Coyote Point Equalizer应用交付解决方案数据手册说明书

The leader in advanced featured load balancers and application deliverycontrollers built for medium and small enterprise Equalizer®DATASHEET AND PRODUCT GUIDEAchieve non-stop availability and higher application performance with Coyote Point’s award-winning Equalizer application delivery solutionsSince 1999 Coyote Point has set the standard in load balancing and application delivery solutions at price points most organizations can easily afford. From simple server load balancing to enterprise-grade global traffic management, Coyote Point can meet the needs of almost any web-based application. You can find Coyote Point solutions in companies of any size, up to the largest of Fortune 500 firms including USA Today, Motorola and Comcast.The entire Equalizer line-up of hardware and virtualization solutions meets or outperforms competitive products costing up to 3 times as much. You pay for what you need and don’t have to buy option after option to get a solution that fits your business requirements. The award-winning Equalizer product line has long been recognized for its rock-solid reliability, ease of setup and intuitive management tools. Plug in an Equalizer and it provides years of worry-free service.FEATURES❚Basic load balancing through advanced L7 traffic management❚Hardware and virtual appliance options to meet your needs❚Full support for Microsoft®, VMware® and most standard business applications❚Class-leading SSL acceleration and data compression❚Advanced Global Server Load Balancing for seamless disaster recovery❚Smart Event Automation for virtual and physical resource control❚Full IPv6 support, including 6-in-4 Tunneling to ease the transition to IPv6Reliable and robust load balancing and application deliveryAt its heart, the Equalizer is a tried-and-true load balancer that can support almost any web-based application. From simple L4 TCP and UDP to advanced L7 HTTP and HTTPS, Coyote Point can provide basic load balancing to precise content switching with L7 Match Rules (AF ). Equalizer gathers real-time information about a server’s status using ICMP Probes, TCP Probes, Active Content Verification (ACV) and Server Agents to route traffic based on easily configurable business rules. All Equalizers support persistence using either cookies or IP addresses to reliably maintain server connections for your more advanced applications.In the event that servers in a server pool are unable to satisfy a client’s request, Responders (AF ) can be assigned to L7 Match Rules to redirect users to another URL or display a custom message.High Availability for 100% application uptimeMission-critical applications need mission-ready solutions. Coyote Point’s 3-tier approach to application uptime means your applications are up and running with 5-nines reliability. The first tier is a server or application failure. If a server or application fails or becomes overloaded, Equalizer routes traffic automatically to healthy servers. For the second tier, Equalizer supports failover options to cover youshould an Equalizer go down. Finally, the third level provides routing to an alternate data center(s) should your primary data center suffer a catastrophic or planned outage (see the “Disaster recovery with Global Server Load Balancing” section for more information on multiple data center traffic management).Equalizer supports Active/Passive, Active/Active, N+1 or N+M failover configurations. Coyote Point’s Multi-Active N+M Failover (AF ) allows a cluster of active Equalizers to share the workload for a large application data center. Instead of requiring idle spares in standby mode as in other failover methods, Multi-Active N+M Failover puts all the Equalizers to work load balancing and delivering applications. If an Equalizer in the N+M cluster should fail, the others seamlessly pick up the workload until you or your team can get the failed Equalizer back online.Disaster recovery with Global Server Load BalancingEnvoy Global Server Load Balancing (GSLB) makes your network reliable and available by scalingapplications across multiple data centers for disaster recovery or to improve application response times. Administrators can set up rules that direct traffic based on site availability, data center performance and network latency.Coyote Point offers three options for Envoy. You can choose a software module for Equalizer, astandalone hardware appliance or a standalone virtual appliance. Envoy SAE, the standalone hardware or virtual appliance, offers additional features not available in the Envoy software module. It is designed to accommodate complex network structures including resolution directly to local or host-basedapplication servers. Using SNMP health checking (AF ), Envoy SAE fully integrates with ADCs from other manufacturers including F5, Citrix and A10 Networks.Advanced networking supportCoyote Point’s Equalizers use Network Address Translation (NAT), Source NAT, Outbound NAT and spoofing to effectively and efficiently route traffic between clients and servers. With support for directserver return, Multi-Gateway (AF ) and Multi-Netting (AF ), Link Aggregation (LACP), IPv6 routing, NTP and tagged VLAN support (AF ) for up to 4094 802.1Q VLANs, you get the flexibility you need as your network topology evolves without having to buy new equipment.Are you ready for the transition to IPv6? Coyote Point can make it easier with 6-in-4 Tunneling (AF ) supported on all Equalizers. Through the use of a tunnel broker, you can assign IPv6 addresses to your server clusters making them