Description
Technical Field
The disclosure relates to an embedded signal processing technology in the technical field of computers and the RapidIO network field, in particular to a method and a device for realizing hot backup of a RapidIO network system.
Background
RapidIO is a high-performance, low-pin-count, packet-switching-based interconnect architecture, which is an open interconnect technology standard designed to meet and future high-performance embedded system requirements. rapidIO is mainly applied to internal interconnection of an embedded system, supports chip-to-chip and board-to-board communication, and can be used as a backboard (Backplane) connection of embedded equipment.
The RapidIO protocol has very high advantages in terms of bandwidth, time delay, complexity, flexibility, reliability and the like of network interconnection for a high-performance embedded communication system, and is the best choice in embedded interconnection technology. Generally, rapidIO networks are composed of processing devices (PE, processing Element), which are mainly responsible for generating, transceiving and processing data packets, and switching devices (SWITCH), which accomplish the reception and forwarding of data packets. In the processing device, there is usually one Host node to complete network maintenance management work such as initial enumeration, route deployment, fault handling and the like of the RapidIO network.
From the reliability point of view, when the Host node itself or the network access of RapidIO fails, a hot backup mechanism is needed to ensure that the service and management of the RapidIO system cannot be out of control. The current mainstream hot standby technology is a dual hot standby system, and the implementation scheme can be divided into whether to rely on a third party arbitration mechanism. It is not difficult to find that the scheme adopting the third party arbitration mechanism is completely established on the premise that the third party arbitration can normally run, and the reliability of the whole system is not further improved; correspondingly, if a heartbeat communication mechanism is required to be established between the main machine and the standby machine without the aid of a third-party arbitration mechanism, when the main machine fails, the standby machine immediately starts a take-over program after sensing, so that the main machine and the standby machine are detected and switched, and the application is common in terms of overall cost and system complexity.
At present, a heartbeat communication mechanism between main computers and a standby computer in a RapidIO network mainly depends on additional hardware connection, such as General-purpose input/output (GPIO), and the like, so that the disadvantage in practical application is obvious, besides the increase of hardware cost, the hardware access of the main computers and the standby computers is difficult to dynamically adjust, and the overall network topology is greatly limited. The other implementation mode is to periodically send and maintain data packets such as a write, a doorbell and the like, and although extra hardware overhead is not required to be introduced, the data packets tend to occupy channel resources in a network, and because data interaction between forwarding and normal processing nodes of the data packets can generate conflict on routing configuration, the forwarding priority of the data packets is difficult to guarantee.

The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art as the case may be.
In the description of the present disclosure, it should be noted that, without conflict, embodiments of the present disclosure and features of the embodiments may be combined with each other.
Referring to fig. 1, fig. 1 is a flowchart of one embodiment of a method for implementing a hot-standby of a RapidIO network system according to the present disclosure. The method is suitable for the rapidIO network system, and the rapidIO network system can comprise a plurality of switching devices (i.e. switching devices) and a plurality of endpoint devices (i.e. processing devices), wherein the endpoint devices are connected with the switching devices. Here, no additional hardware connection is required, so there is no constraint on the topology design of RapidIO network, and all devices need to be connected through RapidIO channels. Among the plurality of endpoint devices, one endpoint device can be selected randomly or according to requirements as a main control processing node (i.e. a host), and the host is responsible for initial enumeration, configuration deployment, fault management and the like of the whole rapidIO network; and another endpoint device can be selected as a backup processing node (i.e. a standby machine) randomly or on demand, and similarly, the standby machine is selected without constraint, and the physical distance from the host machine is not required.
As shown in fig. 1, the implementation method of hot backup of the RapidIO network system in the embodiment of the disclosure mainly includes the following steps:
in the initial stage of the system, the host initiates network enumeration operation (or initiates preemptive network enumeration simultaneously) to complete device detection and discovery of the whole RapidIO network, and at this time, rapidIO channels of the host and other devices (including all switching devices and endpoint devices in the standby) in the RapidIO network are established.
And step 13, initializing heartbeat communication setting between the host and the standby, and circularly transmitting the multicast event controller as heartbeat by the host according to a fixed interval T.
In step 14, the standby machine records the receiving time T0 from the receiving of the first multicast event control Fu Shiji, and starts the standby machine control program to always detect whether there is a multicast event controller periodically received from the host machine.
