Detailed Answers| Already Graded A+||Newest Exam!!!
Why do active networks conflict with idea of E2E? -
Answer-They require customization at network nodes (not
simplicity at network core)
(7)
What were the two types of programming models in active
networking? How are thy different? - Answer-1. Capsule
model
- carries in band data packets
- most used in relation to active networking
- code distribution ACROSS networks
- data plane
2. Programmable router/switch model
- out of band mechanisms
- decision-making a job for the NETWORK OPERATOR
,2|Page
- Difference is where the code to execute at the nodes was
carried (7)
What are 4 tech developments that encouraged active
networking? - Answer-1. reduction in computation cost
(more processing can take place in the network)
2. advancement in programming languages
3. advancement in rapid code compilation and formal
methods
4. funding agencies promoted interoperability among
projects
- necessary because there were no short-term use cases
(7)
What are 4 problems that encouraged active networking? -
Answer-1. developing network services took a long time
,3|Page
2. third party interests to dynamically meeting needs of
app and network conditions
3. researches needed a network for large-scale
experiments
4. disadvantage of diverse models and vendors meant a
desire for unified control over middleboxes (7)
What are 3 contributions of SDN? - Answer-1.
programmable functions in network = lower barrier to
innovation
2. network virtualization and ability to demultiplex based
on packet headers
3. vision of unified architecture for middlebox orchestration
(7)
Which plane are active networks associated with? -
Answer-Data plane (7)
, 4|Page
What plane do programmable functions in active networks
focus on increasing programmability, and why? - Answer--
Data plane
- isolate experimental traffic from normal traffic (7)
What were some downfalls of active networking? -
Answer-- it was too ambitions
- didn't emphasize performance and security
- it didn't solve any short term problems
- end users need to be ale to write in java (7)
Did active network do anything for performance? Security?
- Answer-No (7)
What challenge did control and data plane separation
tackle? - Answer-Challenging how existing routers and
switches tightly integrated the data and control plane (7)
What were 4 tech developments that paved the way for
control and data plane separation? - Answer-1. packet
