IntroductionToday’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.

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.

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.

• Maximum TCP Open Rate (full open of clients, do not close client connections)

• Maximum TCP with Opening and Closing clients at same time.

• Throughput tests with varying number of clients.

• Increased number of supported back-end servers to 10%, 25%, 50%, 75% and 100%.

HTTP Load Balancer Test

RFC:• RFC 1945 – Hypertext Transfer Protocol – HTTP/1.0

• RFC 2616 – Hypertext Transfer Protocol – HTTP/1.1

Overview:

The BreakingPoint Storm CTM will simulate the HTTP protocol. The BreakingPoint Storm CTM will simulate both the client and the server.

The server will respond with different page sizes to help mimic a more realistic Web browsing session. The load balancer will distribute the

connections to the simulated Web servers, and we can determine the number of connections per second possible with the configuration of

the load balancer.

Objective:

Determine the number of HTTP connections per second possible.

HTTPS/SSL

RFC:• RFC 2818 – HTTP Over TLS

Overview:

Load balancers can use SSL to help relieve some of the processing required of a Web server to handle SSL. The client makes an SSL request

to the load balancer, and the load balancer makes a normal unencrypted HTTP request to the Web server. The BreakingPoint Storm CTM will

be configured with two test components. One will be the SSL Clients, and the other will be a Web server. This test will help determine the

load balancer’s ability to offload SSL from the Web server.

Objective:

Determine the ability of the load balancer to handle SSL connections and the rate of SSL Connections per second it can handle.

HTTP Caching

Overview:

To help relieve some of the stress on Web servers, load balancers are able to cache static items. The test will be configured with two test

components. One will be configured with static data, and the second will be configured with dynamic data. 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. Before starting with the test configuration, either find or create images of

the following sizes:

• 4k

• 8k

• 16k

• 24k

• 188k

• 476k

• 720k

Dual Traffic HTTP and IMAP

• RFC 3501 – Internet Massage Access Protocol – Version 4rev1

Overview:

The load balancer should be configured with both port 80 (default HTTP) and 143 (default IMAP) open. 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.

Objective:

Determine the load balancer’s ability to handle multiple protocols and process the incoming data at a reasonable rate.

Load Balancer Configuration

The configuration used in these tests is not very complex. Three different clusters were configured, one for HTTP, one for Mail, and finally

one for SSL. Each cluster contains 6 servers.

The Mail Cluster has an external IP address of 10.0.255.20 and uses only port 143.

Each of the 6 mail servers has a unique IP Address and uses port 143.

The only difference with the HTTP Cluster is an external IP address of 10.0.255.10 and uses port 80. Also, the only difference with the SSL

Cluster is an external IP address of 10.0.255.30 and the use of port 443. Also, the SSL Cluster requires a Certificate to use.
