One: Development trend of the market of access network
The development of demand and communication becomes two major motive power that the market of access network develops. The new business including video business is employed to inserting the demand for the bandwidth bigger and bigger fast, on the other hand the development of communication has offered the strong assurance for demand that the high bandwidth inserted. The two complement each other, become two major driving force that the market of access network develops.
On the basis of the experience of the access network, especially special net construction for many years, the beacon network thinks the access network, especially VIP customer’s special net market has the following several development trend:
Broad band: The VIP customer who regards proposing the speed with gold shield network as representatives raises speed, the large bandwidth business that video business of controlling etc. and network of stemming from high clear video conference, video of driving force are stored,etc.. The beacon network thinks the development of the special network is sure to insert developing towards direction in which the even higher bandwidth of 10M bandwidth inserts from 2M bandwidth several years ago, and the beacon network thinks recent special net construction will rely on SDH and PDH resources, can vitalize the operator and leave resources unused on one hand, on the other hand SDH and PDH technology still has other advantages of high security,etc. that other technology can’t be compared.
Standardization: With before there emerge in an endless stream is various access network technology,apply solution on is it privately owned in various in VIP customer’s special network getting getting more more extensive too, but the beacon network thinks the development trend of the access network will stridden forward in the standardized direction. Only standardization could make every accession equipment manufacturer’s intercommunication become possible; Only standardization could make apparatus development and operation have space lowering costs effectively. As the forerunner of respect of standard formulation, the beacon network has already stood in the forefront of the industry, have made three international standards and numerous and domestic and sector standards including X.86 in formulation and leading factor. Beacon network development of access network equipment based on international and domestic too and the intersection of trade and relevant standard come, implement.
All actinic: Enter copper, it retreats to be one main trend that can’t reverse only, all actinic to can reduce, network cost effectively not merely, save resources, because the optical signal one is difficult to be analytic can further strengthen the business security of the access network. On the basis of all mere development trend, the beacon network firsts elect VIP customer’s special network solution of E1PON passive optic fibre in the industry.
Exchange management: The access network is already larger and larger in scale, more and more complicated, how to manage and maintain is a big problem that an access network develops. The network management that the beacon network can can think the access network in North Korea, exchange the direction development of the network management, the access network technology and equipment not exchanging the network management can not be rising. The beacon networks have all inherited the thinking of product development of the network management of comprehensive network management, the whole network all the time, the major access network products include OL200 optic fibre transceiver access platform, B2000 agreement converter platform, the comprehensive access platform of B3000 many business adopts the network management of the whole network and way to exchange network management to develop.
Because of the understanding of access network, especially special network development trend, the beacon network has put out 3E solution of new generation on the basis of much business integrated service access platforms B3000.
Two: 3E solution of new generation of the beacon network
In order to agree with the development trend of the access network, the beacon network Co., Ltd. of Wuhan puts out 3E solution of new generation, 3E solution of new generation is EOS Ethernet Over SDH respectively , EOP Ethernet Over PDH , and E1PON E1 Passive Optical Network Group’s network scheme. This text has carried on the detailed introduction to 3E solution of new generation, and explained the advantages of different schemes systematically.
2.1 EOS Ethernet Over SDH Solution
Traditional EOS Ethernet Over SDH The solutions mostly adopt HDLC to encapsulate, and it is not a passway Contact method to generally adopt, that is to say every 155M SDH interface can only be used by a user, causes the great wasteful use of resources. EOS solution of new generation that the beacon network puts out adopts the passway design plan, greatest support 8 VCGs, namely each EOS unit greatest support and eight routes of VIP customer’s business are inserted, and every No. can flexible to dispose bandwidth according to demand in business, one prominent advantage whether network upgrade transform, only need to revise the software and dispose realizing it is upgraded that the bandwidth not decreasing the business is smooth.
EOS solution of new generation of the beacon network is available to adopt LAPS and GFP standard to encapsulate the agreement, support VCAT and LCAS agreement, EOS accession equipment that the standardized design is the beacon network can be with the basic reason of major apparatus intercommunication of MSTP manufacturer.
Beacon solution, EOS of network, can cooperate with the intersection of MSTP and the intersection of transmission equipment and the intersection of group and network, can also independent the intersection of group and network realize the integrated service is inserted, Fig. 1 is a topological picture of the single group’s network of EOS solution. When the beacon network EOS apparatuses mix group’s network with MSTP transmission equipment, EOS apparatus can be put inserting the computer lab as VIP customer’s business accession equipment at first, realize that seals VIP customer’s Ethernet business of many ways to put into the function that SDH conveys the network; EOS apparatus can put on computer lab of assembling, assemble every business the intersection of Ethernet and data and form the intersection of GE and the intersection of dataflow and first line of a couplet, get the intersection of user and centre after exchanging backplates to deal with of point secondly; The beacon network EOS solution can solve MSTP apparatus unit bandwidth and assemble the defect of less number of users finally, if the bandwidth of the Ethernet board card 622M of a MSTP can only assemble 24 users, and the beacon network EOS solution 155M bandwidth can assemble 32 users, thus the customer service which can assemble in big expansion MSTP apparatus is counted.

