The first media converters are coupled to top networking ports, each of the first media converters including a first ASIC transceiver that has a circuit switch function. The second media converters are coupled to the first media converter via optical cables to receive the optical signals. Each of the second media converters includes a second ASIC transceiver that has a circuit switch function. The bottom networking ports are coupled to the second media converters. The first ASIC transceiver and the second ASIC transceiver are configured to transmit a signal from one of the top networking ports to any one of the bottom networking ports, and transmit a signal from one of the bottom networking ports to any one of the top networking ports.

摘要： Techniques and architectures for measuring available bandwidth. A train of probe packets is received from a remote electronic device. A network transmission delay for at least two packets from the train of probe packets is measured. Network congestion is estimated utilizing the at least two packets from the train of probe packets. An estimated available bandwidth is computed based on the network transmission and estimated network congestion. One or more network transmission characteristics are modified based on the estimated available bandwidth.

摘要： In an example, memory register interrupt based signaling and messaging may include receiving, at a control register of a receiver, a signal number from a sender, and copying, by a memory register interrupt management device of the receiver, the signal number to an associated status register of the receiver. Further, memory register interrupt based signaling and messaging may include generating, independently of the signal number from the status register, an interrupt to a central processing unit of the receiver, and triggering, based on the interrupt, an interrupt handler of the receiver to perform an action associated with the signal number.

摘要： An example system may comprise a set of network devices in a network topology, the network topology having a plurality of external links that connect to other networks, wherein the system comprises a processing resource to: assign multiple Internet Protocol (IP) addresses to one of the network interfaces of a client device; communicate the multiple IP addresses to a network interface of the client device; receive a packet from the one of the network interfaces, wherein the packet includes a source address that is one of the multiple IP addresses; select an external link of the plurality of external links based on the source address of the packet; and forward the packet via the external link of the plurality of external links.

摘要： A method may include determining whether a host destination address of a packet received at a particular switch of a switching fabric is associated with a virtual switch address. In response to a determination that the host destination address is associated with the virtual switch address, the method may also include encapsulating the packet with the virtual switch address as a destination fabric address, where the virtual switch address is associated with a virtual switch including a first physical switch and a second physical switch. The method may further include selecting one of the first physical switch and the second physical switch as a routing path. The method may further include routing the packet to the selected physical switch based on the virtual switch address and transmitting the packet from the selected physical switch to a client switch.

摘要： Systems and methods are provided for measuring available bandwidth available in a black box network by determining a probing rate of packet transmissions between a sender and receiver. The optimal probing rate and bandwidth estimate may be determined. Additional actions may be performed, like automatically rerouting packets and/or load balancing network traffic after the probing rate is determined.

摘要： Techniques and architectures for measuring available bandwidth. A train of probe packets is received from a remote electronic device. A received time for a first subset of the train of probe packets is measured. A change in capacity of the network path is determined based on the measured received time for the first subset of packets. Packets from the train of probe packets prior to the detected change in capacity of the network path are excluded to identify a second subset of packets. An estimated available bandwidth is computed based on the second subset of packets from the train of probe packets.

摘要： Techniques and architectures for measuring available bandwidth. A train of probe packets is received from a remote electronic device. A per-packet one-way delay (OWD) is calculated for at least two packets from the train of probe packets. An OWD threshold value is calculated based on the calculated OWD for the at least two packets from the train of probe packets. A packet pair is selected from the train of probe packets based on the per-packet OWD for each packet in the packet pair exceeding the OWD threshold value. An estimated available bandwidth is computed based on one or more transmission characteristics of the selected packet pair.
