  3. 3. Rethink Server Load Balancer Testing Introduction Today’s network is under higher demand than ever before, each day handling ever growing and more complex business and Web applications. A single server will not be able to handle the load demand required; multiple servers are needed and must be used to meet the demand. For ease of use, a single IP address or domain name must be used; however, if several servers are required, this adds complexity. Using a load balancer can ease the complexity of the network setup. With the continued development of web applications, virtualization, cloud computing and more, a load balancer has become an integral piece of networking equipment. With the use of a load balancer, a single service can be provided from multiple servers. A load balancer runs on Layers 4 through 7 of the OSI Model, and some of the common protocols that are usually load balanced are HTTP, IRC, FTP, NNTP and DNS. When in use, a load balancer is placed in front of a server farm on the network. The load balancer listens on the needed port, and when a request comes in for the service, the load balancer will forward the request to one of the available servers. When the back-end server receives the request from the load balancer, it will respond to the load balancer. In turn, the load balancer will respond to the client that made the initial request. This makes the load balancer an invisible piece of networking equipment to the client. Load balancers are aware of the requested protocol and will forward the connection to the correct server. Since not every server will be on equal hardware or be able to handle equal loads, load balancers can be configured with an assigned weight for each server. For example, a single core server can be configured with a lower weight than a quad core server because the quad core server will be able to handle a higher offered load. This ensures that each client will receive the same experience as the next. Another added benefit of using a load balancer is it helps maintain uptime of the requested services. If one server fails or is taken down for an upgrade, the remaining servers are able to maintain and handle the load until the downed server is online again. Not all load balancers are created equal. Some have more features than others, but a set of common features does exist between them. As expected, load balancers support all TCP and UDP protocols. A form of SSL acceleration is usually available to improve the speed of encryption. Another common feature is content caching: The load balancer will store objects that are frequently used. When this object is requested, the load balancer will speed up the process by sending the object instead of asking a server for it. Other common features that load balancers support are content compression, session persistence and bandwidth management. The following Resiliency Methodology will demonstrate how to configure a load balancer and set up the BreakingPoint Storm CTM. This Resiliency Methodology contains five different measurements and each are given a brief outline below. Test 1: Layer 4 TCP This test will determine the number of TCP connections per second that the load balancer is able to handle. Also, the TCP setup time will be analyzed to determine how a greater number of TCP connections per second affects the time it takes to establish the TCP connection. This test is also a baseline measurement for tests 2-5. Test 2: HTTP This test will determine the number of HTTP connections per second the load balancer is able to handle. Also, the BreakingPoint Storm CTM will be configured to serve out five different sized HTTP pages. The overall bandwidth that the load balancer is able to support will be determined. Test 3: HTTPS This is the same test as the HTTP , except encryption will be used. Normally, the HTTPS connection is made with the load balancer, and the connection between the load balancer and the server is not encrypted, taking away the overhead of encryption.www.breakingpoint.com© 2005 - 2010.

  4. 4. Rethink Server Load Balancer Testing Test 4: HTTP Caching As load balancers are able to locally cache objects, the BreakingPoint Storm CTM will be configured to send out dynamic pages and image files. The TCP connection setup time will be analyzed to make sure the load balancer is locally caching the needed files. Test 5: Dual Traffic HTTP and IMAP Load balancers are able to handle multiple protocols at a time. The BreakingPoint Storm CTM will be configured to use both HTTP and IMAP protocols. This helps determine the load balancer’s ability to handle multiple protocols while being stressed. Data rates and TCP setup times are a couple of the results analyzed at the end of the test. Test 6: Fuzzer This test is an add-on test to the previous ones. This test will ensure that the load balancer is able to handle malformed packets or errors within the packet. Results will be examined to determine the load balancer’s ability.www.breakingpoint.com© 2005 - 2010. BreakingPoint Systems, Inc. All rights reserved.

  5. 5. Rethink Server Load Balancer Testing Layer 4 Top TC RFC: • RFC 793 – Transmission Control Protocol Overview: A basic Layer 4 TCP measurement will be performed. The load balancer should be configured with an open port of 80, as this is the port that will be used during the test. The load balancer also should be configured with a range of IP Addresses that amounts to about 5% of the total supported back-end servers to act as the end points for the TCP measurement. The BreakingPoint Storm CTM will act as both the clients and the servers during the measurement. The BreakingPoint Storm CTM will be configured to use the Session Sender test component to generate and receive the TCP requests. Objective: Determine the maximum number of TCP connections per second a load balancer is able to handle before dropping requests. Setup:www.breakingpoint.com© 2005 - 2010. BreakingPoint Systems, Inc.

This test will use several images and several Web pages to help determine a load balancer’s ability to cache the required items. Objective: Determine the ability of a load balancer to cache static data and relieve stress from Web servers. Setup: This test will require the use of several images.

The BreakingPoint Storm CTM will be configured with two test components. The first test component will use the HTTP protocol and the second one will use IMAP. The BreakingPoint Storm CTM will act as both the client and server for each protocol. Each test component will be configured to step the connection rate at a different interval. The results will be viewed to determine how the load balancer is able to handle multiple traffic streams from multiple protocols.
