-The attributes of the 'report' tag:
+A complete state report of the NIC router is structured the following way
+(example):
-'bytes' : Boolean : Whether to report sent bytes and received bytes
- per domain
-'stats' : Boolean : Whether to report statistics about session objects
-'quota' : Boolean : Whether to report quota and its utilization
-'config' : Boolean : Whether to report IPv4 interface and gateway per
- domain
-'config_triggers' : Boolean : Wether to force a report each time the IPv4
- config changes
-'interval_sec' : 1..3600 : Interval of sending reports in seconds

+The attributes of the tag correspond to the report content as
+described below:
+
+'bytes'
+
+A boolean value that controls whether the attributes 'rx_bytes' and 'tx_bytes'
+of the tag in the state report are generated. These attributes
+provide the number of bytes that were sent respectively recieved at all
+sessions/interfaces of that domain beginning with the creation of the domain.
+
+'stats'
+
+A boolean value that controls whether the subtags , ,
+, , and are generated in the tags
+ and . In the tag, these subtags provide further
+subtags , , , that provide the number of links
+of the protocol type that are currently in the denominated protocol state (a
+missing subtag denominates a number of 0).
+
+Furthermore, there are subtags that provide the number of links
+of the protocol type that were already dissolved by the router (i.e., they are
+already non-effective) but that weren't destructed so far. Thereby, the
+different tags group the links according to the reason why they
+have been dissolved ( thereby means that the protocol
+itself terminated the connection).
+
+The subtag can occur in <*-links> subtags in both the
+and the tag. It shows the number of links of the protocol type that
+once existed but were already destroyed. In case of the tag, the
+corresponding session/interface still exists at that domain. Once the
+session/interface gets destroyed or disconnected from the domain, the number is
+transferred to the subtag in the <*-links> subtag in the
+tag. I.e. the subtags in <*-links> subtags in the tag
+provide the number of destroyed links that can't be correlated anymore to any
+session/interface of the domain.
+
+The same applies for the subtags of <*-links> tags. They show the
+number of links that couldn't be established through the router because of the
+lack of a certain quota. Thereby, refers to a lack of RAM
+quota at the source session/interface of the link. The , at
+the other hand, refers to a lack of UDP/TCP-NAT-ports respectively
+ICMP-NAT-IDs at the target domain (see section [Configuring NAT]).
+
+The subtags , and list the number of still
+active ( subtag) and already destroyed ( subtag) objects
+for pending ARP requests respectively DHCP-address allocations at a
+session/interface when in an tag. When in a tag, they
+only list the number of already destroyed objects of these types that can't
+be correlated anymore to any session/interface of the domain.
+
+'quota'
+
+A boolean value that controls whether the subtags and of the
+ tag and the subtags and of the
+tag are generated.
+
+The former two show the capability quota respectively RAM quota of the router
+that isn't accounted to any of the sessions/interfaces connected to the router
+(i.e., the routers "own" quota). The 'quota' attribute denotes the total amount
+of quota available to the router, the 'used' attribute the part of the total
+amount of quota that is currently spent or in use, and the 'shared' attribute
+the part of the spent quota that, although it was spent for session/interface-
+specific things, can't be accounted to one session/interface technical reasons.
+
+The subtags and in the tag, however, show
+the capability quota respectively RAM quota accounted to that
+session/interface. The 'limit' and 'used' attributes are equal to the 'quota'
+and 'used' attributes of the and subtags of the tag. The
+'avail' attribute contains simply the 'limit' value minus the 'used' value.
+
+'config'
+
+A boolean value that controls whether the attributes 'ipv4' and 'gw' of the
+ tag and the subtag in the tag are generated. The
+attribute 'ipv4' contains the current IPv4 address of the router in this domain
+suffixed by the length of the subnet prefix in bits. The 'gw' attribute
+contains the IPv4 address of the gateway in this domain. Each subtag of a
+ tag shows the IPv4 address of a DNS server known to this domain. The
+ subtags have the same order that the addresses had when the router
+received them (i.e., the order of DHCP option 6 entries in the corresponding
+DHCP replies or the order of entries in the corresponding router
+configuration).
+
+'config_triggers'
+
+A boolean value that controls whether to enforce sending a report each time the
+state that is controlled through the 'config' attribute of the tag
+changes. I.e., whenever the IP configuration of any domain has changed.
+
+'link_state'
+
+A boolean value that controls whether the attribute 'link_state' of the
+ tag is generated. The 'link_state' attribute shows the current real
+link state of the session/interface. Note, that in case of a NIC session, this
+is not necessarily the same value as the one that the session client sees. For
+more information about that, refer to [Behavior regarding the NIC-session link
+state].
+
+'link_state_triggers'
+
+A boolean value that controls whether to enforce sending a report each time the
+state that is controlled through the 'link_state' attribute of the tag
+changes. I.e., whenever the real link state of any session/interface at the
+router has changed.
+
+'interval_sec'
+
+Defines the interval in seconds in which to unconditionally send a report.
+Must not be 0.