available to any client on an IPv6 network.Equalizer provides the ability to configure routing to match network topologies from the simplest to the very complex through Policy-based Routing (AF ). You can define routing behavior for each subnet, based on either destination IP address or source IP address of packets traversing Equalizer.Items followed by (AF ) are advanced features that are designed for complex application environments.If you need moreinformation on any of the items presented in this document or would like more information on load balancing and application delivery concepts, please visit or call us at (877) 367-2696.Envoy SAE with SNMP healthchecking provides global server load balancing in mixed vendor environments and supports up to 10 data centers with just one appliance.Blazing fast SSL offloading and compressionAll Coyote Point Equalizers support SSL offloading to relieve your servers from the computationalworkload of SSL/TLS session negotiation, encryption and decryption, letting them instead focus on the applications they were meant to serve. Some models come equipped with hardware-based acceleration.Not all applications were written with SSL in mind and many scale poorly when SSL is enabled. Coyote Point’s SSL offloading eliminates these problems with an easy to deploy acceleration solution. Processing is moved from your servers to Equalizer making applications significantly faster and secure without software or other intrusive changes.Coyote Point incorporates a dedicated hardware-based Gzip HTTP compression processor into some models for content-rich applications. You can compress server generated data up to 5 times before it’s delivered to a client using any modern web browser saving you bandwidth costs and improving response times to your users.Automate routine tasks to take control of your applicationsEqualizer’s Smart Control framework with Smart Control Automation (AF ) manages notifications,logging and corrections to your application environments.1 Intuitive construction of graphical or CLI-based rule sets let you configure responses to almost any condition including resource management to power up or power down IPMI-compliant servers in response to changes in demand.Virtual platform supportIf you’re looking for a comprehensive set of tools to manage your VMware environment, Coyote Point has you covered. Every Coyote Point Equalizer supports VMware load balancing using VMware’s management API to retrieve real-time virtual server availability and resource utilization from a VMware vCenter console. With Coyote Point’s Smart Control Automation (AF ) you get even deeper integration into VMware with the ability to load balance based on VM CPU and VM RAM and spin-up or spin-down VMs in response to demand.Coyote Point’s OnDemand product line-up offers virtual versions of Equalizer and Envoy SAE for loadbalancing and GSLB. You get to choose either hardware or virtual appliances for 100% flexibility to fit your needs. All our virtual products are available for a free 30-day trial to let you test them in your environment before you buy.Features to keep your applications safe and secureEqualizer intelligently controls your SSL traffic with advanced features like SSL Certificate Revocation Lists (AF ), Global Object SSL Certificate Storage (AF ), outbound HTTP to HTTPS URL rewriting and Cipher Suite Control.Guaranteed application supportFrom basic static websites to enterprise Microsoft ® Exchange installations, Coyote Point’s Equalizer can support virtually any internet-based application. Easy to follow deployment guides are available for the top Microsoft ® applications including Exchange, SharePoint ® and Outlook Web Access.Included Global Server Load Balancing (GSLB)All Equalizer load balancers and application delivery controllers include Coyote Point’s Envoy Global Server Load Balancing. Using DNS-based resolution, Envoy routes multiple data center traffic based on network latency, server health, traffic volumes or with custom business rules.1 Smart Control Automation is currently available with EQ/OS v.8.X.Smart Control Automation manages your applications 24/7 letting you focus on more important tasks.Microsoft ® recommends hardwareload balancing for Exchange installations with over 200 users. Coyote Point has been tested and approved by Microsoft ®.Flexible management and comprehensive reportingDo you prefer a command line or an intuitive graphical user interface? Either way Coyote Point provides the tools you need to easily manage your Equalizer. The context sensitive CLI provides complete control of every aspect of your Equalizer, not just a subset of functions like some other manufacturers. Even if you’re a CLI-jockey, you’ll appreciate the thought-through layout and features of our graphical user interface for most tasks from setting up server pools to running sophisticated traffic reports.Equalizer’s Role-based management(AF) gives you the flexibility to establish multiple users and groups allowing it to be managed by one or more data center personnel. As the administrator, you can assign read, write, create and delete permissions to individual users or groups to give as little or as much control over your Equalizer to fit the needs of your organization.Equalizer GUI Welcome ScreenSample of a TCP Cluster Configuration Summary ScreenEqualizer Products/PlatformsEqualizer load balancing and application delivery products are built with the needs of small and medium enterprises in mind to offer you the performance and features you need at a value that can’t be matched.

