Abstract: Most of the internet traffic today is carried out via the Transmission Control Protocol (TCP). The main advantage of TCP is that it provides reliable data transfer to the application layer and simplifies programming. The protocol maximizes data throughput but may also lead to noticeable transmission delay in wide area networks (WAN). A client-server based medical image viewing system is disclosed that achieves high data throughput over TCP without impacting responsiveness. Special timestamp messages inserted into the data stream allow the system to detect situations where network latency increases noticeably and to obtain a reliable estimate of sustained transfer bandwidth. The system applies a feedback scheme that avoids network delays by limiting send bandwidth. In addition other parameters, in particular image compression settings, are dynamically adjusted depending on current network quality.

Abstract: Some of the present implementations provide a method for a user equipment (UE) for performing a handover procedure with minimum mobility interruption. The method receives, at the UE, a reconfiguration message that has an indicator for performing a dual-connectivity based (DC-based) handover procedure.

The PDCP entity maintains a plurality of security keys to decipher PDCP packets received from at least one of a source base station and a target base station during the handover procedure and while the UE is transitioning from the source base station to the target base station.

Abstract: A network interface controller (NIC) capable of facilitating fine-grain flow control (FGFC) is provided. The NIC can be equipped with a network interface, an FGFC logic block, and a traffic management logic block. During operation, the network interface can determine that a control frame from a switch is associated with FGFC.

The FGFC logic block can insert information from the control frame into an entry of a data structure stored in the NIC. The traffic management logic block can identify the entry in the data structure based on one or more fields of a packet belonging to the flow. Subsequently, the traffic management logic block can determine whether the packet is allowed to be forwarded based on the information in the entry.

The line rate classification circuit can place a network packet on one of the ingress queues based on the network packet's packet contents. A buffer scheduler can select network packets for processing by a sub line rate packet processing circuit based on the priority levels of the ingress queues.

Abstract: Implementations of the present disclosure are directed to systems and methods for flow control using a multiple flit interface. A credit return field is used in a credit-based flow control system to indicate that one or more credits are being returned to a sending device from a receiving device. Based on the number of credits available, the sending device determines whether to send device or wait until more credits are returned. The amount of buffer space used by the receiver to store the packet is determined by the number of transfer cycles used to receive the packet, not the number of flits comprising the packet. This is enabled by having the buffer be as wide as the bus. The receiver returns credits to the sender based on the number of buffer rows used to store the received packet, not the number of flits comprising the packet.

Abstract: Various embodiments providing for an indicator (termed the “Traffic Category Indicator,” TCI) to be encoded into packets, different values of which can be used, e.g., to distinguish Traffic Engineered (TE) packets and non-TE packets. In an example embodiment, the TCI can be used, e.g., to configure a network node to implement different packet queues, on each link, for TE packets and non-TE packets. In embodiments corresponding to the DiffSery TE paradigm, a node can be configured to implement different queues within each Forwarding Class for each link, said different queues distinguished by different respective TCI values. Example benefits of TCI include, but are not limited to fate separation of TE and non-TE packets in a node. The TCI concept can beneficially be applied to different packet-switching technologies supporting Source Routing, such as the IP, MPLS, Ethernet, etc.
