Load Balancing with CISCO Routers #114

Load Balancing with CISCO Routers:
What is load balancing?
Simply, distributing the traffic across multiple different paths/destinations. The definition is context-specific as well. For example, if you provide a web-service, you can use multiple servers to provide the service. Then for you, load balancing can be simply distributing the incoming service request across these servers (than just to one server). For the network operators (say the internet operators), load balancing can be distributing the network traffic across multiple paths so that some paths are not congested (traffic is even across the internet backbone).

“A definition from the online Wikipedia:
In computer networking, load balancing is a technique to distribute workload evenly across two or more computers, network links, CPUs, hard drives, or other resources, in order to get optimal resource utilization, maximize throughput, minimize response time, and avoid overload. Using multiple components with load balancing, instead of a single component, may increase reliability through redundancy. The load balancing service is usually provided by a dedicated program or hardware device (such as a multilayer switch or a DNS server).

It is commonly used to mediate internal communications in computer clusters, especially high-availability clusters. If the load is more on a server, then the secondary server takes some load while the other is still processing requests” [http://en.wikipedia.org/wiki/Load_balancing_%28computing%29]

Some resources for Load Balancing with CISCO Routers:
Before pointing you to the resources, some notes

  • If you go through an undergraduate program in Computer Science, you will know the theory behind most of the protocols as will be named in the resources. If you go through the materials for Cisco certifications, you will know the IOS commands to deal/interact with the protocols (configure the protocols in real life situations).
  • Universities may not give you an opportunity in your undergraduate program to deal with real-life routers, and play with the routing protocols. If they would (even as an extra facility not part of your courses) that could be something very useful for your career (esp. when network/telecommunications oriented) (could even make you more interested in networking/inter-networking careers).
  • However, universities may teach you writing prototype network software, network protocols, and components for network operating systems. Universities will also teach you the graph theory, queuing theory, and analysis of network protocols. These are must know to write routing/networking protocols. The people who write the network operating systems, and/or network/routing protocols are mostly from theoretical (university) backgrounds. Even if your interests are to implement routing logic in hardware, and designing and implementing routers, university education (in Comp. Eng.) will be of more help than Cisco Certification materials (knowing these materials will always be a plus)
  • (Limited Opportunities): If your intentions are to come up with new and better routing protocols, improve the efficiency of the existing protocols, and even discover new routing protocols for newer computing platforms (such as Sensor Networks, Zigbee, VOIP, and similar), you will mostly require to go through research based Masters and PhD programs in Computer Networking and related [In another word, graduate studies (in networking) focus on these (Improving existing protocols, network standards, inter-networking standards, data transfer methods, routing. Also, discovering new protocols, network standards, inter-networking standards, data transfer methods, routing, and related].
