Disclosed is a system and method for optimization of data transfer to a software service. In exemplary embodiments, a computer-implemented method for determining a transit appliance for data traffic to a software service through one or more interconnected networks comprising a plurality of network appliances, comprises determining performance metrics for each of the plurality of network appliances to at least one IP address associated with the software service, and selecting a transit appliance for data transfer to the IP address, the selected transit appliance based at least in part on the performance metrics.

Determining a transit appliance for data traffic to a software service

Disclosed is a method for data traffic optimization within a virtual environment. The method may be implemented within a data center hosting virtual machines and using virtual switches for routing data traffic. The method includes instructing a virtual switch associated with a virtual machine to redirect one or more data packets directed to or from a first address associated with the virtual machine to a second address associated with data optimization virtual machine, wherein the redirection is based at least in part on an access control list, receiving, at the data optimization virtual machine, the one or more data packets redirected by the virtual switch, selectively performing one or more transformations on the one or more data packets to create one or more transformed data packets, and transmitting the one or more transformed data packets to the first address.

Workload optimization in a wide area network utilizing virtual switches

The present invention provides methods and apparatuses for interfacing high-layer applications to Link Capacity Adjustment Scheme (LCAS) on Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) edge nodes. These applications include high-level control protocols, such as Generalized Multiprotocol Label Switching (GMPLS) and Optical Switching and Routing Protocol (OSRP), and user-initiated cross-connect creation and termination. The present invention provides a mechanism that is capable of mapping SONET/SDH connections to Virtual Concatenated Groups (VCGs), thus enabling an efficient interface for operators to control and manage the connections via LCAS. As part of the mechanism, the existing LCAS protocol state machine is enhanced such that the operators can shut down bi-directional SONET/SDH flows from a single edge node, as opposed to from both source and sink nodes, as provided for by existing specifications.
