A7 Network design Solution A3

Aggregate traffic (Figure A.4) requires minimal routes and needs a maximum of one router hop to reach all destinations. Consolidation of Internet traffic enables effective use of corporate firewall at the main office.

Using requirement that link usage not exceed 50% of available bandwidth allows us to arrive at the circuit quantities shown.

Aggregate traffic

Note: Branch B is best served by 2 m data stream rather than 14, 64 k circuits. Similarly on costings given it is probably more cost effective to provide 2 m to Internet, rather than 5 x 64 k (Figure A.5).
