Abstract: Systems and methods for achieving high utilization of a network link are provided. A first communication protocol can be selected for transmitting network flows of a first type. A first quality of service can be assigned to network flows of the first type. A second communication protocol can be selected for transmitting network flows of a second type. A second quality of service, lower than the first quality of service, can be assigned to network flows of the second type. A first percentage of available bandwidth can be allocated to the network flows of both the first and second types. The remaining bandwidth, plus a second percentage of available bandwidth, can be allocated to the network flows of the second type, such that the total allocated bandwidth exceeds the available bandwidth of the network link.

Abstract: The present invention pertains to the allocation of bandwidth on a global large scale network. Systems and methods are provided to base bandwidth allocation on the predicted bandwidth demands of the network users. In allocating bandwidth, each user is assigned a user weight value, and is to be allocated bandwidth in proportion to that value. In addition, the bandwidth allocation is enforced so as to ensure that bandwidth allocation policies are maintained.

Abstract: A method and apparatus are provided in which a source and target perform bidirectional forwarding of traffic while a migration guest is being transferred from the source to the target. In some examples, the migration guest is exposed to the impending migration and takes an action in response. A virtual network programming controller informs other devices in the network of the change, such that those devices may communicate directly with the migration guest on the target host. According to some examples, an “other” virtual network device in communication with the controller and the target host facilitates the seamless migration. In such examples, the forwarding may be performed only until the other virtual machine receives an incoming packet from the target host, and then the other virtual machine resumes communication with the migration guest on the target host.

Abstract: Systems and methods for compressing data in a network system communicated across a network are discussed. The network system may determine a data link characteristic for a data link between a source and a destination. A compression algorithm may be selected from among a plurality of compression algorithms based on the data link characteristic. A chunk of data may be compressed, using the selected compression algorithm, to be communicated over the data link. A compression ratio of the compressed chunk and the chunk uncompressed may be compared to a compression threshold. The compressed chunk may be provided, using the control circuitry, if the compression ratio is greater or equal to the compression threshold. The chunk uncompressed may be provided if the first compression ratio is less than to the first compression threshold.
