3. Software

ASN-GW Controller

The ASN-_GW controller code is provided by NEC, and is based upon their commercial code.

Three components are provided by NEC, in binary only:

  • trapctrl - used for (snmp) alerts management (not currently used)
  • asnctrl - Daemon process that is in charge of R6 control functions. (well defined API)
  • epctrl - Daemon process that is in charge of R6 interface datapath. (sets up GRE tunnel from Mobile Station (MS) to data path module (e.g., CLICK modular router)

These must currently be loaded with various libraries, including the SF Tables library; some coulod be eliminated.

The asnctrl API can be found at:

These is an ASN_GW Controller configuration file; see below.

Data Path Module

For Case 1, the Data Path Module carries data between the NEC IDU and tbe GENI Access Network.

For Case 2, the Data Path Module carries data between the NEC IDU and tbe KVM VMs. Currently, the only supported Data Path Module is the Click Modular Router

Later, it is expected that an Open FLow Switch will be supported.

Click Modular Router

The current supported Data Path Module is the Click Modular Router, v1.6.

These is CLICK Modular Router configuration file; see below.

Sample Queries and corresponding outputs

1) To initialize the service.

  • Checks for the number of running VMs, populates MAC list and also assigns VLAN ids.
  • Is also supposed to send the VLAN information to the server on ASN-GW
    wget http://wm-asngw-02:5012/wimaxvm/initvms
    
    
    vm30 VLANid  7         mac address='52:52:52:52:52:52'/
    vm7 VLANid  2         mac address='52:54:00:1c:00:cb'/
    vm10 VLANid  6         mac address='54:52:00:2c:05:7a'/
    vm55 VLANid  3         mac address='01:23:45:67:89:ab'/
    vm57 VLANid  4         mac address='01:32:54:67:98:ba'/
    vm58 VLANid  5         mac address='01:65:23:67:98:ba'/
    vm5 VLANid  0         mac address='52:54:00:2a:85:b6'/
    vm6 VLANid  1         mac address='52:54:00:34:aa:a3'/
    

2) Start VM

  • Start vm, assign vlan tag and send info to server on ASNGW
  • Socket part is yet to be integrated
     http://wm-asngw-02:5012/wimaxvm/start/?vmname=vm30
    Domain vm30 started  with vlan tag 9
    

3) Stop VM

  • Similar to start VM, but does exactly the opposite
     http://wm-asngw-02:5012/wimaxvm/stop/?vmname=vm8
    Domain vm8 destroyed
    

4) Get statistics about a VM

  • Gets all relavent information for a particular VM name
    http://wm-asngw-02:5012/wimaxvm/vmstat/?vmname=vm8
    <domain type='kvm' id='40'>
      <name>vm30</name>

        <graphics type='vnc' port='5905' autoport='yes' listen='127.0.0.1'/>
      </devices>
    </domain>
    

5) Get VM list

  • Useful for an admin and gives a list of all VMs.
  • Format is vmname, Vlanid, vm-mac-addr.
     http://wm-asngw-02:5012/wimaxvm/vmlist
    
    vm30 VLANid  7         mac address='52:52:52:52:52:52'/
    vm7 VLANid  2         mac address='52:54:00:1c:00:cb'/
    vm10 VLANid  6         mac address='54:52:00:2c:05:7a'/
    vm55 VLANid  3         mac address='01:23:45:67:89:ab'/
    vm57 VLANid  4         mac address='01:32:54:67:98:ba'/
    vm58 VLANid  5         mac address='01:65:23:67:98:ba'/
    vm5 VLANid  0         mac address='52:54:00:2a:85:b6'/
    vm6 VLANid  1         mac address='52:54:00:34:aa:a3'/
