Pbb And Mpls Complementary Technologies For Next Generation Carrier Ethernet Transport

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

In order to provide a network infrastructure to over 600 users on the TaxiPixi network infrastructure, Fiber optic cabling system will be implemented in the LAN design because it is one of the best transmission media options.

So therefore, based off the information provided, I would recommend a packet switched architecture, or more specifically a Frame relay with a CIR 45 Mbps WAN service. Frame Relay is packet switched data link layer protocol that handles multiple virtual circuits using High-Level Data Link Control (HDLC) encapsulation between connected devices. (Cisco, 2005) In many cases, Frame Relay is more efficient than X.25 and generally less expensive than ATM. Also the data provided does not suggest that MegaCorp specifically has needs for the extensive QoS information that ATM provides that would enable the setting of very precise priorities among different types of transmissions such as high priority for voice and video and lower priority for email. If the company were a consulting firm with a high propensity for needs on bandwidth because of video conferencing or high bandwidth requiring applications then perhaps ATM architecture with a T1 or T3 WAN service might be more suitable. Even though MegaCorp is a large manufacturing firm recommending Ethernet services might prove to be too expensive of a proposal as well and thus causing us to lose the project. The cost associated to having each factory connected by fiber optic cables to the provider’s city wide MAN backbone plus the cost of the Ethernet switch might not be justified by the company’s bandwidth needs.

I have described my observations of the rate of change in Ethernet data transfer capacity.

contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.

The Newton Ad Agency will be using a Wide Area Network (WAN) network since its connectivity needs to span over a number of locations. The WAN connection should be able to provide the likeness of a Local Area Network (LAN) connection in regards to performance for the branch offices, support several applications, and have a high performance. The headquarters and two branch offices will use a Virtual Private Network (VPN) connection to the internet and require at least two routers, security gateways, and Ethernet switches at all three locations. All of these devices will be connected with full mesh WAN connections that tie to the Austin headquarters with the utilization of both Internet and private WAN connectivity. This type of connection will allow for Voice over Internet Protocol (VoIP) and video services to be supported and can accommodate both wired and wireless LAN infrastructures. The network will be implemented with the

In contrast, Cisco Layer 2 Resiliency advantages are claimed to offer rapid failover without service disruption. The layer 2 is designed to streamline change management and service turn-up without WAN disruption with fewer errors. It offers a high availability through real-time recovery and resiliency at the network, device and design levels. Cisco Layer 2 Resiliency offers increased system redundancy at the platform level, network security through access layer defense, identity-based trust, pervasive security and management as well as providing device posture assessments. Operational efficiency is achieved through automated configuration, proactive diagnostics and simplified troubleshooting. This is designed to provide predictable application performance to support converged applications as well as support IP multicast for new applications.

While Internet Service Providers (ISPs) want to create a tiered approach, saving the faster speeds for their premium customers while charging “heavy band-with users” in order to generate revenue, enhance their systems and build more robust, more advanced networks,

A metropolitan-area Ethernet is a metropolitan area network (MAN) that is based on Ethernet standards. It is commonly used to connect subscribers to a larger service network or the Internet. Businesses can also use metropolitan-area Ethernet to connect their own offices to each other.

Networking is not new; it has been around for a long time. The way networking is done changes all the time; let’s look briefly at the past and how networking has changed over the years.

The Modern Mouldings current wired infrastructure will be appraised based on the following qualities. Speed, Topology, Scalability, Cost, Reliability and Availability.

In an ever-evolving world , people come up with new idea each day , some of them are in the field of robotics , some in computer security and some are in computer networks. Well the Network industry has risen up and been on a peak ever since 2008 , with new technologies coming by every year , but they had to slow the roll down of such innovations in the field just to make the previous technology have a good life span and make devices adapt to a certain technology for a certain time .
