Public IP Services;
Not The Internet
• The road to profits is in Public IP Services
Networks
– A best-effort Internet doesn’t deliver service provider profits
– Profits continue in classic data networks because they
deliver quality service
• But…the Internet delivered some great
successes
– Infrastructure for common communications: The TCP/IP
protocol
– Infrastructure for applications: Browsers, Streaming Media
Formats, Email, Messaging, Directories
• Today, customers require the service richness of the Internet
with the service quality of the classic data networks

IP Is the New Public UNI
(Network Connection)
•
Public IP Networks Require
• Routing functions on the edge
– Consistent interface to subscriber applications
• Application-Aware Dynamic Service Delivery
– End-End Across The Network
• Network Changes Behavior As Necessary
•
Public IP Networks Must Provide
• Application-aware priority for IP flows
• Application specific behavior for different IP Flows
– Deliver bandwidth, and access privileges as required
• Per application
• Dynamic signaling to support application
requirements
– Deliver services where and when they are needed
• By requesting them from smart network elements
•
Public IP Networks Cannot Use a Hop-by-Hop Internet
Architecture
• Routers alone won’t support what needs to be done

Deterministic Service
Behavior
• Service-specific functions in virtual
routers

–
Traffic classification
• Voice, video, data
Marking, shaping, policing
• Priority queuing of IP application traffic
– Voice first, then file transfer data packets
Mapping IP application traffic to MPLS paths
• To ensure service quality
• Pre-engineered traffic paths in core
–

Supports MPLS paths in:
• Frame based networks (core router-based networks)
• ATM multi-service networks
– Provides: bandwidth guarantees, latency
commitments
– Provides: QoS

Network Architecture for
Public IP Services
Key Architecture Elements
• Service Intelligence to build end-to-end services
– Virtual Routing
– Intelligent Agents
– Service Creation Model
• MPLS to create dynamic connections in and between layers
in the network
• Unified network management for provisioning,
monitoring, fault recovery
• Professional services for full public network design and
lifecycle management expertise

• MPLS is an integral architecture element for
communication in and between the network layers
– Multi-Protocol Label Switching (MPLS) is not only used for
traffic engineering in IP Networks
• A Fundamental framework for Service Intelligence in
Public IP Services networks
• Benefit: Creation of highly customized services
based on subscriber, application, and network
requirements

MPLS for Dynamic Connections:
within the IP & ATM Transport Layers
• Multiservice ATM Core

Frame Relay, DSL, ATM
Access and Multiservice

MPLS for Dynamic Connections:
Between Layer 1 and Layer 2
The service intelligent
network requests bandwidth
and transport from the optical
core via dynamic MPLS signal
requests
IP/ATM
Core
Benefits:
•Sub-second restoration
in case of failure
•Automatic addition of resources in
response to demand
•Layer 1 & Layer 2 are active
participants in service delivery

Unified Network Management
For IP Services
• Single service console for IP Services
–
Creation and management of all IP Service elements: Customer Located
Equipment (CLE), Service Switch, Core
–
Service creation built within virtual routers
–
Policy driven network behavior not “port-by-port” configuration using
network directories– like the voice network.
• Flow-through integration with Layer 2 infrastructure
–
–
Automatic connections between devices
End-to-end within layer-two framework
• Layer-one integration with dynamic signaling:
–
On demand bandwidth creation driven by Service Intelligence through
ODSI/OIF Optical Interface
Benefit: scalable, single seat management with end-to
end provisioning, monitoring, fault isolation

Intelligent IP Service Management
• Provisioning
–
–
–
–
Unified – supports all network elements actively
enforcing Service Attributes
Scaleable – Virtually centralized with distributed
content
Integrated - Built on top of a single platform
Flexible – GUI or API driven
• Surveillance/Assurance
–
–
Common Fault and Performance architecture
SLA Assurance w/detailed analysis
• Capacity planning

Radically Different Approach
• Policy driven network behavior
– Not “port-by-port” configuration
• Configure the network services, not the devices
• Let the devices grab configuration elements and change
behavior as users of a service arrive at a port
• IP Framework for Services
– Service creation built within virtual routers
• On edge of service provider network
• Driven by central database servers

• IP Data Services
–

• Service elements: predictable bandwidth, security,
connection oriented IP
– IP “conference calls”
– Managed bandwidth services per application
– Predictable “SLA’s” for customer and carrier

Policy Driven Service Creation
• As with voice:
– Specific subscriber profiles drive network element
behavior
• Same with Data:
– Network elements interact with provisioning servers
– Service Provider defines services
– Active network “reacts” to policies
• Sets-up network resources on behalf of users
• Uses MPLS, other technologies to signal for enforcement
of service attributes

• Users edit web pages that update LDAP service profiles
• Active network elements get “change notice”
