A distributed implementation method and system of multiple CPUs in a passive optical network

Abstract

The invention discloses a distributed implementation method and system of multiple CPUs in a passive optical network, which relates to the field of passive optical networks. The method includes the following steps: setting a main CPU and at least one backup CPU on a service disk, and Each CPU divides the controlled hardware resources; establishes a remote process between the main CPU and each standby CPU, between the main CPU and the hardware resources controlled by it, and between each standby CPU and the hardware resources controlled by it Call the RPC channel to realize the remote procedure call of the interface between business modules; the main CPU receives the request sent by the control panel, and calls the corresponding interface between business modules; the interface between business modules determines the CPU that executes the request and is executed by the CPU Interface logic, the main CPU will return the returned results and output parameters to the control panel. The invention can well meet the requirement of multi-chip service management.

Description

technical field [0001] The invention relates to the field of passive optical networks, in particular to a distributed realization method and system of multiple CPUs of passive optical networks. Background technique [0002] Current broadband access technologies are mainly classified into copper wire access technologies, such as various DSL (Digital Subscriber Line, digital subscriber line) technologies and optical access technologies. Among them, the passive optical network (PON, Passive Optical Network) technology is a point-to-multipoint transmission optical access technology, mainly including Ethernet passive optical network (EPON, Ethernet Passive Optical Network) and gigabit passive optical network ( GPON, Gigabit Passive Optical Network), etc. Such as figure 1 As shown, the PON system is generally composed of an OLT (Optical Line Terminal, optical line terminal), an ODN (Optical Distribution Network, optical distribution network) and an ONU / ONT. [0003] According t...

Problems solved by technology

However, at present, business disks are all single-CPU solutions. Different hardware chip resources (including but not limited to PON MAC, forwarding, memory, etc.) are all processed by a single CPU. In order to meet the high bandwidth requirements of a single business disk, it is necessary to introduce multi-chip multi-CPU solution solution, but the CPU centralized processing solution for existing business disks cannot meet the needs of multi-chip business management
