Differentiated Services

Basically, difference means to provide different QOS　for 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.

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

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

For enterprise network, Ethernet is a critical technology.

Token ring and ATM are gradually decreasing

Low cost , more versatile FE->GE->10GE->100GE

Smaller size, higher density, low power consumption

Trend I： bandwidth

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

Security problems we faced today

Security Laws: ISO17799, SOX, …Laws demand: Any information transmitted is traceable!!!

Crimes on IP network:Personal behavior ->organization activitiesNon-profits -> Profits

They may take anything away!!!
