Proekt Seti Metro Ethernet Diplom

Metro Ethernet is an Ethernet transport network (shown in Figure 1) that provides point-to-point or multipoint connectivity services over a metropolitan area network (MAN). Ethernet originated as a LAN technology, and became a replacement for low-speed WAN technologies. Responsible for strategic and technical high level support of the Openserve Metro Ethernet network. Provide specialized assistance with regards to the core network operations, service operations, planned project roll out, the NNOC (Tier 0 & 1), technology & services integration, and training.

A metropolitan-area Ethernet system A metropolitan-area Ethernet, Ethernet MAN, or metro Ethernet network is a (MAN) that is based on. It is commonly used to connect subscribers to a larger service network or the.

Businesses can also use metropolitan-area to connect their own offices to each other. An Ethernet interface is much cheaper than a (SONET/SDH) or (PDH) interface of the same bandwidth. Another distinct advantage of an Ethernet-based access network is that it can be easily connected to the customer network, due to the prevalent use of Ethernet in corporate and, more recently, residential networks. A typical network is a collection of and connected through. The could be a, (star), or full or partial. The network will also have a hierarchy: core, distribution (aggregation), and access. Programmu rascheta sosudov passat.

The core in most cases is an existing / backbone but may migrate to newer forms of Ethernet transport in the form of 10Gbit/s, speeds or even possibly 400Gbit/s to network in the future. Ethernet on the MAN can be used as pure Ethernet,, Ethernet over (MPLS), or Ethernet over. Pure Ethernet-based deployments are cheaper but less reliable and scalable and thus are usually limited to small scale or experimental deployments. The sims 3 expansions download completo gratis em portugues para pc windows 7. SDH-based deployments are useful when there is an existing SDH infrastructure already in place, its main shortcoming being the loss of flexibility in bandwidth management due to the rigid hierarchy imposed by the SDH network.

MPLS-based deployments are costly but highly reliable and scalable and are typically used by large service providers. Contents • • • • • • • • Metropolitan area networks [ ] Familiar network domains are likely to exist regardless of the transport technology chosen to implement: Access, aggregation/distribution, and core. • Access devices normally exist at a customer's premises, unit, or wireless base station. This is the network that connects customer equipment, and may include (ONT), a residential gateway, or office router.

• Aggregation occurs on a distribution network such as an segment. Often, microwave or technologies are employed, but some of them using point-to-point Ethernet over 'home-run'.

This part of the network includes nodes such as Multi Tenanted Unit switches, in an or cabinet, equipment, or provider bridges. • A MAN may include the transport technologies MPLS, and T-MPLS, each with its own resiliency and management techniques. • A core network often uses IP-MPLS to connect different MANs together. Much of the functionality of Ethernet MANs such as virtual private lines or is implemented by the use of Ethernet tags that allow differentiation of each part of the network. Logical differentiation of the physical network helps to identify the rights that the traffic has and to ease the management of hosts' access rights with respect to other users and networks. MPLS-based Ethernet MANs [ ] A (MPLS) metro Ethernet network uses MPLS in the service provider's network. The subscriber will get an Ethernet interface on copper (for example, ) or fiber (such as ).
