PACKET TRANSPORT NETWORKS: WHY?

Consolidating service delivery infrastructure� Legacy (circuit-based) services (typically 20%-30% of traffic)

� Rapidly growing packet-based services (70%-80% of traffic)

The role of OTN in the network� Improving wavelength reach and OAM� Migrating SONET/SDH links onto 100G wavelengths


� Migrating SONET/SDH links onto 100G wavelengths

� Private Line services

� Multiplexing L1 and L3 networks over 100G wavelengths

OTN is not good at� Handling dynamic bursty variable-speed traffic flows

� Dynamically aggregating variable traffic patterns

� Providing L3 protection

� IP traffic is most efficiently handled by packet switches

� Dynamic bandwidth allocation� Statistical multiplexing

PACKET TRANSPORT NETWORKS: HOW?

PACKET TRANSPORT AND ROUTER BYPASS

Router Bypass?

Network planning technology where optical connectivity is topologically richer than IP/MPLS node map. IP/MPLS nodes are by-passed by

� Select wavelengths inside the transport optical element (optical bypass)� OTN circuits (opaque bypass, OTN bypass)


Often popularized as a tool to reduce network CAPEX and energy footprint, through the reduction of transit traffic (and hence ports) on IP/MPLS nodes.

In essence, the promise is that bypass shifts the CAPEX budget out of (expensive) IP/MPLS equipment towards (lower cost) optical gear.

IP NETWORKS MYTHS

IP/MPLS (packet) nodes in the core are routing pack etsPacket route is typically known at the core ingress point. Most core nodes are NOT routing – they are intelligent statistical multiplexers filling the core bandwidth at packet-level resolution

Transit traffic can be efficiently “removed” from nod esReal traffic in networks follows complex distribution patterns and static de-multiplexing wastes bandwidth. Traffic composition is different in every node

Bypass saves IP/MPLS portsIn some cases it does. However, the savings are mostly nullified by adding OTN switches and ports


In some cases it does. However, the savings are mostly nullified by adding OTN switches and ports to compensate.

“Hollow Core” network can scale to complex topologiesThis requires a very high degree of meshing (worst case N*(N-1)/2). All complexity moves to the edge and aggregation network, again negating possible cost savings. Router-OTN hand-off is complex and expensive (traffic must be shaped into each virtual interface requiring hierarchical QoS)

OTN switches can do the same job as IP/MPLS nodesThis requires adding significant capabilities (MPLS, OSPF, LDP, RSVP, TE FRR, …). More intelligence means more complexity and costs. In essence you are re-inventing the router.
