A host can use the flow label and the traffic fields in the IPv6 header. A host uses these fields to identify those packets for which the host requests special handling by IPv6 routers.

Description
Does IPv6
have built-in security? Does IPv6 support Quality of Service (QoS)?
IPv6 Packet Security
Unlike
IPv4, IPsec security is mandated in the IPv6 protocol specification, allowing
IPv6 packet authentication and/or payload encryption via the Extension Headers.
However, IPsec is not automatically implemented, it must be configured and used
with a security key exchange.
A host can use the flow label and the traffic fields in the IPv6
header. A host uses these fields to identify those packets for which the host
requests special handling by IPv6 routers. For example, the host can request
non-default quality of service or real-time service. This important capability
enables the support of applications that require some degree of consistent
throughput, delay, or jitter. These types of applications are known as multi
media or real-time applications.
You have been tasked with
reconfiguring the network for your company, which has grown considerably over
the past year. You have used only static routing in the past, but you do not
wish to spend the administrative time required to maintain the routing tables
now that the network has grown. You have recently experienced numerous
inaccuracies in the routing table caused by entries you made when in a hurry.
Criteria for the
reconfiguration includes the following:
- You would like to automate
the entry and updating of routing information, but you are concerned about
excessive memory and processor utilization if you implement dynamic
routing protocols.
- You also wish to minimize
the use of network bandwidth.
- You prefer that the most
efficient use of bandwidth be made so that packets will travel to their
destination over the truly shortest path, rather than just the path with
the lowest number of hops.
- You have heard that routing
loops can be a problem and wish to avoid them. However, you are concerned
that if a link goes down, there should be redundancy so that traffic will
go through.
In 2-4 page summary,
complete the following
- How can you accomplish
your objectives?
- What routing protocols and
protocol features will you use to do so?
- Provide detailed examples.