In step 16, considering that jitter may exist in network transmission, the time limit TL for determining heartbeat loss may be properly widened compared with Ta, and the value may be customized according to a specific application scenario. That is, the standby machine may determine a value not smaller than Ta according to the application scenario, network jitter, and other factors, and the time limit TL for detecting the heartbeat loss of the host machine may be referred to as a heartbeat loss determination time limit.
And step 17, the standby machine always detects the heartbeat information (the multicast event controller) sent by the host machine, and judges whether the host machine fails or not according to the time interval of receiving the multicast event controller. Illustratively, a time interval Ti is recorded adjacent to two times; if Ti does not exceed TL, the host is considered normal, and circulation waiting is continued; otherwise, if Ti is greater than TL or the time interval from the last heartbeat exceeds TL, the host computer is regarded as fault, and the cycle detection is stopped.
And step 18, if the standby machine judges that the host machine has a fault, the standby machine starts a network take-over program, and the role finishes the switching from the standby machine to the host machine, namely, the standby machine is switched to be a new host machine, so that the original host machine is replaced to maintain and manage the whole rapidIO network.
In the following, an application scenario is taken as an example in conjunction with the RapidIO network topology example shown in fig. 2, to further explain the method of the embodiment of the present disclosure. The RapidIO network topology shown in fig. 2 includes a plurality of switching devices (switches, SWs) and a plurality of endpoint devices. The plurality of switching devices are respectively denoted by SW1, SW2, … …, SWn, (n is a positive integer). The plurality of endpoint devices include, but are not limited to, PPC (PowerPC, a Reduced Instruction Set (RISC) architecture central processor), DSP (digital signal processor ), FPGA (Field Programmable Gate Array, programmable array logic), etc. The plurality of endpoint devices include a Host (Host) and a standby.
To highlight implementation of the disclosed solution, the RapidIO network shown in the topology of fig. 2 does not list enough endpoint devices, and the implementation of the disclosed solution is as follows:
1) Initiating network enumeration by a Host to obtain network topology including all switching devices and endpoint devices, wherein a routing path of the Host and any device in the network is provided;
2) Planning a path between a Host and a standby machine based on the network topology obtained in the previous step: p= { ( SW 1,0, 5), ( SW 4,2, 9), ( SW 3,7, 4), ( SW 5,13, 5), ( SW 6,10, 2) }, including all exchanges of Host to the whole path of the standby, and corresponding ingress and egress ports; here, 5 in SW1 in ( SW 1,0, 5) represents port 5, and 2 and 9 in ( SW 4,2, 9) represent port 2 and port 9, respectively, which are not listed one by one;
3) Configuring each switching device in the path P one by one, and respectively starting multicast event controller forwarding enabling of the SW1 port 5, the SW4 port 9, the SW3 port 4, the SW5 port 5 and the SW6 port 2, so that the heartbeat communication transmission path between the main machine and the standby machine is established;
4) Initial setting of heartbeat communication between the main machine and the standby machine is started to be executed:
a) The host circularly transmits the multicast event controller according to a fixed interval T;
b) Recording time T0 when the standby machine receives the first multicast event control symbol, and starting a standby machine control program;
c) The standby machine receives the second multicast time control symbol time T1, and the like, and T2 and T3 are calculated, and an arithmetic average value Ta of time spent by the standby machine for transmitting the multicast event control symbol to the standby machine by the host machine for three times corresponding to the T1, the T2 and the T3 is recorded as a period for detecting the heartbeat of the host machine by the standby machine;
5) The method comprises the steps of integrating network transmission, service scenes and other conditions, and determining heartbeat loss judging time limit TL=2Ta;
6) So far, the host computer has ready all configuration about heartbeat communication, can start to deploy network data service, and the data interaction of the whole rapidIO network application layer is fully developed immediately; as the real-time load and link state of the network may change dynamically, the paths between the host and the network may also fail;
7) The standby machine always detects heartbeat information sent by the host machine and records a time interval Ti adjacent to two times, if the Ti does not exceed TL, the standby machine is regarded as normal to the host machine, and circulation waiting is continued; otherwise, when Ti is larger than TL or the time from the last heartbeat exceeds TL, the host computer is regarded as fault, and the cycle detection is stopped;
8) The standby machine starts a network take-over program, and the role finishes the switching from the standby machine to the host machine, so that the original host machine is replaced to maintain and manage the whole rapidIO network.
