Introduction
Introduce the context, citing TridentCom'08. Not too long (a couple of paragraph should be ok) [Miguel]
Reference Architecture
The reference scenario architecture is composed of several domains. Each domain consists of an core netowrk (CN) and an arbitrary number of access networks (ANs). The IMS lays within the CN, consisting of a set of CSCFs proxies (our model considers one of each type: P-CSCF, S-CSCF and I-CSCF). Each AN is connected to its corresponding CN through an Access Router (AR).
The different domain CNs are connected through an interconnection point (IX), also known as inter-PLMS (Public Land Mobile Network) backbone. The IX also interconnect a segment of auxiliary network elements (such as a DNS server).
The scenario considers two kinds of attachemnt point for external equipment: access networks (for UEs) and IMS cores (for core entities, such as the SIP Application Server shown as example in the figure below).
The following script [TODO] allows VNUML multi-domain specifications automatically. Some observations follow:
- The first parameter is the number of domains (D) and the second one the number of access network per domain (N).
- The 'external' attribute is not added in neither acc*_* nor core* <net>s, due to it is depend of the host physical interface (e.g., eth0, eth1, etc.) and the particular VLAN ID being used. Therefore, user needs to edit the resulting XML properly.
- An auxiliary segment with a DNS server is added
- IPv6 addresses are automatically assigned to each element
- The script only generates homogeneous specifications, i.e. the same number of AN for each domain, although the resulting XML can be easily prune to fit user needs.

Interdomain Mobility Scenario
The inter-domain mobility mobility can be download here: sae-inter.xml (TODO)
[Missing Figure]
The scenario is composed of five domains (it can be obtained after pruning the scenario generated by the script with D=5 and N=1), which may play the following roles:
- Domain 1 (one AN): Terminating Visiting
- Domain 2 (one AN): Originating Final Visiting
- Domain 3 (one AN): Originating Initial Visiting
- Domain 4 (no AN): Originating Home
- Domain 5 (no AN): Terminating Home
Note that acc1_1, acc2_1 and acc3_1 <net>s use the 'external' attribute in order to allow the interconnection of external UE equipment. However, note that the values considered in the example (eth0.121, eth0.122 and eth0.123) have to be changed to match the proper ones in your emulation environment.
