Twin Sons of Different Mothers:
Latency and Bandwidth
Chris Crosby, CEO, Compass Datacenters
Related, But Not the Same
The Impact of Latency
• Study by Akamai
• 1 second delay in page load speed
• 16% drop in customer satisfaction
• Rich packet applications are more
demanding
• Ex: Netflix
• IoT
• “Instantaneous” packet processing
• Critical for many applications
• Ex: Real time inventory
• Data reads and writes
• No such thing as a multi-availability zone public
cloud database
3
The Latency Factors
4
• Distance and contention
Latency: Factors
• Operational requirements
• Ex: Hypervisors add overhead to transmission speed
• Contention for bandwidth (Public clouds)
5
Solving the Latency Issue
• For now it’s geographical
• Moving data as close to the end user as
possible
• Edge data centers
• Emerging
• Micro datacenters
• Cisco FOG architecture
• Any device can be a data collection point
• Must have computing, storage and network
connectivity
6
Insufficient Bandwidth
• IDC
• “50% of existing networks will be bandwidth constrained as a result
of IoT”
7
The Traditional Network
• Access via public means
• Internet
• Too many “chokepoints”
8
Source: Forrester
An Alternative Approach
• Presented to a Compass customer
• Direct Peering
• Direct cloud connectivity
• Eliminate public internet

Eliminate the Internal Bottlenecks
• Network only as fast as slowest component
• Backplane contention
• Considerations:
• Top of rack switching
• Faster switches
• 10, 25, 40, 50, 100GB

Summary
11
• Speed of delivery will only continue to grow
• Lower latency
• Higher bandwidth speeds
• The important question:
• Can the network support what you want to do?
• Must eliminate contention/chokepoints
• Internal and external
• Failure to do so will result in:
• Ineffective operation
• Customer dissatisfaction
• Must find partners agile enough to quickly adapt
