Virtualization is the key technology of cloud computing. Network virtualization plays an important role in this field. Its performance is very relevant to network virtualizing. Nowadays its implementations are mainly based on the idea of Software Define Network (SDN). Open vSwitch is a sort of software virtual switch, which conforms to the OpenFlow protocol standard. It is basically deployed in...

Network processors (NPs) are programmable devices with special architectural features that are optimized to perform packet-processing functions. They have emerged to cope with the ever-changing networking applications that are becoming increasingly complex. NPs are expected to become the silicon core of network equipments that require a high degree of flexibility to support evolving network ser...

Network processors have great potential to combine high performance with increased flexibility. These multiprocessor systems consist of programmable elements, dedicated logic, and specialized memory and interconnection networks. However, the architectural complexity of the systems makes programming difficult. Programmers must be able to productively implement high performance applications for n...

Application-specific instruction-set processors (ASIP) are widely used in network processors. With a high demand from the market for faster new product development, retargetable compilers, and the associated knowledge, become essential for development. Based on the LCC retagetable C compiler, we added an ASIP target derived from the DLX instruction set, which was successfully used in a network ...

Network processors (NPs) typically contain multiple concurrent processing cores. State-of-the-art programming techniques for NPs are invariably low-level, requiring programmers to partition code into concurrent tasks early in the design process. This results in programs that are hard to maintain and hard to port to alternative architectures. This paper presents a new approach in which a high-le...

The electronics industry is full of examples of devices which contain one or two “special-purpose” chips. Your computer probably has a modem that is implemented with a single chip and a few analog components. It probably also contains a dedicated graphics processor responsible for driving your display. In networking, vendors have long since realized that in order to design highly efficient rout...

Network processors (NPs) are designed to provide both performance and flexibility through the implementation of both parallel and programmable architectures. Typically, such processors encompass a parallel processor core with several memories and specialized co-processors. A common task performed by such processors is packet processing that is both complex and highly repetitive. Consequently, t...
