| 2、Financial institutions |
Features:
High requirement for security, stability and maintenance of network as capital trading is involved.
High requirement for real-time property as online trading and payment data flow is large in amount.
High requirement for convenient access mode as having lots of branches and subsidiaries.
QoS guarantee
Solutions:
Generally adopt ATM network to guarantee the business quality and provide QoS level.
Headquarter takes double link backup pattern to ensure the reliability of the core node.
Branches apply multi access modes including EDSL, FR and FE to realize interconnection. |

| 3、Small and medium-sized enterprises |
Features:
No big network construction scale;
Certain requirement for the speed, reliability and transmission quality of dedicated line;
Sensitivity to price
Solutions:
Adopt SDH interconnection mode between a headquarter and its subsidiary with optical transmission platform to ensure the transmission quality;
Use SDH self-healing ring to guarantee the reliability of transmission;
Take bundling link technology to make dedicated line speed up to Nx2M |

| 4、New business mode |
MPLS VPN
MPLS (Multi-Protocol Label Switch) is a new-generation IP backbone exchange standard proposed by IETF and is a kind of integrated IP Over ATM technology. It is an integration of IP routing technological flexibility with ATM exchange technological simplicity and provides label switch service similar to virtual circuit by introducing the connection-oriented properties of MPLS to connectionless IP network.
Typical case:
A large transnational software company has developed 5 subsidiaries in China so far and to better meet the demand of further development, it intends to realize interconnection between its subsidiaries through MPLS/VPN networking mode.
Solutions:
The network center (Shanghai) applies optical fiber + photoelectric converter to realize MPLS network access.
The total rate at the port of access point is 10M and user's router interface is RJ45 or optical interface directly provided.
For important branches and subsidiaries, optical access mode is adopted with 1M or 2M rate. |
