Abstract

The invention discloses a switcher control method and device. The method comprises the steps that a switcher software layer obtains an upper layer control instruction used for controlling hardware operation; the switcher software layer reads a hardware identification, control parameters and a control function identification of hardware operation to be controlled according to the upper layer control instruction; switcher software compiles the upper layer control instruction into a hardware control instruction according to the hardware identification, the control parameters and the control function identification and transmits the hardware control instruction to a switcher hardware layer; the switcher hardware layer calls hardware drive according to the hardware control instruction and executes the hardware operation. The switcher control method and device solves the problem that the adapting workload of the switcher software layer is large, and therefore the application rate of a switcher is increased.

Description

technical field [0001] 本发明涉及交换机技术领域,尤其涉及一种交换机控制方法及装置。 Background technique [0002] 目前,在整个交换机的生态链中,是一个封闭的几家商用厂商主导市场的状态,比如、思科、juniper、华为和华三等,这必然造成用户需要支付昂贵的成本,同时无法对网络设备的转发、控制策略以及各种功能逻辑进行定制和开发。 [0003] 业界也开始探讨是否可以把交换机的生态系统打造成类似服务器的生态系统,有原始设计制造商(OriginalDesignManufacturer,ODM)、原始设备制造商(OriginalEquipmentManufacturer,OEM)专门负责底层的交换机硬件设计,上层有可以商用的交换机操作系统,用户可以自行进行选择相应的交换机操作系统和底层硬件,这样将大大降低用户成本,同时,加快整个产业的标准化,提升生产制造的效率。 [0004] 基于以上的设想,业界开始出现类似xorp、cumulus之类的商用交换机操作系统,同时也出现一些ODM专门从事硬件白牌机的代工,比如广达、富士康、天宏等,甚至一些大的互联网公司也开始定制研发自己的交换机操作系统,因为不同硬件ODM的硬件设计不同,此类的交换机操作系统需要逐一适配各种ODM的硬件,这样就提升研发的成本并且降低了研发效率。 [0005] 另外,Facebook主导的Oracle数据库认证专家(OracleCertifiedProfessional,OCP)中提出一种建议方案,即开发一个嵌入式操作系统之上、交换机操作系统之下的软件抽象层,通过在这个抽象层去适配多家的第三方软件厂商,其会针对市场上主要的ODM硬件(包括交换芯片asic,电源、风扇、端口计数等各种I2C),进行适配开发。 [0006] 以上方案虽然能够解决交换机操作系统到底层硬件的兼容适配问题,但仍需要在中间抽象层针对各种的硬件进行兼容适配,同时在抽象层上运行着用于和上层交换机逻辑通信的代理agent,也可以理解为一些虚拟驱动器Daemon守护进程,通过这些守护进程来对上层的交换机操作系统进行硬件的无关性和封装。这些做法都不便于快速扩展整个生态链的底层硬件提供商,并且中间层的代码会相当庞大,增加代码维护的代价。 Contents o...
