IP/Ethernet Options<br />
� IP/Ethernet scenarios <strong>in</strong>clude:<br />
– In R5 3G, LTE and mobile WiMAX environments, the RAN<br />
equipment <strong>in</strong>terfaces use the IP TNL – either at the Iub<br />
<strong>in</strong>ter-face (for 3G) or on R7/R8 for LTE or mobile WIMAX.<br />
– <strong>Mobile</strong> traffic over IP TNL can be transported either via<br />
Ethernet pseudowires or regular IP/<strong>MPLS</strong> TE tunnels over<br />
MMBI’s mobile backhaul network.<br />
– IP term<strong>in</strong>ation can take place either at the edge node, the<br />
access node, the access gateway or directly at the RAN<br />
equipment.<br />
� Various deployment scenarios arise depend<strong>in</strong>g on<br />
the location (and the extent) <strong>of</strong> <strong>MPLS</strong> technology <strong>in</strong><br />
the mobile backhaul network and whether it<br />
comprises both the access and aggregation sections<br />
<strong>of</strong> the network or just the aggregation section.
