Services and Network Evolution


Services and Networks

Three main network types “Layer 1” optical transport network “Layer 2” packet transport network “Layer 3” public services network

Each network provides “Services” “Layer 1” high rate bitstream and framestream services,

long holding times “Layer 2” medium rate packet/frame and bitstream services,

long holding times “Layer 3” low rate packet and bitstream services,

short holding times (for voice, data, video)

Each network must provide world wide connectivity Scalable network designs by means of aggregation and partitioning

Services Evolution

In 20th century (’80s/’90s) main Services were Layer 3: voice and fax Layer 1: E1/T1

In next decade the main Services will be Layer 3: voice, data, video Layer 2: Ethernet VLAN, E1/T1 Layer 1: 1GE

Significant increase of average/peak service rates in all “Layers”

Network Evolution

In 20th century (’80s/’90s) main networks were Layer 3: PSTN, 2G Layer 1: SDH (synchronous digital hierarchy) Fibers carry Mbit/s and Gbit/s

In next decade the main networks will be Layer 3: NGN, 4G Layer 2: PTN (packet transport network, ethernet vlan & mpls-tp based) Layer 1: OTN (optical transport network) Fibers will carry Gbit/s and Tbit/s

Two out of three PTN technologies deploy a service VLAN to support LINE and TREE services, one technology deploys MS-PW (optionally this may also be a service VLAN)Interoperability for those services requires service VLAN to MS-PW interworking (as per clause 5.5/G.805 “layer network interworking”)
