#****h* imunes/linkcfg.tcl
# NAME
# linkcfg.tcl -- file used for manipultaion with links in IMUNES
# FUNCTION
# This module is used to define all the actions used for configuring
# links in IMUNES.
#
# NOTES
#
# linkPeers { link_id }
# Returns node_ids of link endpoints
#
# linkByPeers { node1_id node2_id }
# Returns link_id whose peers are node1 and node2
#
# removeLink { link_id }
# Removes the link and related entries in peering node's configs
#
# getLinkBandwidth { link_id }
# ... in bits per second
#
# getLinkBandwidthString { link_id }
# ... as string
#
# getLinkDelay { link_id }
# ... in microseconds

# getLinkDelayString { link_id }
# ... as sting
#
# setLinkBandwidth { link_id bandwidth }
# ... in bits per second
#
# setLinkDelay { link_id delay }
# ... in microseconds
#
# All of the above functions are independent to any Tk objects. This means
# they can be used for implementing tasks external to GUI, yet inside the
# GUI any updating of related Tk objects (such as text labels etc.) will
# have to be implemented by additional Tk code.
