Agenda
� Why Robust Network for ITS
� Three Key Elements• Versatility
• Reliability
• Scalability
� Summary
2
Why Robust Network for ITS
� Communication infrastructure is a pre-requsite
for ITS
� Requirements• Integration of existing systems
• Mission critical ITS applications
• Deployment and maintenance costs
3
1st Key Element: Versatility
� Integration of existing systems• Ethernet backbone
• Existing legacy serial devices
• xDSL connections
• Wi-Fi/cellular applications
4
Benefits of an ETHERNET Backbone
�Cost-effective
Low Total Cost of Ownership
� Interoperability
Open Standard
�Expandability
Add Network Segments in the
Future
�Future-proof

2nd Key Element: Reliability
� Severe and harsh outdoor conditions���� Industrial Ethernet
� Cyber security
� Advanced network redundancy���� Redundancy protocols
10
Building Reliable Networks in ITS
� Challenge• High Availability
• High Flexibility of Topology
• Lower Total Cost Ownership of Network Installation
� Solution• Turbo Ring
• Turbo Chain

Redundant Technology
Type Mesh STP RSTP
Feature• Every node connect to
each other
• Defined in IEEE 802.1D• Loop-free tree shape
topology
• Defined in IEEE 802.1w• Loop-free tree shape
topology
Pros• Highly reliable• Self-repairable
• Auto form backup link to prevent looping
• Auto re-arrange connection when network failure
• Same features as STP• Faster recovery time:
1 sec
Cons• Too costly for large
network deployment• Recovery time: 15 sec
• 1 sec recovery time is too long for industrial application

Redundant Technology
Type Ring
Feature• Every node connect as a ring• Proprietary technology
Pros• Lower deployment cost• Auto re-arrange connection when link down• Fastest recovery time (20ms)
Cons • Hard to deploy in distributed and complex network
Typical Redundancy Technology
Extremely Flexible: Any Topology
Fast Recovery< 20 ms
Saves InstallationCost & Time
Save Extra Fiber
Easy Extension
(Can Link to STP, RSTP, Turbo Ring, Turbo Chain)
Turbo Chain:Beyond Redundant Rings

3rd Key Element: Scalability
� Convergence of ITS networks
� High bandwidth and Industrial core layer
switches
18
Converged and Edge-to-Core ITS Networks
19
Requirements for Industrial Core Layer Ethernet Switch for ITS
FAN less, 0 to 60°C
Up to 4-10GbE ports

Hot Swap* design
� Industrial Grade
� High Performance
� Non-stop Operation
20
Summary
� Network components should providecapabilities to integrate diverse connectivities and existing systems in ITS
� Industrial grade, ruggedized, and robustproducts should be used as most of ITS applications are safety and mission criticaland operate in harsh outdoor environment
� ITS Networks should be scalable for furtherexpansion such as video surveillance applications
