Description

确定进入节能模式的网络装置的数量的方法及控制装置Method and control device for determining the number of network devices entering energy-saving mode

技术领域technical field

本发明涉及网络通信技术领域,特别是涉及一种确定进入节能模式的网络装置的数量的方法及控制装置。The invention relates to the technical field of network communication, in particular to a method and a control device for determining the number of network devices entering an energy-saving mode.

背景技术Background technique

网关设备的英文全称是Broadband Network Gateway(网关设备),是一种用于小规模用户,例如宽带家庭用户和小企业用户,来接入Internet(互联网)的网关设备。该设备的基本功能包括:对用户接入进行认证(authentication)、授权(authorization)和计费(accounting),为上线的用户分配IP地址。此外网关设备还可以处理如对用户接入带宽进行控制等相对复杂的事件。网关设备功能的扩展性以及在网络中的重要地位使其成为近年来城域网研究的焦点之一。The full English name of the gateway device is Broadband Network Gateway (gateway device), which is a gateway device for small-scale users, such as broadband home users and small business users, to access the Internet (Internet). The basic functions of the device include: authentication, authorization and accounting for user access, and assigning IP addresses to online users. In addition, the gateway device can also handle relatively complex events such as controlling user access bandwidth. The expansibility of the functions of the gateway equipment and its important position in the network make it one of the focuses of the research of the metropolitan area network in recent years.

网关设备是用户上网的必经之路,在接收用户上行流量的同时,将从互联网过来的下行流量发送给每个用户。在最近几年,由于新兴互联网业务,智能终端,视频等大流量业务的不断兴起和普及,用户对于上网带宽的需求逐年增大,导致经过网关设备的流量不断提高。与此同时,随着能源成本的持续增长,运营商的成本也随之不断提高。迫使运营商对不影响业务质量的前提下提高能效的解决方案的需求越发强烈。降低功耗,对于运营商而言是直接增加利润。The gateway device is the only way for users to go online. While receiving the user's uplink traffic, it sends the downlink traffic from the Internet to each user. In recent years, due to the continuous rise and popularization of emerging Internet services, smart terminals, video and other high-traffic services, users' demand for Internet bandwidth has increased year by year, resulting in continuous increase in traffic passing through gateway devices. At the same time, as energy costs continue to rise, so do operators' costs. Operators are increasingly demanding solutions that improve energy efficiency without compromising service quality. Reducing power consumption directly increases profits for operators.

降低功耗的最直接方式是将空闲的网关设备设为节能模式,现有技术中往往在网关设备完全没有负载时就将其设为节能模式,从而降低功耗,而负载有本身可负荷最大流量的一部分的其他网关设备则需继续工作。现有技术的这种网关设备的控制方法及装置只能够对完全没有负责网关设备进行处理,不能有效对负载有本身可负荷流量的一部分的其他网关设备的工作状态进行控制。The most direct way to reduce power consumption is to set the idle gateway device to the energy-saving mode. In the prior art, the gateway device is often set to the energy-saving mode when there is no load at all, thereby reducing power consumption, and the load itself can be the largest Other gateway devices that are part of the traffic need to continue working. The control method and device of such gateway equipment in the prior art can only handle the gateway equipment that is not in charge at all, and cannot effectively control the working status of other gateway equipment that has a part of its own loadable traffic.

Wherein, in this application scenario, the network device specifically selects a gateway device.

首先请参见图9,其中图9是本发明应用于一应用场景的基本原理图。如图8所示,在本应用场景中,对多台网关设备的负载进行动态调度来达到绿色节能的目的。设想将放置于同一站点或邻近站点的多台网关设备301、302、303、304成POOL30(池),并将用户所需的网络流量集中到一台或者多台网关设备(如网关设备301)上,令其他的网关设备303、304进入节能模式,从而达到节能目的。因此,本发明应用于该应用场景下的实现方式可具体称之为POOL内的负载分担。Please refer to FIG. 9 first, where FIG. 9 is a basic schematic diagram of the present invention applied to an application scenario. As shown in FIG. 8 , in this application scenario, loads of multiple gateway devices are dynamically scheduled to achieve the goal of green energy saving. It is assumed that multiple gateway devices 301, 302, 303, and 304 placed at the same site or adjacent sites are formed into a POOL30 (pool), and the network traffic required by users is concentrated on one or more gateway devices (such as gateway device 301) In order to make other gateway devices 303 and 304 enter the energy-saving mode, so as to achieve the purpose of energy saving. Therefore, the implementation manner of the present invention applied in this application scenario can be specifically referred to as load sharing in the POOL.

