    Abstract: A routing control method in software defined networking and an OpenFlow controller are provided. The method includes: receiving, by an OFC, a data packet reported by an OFS; determining, by the OFC according to a key value stored in a cache, whether the data packet is a repeated packet; and if the data packet is a repeated packet, delivering, by the OFC, the data packet to the OFS, and instructing the OFS to match a stored flow table to process the data packet or transmit the data packet through a corresponding port; or if the data packet is not a repeated packet, calculating, by the OFC, a routing policy for the data packet, and delivering a flow entry to the OFS according to the routing policy. In this way, for repeated packets, the OFC may calculate a routing policy only once, thereby reducing a calculation amount of the OFC.

  • Patent number: 9078166
    Abstract: A method and arrangement for employing media layer adaptation in a wireless communication of media in data packets from a sending node to a receiving node, by determining a fitting frame aggregation scheme in an effective and accurate manner. An arrival time AT and generation time GT are monitored for packets when received at the packet receiving node. A difference ATdiff in the arrival time of consecutive packets and a difference GTdiff in the generation time of the packets, are calculated. Then, an inter-arrival measure IA is calculated as the deviation between the arrival time difference ATdiff and generation time difference GTdiff. When the inter-arrival jitter exceeds a preset threshold (Th), a frame aggregation scheme is determined based on the calculated inter-arrival jitter IA and applied in the packet communication.

  • Patent number: 8804515
    Abstract: A technique is disclosed for controlling data packet transmissions from a server to a client having a client buffer in accordance with a waiting mode and a dynamic mode. The waiting mode is performed before packets containing data encoded subject to a current bit rate have reached the client buffer; the dynamic mode is performed otherwise. In the waiting mode, down-switches to lower bit rates are allowed but up-switches to higher bit rates are disabled. In the dynamic mode, up-switches and down-switches are both allowed, with adjustments in the bit rate of packets controlled based, in part, on the amount of data contained within the client buffer when packets containing data encoded subject to the current bit rate first reached the client buffer. The two modes help avoid unnecessary rate switches.

The transport protocol stack comprises a concurrent stack having an out of band thread pool and a non-out of band thread pool. A channel is formed with a thread from the non-out of band thread pool of the concurrent stack for each sender. Non-out of band messages are processed in parallel for each scope of an application with a non-out of band thread. Non-out of band messages pertains to processes of the application from a same sender. Processes from a scope of the application are unrelated to processes from another scope of the application. Non-out of band messages within a same scope are processed in a predefined order.

  • Patent number: 8767547
    Abstract: Conventional packet network nodes react to congestion in the packet network by dropping packets in a manner which is perceived by users to be indiscriminate. In embodiments of the present invention, indiscriminate packet discards are prevented by causing packets to be discarded according to bandwidth allocations that intelligently track flow sending rates. Flows are allocated bandwidth based on policy information. Where such policy information indicates that the flow should be treated as delay-sensitive, the present invention includes means to allocate an initial minimum rate that will be guaranteed and such flows will also have the use of an additional capacity that varies depending on the number of such flows that currently share an available pool of capacity. This provides a congestion alleviation method which is less annoying to users since communications that have been in existence for longer are less susceptible to component packets being deleted.

  • Patent number: 8761172
    Abstract: The embodiments of the present invention discloses a data switching method and a switching device, which relates to network technologies. The method is easy to implement, and saves system resources. In unicast switching, resource used for cells reordering at the egress is greatly reduced; in multicast switching, the scheduling is easy and the data pass rate is high. The data switching method includes: receiving a switching request for switching a cell; arbitrating the switching request and obtaining an arbitration result; and performing corresponding switching for the cell, where the switching includes unicast switching and multicast switching, according to the arbitration result.

  • Patent number: 8750296
    Abstract: A method is described to allow a device to retrieve a message, that is separated into a plurality of fragments, from a data source, wherein the method involves: establishing a first network connection with the data source; receiving a subset of the plurality of fragments; determining the first network connection has ended before completion of said message; establishing one or more subsequent network connections with the data source; and receiving any of the plurality of fragments not within the subset. The characteristics (for example: application protocol, security, speed, reach, bandwidth capability, cost of usage, network type, physical layer type, data-link layer type, or IP address of one or both of the first and second devices) of the first network connection can be potentially different than the subsequent network connections.

  • Patent number: 8750309
    Abstract: A method in a network element of a packet data network classifies a data packet for application of a packet data network policy. A root node compound bit mask is applied to bits of a received data packet. The data packet has data in a plurality of fields. The compound bit mask has a plurality of bit masks each having bits in a different data packet field. The masked bits of the compound bit mask are applied to root node bit tables, one for each bit mask of the compound bit mask. A branch node from the root node is selected based on a bit table look up.

  • Patent number: 8724658
    Abstract: An output control unit outputs data of bit rate A to a first header-attaching unit and data of bit rate B to a second header-attaching unit. An instructing unit instructs the first or the second header-attaching unit to attach a header of bit rate being the least bit rate to the data of bit rate A or B. The first header-attaching unit creates a header of bit rate A, including an ID of a destination ONU of the data of bit rate A and information concerning the data length, and attaches the header of bit rate A to the data of bit rate A. The second header-attaching unit creates a header of bit rate A, including an ID of the destination ONU of the data of bit rate B and information concerning the data length, and attaches the header of bit rate A to the data of bit rate B.

    Abstract: The present invention discloses a method for processing broadcast packets/multicast control messages, comprising: replicating data to different broadcast/multicast logical channels in accordance with ONU types of users who join a VLAN when an OLT, on which a same port is connected to different types of ONUs, transmits the downlink broadcast packets/multicast control messages. The present invention also discloses a device for processing broadcast packets/multicast control messages. In accordance with the present invention, efficient processing of downlink broadcast packets and multicast control messages is realized when different types of ONUs coexist, unnecessary interference with ONUs from excessive data is avoided, and meanwhile the bandwidth between an OLT and an ONU can be utilized efficiently and meaningless bandwidth occupation by data streams can be avoided.

A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch.
