摘要： A method (300) of automatically discovering links between a first node of a first operating domain and a second node of a second operating domain of a communication network is disclosed. The method, performed in the second node, comprises receiving an in-band control message from the first node (302), the in-band control message being encoded using size of packets of the control message and providing information about the first node and a first interface used by the first node for sending the control message, and sending a link message to a control node (304), the link message comprising information received in the in-band control message and information about a second interface used by the second node for receiving the in-band control message.Also disclosed are corresponding methods (100, 200) of automatically discovering links between a first node of a first operating domain and a second node of a second operating domain of a communication network, the methods performed in a first node and in a control node. A control node (400, 700), first node (500, 800) and second node (600, 900), together with a computer program for carrying out methods of automatically discovering links between a first node of a first operating domain and a second node of a second operating domain of a communication network are also disclosed

摘要： Methods and apparatus are disclosed for obtaining and processing information from a predetermined portion of a header of a data item such as an IP packet transmitted via a communication network such as a packet network, the portion carrying a codepoint selected from a first set of codepoints each of which has a pre-defined meaning according to a first pre-defined communication protocol. The method comprises: receiving the data item; inspecting the header whereby to determine the codepoint carried by the predetermined portion thereof; identifying whether the codepoint is a member of a second set of codepoints, the second set comprising fewer possible codepoints than the first set; and in the event that the codepoint is identified as being a member of the second set, and in dependence on such an identification being made, interpreting that codepoint according to a different pre-defined communication protocol as having a different pre-defined meaning and routing the data item via the communication network via the second pre-defined communication protocol.

摘要： The present solution is directed towards systems and methods to more efficiently control a flow of a data stream traversing at least one intermediary on a network between a client and a server. A sender transmits a first message, comprising a first value of a bandwidth between the first intermediary and a second intermediary determined by the sender, to a first intermediary. The first intermediary establishes a next value of the bandwidth between the first intermediary and the second intermediary. The sender receives from the first intermediary responsive to the first message a second message comprising the established next value of the bandwidth between the first intermediary and the second intermediary. A data transfer manager of the sender, responsive to the second message determines a size of a portion of data queued for transmission to transmit to the first intermediary and a time for transmitting the portion of data queued.

摘要： Techniques are described herein for optimizing communications in a network. At a router in a virtual private network, a packet is received from a device in a subnetwork protected by the router. The router examines the packet to determine a source address that identifies the device and a destination address that identifies a destination network device for the packet. The router also analyzes the packet to determine a size of the packet and determines whether or not the size of the packet is larger than a maximum transmission unit size. If the size of the packet is larger than the maximum transmission unit size, the router encapsulates the packet with a header that includes the destination address and a new source address that identifies the router.

摘要： A device may store a credit value for each of multiple output components. The device may receive packets from a network device via an input component. The device may cause the input component to queue the packets. The device may selectively dequeue a packet from the input component, to be sent to an output component, based on whether the credit value for the output component satisfies a credit threshold. The device may send the packet to the output component based on a destination of the packet when the packet is dequeued from the input component. The device may determine a size of the packet after the packet is dequeued. The device may update the credit value for the output component based on the size of the packet. The device may output the packet to another network device via the output component.

摘要： A bridge device including first and second queues and a shaper. The shaper receives an indication of a first time corresponding to a beginning of a blocking band and transmits, during a first portion of a transmission interval, a frame of data from the first queue. The transmission interval begins at a second time subsequent to the first time and the blocking band extends from the first time into the first portion of the transmission interval. The shaper blocks a frame of data from the second queue during the blocking band in response to a determination that transmission of the frame of data will not be completed prior to the second time. The shaper transmits the frame of data from the second queue during the blocking band in response to a determination that the transmission of the frame of data will be completed prior to the second time.

摘要： A system and method for efficient transfer of data over a network. A data source and a destination are coupled to one another via a network. The data source is configured to transmit data to the destination and determine a network latency associated with the transmission. In response to determining a first transmission parameter may not be optimized, the source is configured to modify the first transmission parameter and evaluate its effect on data throughput. The source may repeat such modifications as long as throughput is increased. Once the first transmission parameter is deemed optimized, the source may perform a similar procedure for a second transmission parameter. In various embodiments, the first transmission parameter may correspond to a packet size and the second transmission parameter may correspond to a number of streams being processed by the source.

摘要： A system, method or computer readable medium to provide efficient congestion notification is described herein. In various embodiments, a packet is received at an intermediate node of one or more data center networks. A current queue length at the intermediate node is determined. A threshold value for the current queue length is tuned by dynamically computing an upper bound and a lower bound based at least in part on the network. The packet is marked to indicate possible congestion in the one or more data center networks when the current queue length exceeds the threshold value. In some embodiments, the packet is marked when it is being de-queued. In a further embodiment, Flexible Initial Packet Size (FIPS) may be utilized to improve the efficiency of the tuning.
