Summary

In this chapter, you learned about four technologies that can be useful in your networks; the following topics were presented:

• IP multicast, which enables data to be sent from a source to a group in the most efficient way. The data travels from the source as one stream as far as it can in the network. Devices only replicate the data if they need to send it out on multiple interfaces to reach all members of the destination group.

• Increasing network availability, based on the business objectives, by using redundancy and having the appropriate processes and procedures in place.

• Storage networking, which allows data to be accessed over the network instead of being embedded in or directly attached to servers.

• IPv6, the next generation of IP, which was created to overcome the limitations of IPv4.
