Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a data exchange system, a method and an apparatus for establishing the same, and a communication system.
Background
With the continuous development of electronic/communication technology, modern large-scale electronic equipment systems become very complex, and usually large-scale parallel computation is required to quickly find valuable target information while acquiring massive data. At this time, the internal data throughput of the entire system increases drastically, and very high requirements are placed on delay and bandwidth. For modern large electronic devices, very high speed large scale switching networks become the bottleneck of such systems.
Existing data exchange technologies include ethernet, FC (Fiber Channel, a widely used network technology for storage), RapidIO (fast IO, an interface standard for high performance microprocessors and system interconnection), and the like, and they adopt a topology structure including: star topology, ring topology, tree topology, bus topology (fig. 1), and a hybrid topology of two or more of the above.
Star-shaped structure
The star structure is a processing system taking one node as a center, and various types of network access machines are directly connected with the center node through physical links. The star structure has the advantages of simple structure, easy network establishment and relatively simple control. The method has the disadvantages of centralized control, heavy load of the main node, low reliability and low utilization rate of the communication line.
Bus structure
The bus structure is a commonly used method, which connects all network computers to a communication line, and in order to prevent signal reflection, the two ends of the bus are generally connected with matching line impedances of terminators. The bus structure has the advantages of high channel utilization rate, simple structure and relatively low price. The method has the disadvantages that only two network nodes can communicate with each other at the same time, the network extension distance is limited, and the number of network accommodating nodes is limited. If only one point on the bus has a connection problem, the normal operation of the whole network can be influenced.
Ring structure
The ring structure is a closed ring formed by connecting networked computers by communication lines. A ring topology is a point-to-point ring structure. Each piece of equipment is connected directly to the ring or through an interface device and drop cables. Ring topology networks are relatively simple to install initially. As the number of nodes on the network increases, the difficulty of reconfiguration increases, limiting the maximum length of the ring and the total number of devices on the ring. The fault point of the cable can be easily found. The range of devices affected by the fault is large and any error occurring on a single ring system will affect all devices on the network.
Tree-shaped structure
An extension of the star network topology is the star tree, as shown in the above figure. The connection of each Hub to the end user is still a star, and the concatenation of hubs forms a tree. However, it should be noted that the number of Hub cascades is limited and varies from manufacturer to manufacturer. The tree structure is a hierarchical centralized control type network, compared with the star type, the tree structure has the advantages of short total length of communication lines, lower cost, easy expansion of nodes and convenient path searching, but besides leaf nodes and lines connected with the leaf nodes, faults of any node or the lines connected with the node can affect the system.
Under the current electronic technology, the data throughput of a typical switch chip is about several GB (GigaByte, unit of computer storage capacity, 1GB 1024MB 2 byte) per second. Up to tens of GB is possible. And due to the limitations of chip package size, heat dissipation, and signal quality, higher bandwidth switching devices are becoming more and more difficult, or even impossible to implement. Therefore, for TB (Terabyte, unit of computer storage capacity, 1TB 1024GB ═ 2^40 bytes) level data exchange, the burden of the main switching node of the star topology is too heavy, and the data bandwidth far exceeds the capability of the prior art. Similarly, the bus type/ring type/tree type topology is not suitable for data exchange under the ultra-large bandwidth.
As described above, none of the existing solutions can meet the data exchange requirement of large-scale electronic information processing systems.
