Network Development (L3) Flashcards
(36 cards)
The ability to stimulate network performance relies on an ________ _________ of the net.
Accurate representation
Transport networks develop from…
1) scattered ports
2) penetration trunklines and gateways
3) interconnections
4) the development of high-priority trunklines and hierarchical systems
What’s new in the development of networks?
1) meltdown in global telecomm
2) increased awareness of vulnerability
3) possible flaws in hub networks
4) 4 more years of data and experience since our original draft
5) Upsurge in interest in various models of network evolution
Power Laws
Patent signatures of self-organization in complex systems
What are the 5 stages in the evolution of Internet Backbones?
1) System of nodes
2) priority nodes get the Infrastructure 1st
3) Infrastructures are linked to the world
4) little specialization (system has no tech upgrade)
5) system expands w/added nodes
Hubs determine the…(4)
1) structural stability
2) dynamic behavior
3) robustness
4) error & attack tolerance of real networks
Scale Free
The average number of links is not especially important
If we erroneously treat the net as the result of random growth, we ________ it vulnerability to deliberate attack.
Underestimate
We need to augment the network generation models with _______ ________; else, we have inappropriate benchmarks.
Spatial relationships
The “surprise” expressed by ________ about the __________ power law structure of networks seems to miss the basic _______ _________ principles that underlie interaction (hierarchy, integration)
Barabasi / non-random
Spatial organizational
Hubs stand as proof of the highly important organizing principles that govern _______ _________.
Network evolution
The simultaneous determination of _________ and _______ is a critical observation about the way a network system is made.
Trunk and gateway
The primary location of hubs and telecomm sends penetration lines into the _________.
Hinterland
The hub is a type of gateway used in ________ ________.
Economic development
As hubs and gateways prosper, _______ _______ are left behind.
Non-preferred
It is is rare to find a node with a large number of links in a _________ __________.
Random network
In _______ ________, most nodes have a few links.
Random networks
________ _________ distributions are characteristic of Internet backbones
Power law
Do a significant number of backbone nodes have a large number of links?
Yes
________ do not grow randomly.
Networks
Poisson model
Random connections
No nodes have a high degree
The mean or average is significant to that network
Easy to manipulate but not not representation of the real world
What are the 6 phases in the development of air transport?
Scattered airports
Penetration routes
More air route develop between cities - max degree of connection
More efficient spatial order through a fully connected network structure
A central hub facility develops
Process of de-hubbing
What 3 factors are used to analyze the results of the developmental air transport process?
Costs
Level of service
Market share
Complex Networks
Involve the study of the structure and evolution of interaction networks in which the formation of new linkages is a probabilistic function of the degree of the node.
