【正文】 中國(guó)電信下一代承載網(wǎng)絡(luò) China tele Next Carrier Network(CN2） China Tele Corporation 韋樂平 Wei Leping Challenges Total voice traffic and revenue decreases by the end of 2022. The mobile phone and IP phone calls have cannibalized part of the voice traffic businesses Traditional munication work is unable to support China Tele’s strategy to bee a Integrated Information Service Provider. This is due to its lack of capability in offering valueadded service. High OPEX (Operating Expenses) is required for traditional hetergeneous/multiple works Existing ChinaNet is not a profit generating business Opportunities Acceleration of the Information and Communications Technology (ICT) adoption in government and enterprises would drives the demand for tele services Adoption of the SIPbased softswitch technology The impending releases of 3G license Rapid development of the broadband service Background Migration of voice service from PSTN to softswitchbased VoIP technology Preparation for 3Gbased mobile services Accelerate the development and application of the broadband services base on xDSL access technology Drive managed service and system integration service Built an Integated IP/MPLSbased multiservice platform — CN2 solutions Philosophy of Building CN2 CN2 strength work topology Scalable routing architecture Highest level of redundancy Highest level of security Different class service All services have edge functionality End to end control and managment Homogeneous Global Architecture Single Global ASN(AS4809) IP Layer Redundancy Drives Accountability ISIS level2only with subsecond convergence Diffservbased QOS enabled work MPLS and multicast enabled work MPLS FRR with sub50ms reroute Robust Architecture Allows for Unsurpassed Stability Offer Layer2/3 over IP or MPLS Leading SLAs via Zero Loss amp。 Speed of Light Delays 6PEbased IPV6 ready Offer Layer2/3 over IP or MPLS Leading SLAs via Zero Loss amp。 Speed of Light Delays End to end service provision and fault management CN2 Strength Simple Network Topology CN2 prises of two functional planes and four structural layers to offer a seamless connectivity for customers.
