How Metro Ethernet Works And How Do ISP's Employ Its Technology?
An MPLS network covers a wide location span as big as a city area. It uses a group of Layer two and layer three switches and routers using fiber optics connections. This connection is connected with the use of fiber optics to extend the range capabilities of the network compared to local Ethernet connection in the office or home networks.
It is usually used for home consumers and business consumers to connect to a larger system of networks or the Internet. Using Optic cable, both Metro and local Ethernet have same topology such as ring, hub-and-spoke and partial and full mesh but putting Metro Ethernet in a larger scale. 70 km on a single mode with 1555nm core is the maximum range of a Fiber optics.
It is divided into layers for easy manageability: the Core network which relies on the speed on transmission because it carry bigger bandwidth, Distribution which handles the proper distribution and ensures that signal are accurately routed, and the Access Layer which is the terminating network next to the client side. It is scalable to newest available technology the 10G and the 100G speeds.
MAN Ethernet can be set up as either Ethernet only or over DWDM, SDH or as Ethernet over MPLS. Pure Ethernet uses Ethernet technology on all its segments. Dense Wavelength Division Multiplexing (DMDM) which replaces Time Division Multiplexing (TDM) is a pure packet transport. Ethernet over SDH makes use of existing SDH equipments to send Ethernet connections to already existing infrastructures. Ethernet over MPLS carries Ethernet signal by using Multiprotocol Labeling Switching (MPLS) network technology.
With the already existing infrastructures usage, Metro Ethernet can sustain and maintain a lower cost of implementation. Purchasing High Bandwidth capable connection is now made more affordable and cheaper for consumers. With already existing equipments and infrastructures, Carrier Ethernet will have a lower cost implementation. Being well-deployed even in the customer network, it can be customized and configured easily. Because Ethernet is being used even in their Local Area Network and Service Provider, it is easily connected to the end networks and the Core network.
With this technology, it does not need any additional equipment for converting signals from one form to another. Because of this speed has increased and cost has been trimmed down.
Upgrading is one of the benefits in implementing metro ethernet services because it is easily setup, upgrading or replacing hardware is fairly simple, you just disconnect the Ethernet cabling and replace the hardware. ensure 99% uptime of the network ensure a 99% uptime network.
If business requires for an upgrade, Ethernet is scalable, replacing the core layer equipment can increase the speed exponentially and the latest Ethernet technology is already deploying up to 10GBps. Since Ethernet is being used and VLANS are allowed to be set on the Ethernet, the best efficiency of Metro Ethernet VPN can be easily implemented for these structures.
For all this versatility, metro ethernet is quite an attractive option.
sharing an internet connection between computers on an ethernet network?
to facilitate sharing an internet connection between computers on an ethernet network, you should install a router.
True or false?
True, you can simply use a hub or switch, but both have problems.
A hub will send incoming signals to all computers on the network, usually resulting in network collisions. A switch will send signals to the computer that requested it only, but is inherently insecure. A router provides accurate addressing and security.
Aztech enters smart TV market (cnet)
Its new PlayXtreme Internet TV hub offers Web browsing, apps and a media
playback function for your old TVs. (Credit: Aztech)Turn your old TVs "smart"
with the latest Aztech PlayXtreme Internet TV hub powered by Android 2.3. The
petite 120 x 120 x 30mm box features a Web browser with Flash support,
preinstalled apps and a media player function. The PlayXtreme will be launched
during SITEX for S$199, followed by other countries in Asia such as Hong Kong
and Malaysia from end-December.Users can access a variety of online content
and games ranging from CNBC News to Facebook and Angry Birds. To make text
entry and app navigation a breeze, Aztech has bundled a remote with a full
QWERTY keyboard and Wiimote-like motion-sensing capabilities. Multimedia
feature-wise, the PlayXtreme Internet TV Hub is compatible with most popular
file formats such as 1080p MKV videos. There're two USB ports and an SDHC card
slot to connect external USB storage devices, as well as an Ethernet jack and
UPnP support for network streaming from PCs.While Aztech is a latecomer in the
media player/smart TV market, the company is confident that it will be able to
grow its product portfolio ...
