Providing Services in Node Network Modal

      Disclosed is a method in which nodes are dynamically provided
network management services by computer network resources.

      Node network modal in which this method can be practiced, nodes
are classified as server node and served node.  Served node can
request network management services to a server node.  For any given
service, the same node may both act as a server node and as a served
node relative to the the different nodes with which it is paired.
Thus, a given node B provides a certain service to node A while
concurrently receiving services from node C.  In this node network
modal, multiple server nodes can provide network management services
to a served node.  Each node has a served nodes table and server
nodes table listing its served and server nodes, respectively.  Each
node also includes origin-independent relationship table and origin
dependent relationship table.  Origin-independent relationship table
of a node lists mapping from its own active served nodes names to its
own active server nodes name.  Origin-dependent relationship table of
a node lists mapping of active service request origin nodes name to
its own active server node name.  A node uses these two tables to
dynamically assign active server nodes.  These tables help
dynamically
distribute net work management service tasks across many nodes.

      Node which has no special performance requirement for network
management services, uses origin independent relationship table.
When such kind of node need a server node for network management
services and is itself also a server node for other nodes, it
generates a loop detection message including its name and forward it
to all active server nodes.  The message is passed from served to
server node using information of origin independent relationship
table.  Each nodes inspect the message.  If it does not find its own
name, it appends its name to the message and passes it to its server
node.  The node chooses one of the server node which did not return
loop detection message as its server and update its own and its
selected active server node's origin independent relationship table.

      The node which has some special performance requirements for
network management service updates origin dependent relationship
table across the nodes chain leading to service originating node to
establish server/served relationship.  Service originator node is the
node which itself is not a served node for any other server.  Figs.

explain this method.  Flow charts of Figs. 2 and 3 explain process
box
(8) and (9) in details, respectively.  This method uses loop
detection
message, return message and table update message.

      Loop detection message is the message generated by a node when
it needs a server node for some network management service (1).  This
message is broadcasted by a node to all active server nodes.

      Return Message is the m...
