Core Trends


Traditional Core Architectures (Full / Thin)

Core routers forward on IP and / or MPLS

Some core routers support millions of routes (5M+)

Full and Thin versions vary by service richness, scale

Inter-router links are provisioned over P2P DWDM

Packet / optical administrative domains are isolated

Little or no packet / optical topological coordination other than IPoDWDM / G.709

Packet

Optical


Hollow Core Architectures

OTN switches replace the packet core

OTN circuits form a mesh between Edge, Peering nodes

Edge, Peering nodes must absorb high adjacency loads

Packet Stat-Mux efficiencies are no longer possible

Packet / optical administrative domains remain isolated

No packet / optical topological coordination (Ethernet-only)

Packet

Optical


Lean Core Architectures (Generalized)

Label-Switched Routers (LSRs) replace core IP/MPLS routers

Forwarding is via MPLS only

Nominally less costly due to less memory, simplified NPEs

Edge / Peering routers must encapsulate all core traffic

Migrations can be complex and disruptive to services

Costs are potentially just shifted to the Edge – not eliminated

Cost and scale are optimized without ‘Inner-Core’ disruptions

No increase in non-revenue interfaces

Integrated IPoDWDM provides direct packet optical integration

The Interaction at WorkPath Setup

• Matching /Disjoint / SRLG / Latency Circuit• Today:• L3 requests circuit of L0 team• Ingress and Egress may be different• L0 verifies available path• L0 verifies performance and resources• L0 / L3 Coordinate Circuit Turn up

• nLight:• Client Signals circuit request with Disjoint path as other circuit ID• L0 signals wavelength or path error message• Consider SRLG, LFA, Optical Impairment (WSON)

The InteractionProtection Event

• Restoration – L3 Protect -> L0 Restores• Today:• Protection is provided via L0 Team

• 1+1, Fiber protection, etc…• Does not efficiently utilize available BW• Increases Cost per Bit

• Protection is provided via L3 team• Decrease Interface Utilization • Does not efficiently Utilize BW• Increase Cost per Bit

• nLight:• L3 detects Circuit degradation and initiates Proactive Protection• L0 Restores capacity back to network and signals existing router port to change if needed• Increased Link-loads supported due to re-signaling capability

CRS-3 Update


• Back to Back MC allows you to remove fabric chassis using existing CRS-3 MC fabric cards

• Enables 32 slot CRS 2+0 MC which is functionally equivalent to 2+1 MC

• Greatly reduces CAPEX and OPEX costs of Multi-Chassis

• Lower CAPEX – No FCC or S2 fabric cards needed

• Removal of FCC – 2/3 rack space for same capacity

• Lower OPEX - 23% Reduction in power usage

• Chassis can be migrated to a larger MC system using same fabric cards

• Use same fabric cards (S13) as LCC

• Add FCC and existing fabric cards can be used to create a larger MC system

On-board analytics engines One-PK: Custom application building capability to

dynamically control and configure the router; and leverage the advanced routing infrastructure

Carrier Grade Services EngineEnabling IPv6 Transition and SP Services


Centralized Architecture: traffic is passed through a "cleaning center" via a proxy, which separates "bad" traffic (DDoS and also other common internet attacks) and only sends good traffic beyond to the server

Elements: a) Netflow on routing infrastructure, Arbor PeakFlow SP for: b) detection (SP Collector) and c) mitigation (SP TMS)

Distributed Architecture: integrated SP TMS on the CRS+CGSE. Distributed architecture to replace a full bank of TMS servers

Benefit: complete integration with Arbor Peakflow SP. Seamless integration with routing infrastructure for better TCO, avoid tunneling attack traffic to scrubbing center
