|What Are the Uses of AVES?
The primary use of AVES is to provide bi-directional connectivity to
hosts without IP addresses. For example, if you share a DSL or cable
modem Internet connection among several hosts in the home, then AVES
can restore bi-directional connectivity to these hosts so that they
can be reached from outside the home network. With AVES, many
applications become possible once again, here are just some common
- Get a fixed host name for your NAT gateway even if you only get a
dynamic IP address from your ISP.
- Run VNC (Virtual Network Computing) servers on home
computers and interact remotely with your home computers.
- Bring up X windows applications on any home computers when accessing
outside servers (without messy ssh X forwarding).
- Run peer-to-peer applications that use host names to address peers.
- Run web servers on any home computers.
- Run network file servers (e.g. NFS) on any home computers.
- Remote login to any home computers using telnet, ssh, etc.
- Transfer files from any home computers using ftp, scp, etc.
- And many other possibilities
In addition, since AVES generally provides a layer of indirection
through the AVES waypoints, there are other situations where AVES can
be beneficial even when there is not a lack of IP addresses. For
- When the true location of a host must be hidden from its
communication peers. This may be desirable for security or privacy
reasons. Using AVES, the true location of a host is hidden by the
- When an indirection is needed to achieve connectivity. This may
sound strange, but it turns out that some DSL or cable modem service
providers do not provide connectivity between their own customers. For
example, one may not be able to connect to his neighbor's computer if
both neighbors are customers of the same DSL provider. The only way to
achieve connectivity in this case is by an indirection through a
3rd-party relay. The AVES waypoints can serve this purpose.
Note that these alternate uses of AVES are not yet efficiently
supported by our current protocols and software
implementations. Better support for these features may be added in
