摘要:
A software program/software tools allows end user quality of experience to be quantified and translated into network conditions required to achieve that end user quality of experience. By focusing on the Quality of Experience (QoE) for the applications that will use the network rather than the traditional bottom up approach, and then looking to design the network based on those end user requirements, the network may be designed and/or operated to achieve a high quality of experience. The program and tools may be used at different phases of the networking cycle, including design, planning, deployment, and operational phases, to allow the QoE requirements to be obtained while optimizing network cost and utilization. A QoE server may be implemented off line and used for network design/planning, or may be included on the network to monitor the network and control operation of the network to achieve the intended QoE.

Domains (multiple collaborating service providers) create service offerings between pairs of edge nodes that interconnect with other domains in the network. The service offerings may specify the available bandwidth, quality of service, reliability, available security, price, subscriber and service contextual specific and other SLA information. When a new service is to be created, the service definition is used along with information about the available service offerings to determine a set of networks to implement the service. Information associated with the service offerings may be flooded to all other networks. Alternatively, the service offering information may be provided to a trusted third party (SLA broker) which may provide SLA services on the network to select sets of domains to implement inter-domain services, and may also proxy to set up the service for the SLA requesting party. A hybrid approach may also be used wherein some SLA information is flooded and other information is retained in secret and provided only to the SLA broker.

The present invention relates to a system and method for network performance management for monitoring performance of network applications. The system comprises a transmitter for sending one or more types of probe packets to the network, a receiver for receiving the one or more network probe packets from the network and for receiving one or more network application performance queries from one or more network applications, a processor connected to the transmitter and the receiver and operable to process network probe packets received by the receiver to generate network performance statistics for each type of probe packet and to look up the network application performance requirements of the one or more network applications and compare the network application performance requirements with the corresponding network performance statistics to determine whether the network application should access the network. Network performance statistics may be obtained using lean packet probes, using real traffic test streams or obtaining network performance statistics from a service provider. Thus by providing a probe, lookup, feedback methodology, network parameters, or network application requirements, may be adjusted to meet performance requirements of one or more network applications.

A content-centric-network (CCN)/named-data networking (NDN) system to support seamless mobility for a mobile node (MN) comprising a first point of attachment (PoA) configured to indicate to the MN that attaches to the first PoA one or more neighbor PoAs and to multicast an interest for content from the MN to the neighbor PoAs in a CCN or NDN when the MN starts a handoff procedure, and a second PoA from the one or more neighbor PoAs of the first PoA configured to receive the multicast interest from the first PoA, forward the interest to the CCN or NDN, receive content data from the CCN or NDN, and forward the content data to the MN.
