Problems solved by technology

[0009] However, existing known ATCA node card boards only support a topology switching interface, such as full-mesh (Full-mesh) topology, single star (Single star) type topology, double star (Dual star) type topology, double-double star ( Dual-Dual-star) topology
Although some ATCA node card boards can support the switching interface of multi-topology mode, the multi-topology mode is limited to full mesh topology or single-star topology / double-star topology / double-double-star topology connection mode, and for each The use of communication links (channel) and communication ports (port) in this topology mode is fixed, and users can only configure according to several fixed methods, but cannot adjust according to actual application requirements

Embodiment Construction

[0042] figure 2 It is a schematic diagram of the flexible switching interface architecture of the node card board of the present invention. refer to figure 2 , the elastic switch interface architecture of the node card is used in conjunction with the chassis bottom plate 211 and the multiple physical layers 214a of the node card 214 . The flexible switching interface provides n communication links CH between the m physical layers 214a on the node card 214 and the chassis bottom plate 211 1 -CH n middle communication port P 11 -P 1i ,...,P n1 -P ni corresponding to the route.

[0043] The elastic switch interface architecture of the node card includes an elastic switch interface unit 203 and a control unit 205 . The flexible switching interface unit 203 includes a switch 203a and an electronic keying component 203b. The control unit 205 controls the switcher 203a and the electronic keying component 203b through the control signals A[1:s] and B[1:e] respectively.

Abstract

The invention discloses an elastic exchange interface architecture for a node clipboard and a using method. The elastic exchange interface architecture comprises an elastic exchange interface unit and a control unit. The elastic exchange interface unit comprises a switcher and an electronic key assembly. The control unit controls the elastic exchange interface unit after the control unit receivesa control signal from an external communication server; at the same time, the control unit respectively controls the switcher and the electronic key assembly through the control signal. The elastic exchange interface architecture is used together with physical layers of a case bottom plate and the node clipboard, can allow the physical layers to correspond to the route of a communication port in a communication link of the case bottom plate, thereby being capable of supporting the multi-topology mode; and an on-line adjustment to the link / port assignment of the communication link can be made according to the bandwidth demand of the actual application to ensure that the use of the bandwidth achieves the optimization.

Description

technical field [0001] The invention relates to a flexible switching interface architecture (fabric interfacing architecture) of a node blade, which is used in conjunction with a node blade and a chassis backplane. Background technique [0002] With the vigorous development of various new and diversified network application services, a high-speed, stable, reliable, and continuous and uninterrupted network environment and services have become an indispensable basic demand for enterprises and individual customers. Various network application services such as Voice over Internet Protocol (VoIP), video conferencing, multimedia entertainment, and enterprise electronic data exchange must rely on reliable network connections and stable and predictable performance. Therefore, the implementation of the above-mentioned various network application services must rely on a stable and reliable network infrastructure. [0003] However, in the entire network infrastructure, for each compon...
