Abstract: A policy server operates to configure differentiated services over multi-protocol label switching (Diffserv/MPLS) in a communications network. The policy server enables the definition and deployment of a customer policy, a network policy and a mapping policy. The policy server is arranged to create a group of MPLS tunnels, and associate the tunnels to the mapping policy and the customer policy. The customer policy includes a tunnel group identifier and a tunneling mode, and maps customer traffic to MPLS tunnels. The policy server translates the customer policy, the network policy and the mapping policy into device-specific commands, and then deploys the device-specific commands to the network interfaces of the affected network devices.

Abstract: A policy server is arranged to construct device-neutral policies for configuring CBR for MPLS traffic engineering across a network. The policy server translates the device-neutral policies into device-specific commands (e.g. link attribute definitions and affinity profiles). The policy server defines the link attributes, assigns the link attributes to network interfaces, establishes affinity profiles and attaches the affinity profiles to MPLS tunnels. The link attribute definitions and affinity profiles are shared across the network to construct the policies such that IP operators can configure CBR easily across a network.

Abstract: There is disclosed a method and apparatus for controlling service level requirements between a communication network and a user equipment associated with an end-user connected in the communication network, in which the user equipment communicates with an external service via the communication network, the method comprising determining the end-user service level in dependence on a service level specification determined by the communication network and the external service.

Abstract: Mechanisms for QoS mapping rules on a mobile network between a UMTS layer and an IP layer are provided. A policy server is coupled to the SGSNs and GGSNs on the mobile network and maintains a centralized location for layer QoS mapping on the mobile network. Three mapping mechanisms have been provided, including an out-sourcing mechanism, a provisioning mechanism, and a hybrid mechanism. The out-sourcing mechanism uses the policy server to handle PDP context events and supply the appropriate rules to the appropriate support node. Under the provisioning mechanism, the policy server pushes down the corresponding mapping rules to each support node across the network in advance of any PDP context event. The hybrid mechanism utilizes a combination of the out-sourcing mechanism and the provisioning mechanism. The mechanisms ensure consistent UMTS layer QoS to IP layer QoS mapping across a mobile network.

Abstract: In mobile IP networks, when a mobile node (MN) moves from one cell to another, handover occurs. The result of the handover is that the MN connects to the network through a new access router (AR). The handover may occur between access routers of the same or different administrative domains. In all cases, the information related to the mobile node has to be transferred from the old AR to the new AR in order to minimize the effect of the change of access routers. This is the so-called context transfer.

Abstract: A method (1000) of estimating the delays that data packets experiences along a path in an IP network is presented. The method involves sending probe packets (102), transmitted along the same path as the data whose delays are to be estimated, with a frequency dictated by statistics that include Poisson statistics. Information obtained about the delays in the probe packet transmissions may be used to estimate data delays.
