Embodiment Construction

[0079] The technical solution in this application will be described below with reference to the accompanying drawings.

[0080] figure 1 It is a schematic diagram of a network topology commonly used in data centers. It includes four parts: a core layer switch 110 , an aggregation layer switch 120 , an access layer switch 130 and a server 140 , and these four parts will be described in detail below.

[0081] Core layer switch 110 (including such as figure 1 The core layer switch 110a and the core layer switch 110b) shown in are switches placed at the core layer (network backbone). The core layer switches should all adopt a modular structure, have a considerable number of slots, and have strong network expansion capabilities.

[0082] Aggregation layer switch 120 (including such as figure 1The aggregation layer switch 120a to the aggregation layer switch 120d shown in , are aggregation points of multiple access layer switches. Aggregation layer switches can handle all traff...

Abstract

The invention provides a method for forwarding data. The method is applied to access layer switching equipment. In this method, first access layer switching equipment receives the first data packet through a target second port, wherein the first data packet carries a first identifier used for indicating second access layer switching equipment; wherein the second access layer switching equipment isconnected with a destination server of the first data packet; therefore, the first access layer switching equipment can determine a target first port connected with the second access layer switchingdevice through the core layer switching device according to the first identifier, furthermore, the first data packet can be sent to the second access layer switching equipment through the target firstport via the core layer switching equipment, so that the port for sending the first data packet does not need to be determined based on the indication of the centralized controller, and the data forwarding performance of the access layer switching equipment can be improved.

Description

technical field [0001] The present application relates to the communication field, and more specifically, relates to a data forwarding method and an access layer switching device. Background technique [0002] In a traditional data center, multiple servers are connected together through a fixed network topology, and data is transmitted between servers through access layer switches, aggregation layer switches, and core layer switches. However, the data flow between each pair of servers is uneven, resulting in an imbalance in the utilization rate of transmission data links in the network topology. [0003] In order to solve the unbalanced utilization rate of transmission data links in the network topology, a method of forwarding data is proposed, which introduces the core layer optical switch and changes the network topology in real time through optical switching technology. The bandwidth on the idle transmission data link is transferred to the busy transmission data link. ...
