Description
Technical field
The present invention relates to network communication technology fields, and in particular to a kind of light net based on ASON+SDH complex network mode
Network optimization method.
Background technique
In recent years, with the continuous acceleration of urban construction, regional industry production and powerline network are rapidly developed, by
Step forms the powerline network with broadband, intelligent, diversification and synthesization.Due to regional powerline network
Framework becomes increasingly complex, and the related service of carrying is more and more, how to promote the safety of powerline network, stability and can
It is currently to be suffered from a problem that by property.
For example Hefei district power communication Huawei ASON Optical Transmission Network OTN is since establishing and putting into operation for 2009, stable operation 10
As long as year, the station number being related to is up to 240, mainly by Huawei OSN3500, OSN2500, OSN1500B and Metro
1000 serial equipments composition.As network size continues to develop, intelligent net element quantity is more than 150 in the domain Huawei ASON, is more than
Master control borad bearing capacity influences Huawei's transmission ASON protection intelligent characteristic and plays, and there are some potential safety problemss.It considers simultaneously
Company, part county is connected Optical Cable with company, city and not enough enriches, and cannot give full play to the network advantage of ASON.Based on this, 2016
Year, Hefei company proposed Hefei City's ASON intelligent domain being divided into Lujiang County and the intelligent domain of Hefei City two, and domain inner tunnel business is adopted
It is protected with ASON, business realizes the protection of the whole network business full dose using SNCP sectional protection type between the domain ASON+ in domain between domain.Net
After the network even running time more than a year, Hefei intelligent domain is further divided into Changfeng County and Hefei City's intelligent domain by Hefei company.
So far, Hefei electric power Huawei transmission ASON optical-fiber network is divided into three intelligent domains, i.e. Hefei domain, Lujiang domain and length altogether
Rich domain, the whole network open intelligent characteristic network element totally 173, wherein 120, Hefei domain, 27, Lujiang domain, 26, Changfeng domain.From previous
From the point of view of networking structure and cable resource situation, dividing intelligent domain is to evade the excessive effective hand of individual domain intelligent net element quantity
Section.It includes that four Huawei, the city Xian Er ASON transmit net topology schematic diagram that Fig. 1, which gives Hefei district, simply shows conjunction in schematic diagram
Fertile urban district, Chaohu Prefecture, Changfeng County and Lujiang County part intelligent net element.It is important to note that the current Changfeng County domain ASON
Pass through SNCP channel protection ring with the domain Lujiang County ASON and the domain Hefei City ASON interconnects, to form entire Hefei district Huawei
ASON domain, as shown in Figure 2.
From figure 2 it can be seen that the Lujiang domain ASON is faded to by flag mountain, clear pass becomes and Chinese scholartree light fades to Chaohu road Bian Liangtiao
By accessing the domain Hefei ASON.It needs to be downgraded to generic link because drawing a domain it is emphasized that Lujiang fades to Taurus change routing,
It can not play the role of intelligent protection.In addition, flag mountain fade to clear pass become routing i.e. will be out of service, the former dual domain interconnection channel SNCP guarantor
Retaining ring will not exist, and be recombinated.But not in view of current Lujiang County domain and the routing of Hefei administrative region of a city linking cable resource
It is enough abundant, Lujiang change can only be faded to using Taurus and Chinese scholartree light fades to Chaohu and becomes this two routings establishment SNCP path protection again
Ring becomes by Lujiang change, Taurus change, Yun Gubian, beautiful change, Bin Hu respectively, long change of bordering on the river, clear pass becomes, Chaohu becomes, Chinese scholartree light, hut
Jiang company and Lujiang become, totally 11 websites.The SNCP looped network built up of group in this way is excessive, and number of nodes is excessive, and safety is extremely low.
In addition to this, Taurus fades to yellow village change Optical Cable and will open, if continued using the networking for dividing intelligent domain
Mode, must the downgrade processing link, to cause the waste of the cable resource.With the continuous hair of powerline network
Exhibition, the degrees of fusion of network will gradually increase between administrative region of a city and county domain, and Optical Cable will be more and more abundant between domain, and cable resource utilizes
The low problem of rate will more aobvious protrusion, cities and counties' area reliability can not also improve, and the original intention of this and optical cable construction is runed counter to.
In summary two o'clock evades the excessive method of single intelligent domain NE quantity on the domain of Lujiang by dividing intelligent domain
Trend more harm than good has been highlighted, subsequent network development plan needs are unable to satisfy, has needed to carry out network optimization adjustment.
