Network with a network wide extended policy framework

摘要

A network with a network wide extended policy framework comprising: path computation clients (PCCs), associated with at least one local policy enforcement point (PEP); path computation servers (PCSs), associated with at least one policy decision point (PDP). The PEPs and PDPs adapted to exchange attributes determined by at least one PDP. PDPs are adapted to identify network elements/network services requiring identical configuration parameters by evaluating parameters advertised in the network and update policy related to identified groups in case of configuration error. Updated policy is distributed by PDP in policy notification to PEPs associated with network elements/network services of identified group. The PEPs receiving policy notification comprising updated policy from PDP adapted to translate the updated policy into configuration settings of network elements/network services the identified group.

1. A network with a network wide extended policy framework comprising:
path computation clients each being associated with at least one local policy enforcement point; path computation servers associated with at least one policy decision point; wherein said policy enforcement points and said at least one policy decision point are adapted to exchange attributes which are determined by said at least one policy decision point; wherein said attributes are exchanged between the path computation clients and path computation servers and are advertised to the policy decision point; wherein said policy decision point is adapted to identify a group of network elements and/or network services requiring an identical set of configuration parameters by evaluating parameters advertised into the network and to update a policy related to said identified group in case of a detected configuration error; wherein said policy is undated dynamically in response to a detected real time or scheduled network event affecting a network element and/or a network service of the identified group, wherein said at least one policy decision point is associated with one or more network path computation servers (PCSs) for network policy management; wherein said updated policy is distributed by said policy decision point in a policy notification to the policy enforcement points (PEPS) associated with the network elements and/or network services of said identified group; wherein said policy enforcement points receiving said policy notification comprising said updated policy from said policy decision point are adapted to translate the received updated policy into configuration settings of said network elements and/or network services of said identified group; and wherein a path computation client of said network comprises a client application requesting a path computation to be performed by a path computation server.
