摘要:
Implementations of the present disclosure involve an apparatus, device, component, and/or method for a virtual output queue linked list management scheme for a high-performance network switch. In general, the linked list management scheme utilizes one or more look-ahead links associated with one or more descriptors in the linked list of descriptors that describe the storage of the incoming data packets to the switch. The look-ahead links allow the switch to schedule reads of memory locations included in the descriptors at the same speed at which the data packets are stored in memory.
摘要:
A node device (1A) receives a second ACK list in communication with an adjacent node (1B) and updates a first ACK list and a first summary vector on the basis of the second ACK list. The first summary vector, which indicates messages stored in a message buffer of the node device (1A), is transmitted to the adjacent node (1B) prior to transmission of the messages in the communication with the adjacent node (1B). The first ACK list indicates ACK messages recognized by the node device (1A). The second ACK list indicates ACK messages recognized by the adjacent node (1B). Each ACK message represents a message of arrival at an ultimate destination node via a DTN (100). In this way, for example, a copy having the same content as a message having arrived at an ultimate destination node can be prevented from being scattered in the Disruption Tolerant Network (DTN).
摘要:
A communication engine and a method thereof of chunk-based communication of binary Dynamic REST messages. The communication engine includes a port to receive one or more data streams. The communication engine having a first buffer to store a received first data stream and a received second data stream. The communicate engine includes a second buffer to store portions of a decoded message. The communication engine includes a processor configured to decode the received data stream buffered within the first buffer to produce a given decoded portion. The processor storing the given decoded portion to the second buffer where the processor initiates decoding of the received first data stream buffered within the first buffer prior to a complete receipt of the received second data stream.
摘要:
A system for managing data packets has multiple cores, a data buffer, a hardware accelerator, and an interrupt controller. The interrupt controller transmits a first interrupt signal to a first one of the cores based on a first hardware signal received from the hardware accelerator. The first core creates a copy of buffer descriptors (BD) of a buffer descriptor ring that correspond to the data packets in the data buffer in a first virtual queue and indicates to the hardware accelerator that the data packets are processed. If there are additional data packets, the interrupt controller transmits a second interrupt signal to a second core, which performs the same steps as performed by the first core. The first and the second cores simultaneously process the data packets associated with the BDs in the first and second virtual queues, respectively.
摘要:
A multicast rule is represented in a hierarchical linked list with N tiers. Each tier or level in the hierarchical linked list corresponds to a network layer of a network stack that requires replication. Redundant groups in each tier are eliminated such that the groups in each tier are stored exactly once in a replication table. A multicast replication engine traverses the hierarchical linked list and replicates a packet according to each node in the hierarchical linked list.
摘要:
A query inserter receives data elements having individual priority types for placement in a queue, and utilizes the priority types of the received data elements to determine placement in the queue relative to an initial location established when a first data element is placed in an empty queue in order to manage the queue with a combination of first-in first-out and last-in first-out queue functionality.
摘要:
Provided are a traffic management scheduling method and apparatus. The method includes: receiving an operation request, where the operation request comprises: a dequeue request or an enqueue request (S102); and performing a scheduling operation on a queue linked list according to the operation request, where the queue linked list comprises one or more active queues and one or more inactive queues (S104). The technical solution solves a technical problem in the related art that the increasing number of queues has an excessively high demand for buffer resources, resulting in traffic management difficulties, thereby saving storage resources required for buffering linked list information, and enhancing the performance of a traffic management system.
摘要:
A buffer memory is provided that comprises a plurality of memory elements for storing data elements in an order of arrival, wherein the plurality of memory elements have a variable size and wherein each memory element comprises a pointer (such as a next block starting index) to a memory element storing a next data element. Additionally, each memory element optionally further comprises a block size field indicating the variable size and/or a sequence number field indicating a sequence number of the corresponding data element. The buffer memory optionally comprises a largest sequence variable to store a sequence number of a data element in the buffer memory having a largest sequence number. The largest sequence variable is updated if a newly arrived data element has a sequence number that is larger than the largest sequence variable. A method is also provided for managing the disclosed buffer memories.
摘要:
Systems and methodologies that enhance a Tabular Data Stream (TDS) protocol by enabling efficient transmission of a row(s) with null columns(s). An identification component employs a bit map that can be positioned at beginning of a row, to indicate to the receiving side (e.g., a client) columns that are to be sent. Accordingly, by distinguishing columns that are null from columns that are not null—followed by sending columns that are not null—transmission resources can be effectively employed.
摘要:
Systems and methods can operate to transmit embedded control data (ECD) information within the payload of packet data. Payload packet data can contain a plurality of data elements of equal value. A transmitter can replace the repeating data elements with ECD information. A receiver can extract the ECD information and replace with the repeating data value to reconstruct the original. ECD information can be communicated between communication systems and between interfaces within a communication system.
