EXECUTIVE SUMMARY
As time progresses, technology often follows. In the world of networking, the need for infrastructures to implement and maintain current technologies is necessary, in order to remain compatible with mainstream networking standards. Currently, LAN technology is being implemented to connect all the end systems within each building and WAN technology to connect the buildings to the headquarters site. This proposal is designed to present upgrade solutions to the existing WAN and LAN topologies, introduce the IPv6 protocol as a remedy to IPv4 address exhaustion, and implement Etherchannel as means of providing fault-tolerance and high-speed links between switches, routers, and servers.
Explanation / Answer
IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4.
The two protocols are not designed to be interoperable, complicating the transition to IPv6. However, several IPv6 transition mechanisms have been devised to permit communication between IPv4 and IPv6 hosts.
IPv6 provides other technical benefits in addition to a larger addressing space. In particular, it permits hierarchical address allocation methods that facilitate route aggregation across the Internet, and thus limit the expansion of routing tables. The use of multicast addressing is expanded and simplified, and provides additional optimization for the delivery of services. Device mobility, security, and configuration aspects have been considered in the design of the protocol.
EtherChannel is a port link aggregation technology developed by Cisco, which provides fault-tolerant high-speed links between Switches, Routers, and Servers. EtherChannel technology allows multiple physical Ethernet links (Fast Ethernet or Gigabit Ethernet) to combine into one logical channel.
EtherChannel technology allows grouping of several physical Ethernet links (Fast Ethernet, Gigabit Ethernet, or 10 Gigabit Ethernet) to create one logical Ethernet link for the purpose of providing fault-tolerance and high-speed links between switches, routers and servers.
EtherChannel technology can be used to increase the bandwidth between two devices that support EtherChannel technology and EtherChannel technology provides automatic recovery for the loss of a link by redistributing the load across the remaining links. EtherChannel technology allows automatic redirection of network traffic from the failed link to the remaining links in EtherChannel.
An EtherChannel consists of individual Fast Ethernet or Gigabit Ethernet or 10-Gigabit links bundled into a single logical link. The EtherChannel provides full-duplex bandwidth up to 800 Mbps (Fast EtherChannel FEC) or 8 Gbps (Gigabit EtherChannel) or 10 Gbps (10-Gigabit Etherchannel 10 GEC) between Switches, Routers and Servers.
The main advantages of EtherChannel technology is that it allows load sharing of traffic among the links in the channel as well as redundancy in the event that one or more links in the EtherChannel fail.
EtherChannel is a Cisco Copyrighted term and the term which industry adopted is "Link Aggregation"
