Abstract: The subject disclosure relates to a method for instantiating cloud resources that are provided as service virtual machines. In one embodiment, a cloud service management system maps each one of the multiple abstraction layer slots to a virtual context of a logical resource. The virtual context is hosted by a respective virtual machine that is part of a pool of virtual machines. The system identifies an available abstraction slot from the multiple abstraction layer slots and reserves the slot so that the corresponding virtual context of the logical resource can be served to a requesting device. The system then marks the available abstraction layer slot as unavailable. Systems and computer readable media are also provided.

Abstract: A probing method, arrangement, and system for estimating a condition, such as available bandwidth, of a data path in a communication network including multiple nodes are described. A probe-packet sender node transmits probe packets with a sent inter-packet separation and a time-to-live towards an intermediate node. Control message packets are generated by the intermediate node when the time-to-live expires. The probe-packet sender node receives the control message packets and calculates a received inter-packet separation. An estimate of the data path condition can be generated based on the sent inter-packet separation and the received inter-packet separation.

Abstract: A system and method for determining end-to-end available bandwidth of a path in a packet-switched communication network. A multi-rate packet chirp injector injects probe traffic packets at different probing rates, u, into the network utilizing a probe chirp. A receiver samples time separation of the probe traffic packets to generate time-separation samples, which are used to calculate relative inter-packet separation strain, ?, samples at different probing rates. An Expectation-Maximization, EM, analyzer utilizes an EM algorithm to identify useful strain ? samples and to estimate parameters of a line l2 representing a direct linear relationship between the probing rate and the inter-packet separation strain ? at probing rates greater than a break point. A filter such as, for example, a Kalman filter then determines the available bandwidth of the network path based on the estimated parameters of the line l2.
