Embodiment Construction
[0064] Embodiments of the present application provide a load sharing method, device, and network system, which are used to realize non-blocking exchange of traffic while saving network resources.
[0065] As the amount of network data continues to increase, for network devices such as network switching devices, their switching capabilities need to be continuously improved. The switching capability of a network device is related to the number of nodes with data switching capabilities in the network device. It should be noted that a node mentioned in the embodiment of this application represents a whole silicon chip or wafer ( A basic dicing unit within a wafer, such as a die. A node can be packaged in a switch chip in a network device, such as figure 1 shown. The more nodes included in the network device, the stronger the switching capability that the network device can provide. When the network device includes multiple nodes, each network device may include multiple switch ch...

The invention discloses a method, equipment and system for realizing load balancing, which are applied to a four-node body network structure. The nodes in the four-node body net structure are mutually connected in pairs, and the nodes are crystal grains. The four-node body network structure comprises a source node and a destination node. The method comprises the following step: when the bandwidth occupied by the incoming flow which flows into the source node and is sent to the destination node is greater than the bandwidth of an exchange side link between the source node and the destination node, the source node at least selects two transmission paths to send the incoming flow to the destination node. When the bandwidth occupied by the incoming flow is smaller than or equal to the bandwidth of an exchange side link between the source node and the destination node, the source node transmits the incoming flow through a direct link between the source node and the destination node. According to the method, network resources can be saved while traffic non-blocking exchange is realized, and a certain network low-delay requirement is met.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a load sharing method, device and network system. Background technique [0002] Early networks had relatively small bandwidth requirements for a single network switching device, and usually only one switching chip was included in a switching device. Such as figure 1 As shown, only one node is packaged inside the chip. The node refers to a basic dicing unit, such as a die, in a whole silicon chip or a wafer in the semiconductor process. With the development of technology, the design of single-device, single-chip, and single-node gradually cannot meet the rapid growth of the network's demand for switching bandwidth of switching devices. Therefore, various designs to improve the switching capabilities of devices have emerged. For example, multiple switching devices form a small ring network system, each switching device contains 1 or 2 switching chips, and ea...