并请参见图10,图10为POOL与现有设备组成的网络系统的系统结构示意图,如图10所示,POOL30包括网关设备302、网关设备303、网关设备304等多个网关设备。用户设备通过一台或多台会聚交换机(LAN Switch)315接入(如果是多台会聚交换机的话,在多台会聚交换机之间要有全互联的链路),会聚交换机315下接多个数字用户环线接入设备(DSLAM)316、317、318,每个DSLAM接入多个用户设备(UPE:Underlayer Personal equipment)。由网关设备302、网关设备303、网关设备304的网络侧都接入到IP(Internet Protocol,网络之间互连协议)网络,通常而言为接入到一台核心路由器(Core Router)。Please also refer to FIG. 10 . FIG. 10 is a schematic diagram of the system structure of a network system composed of POOL and existing equipment. The user equipment is accessed through one or more convergence switches (LAN Switch) 315 (if there are multiple convergence switches, there must be a fully interconnected link between the multiple convergence switches), and the convergence switch 315 is connected to a plurality of digital User loop access equipment (DSLAM) 316, 317, 318, each DSLAM accesses multiple user equipment (UPE: Underlayer Personal equipment). The network side of the gateway device 302, the gateway device 303, and the gateway device 304 are all connected to the IP (Internet Protocol, interconnection protocol between networks) network, usually connected to a core router (Core Router).

获取每个网关设备上的与节能相关的信息,当与节能相关的信息示出POOL30内的负载满足如第二、第三实施例所揭示的第一预设条件时,如在夜间用户数量降低,根据以上第一、第二以及第三实施例所揭示的公式(1)来确定需进入节能模式的网络装置的数量,进一步地,可根据第三实施例所揭示的方式在网关设备之间进行负载迁移,并将需进入节能模式的网络装置置为节能模式。Obtain information related to energy saving on each gateway device. When the information related to energy saving shows that the load in POOL30 meets the first preset condition disclosed in the second and third embodiments, for example, the number of users decreases at night , according to the formula (1) disclosed in the above first, second and third embodiments to determine the number of network devices that need to enter the energy-saving mode, further, according to the method disclosed in the third embodiment between gateway devices Perform load migration, and set the network devices that need to enter the energy-saving mode to the energy-saving mode.

以下将进一步通过图11介绍本发明应用于另一应用场景的基本原理图。其中图11为本发明应用于另一应用场景的基本原理图,如图11所示,BNG1、BNG2、BNG3、BNG4分别表示在POOL内的4个不同的网关设备,其中,BNG1、BNG2、BNG3、BNG4同时开始计时,以确定时间基准,保持同步时间,并且,各个网关设备相互交换节能信息,并根据节能信息计算负载,以判断是否要进行负载迁移,在图11中,以BNG4满足负载迁移条件为例进行说明,BNG4判断到自身满足负载迁移条件,则指定负载迁移策略,向BNG2、BNG3、BNG4进行负载迁移,并在负载迁移完毕后进入节能状态。The basic principle diagram of the present invention applied to another application scenario will be further introduced below through FIG. 11 . Among them, Fig. 11 is a basic schematic diagram of the present invention applied to another application scenario. As shown in Fig. 11, BNG1, BNG2, BNG3, and BNG4 respectively represent 4 different gateway devices in the POOL, wherein, BNG1, BNG2, and BNG3 , BNG4 starts timing at the same time to determine the time reference and keep synchronous time, and each gateway device exchanges energy-saving information with each other, and calculates the load according to the energy-saving information to judge whether to perform load migration. In Figure 11, BNG4 meets the requirements of load migration. Conditions are taken as an example. BNG4 judges that it meets the load migration conditions, then specifies a load migration strategy, performs load migration to BNG2, BNG3, and BNG4, and enters the energy-saving state after the load migration is completed.

因此,在该应用场景中,由于BNG4进入节能状态,故在执行本发明实施例的方法之后POOL内正在工作的网关设备从4个变为3个,从而有效降低了能耗。Therefore, in this application scenario, since the BNG4 enters the energy-saving state, the number of gateway devices working in the POOL changes from 4 to 3 after the method of the embodiment of the present invention is executed, thereby effectively reducing energy consumption.

以上所述的设备级的节能方案利用网关设备之间传送各自的当前负载情况,每个网关设备通过分布式算法计算出需要迁移的负载量,解决了运营商对于多对多节能场景的需求,另外,分布式算法降低了通信开销,且支持多种唤醒方法,因此具有非常广泛的实用前景。The device-level energy-saving solution described above uses gateway devices to transmit their current load conditions, and each gateway device calculates the amount of load that needs to be migrated through a distributed algorithm, which solves the operator's needs for many-to-many energy-saving scenarios. In addition, the distributed algorithm reduces the communication overhead and supports multiple wake-up methods, so it has very broad practical prospects.
