Abstract: Transmission of data over a serial link based on a unidirectional clock signal is provided. A unidirectional clock signal is generated based on a first clock of a master device. The unidirectional clock signal is sent to a slave device that is connected to the serial link. The master device transmits data to the slave device over the serial link based on the first clock. The slave device receives the unidirectional clock signal from a master device. The slave device transmits data over the serial link to the master device based on the unidirectional clock signal.

Abstract: A PCIe Fabric (100) is made up of two or more slices (104A, 104B), where each of the slices is directly connected to a processor (112A, 112B) and one or more clients (102A-102D). Each slice (104A, 104B) includes an Input/Output (10) tier switch (108A, 108B), a hub tier switch (106A, 106B), and target devices which may be one or more persistent storage modules PSM A - D (110A, 110B, 110C, 110D). Each IO tier switch may have multiple downstream ports, where one or more such downstream ports is connected, via crosslink, to a hub tier switch in a different slice. IO tier switch (108A) is configured to receive a transaction layer packet, TLP, from a client (102A, 102B), make a determination that an address in the TLP is not associated with any multicast address range in the IO tier switch (108A) and is not associated with any downstream port in the IO tier switch (108A), and, based on the determinations, route the TLP to a first hub tier switch (106A) via an upstream port on the IO tier switch. The first hub tier switch (106A) is configured to make a determination that the TLP is associated with a multicast group, and, based on the determination, generate a rewritten TLP and route the rewritten TLP to a target device via a downstream port on the first hub tier switch (106A). The rewritten TLP includes a new address but the same data payload as the original TLP. Accordingly, address-based routing may be used to achieve a fully-connected mesh between the tiers with all clients accessing all endpoints.

Abstract: The present invention discloses a method, an apparatus and a system for determining a service transmission path. The method includes: receiving a service chaining object sent by a client based on an expanded path computation element communication protocol (PCEP), wherein the service chaining object contains service processing capacities which service nodes need to provide when transmitting a service in a network; determining at least one service node matched with the service chaining object in the network according to service processing capacities which service nodes in pre-stored service node attribute information are capable of providing; and generating a service transmission path based on the determined service nodes, for transmitting the service initiated by the client. The problems of large flow pressure and low utilization rate of the service nodes deployed in the network may be well solved.

Abstract: A switch system allows free change of a grain degree of monitoring without being conscious of a routing control. For example, a control protocol of a transmitter is used based on the open flow (OpenFlow) technique to control the monitoring function of the switch system, and the centralized control of the monitoring can be realized as the whole network and the monitoring result is reflected on the routing control. Here, the switch has a flow table for packet transfer and a flow table for monitoring. Both of the tables are searched to one packet and a multi-hit operation is performed to execute the operation of each of the entries. That is, both the tables are searched and the packet is transferred according to corresponding flow entries.
