4.9.1 Networking Diagram
The convergence node needs to exchange Ethernet services with two access nodes at Layer 2.
LAN services of the two users (H and G) need to be isolated.
Service Requirement
In the network shown in
, the service requirements are as follows:
l
Three branches (G1, G2, and G3) of user G are located at NE1, NE2, and NE4 respectively.
The branches need to form a LAN and share a 10 Mbit/s bandwidth. G2 and G3 do not
need to communicate with each other.
l
Three branches (H1, H2, and H3) of user H are located at NE1, NE2, and NE4 respectively.
The branches need form a LAN and share a 20 Mbit/s bandwidth. H2 and H3 need to
communicate with each other.
l
The service of user G needs to be isolated from the service of user H.
l
The Ethernet equipment of user G and user H provides 100 Mbit/s Ethernet electrical
interfaces that work in auto-negotiation mode and do not support VLANs.
