4. 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

Ethernet and MPLS packet technologies are extended with a Transport Profile (TP)
MPLS is extended with a single transport profile, Ethernet is extended with two transport profiles (with different tunnel layer technologies: VLAN and MAC)
The layer stacks for those three PTN technologies are very similar and management of these PTN variations can be unified under a single PTN Network Manager

Interoperability for those services is as such guaranteed; main difference is the tag/label used to identify each service VLAN

42. Interoperability for EVPL services
under discussion
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”)
ETH/MPLS PW InterWorking function provides such interworking
Similar OAM PDU formats and similar client encapsulations make interworking trivial
