DEADLINE-AWARE NETWORK PROTOCOL

摘要

A deadline-aware network protocol is described. In an example, data transfer at a transport layer entity of a packet-based communication network is controlled by receiving a request for network resources for a data flow from a network element and allocating network resources to the data flow. The data flow comprises a number of data packets associated with an application, and the request comprises a factor relating to a time deadline associated with the application. The network resources allocated depend on the factor relating to the time deadline. In examples, the network resource can be a bandwidth or data rate allocated to the data flow, and the factor can be a data rate sufficient to complete the data flow within the time deadline. In examples, the network resources are allocated greedily, such that requests are fully satisfied whenever possible, and the network resources are fully utilized.

主权项

1. A system for controlling data transfer at a transport-layer entity of a packet-based communication network, comprising:
at least one memory; and at least one processor operable with the at least one memory to:
receive a request for network resources for a data flow from a network element, the data flow comprising a plurality of data packets associated with an application, and the request comprising a factor relating to a time deadline associated with the application, the request further comprising an allocated rate data structure, the allocated rate data structure including one or more data rate allocations associated with one or more of a plurality of network elements associated with the dataflow; anddynamically allocate network resources to the data flow based on the factor responsive to receiving the request by removing network resources from at least one other data flow such that every data flow is allocated at least a base data rate.
