Abstract: The present invention provides a better solution to the problem of reporting to the transmitter the data received by a receiver in the field of data communications. This is achieved by reporting the status of the receivers' window. The cumulative sequence number is placed in the first field of the acknowledgement report as per the present invention. As per prior negotiation, the optional field of missing and received span pairs is placed after that. The first missing span length occurs after that. The next received span length is placed after that. Thereafter, the next missing span length and the received span lengths are placed one after the other. The last received data span is acknowledged in the last field. One optional field can occur either before or after this layout to represent the receiver open window status.

Abstract: A system and method of providing a reliable and efficient multicast data transfer mechanism in a communication network. The mechanism includes a plurality of computer nodes and one or more data system managers wherein each of computer nodes and each of data system managers are connected through the said communication network. The method generally comprises the steps of setting up of an association among one or more computer nodes as senders and one or more computer nodes as receivers using a combination of unicast and multicast protocols and transmitting one or more packets of data through the said multicast protocol by one or more senders to one or more receivers. The receivers may collaborate among themselves to ensure delivery of said one or more packets of data reliably to the collaborating receivers.

Abstract: An example method is provided and includes receiving a request to issue a facet; identifying an endpoint with a resource for which the facet is valid; identifying a set of actions capable of being performed on the resource; creating the facet using the set of actions; and issuing the facet. In other embodiments, the method may include receiving an initial request from an entity for the facet; determining whether the entity has authorization to make the initial request; and request a facet server module to issue the facet. In yet other embodiments, the facet has a condition, and the condition is at least one of a count of use, a time duration, and a periodic time duration. Additionally, in certain cases, determining whether the entity has authorization to make the initial request comprises evaluating validity information against a policy.

Abstract: An example method is provided and includes intercepting an action request from an entity for an action to be performed with respect to a resource in a cloud environment, where the action request comprises a resource facet that controls access to the resource. The method also includes determining whether the resource facet is valid for the action by evaluating a policy associated with the resource; and allowing the action.
