    Abstract: Secured transmissions between a client and a server are detected, a policy formulated whether encrypted material needs to be decrypted, and if content is to be decrypted it is, using decrypting information obtained from the client and server. Resulting plain test is then deployed to an entity such as a processor, store or interface. The plain text can be checked or modified. The transmission between client and server could be blocked, delivered without being decrypted, decrypted and then re-encrypted with or without modification. Each transmission is given an ID and a policy tag.

    Abstract: A VIRTIO Relay Program allows packets to be transferred from a Network Interface Device (NID), across a PCIe bus to a host, and to a virtual machine executing on the host. Rather than an OvS switch subsystem of the host making packet switching decisions, switching rules are transferred to the NID and the NID makes packet switching decisions. Transfer of a packet from the NID to the host occurs across an SR-IOV compliant PCIe virtual function and into host memory. Transfer from that memory and into memory space of the virtual machine is a VIRTIO transfer. This relaying of the packet occurs in no more than two read/write transfers without the host making any packet steering decision based on any packet header. Packet counts/statistics for the switched flow are maintained by the OvS switch subsystem just as if it were the subsystem that had performed the packet switching.

    Abstract: A method and apparatus for improving channel estimation within an OFDM communication system. Channel estimation in OFDM is usually performed with the aid of pilot symbols. The pilot symbols are typically spaced in time and frequency. The set of frequencies and times at which pilot symbols are inserted is referred to as a pilot pattern. In some cases, the pilot pattern is a diagonal-shaped lattice, either regular or irregular. The method first interpolates in the direction of larger coherence (time or frequency). Using these measurements, the density of pilot symbols in the direction of faster change will be increased thereby improving channel estimation without increasing overhead. As such, the results of the first interpolating step can then be used to assist the interpolation in the dimension of smaller coherence (time or frequency).
