There can be multiple hos= ts connected to the MANET radios at each MANET platform (vehicle) - either = directly via ethernet or via a router connected to the MANET radio. Two of the desired services of this MANET network are 1. for applications in a host at one MANET platform to send packets to h= osts at platforms of MANET radios that are one-RF-hop away from the source'= s MANET radio (called "One-RF-hop-cast") and 2. for applications in a host at one MANET platform to send packets to h= osts at platforms of all the other MANET radios. (called "All-RF-cast") We can't address these two services using IP link-local broadcast (255.255.= 255.255) or directed subnet broadcast because the hosts could be in differe= nt IP subnets at the different MANET platforms. Thus, we are planning to define two IP multicast addresses to indicate thes= e two services. One multicast to go to hosts connected to radios one-RF ho= p away via the MANET network and one multicast address to go to all hosts c= onnected to the MANET network. We can have two choices for defining those multicast addresses 1. define two addresses from the Administratively Scoped Multicast Space= defined in RFCs 2365 and 5771 or 2. request two global multicast addresses from IANA (probably from Ad H= oc Block 1 defined in RFC 5771). Questions 1. are there any other MANET networks/protocols today that do something = like this?

I am working on a multihop MANET network protocol de= sign where the MANET radios can be one or more RF hops from each other.&nbs= p; There can be multiple hosts connected to the MANET radios at each MANET = platform (vehicle) – either directly via ethernet or via a router connected to the MANET radio.  

 

Two of the desired services of this MANET network ar= e

  1. for applications in a host at one MANET platform to send packets to h= osts at platforms of MANET radios that are one-RF-hop away from the source&= #8217;s MANET radio (called “One-RF-hop-cast”) and
  2. for applications in a host at one MANET platform = to send packets to hosts at platforms of all the other MANET radios. (calle= d “All-RF-cast”)

 

We can’t address these two services using IP l= ink-local broadcast (255.255.255.255) or directed subnet broadcast because = the hosts could be in different IP subnets at the different MANET platforms= .

 

Thus, we are planning to define two IP multicast add= resses to indicate these two services.  One multicast to go to hosts c= onnected to radios one-RF hop away via the MANET network and one multicast = address to go to all hosts connected to the MANET network.

 

We can have two choices for defining those multicast= addresses

  1. define two addresses from the Administratively Scoped Multicast Space= defined in RFCs 2365 and 5771 or
  2. request two global m= ulticast addresses from IANA  (probably from Ad Hoc Block 1 defined in= RFC 5771).

 

Questions

  1. are there any other MANET networks/protocols today that do something = like this?  If yes, how do they indicate the desire for these two serv= ices?
  2. are these two services general enough that they = should become a global service that is available in other MANET networks/pr= otocols than the one I am working on?