瓶颈可能出现在服务器、存储、⽹络设备,带宽等的性能不⾜,⽽运⾏⼀旦出现故障给业务带来的影响范围是巨⼤的,服务器可能出现的问题表现为如下⼏点:⾼可⽤问题关健性应⽤要求7*24稳定运⾏不被中断,⾼可⽤性问题被放在⾸要位置。

利⽤“不平衡”现象数据的⼤集中使得服务器的访问压⼒⽇益增⼤,服务器性能往往会成为⼀个系统的瓶颈,随着性能问题的产⽣,单点故障的发⽣也将⽐较频繁,为了解决这些问题,传统的⽅式多为采取更换更好的服务器并且采⽤双机备份系统提供服务的⽅式,这样必然存在⼀半的资源浪费的情况,⽽在压⼒不断上升的情况下,这种动作讲不断的重复,不但服务器的利⽤率不平衡,⽽且持续引起投资的浪费。

“峰值”问题服务器的处理多存在“波峰”和“波⾕”的变化。

⽽且“波峰”时,业务量⼤⼩的变化⼜不规律,这就使服务器不得不⾯对“峰值堵塞”问题。

原有解决⽅法为增加服务器或主机数量,提⾼处理能⼒。

但仍存在性能不平衡问题,且这样做,投资成本⼤。

多⽶诺”现象单台服务器的设置,不可避免会出现“单点故障”,需要进⾏服务器“容错”。

A10产品及电信行业应用分析

A10产品及电信行业应用分析

A10公司AX产品及行业应用分析Yulin Wang1第一部分产品概述随着Internet的快速增长以及基于Web的应用以前所未有的速度增长,关键业务的性能,安全和可用性对企业现在和未来提高竞争力是至关重要的。

A10网络公司的AX系列高级流量管理设备就是为适应Web和三网融合业务(数据,语音,视频)的增长需求而设计的。

AX 提供智能的的4-7层应用处理能力,在极具竞争力的价格基础上,AX具有业界领先的性能和可扩展性来满足关键业务的需求,结果就是带来业界最好的性价比解决方案。

A10公司的AX系列产品具有如下特点:1.功能丰富.(无需购买额外License)2.超高的性能,超高性价比3.冗余硬件4.高性能安全防护5.易于使用和管理2第二部分市场分析服务器负载均衡设备从技术上来讲是跟行业无关的,基本上凡是通过服务器提供应用访问和各种服务的企业单位在服务器遇到瓶颈访问速度变得缓慢的时候,都可以考虑对服务器做负载均衡,以提升性能和服务质量。

