  1. Evolution of IP Network RACS 100G BROADBAND DIFFERENCE Evolution of IP Network RELIABILITY ETHERNET Security Carrier Ethernet

  2. Evolution of IP Network RACS Bandwidth Broadband Difference Evolution of IP Network Reliability Ethernet Security Carrier Ethernet

  3. need Applications Bandwidth New Evolution of Bandwidth 100G 2005 40G Transmission 2002 Switch 10G • DWDM 160×40G • 40G interface • 10Tbs switch • cluster chip • 65nm -> 45nm

  4. Basically, difference means to provide different QOSfor different customers and different services User QoS Highly perceptional, hard to quantify. Application QoS Applications change so do requirements. Network QoS Easy to quantify, well defined. All other QoS can be expressed in these terms. Metrics well defined. Availability Delay Delay Variation Throughput (Bandwidth) Packet Loss Rate. Differentiated Services ＃＠~lo Driver of QoS Technology Hello B A Internet QoS Service Drive Operation Drive • VoIP • IPTV/VoD • Triple-Play • …… • Multi-Service in one netwok • CapEX • OpEX • …… Precise operation mode Extensive operation mode characteristic services Bandwidth QoS Technology Differentiated service Bandwidth Basic service Bandwidth Capability bearing network Capability of service

  5. Evolution of IP QoS Technology Best Effort • RED, WRED, CAR, No QoS guarantee Diff-Serv • DS Byte, PQ, WFQ, LLQ …,Scalable, incremental implementation. • RSVP, Bandwidth Allocation, Not Scalable, consistency issues. Int-Serv • E-LSP & L-LSP, Constrain Based Routing, • Dynamic Network Resource Control, Bandwith Reallocte • On Demond. MPLS Dynamic QoS IP Qos technology

  6. PORTAL Latest development——RACS feature of Metro Broadband Access Network Services User’s website Application System Service management Policy Management Layer Difference Control Platform IPTV,IDC Content Delivery Network Network Layer CN2 Backbone of MAN ChinaNet Family network Access network L2 Integration Network Service edge of MAN

  7. Service Innovation V35、ISDN Application Ethernet home Net ar VIP Ether IP network 企业网以太化 • For enterprise network, Ethernet is a critical technology. • Token ring and ATM are gradually decreasing Ethernet Card Phone Token ring ATM、FR IAD/HomeBox VPI/VCI network Camera E1 Terminal 以太化 • Broadband takes the place of narrowband • Instead of ATM, Ethernet to the desktop has become the future trend. • Private line users move forward to Ethernet • IAD/home box has been extensively used 城域网以太化 • DSLAM and its aggregation technologies apply Ethernet. • LAN access is widely used • The equipment of Metro Backbone network interconnect with each other over Ethernet • Metro Ethernet is based upon 1 million users • TDM over Ethernet SOHO

  8. Gaming, Business Backup, ERP Voice/Video Telephony HDTV TVoD, VoD Internet Wireless Backhaul Voice gateway Carrier Ethernet Network Broadband mobile data/video Business Broadband E-Line and E-LAN service Residential Triple-Play Small/Medium Business Development of Ethernet technology FTTx and DSLAM , Cable Modem Carried ether Second Having features of telecommunication network First cost-effective bandwidth ？？？ OK FE->GE->10GE ->100GE Secure, reliable, scalable, easy to manage Trend I：bandwidth • Low cost , more versatile FE->GE->10GE->100GE • Smaller size, higher density, low power consumption Trend II：carried • Required driving forces：Internet, NGN and IPTV are carried uniformly. • Related Technologies：VPLS TE，PBB-TE，Ethernet Ring，H-QoS，Ethernet OAM，PWE3，and Synchronized Ethernet • Developing Trend: carrier-class Ethernet plays an important role in the core aggregation layer of PSTN

  9. Security problems we faced today Crimes on IP network: Personal behavior ->organization activities Non-profits -> Profits They may take anything away!!! Security Laws: ISO17799, SOX, … Laws demand: Any information transmitted is traceable!!!

  10. Evolution of Unified Network Security Internal Network Security External Network Security Time Storage Security Terminal Security Server Security Active pre-defense Location Event Processing Physical security ：environment identification、resource management , redundancy Event Tracking Network layer security：firewall, IDS/IPS Technical layer Application layer security：application filtering , P2P filtering, ERP gateway, database Content layer security：E-mail filtering, document security, web filtering content

  11. The future of network security There are so many security problems in our life. In the digital world, he who know nothing about network security lives a happy life. It’s our responsibility to protect their happiness. One security worker Person of the year 2006 network security
