3.1 Network Requirements
3.1.1 Requirement Analysis, Network Diagram and Configuration Plan
I. Requirement analysis
An ISP has four ASs: AS 100, AS 200, AS 300, and AS 400. AS 100 is the core layer. It
connects AS 200, AS 300, and AS 400 and forwards data between them. AS 200, AS
300, and AS 400 constitutes the distribution layer. They provide access services for
users. The specific requirements are as follows:
z Fast convergence is required for AS 200 and AS 400 because their networks are
quite large and complicated.
z The network of AS 300 is small and simple. The devices in the network supports
only RIP. Their performances are low and the capacities of routing tables are quite
limited.
z Access users in AS 200 require a very reliable network.
z Access users in AS 200, AS 300, and AS 400 are accessible to each other.
z S200_10 in AS 200 is connected with Layer 2 devices.
z S300_B in AS 300 is connected with Layer 2 devices.
z The data forwarding path needs to be controlled when users in AS 400 access AS
200 and AS 300.
z An AS 300 access user is interconnected with the ISP through a single link.
