[Vini-dev] Help for using MyVINI!

[liyong 00164768]

Hi all:
    I am a new user for VINI, with my colleagues, we have
built a private VINI testbed while  we do not even have
the experience of using the public planetlab, thus we have
many problems when using our private VINI testbed.  Some
problems encountered us are as follewed:
    1. How do I give a limit of bandwidth to a slice/sliver?
    2. How can I configure a vserver in a node into a simple router?
    3. What do the tags mean both for a slice and a node? If
I want to modified the attribute of vini_topo, can I achieve this just by setting a value of "none","iias" to the tag of vini_topo? and can I set a tag of net_max_rate to a constant value to limit the bandwidth of a vserver in a slice?
    Any reply will be welcome!
    Thanks very much!
