Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
55 words
A link manager comprising: detecting means for detecting what link is
installed; managing means for defining a plurality of link
metrics indicating characteristics of each said link
detected and managing data corresponding to said
respective link metrics on a table; and selecting means for selecting a link having link
metrics complying with a given condition.
Claim 2
Dependent Claim
30 words
The link manager according to Claim 1, wherein said
managing means generates a record comprised of the data
corresponding to said respective link metrics, for each
link on said table.
Claim 3
Dependent Claim
58 words
The link manager according to Claim 2, wherein when
a new link corresponding to neither said record is
detected, said managing means generates a record
corresponding to said new link and records data
corresponding to link metrics of said link and wherein
when a link corresponding to either said record becomes
undetectable, said managing means deletes said record.
Claim 4
Dependent Claim
83 words
The link manager according to either one of Claim 1
to Claim 3, which comprises: link metric rank assigning means for assigning
ranks to said respective link metrics, based on a
predetermined preference; and data rank assigning means for assigning ranks to
the data corresponding to said respective link metrics, wherein when said predetermined preference is
given, said selecting means selects a link
corresponding to a record having data with a highest
rank thus assigned, at a link metric with a highest
rank.
Claim 5
Dependent Claim
50 words
The link manager according to Claim 4, wherein when
there exist a plurality of records having data with the
highest rank thus assigned, said selecting means
selects a link corresponding to a record having data
with a highest rank thus assigned, at a link metric
with a next highest rank.
Claim 6
Dependent Claim
59 words
A link management method comprising: a detecting step of detecting what link is
installed; a managing step of defining a plurality of link
metrics indicating characteristics of each said link
detected and managing data corresponding to said
respective link metrics on a table; and a selecting step of selecting a link having link
metrics complying with a given condition.
Claim 7
Dependent Claim
32 words
The link management method according to Claim 6,
which comprises a step of generating a record comprised
of the data corresponding to said respective link
metrics, for each link on said table.
Claim 8
Dependent Claim
60 words
The link management method according to Claim 7,
which comprises a step wherein when a new link
corresponding to neither said record is detected, a
record corresponding to said new link is generated and
data corresponding to link metrics of said link is
recorded and wherein when a link corresponding to
either said record becomes undetectable, said record is
deleted.
Claim 9
Dependent Claim
83 words
The link management method according to either one
of Claim 6 to Claim 8, which comprises: a step of assigning ranks to said respective link
metrics, based on a predetermined preference; and a step of assigning ranks to the data
corresponding to said respective link metrics, wherein said selecting step comprises a step of,
when said predetermined preference is given, selecting
a link corresponding to a record having data with a
highest rank thus assigned, at a link metric with a
highest rank.
Claim 10
Dependent Claim
55 words
The link management method according to Claim 9,
wherein said selecting step comprises a step of, when
there exist a plurality of records having data with the
highest rank thus assigned, selecting a link
corresponding to a record having data with a highest
rank thus assigned, at a link metric with a next
highest rank.
Claim 11
Dependent Claim
130 words
A program configured to effect execution of the
following processes: a process of detecting what link is installed; a process of defining a plurality of link metrics
indicating characteristics of each said link detected
and managing data corresponding to said respective link
metrics on a table; a process of generating a record comprised of the
data corresponding to said respective link metrics, for
each link on said table; a process of assigning ranks to said respective
link metrics, based on a predetermined preference; a process of assigning ranks to the data
corresponding to said respective link metrics; and a process of, when said predetermined preference
is given, selecting a link corresponding to a record
having data with a highest rank thus assigned, at a
link metric with a highest rank.
Claim 12
Dependent Claim
50 words
The program according to Claim 11, which comprises
a process of, when there exist a plurality of records
having data with the highest rank thus assigned,
selecting a link corresponding to a record having data
with a highest rank thus assigned, at a link metric
with a next highest rank.
Claim 13
Dependent Claim
61 words
The program according to Claim 11 or Claim 12,
which comprises a process wherein when a new link
corresponding to neither said record is detected, a
record corresponding to said new link is generated and
data corresponding to link metrics of said link is
recorded and wherein when a link corresponding to
either said record becomes undetectable, said record is
deleted.
Claim 14
Dependent Claim
21 words
A computer-readable memory in which the program
as set forth in either one of Claim 11 to Claim 13 is
recorded.