2.2 EOP Ethernet Over PDH Solution
EOP Ethernet Over PDH The solution has fully transmitted Ethernet data by leaving E1 resources unused in the operator. EOP solution of new generation of the beacon network adopts GFP and LAPS available standard and becomes frame ways, and realize by VCAT and LCAS agreement many ways E1 truss up and transmit Ethernet data, thus has overcome the traditional EOP solution and encapsulated the shortcoming that the not high and many manufacturer of efficiency does not interflow. The beacon network group’s network of EOP solution of new generation is shown as in Fig. 2.
This scheme has fully utilized inserting E1 left unused in computer lab to transmit resources: User’s nodal in branch Ethernet data extend to inserting the computer lab through the optic fibre, then EOP small-scale desk-top accession equipment adopt GFP/LAPS encapsulate agreement seal, put business datum, Ethernet of user, into the intersection of N and *E1 transmit in the passway conveying by the intersection of SDH and transmission net to, remitting Gather the computer lab. Assemble computer lab, abandon the intersection of N and whom *E1 is wire that traditional association transfer to, assemble way, adopt standard the intersection of SDH and the intersection of 155M and the intersection of optic fibre and way of interface assemble every nodal business, every nodal business assembled through 155M SDH mere interface is connected to user’s centre through GE interface after the high capacity does not have exchange backplate hindered and had a match that is dealt with. Because the whole network adopts standardized agreement handling, can adopt apparatus intercommunication of manufacturer of the standard agreement with any.
The network network of group of the whole EOP solution can be unified the network management by the network management centre. The network management centre manages to B3100 many business comprehensive access platform apparatuses which assembles the computer lab through ways such as Telnet, SNMP,etc., and manage EOP miniaturization accession equipment and user’s nodal optic fibre transceiver which insert the computer lab through this apparatus, purpose to realize network management of the whole network and comprehensive network management.

2.3 E1PON E1Passive Optical Network Solution
It is in short more supply that the access point of the VIP customer of centre of city causes optic fibre resources intensively at present, lay the time consuming strength of dawdling of optic fibre again, technology such as E/GPON, WDM reply and use a plurality of business on an optic fibre in order to save optic fibre resources in order to solve this contradiction. But E/GPON, WDM two technology insert in the field having their defects in the intersection of operator and VIP customer, mainly showing in the following aspects: Expecting very much to security such as the VIP customer such as bank network, believe in the way replied and used in time based on SDH, do not believe in by way of G/EPON taking network technology very much as kernel very much; Though WDM saves on optic fibre resources certainly, the cost fabrication cost of apparatus is very high, not suitable to be the access way of VIP customer’s access network.
In order to solve the above-mentioned contradiction, the introduction E1 PON E1 Passive Optical Network of new generation that the beacon network innovates in the industry on the basis of the comprehensive access platform of many business Solution. The beacon network E1 PON solution has adopted the design philosophy of PON system, has saved operator’s relaying optic fibre optical cable investment, but the adoption innovating again replies using TDM time because of SDH technological kernel The mechanism, but not the technological kernel based on Ethernet of EPON system, it is the high dependability, outstanding solution that the VIP customer of high security inserts business optic fibre. Fig. 3 is that E1 PON solution contrast with tradition only carrying machine solution and pursue.
Fig. 3: E1 PON solution contrasts with only carrying machine scheme of the tradition and pursues
Can be found out from Fig. 3, only the carrying machine is compared with the tradition, E1 PON solution has the following advantages:
1The network has terseness greatly, bring to the customer and transport the simplicity linked, transport and link the cost sparingly;
2Save a large number of relaying optic fibre resources, save the investment of optic fibre;
3Reduce by a large number of E1, beat line, work, saving time saves effort, has reduced the trouble point;
4The business born the weight of has point-to-point characteristics, have security of SDH rank.
The beacon network is regarded as the major provider of VIP customer’s special network solution, all the time in order to offer the high cost performance, high dependability, the special network solution of exchanging management is the own duty. The beacon network will continue inheriting and offering the thinking of the outstanding access network solution to customer in the future, further press close to the technological development trend, further press close to customer’s demand, put out the access network solution of meeting customer’s demand.
