The birth of a new technology is inseparable from influence of the great environment of the market, one that is with firm network broadband IPTV market before and after 2005 is burning hot to expedite the emergence of one grade of ether CarrierEthernet of telecommunication Technology is similar, the market of movement broadband beginning to enter high-speed development period in 2007 generates a key impact on birth of PTN. On CE and PTN requirement in telecommunication grade QoS is similar, all a kind of application in one grade of land networks of city of telecommunication of ether technology. But PTN technology increases and moves the unique demand born the weight of, includes supporting PWE3/MPLS MPLS-TP of TDM/ATM/Eth Bearing capacity of the business and supporting the synchronism that the network moves ahead simultaneously with Tai Wo IEEE1588v2 technology. On the network size at the same time, the quantity of base station of a city is far greater than the quantity of DSLAM, this has just determined to require higher to PTN on group’s Nets’ ability. ...

Fictitious LAN VLAN It is from the traditional LAN LAN Amplify coming out on the concept, the two are basically the same on function and operation. But VLAN divides the network into several parts on logic according to agreement, MAC address or port. In other words, a group of terminal devices of VLAN simulation, even if they have in different physical network one, not limited by physical position either. Function of VLAN be made in the the same VLAN, can communicate between the member, be isolated each other between the different the intersection of VLAN and user, if need communication and pass the route apparatus. VLAN makes network management simplify, can reduce the work station and move and change the necessary expenses, carry on logic and divide into groups conveniently, add, delete and revise user’s information and carry on the work of charging etc. through the network flow test tool. In addition VLAN can contain broadcasting the storm within the range of this VLAN, other VLAN users are not influenced, have saved the network bandwidth greatly, has improved the utilization ratio of the bandwidth. ...
