Method and arrangement to reserve resources in an ip network
The invention relates to a method for pre-allocating network resources within an IP-network. Reserved resources are allocated based on usage history statistics when available usage history statistics is applicable to the resource reservation request. Network resources are allocated individually for said requested resource reservation when applicable usage history statistics is not available, and the usage history statistics is updated based upon the result of said individually allocated resources. The invention relates also to resource manager where said method is implemented and a computer program product that performs the steps of the method according to the present invention.
1 - 18 . (canceled)
19 . Method for allocating network resources within an IP network, the method is characterised in that it comprises the steps of:
allocating ( 801 ) at a first resource manager reserved network resources controlled by at least a second resource manager in advance before a session, that will use said resources, has started based on usage history statistics if available usage history statistics is applicable to said network resource reservation request,
allocating ( 802 ) network resources individually for said requested network resource reservation if applicable usage history statistics is not available, and
updating ( 803 ) said usage history statistics based upon said individually allocated network resources.
20 . Method according to claim 19 , wherein the method comprises the further step of:
manual adjusting usage history statistics.
21 . Method according to claim 19 , wherein said individually allocated network resources is allocated per reservation occasion.
22 . Method according to claim 19 , wherein said allocated reserved network resources is allocated based on usage history statistics per destination.
23 . Method according to claim 22 , wherein the time interval between each occasion, which network resources are allocated based on usage history statistics, may either be equal for all destinations or differ between the destinations.
24 . Method according to claim 22 , wherein said allocation of reserved network resources is further based on statistics for individual services.
25 . Method according to claim 19 , wherein the usage history statistics comprises any of the parameters a peak value, an average value or a variance.
26 . Method according to claim 19 , wherein said first and/or second resource manager is implemented within a server or a router in said IP network.
27 . A computer program product directly loadable into a server and/or router within an IP network comprising the software code portions for performing the steps of claim 19 .
28 . A computer program product stored on a computer usable medium, comprising readable program for causing a processing means within a server and/or router within an IP network to control the execution of the steps of claim 19 .
29 . A first resource manager in an IP-network is characterised in that it comprises means for allocating network resources within the IP network controlled by at least a second resource manager, said first resource manager comprises:
means ( 702 ) for allocating reserved network resources in advance before a session, that will use said resources, has started based on usage history statistics ( 708 ) when available usage history statistics is applicable to said network resource reservation request,
when applicable usage history statistics ( 708 ) is not available,
means ( 704 ) for allocating network resources individually for said requested network resource reservation, and
means ( 706 ) for updating said usage history statistics ( 708 ) based upon said individually allocated network resources.
30 . The first resource manager according to claim 29 , wherein said resource manager comprises means for manual adjusting usage history statistics.
31 . The first resource manager according to claim 29 , wherein the resource manager comprises means for allocating said individually allocated network resources per reservation occasion.
32 . The first resource manager according to claim 29 , wherein the resource manager comprises means for allocating said allocated reserved network resources based on usage history statistics per destination.
33 . The first resource manager according to claim 32 , wherein the time interval between each occasion, which network resources are allocated based on usage history statistics, may either be equal for all destinations or differ between the destinations.
34 . The first resource manager according to claim 32 , wherein said means for allocating network resources further comprises means for using statistics for individual services for said allocation network resource reservations.
35 . The first resource manager according to claim 29 , wherein the usage history statistics comprises any of the parameters a peak value, an average value or a variance.
36 . The first resource manager according to claim 29 , wherein said resource manager is implemented within a server or a router in said IP network.
