Problems solved by technology

In other words, with the size of the current TCAM, due to the limited process entries in the memory, the number of visits between the switch and the control machine is frequent, which increases the delay of the packet
[0004] Moreover, the current switch does not consider the optimization problem of instant updating, deleting or adding process entries
Therefore, when the process entries are frequently changed, the efficiency of the switch will also be reduced

Embodiment Construction

[0012] figure 1 It is a structural diagram of the switch 100 of the software-defined network of the present invention. It is explained here that the method for accessing data of the switch disclosed in the present invention can be applied to different types of switches, and figure 1 The architecture of the switch 100 only represents an embodiment of the switch used in the OpenFlow protocol under a Software Defined Network (SDN), and cannot limit the scope of the present invention. The switch 100 includes a control circuit 11 and a chip circuit 10. The control circuit 11 may be an ASIC side (ASIC side) on the data plane, also known as an On-Chip side. The chip circuit 10 can be the CPU side on the control plane, also known as the off-chip side. The chip circuit 10 includes a plurality of first memories, for example, includes a first memory 12 for storing a Media Access Control Table (MAC Table), and a first memory 12 for storing an Internet Protocol Table (IPTable). The first ...

Abstract

The invention discloses a data access method of an exchanger. The method comprises the following steps: vectoring flow entries in order to generate flow entry vectors, comparing flow entry vectors with storage vectors of each first memory body in multiple corresponding first memory bodies in order to select temporary storage positions of flow entries, and transferring partial data in the first memory bodies to be stored in second memory bodies when first memory bodies are selected by the flow entries with the utilization rate exceeding the pre-set value.

Description

Technical field [0001] The invention relates to a method for a switch to access data, and more specifically, to a method for increasing the amount of access data by using a sub-process entry table. Background technique [0002] In recent years, with the vigorous development of cloud computing, virtualization (Virtualization) technology has become a hot research topic. Among them, host virtualization can transform a single physical host into multiple virtual hosts (Virtual Machine, VM) that operate together. Each host performs parallel computing to provide reliable service quality. However, the application of virtualization technology to cloud-level networks requires large computing power, memory, and data storage space. To this end, Stanford University has developed a software-defined network (Software Defined Network, SDN) system and formulated the OpenFlow architecture. The original goal was to extend the programmable programming feature of the switching circuit of the campus...