但是不同行业对功能的要求会有所偏重,对性能要求也有差别,所以需要对AX产品针对不同行业做一下分析。

2.1 运营商市场分析中国运营商包括电信、移动、网通、联通和铁通等。

各自具体的业务有所不同,但对产品规格的要求是具有相似性的。

基本上需要满足以下几点:1.功能上需要能够满足相关业务系统的要求。

2.性能上需要能够满足电信级访问量的需求。

3.硬件上需要冗余性,以满足运营商业务的不间断运行。

4.设备需要具有抵抗DDOS攻击的能力,以保护后面的关键服务器不受攻击。

5.管理和维护需要简单,直观。

运营商市场对负载均衡和应用优化产品具有很大的需求量。

部分需要负载均衡解决方案的业务系统介绍如下:1.移动/联通的彩铃彩信系统:由于手机用户非常多,所以对彩铃彩信系统的访问量是比较大的,因此单台彩铃彩信服务器的性能必然无法满足访问需求,需要使用负载均衡设备将用户请求分发到多台服务器,以提升总体服务能力。

A10-链路负载均衡(LLB)解决方案-YL

A10 链路负载均衡解决方案1. 概述由于国内各运营商之间的互联互通一直存在很大的问题,采用运营商自身单条互联网出口,在为用户提供IDC主机托管服务和大客户专线接入服务时,会遇到用户抱怨访问速度差的问题。

同时,单条链路本身存在单点故障问题。

因此,通过在多个数据中心分别拉不同运营商的线路或者同一数据中心或公司网络出口采用多条互联网链路并使用专门的负载均衡设备智能选择最佳链路成为提高服务水平和用户满意度的一种有效方式,我们把多数据中心负载均衡和多链路负载均衡统称为全局负载均衡或者广域网负载均衡。

2. 需求描述对于全局和链路负载均衡,需要解决两种流量类型的负载均衡以及容灾问题:入向流量(Inbound Traffic):从Internet上的客户端发起,到数据中心内部的应用服务的流量。

如:Internet上用户访问企业Web网站。

对于入向流量,需要根据当前网络延时、就近性等因素,来判断哪一条链路可以对外部用户提供最佳的访问服务。

出向流量(Outbound Traffic):从内部网络发起的,对Internet上应用资源的访问。

如:内部局域网用户访问Internet上Web网站应用。

对于出向流量,需要根据当前链路的就近行、负载情况、和应用服务的重要性等选择最佳的链路。

容灾:多数据中心除了可以提高服务质量之外,另外一个重要的目的就是容灾,当一个数据中心出现故障,将所有用户访问由灾备数据中心来处理。

A10 Networks教育行业应用交付解决方案
随着学生电脑和远程教育的普及,基于网络环境的学习已成为一种新的学习理念,改变、丰富高校园区内师生学习生活的同时,也对校园网络的稳定、安全、可靠提出了新的要求。

随着高校信息化应用在教学、科研、办公、生活等方面不断深入,用户对于校园网平台的依赖性越来越强,大规模并发访问带来网络各个核心部分业务量上升,访问量和数据流量增长,相应的处理能力和计算强度也迅速增大,从而引起核心网络设备过载,网络瓶颈和网络拥塞等问题,出现网络不稳定、网速慢、安全能力差等异常情况。

校园网具有规模大、功能多、结构复杂的特点,一般校园网都要承载上万人的互联网接入、近百个应用系统的同时运行,因此保障互联网接入用户拥有良好的上网体验、重要应用系统稳定高效是十分重要的,同时也面临诸多挑战。

需求分析
随校园网络承载的应用越来越多,后台服务器和网络的访问压力也逐渐增长。

目前校园网主要提供以下几类网络服务,均面临这不同的挑战。

互联网接入服务:校园网一般需要为全校师生提供互联网接入服务,方便全校师生通过互联网来更好的完成工作和学习。

校园网内所有用户访问互联网的数据流量,及互联网用户访问学校网络资源的数据流量都流经出口网关,而校园网基本都采用多运营商多链路接入,因此出口网关能否将流量合理的分配到各个链路是校园网用户访问体验的关键。

