了完備的功能測(cè)試,論證上述理論的正確性。
[Abstract]:Layer 2 switch can effectively isolate the conflict domain, but it can not deal with the impact of broadcast domain on the network effectively. When the number of hosts in the network is large, the network throughput will be greatly reduced, the packet forwarding rate will be reduced sharply, and the network bandwidth will not be fully utilized. Security aspects may also exist some problems. VLAN technology can solve the above problem. VLAN, virtual local area network, can span different network segments. A VLAN is a logical broadcast domain. VLAN can cover multiple network devices. VLAN divides the network equipment into multiple different network segments. VLAN technology is very popular in practical applications. However, in the general networking mode, the communication mode of VLAN is more wasteful of IP address resources. With the rapid development of the Internet, the resources of IP address are becoming more and more tight. In this case, the concept of Super VLAN has been put forward in order to alleviate the shortage of IP address resources. Super VLAN is also called VLAN aggregation or super VLAN. A Super VLAN can contain multiple Sub VLANs. A SubVLAN is a host between independent broadcast domains. Sub VLAN, two layers are isolated, three layer interworking. SubVLAN can add physical port. Super VLAN can not add physical port. Super VLAN is in up state. Depending on whether or not its Sub VLAN involves ARP proxy function. Super VLAN technology can save IP address resources and can effectively solve the problem of network loop, address flexibility, and ensure good throughput of the network, which depends on whether its Sub VLAN technology involves the ARP agent function, the Super VLAN technology has achieved the goal of saving IP address resources, and the technology of Super VLAN can effectively solve the problem of network loop. Can eliminate the difference between subnets, make network upgrade easier. These advantages make Super VLAN have great advantages in practical network applications. However, the theoretical proof is thin, and the above conclusions need to be demonstrated in practical application. This paper is based on the practical application, and implements the Super VLAN function by software, and applies this function to the network equipment. In the actual network, the testing environment is set up, and the complete function test is carried out to prove the correctness of the above theory.
