Abstract: A fabric control protocol is described for use within a data center in which a switch fabric provides full mesh interconnectivity such that any of the servers may communicate packet data for a given packet flow to any other of the servers using any of a number of parallel data paths within the data center switch fabric. The fabric control protocol enables spraying of individual packets for a given packet flow across some or all of the multiple parallel data paths in the data center switch fabric and, optionally, reordering of the packets for delivery to the destination. The fabric control protocol may provide end-to-end bandwidth scaling and flow fairness within a single tunnel based on endpoint-controlled requests and grants for flows. In some examples, the fabric control protocol packet structure is carried over an underlying protocol, such as the User Datagram Protocol (UDP).

Abstract: This disclosure describes techniques that include performing cryptographic operations (encryption, decryption, generation of a message authentication code). Such techniques may involve the data processing unit performing any of multiple modes of encryption, decryption, and/or other cryptographic operation procedures or standards, including, Advanced Encryption Standard (AES) cryptographic operations. In some examples, the security block is implemented as a unified, multi-threaded, high-throughput encryption and decryption system for performing multiple modes of AES operations.

Abstract: Network access node virtual fabrics configured dynamically over an underlay network are described. A centralized controller, such as a software-defined networking (SDN) controller, of a packet switched network is configured to establish one or more virtual fabrics as overlay networks on top of the physical underlay network of the packet switched network. For example, the SDN controller may define multiple sets of two of more access nodes connected to the packet switched network, and the access nodes of a given one of the sets may use a new data transmission protocol, referred to generally herein as a fabric control protocol (FCP), to dynamically setup tunnels as a virtual fabric over the packet switched network. The FCP tunnels may include all or a subset of the parallel data paths through the packet switched network between the access nodes for a given virtual fabric.

Abstract: A network system for a data center is described in which a switch fabric provides full mesh interconnectivity such that any servers may communicate packet data to any other of the servers using any of a number of parallel data paths. Moreover, according to the techniques described herein, edge-positioned access nodes, optical permutation devices and core switches of the switch fabric may be configured and arranged in a way such that the parallel data paths provide single L2/L3 hop, full mesh interconnections between any pairwise combination of the access nodes, even in massive data centers having tens of thousands of servers.

Abstract: A method and apparatus for providing subscription-on-demand (SOD) services for a interactive information distribution system, where a consumer may subscribe to packages of on-demand programs for a single price and view the programs in the subscribed package at any time for no additional cost. The apparatus and method are embodied in a combination of software, which provides a so called navigator, and hardware, including a subscriber terminal that provides certain functionality for the navigator and service provider equipment that supports the functionality of the terminal. As such, graphical user interface functionality is distributed between the service provider equipment and subscriber equipment (subscriber terminal). Such distribution provides an enjoyable, real time interactive process for accessing SOD services that allows the subscriber to rapidly identify and access a subscription service.
