Resilience and Fast Reroute in Computer Networks: Tools and Techniques to Optimize Network Performance
Published by Pearson
Tools and Techniques to Optimize Network Performance
From an application’s perspective, convergence events in a routing protocol show up as jitter followed by changed delay. Further, link and node failures in a network with high speed links can drop large amounts of traffic, impacting application performance. To resolve these problems, packet switched networks are designed to be resilient. There are, however, many different kinds of solutions, each of which is applicable to a range of problems, but none of which solves the entire set of resilience problems.
This training will provide an overview of many different solutions in the resilience space, including redundancy, BFD, graceful restart, IP based local fast reroute, MPLS based fast reroute, PIC, and others. The positive and negative aspects of each solution will be considered, including the complexity tradeoffs, how these solutions can be combined.
This training will also cover the concepts of MTBF, MTTR, and MTBM in order to provide the background for resilience.
What you’ll learn and how you can apply it
By the end of this course, you will have a solid understanding of resilience in packet switched networks using distributed control planes, including IS-IS and BGP. You will also have a good sense of where to use different tools, and which tools do, or do not, work well together.
This live event is for you because...
- You want to understand resilience in packet switched networks from a system, rather than solution-by-solution, perspective
- You want to know how each method for providing resilience in a packet switched network works in depth
- You want to understand the tradeoffs for solutions designed to provide resilience in packet switched networks
- You want to understand how solutions designed to provide resilience in packet switched networks interact with mean time between failure, mean time to repair, and other measures of network availability
Prerequisites
- Basic understanding of the principles of routing
- A basic idea of the various protocols used in an IPv4/IPv6 network