发布信息的平台:校园网不仅对校内师生提供服务,还需对互联网用户提供服务,通过门户网站、BBS、邮件系统等与外界进行信息发布和信息交互。

高校门户网站、招生网都是外界了解高校的重要途径,也是学校对外发布信息的主要媒介,在高考前后,广大考生和家长对网站访问量突增,网站能否保持稳定、高速的对外服务非常重要。

校园管理信息系统:校园网运行各类与教学、科研、管理相关的管理信息系统,如办公系统、人事管理系统、教学管理系统、学生管理系统、科研管理系统、财务管理系统、图书馆管理系统、后勤管理系统等。

由于校园网中的应用系统要面向全校师生同时提供服务,访问时间又相对集中,因此存在瞬间集中访问的情况,这会给后端服务器系统造成很大的访问压力,导致访问迟缓甚至宕机停止服务。

远程教育与多媒体教学系统:随着互联网的普及,高校越来越重视远程教育平台和多媒体教学平台的建设,使知识以文字、语音、视频的形式通过互联网方便的传播,让渴望知识的人随时随地通过网络学习。

这类应用系统中提供的语音、视频等服务,使得单用户访问流量大,当同时面向全校师生或互联网用户提供服务时,存在单台服务器性能不足的问题,可能出现访问缓慢甚至宕机的现象。

解决方案描述
1、链路负载均衡是校园网出口网关的最佳选择
A10 Networks ADC作为出口网关设备,具备路由及NAT功能、链路负载均衡、安全防护、IPv6迁移能功能,校园师生可通过最快的链路访问到网络资源,并保障各链路流量分布均衡,既能充分利用带宽资源又能实现网络的最快访问。

2、打造稳定高速的对外信息发布平台
为保证高校对外信息发布平台的稳定、高效,A10 Networks ADC可启用智能DNS功能,使门户网站等信息发布平台的域名同时与多条链路的IP对应,对外服务站点通过多条链路同时提供服务,ADC根据访问用户使用的运营商、所处的地理位置等信息,选择最快的链路连接学校站点。

在任何链路出现故障时,第一时间感知,并将访问转向可用的链路。

3、实现校园网各信息系统的应用可达、应用加速、应用安全
校园内有多个典型的信息系统是面向全校师生开放的,例如电子选课系统、入学管理系统、就业网、统一认证系统等,学生的作息时间统一、规律,因此对这些信息系统的访问时间也相对集中。

为解决这个问题,A10 Networks ADC解决方案采用丰富的负载均衡算法,可将全部可用的服务器资源虚拟为一台服务器,向师生提供服务,并根据真实服务器的性能和健康状况,选择最佳的服务器响应师生的应用请求。

对于统一认证系统这类采用SSL加密方式进行数据传输的系统,A10 Networks ADC利用内置的高性能SSL 加速芯片,加速处理SSL加密和密钥交换过程,后台服务器可改为HTTP明文传输,大大缓解服务器的CPU压力。

由于SSL具有卸载能力,ADC可对加密流量进行监测,从而确保了正确适当的流量分配,还能简化对证书的管理,进一步提高统一认证系统的访问速度。

4、提升远程教育与多媒体教学资源的访问体验
VOD点播系统:很多高校通过VOD点播系统提供在线多媒体教学,它是突破时间、空间限制的网络教学系统,但存在单机用户访问流量大的特点。

BlackBoard在线教学管理系统:是以课程为中心集成网络“教”“学”的环境,学习者之间、教师和学生之间可方便进行交流的教学平台。

每当临近考试,BB系统开始繁忙,满足全校师生的访问需求是一个很大的挑战。

A10 Networks ADC支持HTTP压缩技术,可对指定的内容进行压缩,大幅节省内容传送时所需要的带宽。

且支持TCP连接复用技术和内容缓存功能,大大减轻了服务器的负载并节省了后端的网络带宽,最大化的提高访问这些资源的速度。
