How to calculate the edge network to change the
edge is a simplified calculation things device provides a method for real-time traffic flows and local data analysis
Things calculations allow the edge (the IoT) device generates data created closer to its processing position, rather than through the long path to transmit data to a data center or a cloud.
By computing closer to the network edge, organizations can analyze critical data almost in real time - this is the demand of many industry organizations, including manufacturing, healthcare, telecommunications and finance.
Cisco's senior director of corporate strategy innovation Helder Antunes, said: "In most cases, assuming that everything will be in the cloud, and there is a strong and stable dense pipeline between the cloud and edge devices - which is not realistic."
What exactly is calculated edge?
Edge computation is a "micro-mesh network data center, critical data may be processed or stored locally, and will push all the received data to a central repository or cloud data center, covers an area less than 100 square feet," Study The company IDC said.
It is usually used in the network in the embodiment mentioned, wherein the edge device collects data - and sometimes large amounts of data - and to send all or cloud data center for processing. Computing edge data in the local classified, so some of the data processing locally, thereby reducing the backhaul traffic to a central repository.
Typically, this is done by IoT device to transmit data to the local device to complete, the local device comprises a small-sized computing, storage and network connections. Processing the edge data, and all or part of a company is sent to a data center, a central processing facility or repository co-located or IaaS cloud.
Why edge computing is important?
Computing deployments edge in each case is the ideal choice. Is a poor connection device things, things device constantly connected to a central cloud is not efficient.
Other use cases related to the delay sensitive information processing. Reduced edge latency can be calculated, since the data need not be processed by traversing the network or cloud data center. This applies to the case millisecond delay may not be maintained, such as financial services or manufacturing.
The following is a calculated example of the edge of deployment: oil rigs in the ocean, there are thousands of sensors generating a large amount of data, most of which may not matter; may be the normal operation of the data verification system.
Once the data is sent across the network is not necessarily required, so the local edge computation and data transmission system to compile the daily report to the central data center or a cloud for long-term storage. By transmitting only the important data through the network edge computing system reduces the data traversing a network.
Another embodiment using edge computing companies to build the next generation of telecommunications 5G cellular network. Kelly Quinn IDC Research Manager Research edge computing forecast, with the telecommunications provider established in its 5G wireless networks, they will be adding more and more integrated into the tower 5G or 5G tower adjacent micro data center. Business customers can have in these micro-data center or rent space edge computing, telecommunications providers and direct access to a wider range of network gateway, the network can be connected to a public cloud IaaS providers.
Fog edge computing
with the formation of edge computing market, there is an important terms related to the edge of being popular: fog calculations.
Fog is a network connecting between the edge device and the cloud. On the other hand, Edge and more specifically refers to the calculation process of the device near the edge. Thus, the mist comprising calculating an edge, but fog will also contain the processed data to the desired final destination network.
Supporters OpenFog Consortium organization led by Cisco, Intel, Microsoft, Dell, EMC and Princeton University and Purdue University and other academic institutions are developing fog and edge computing deployment reference architecture.
Some people predicted edge cloud computing may be replaced. However, Co-Chair Dean of Engineering, Purdue University and OpenFog Union Mung Chaing think no one computing will dominate. Instead there will be a continuum. When you need real-time field data analysis, edge and fog calculation very useful.
Edge computing security
edge computing security coin has two sides. Some people think that security is theoretically better edge computing environment, because the data is not spread through the network, but close to the place it was created. The less data in the enterprise data center or cloud environment, if it contains one of the environment, the less data is vulnerable to attack.
On the other hand, some people think less secure computing on the edge of nature, because the edges of the device itself may be more vulnerable to attack. Therefore, when designing any edge or fog computing deployments, safety must be the most important. Data encryption, access control and virtual private network tunnel is an important element of protection edge computing systems.
Edge computing terms and definitions
with most technical areas, the edge computing also has its own vocabulary. The following is a brief definition of some of the more common terms
edge device:
The device may be any device that generates data. These sensors may be, production or other industrial machines or equipment for data collection.
Edge:
edge depending on the use case. In the field of telecommunications, it is perhaps the edge of a cell phone or it may be a cell tower. In the automotive program, the edge of the network may be the car. In manufacturing, it can be a machine shop; IT in the enterprise, the advantage may be a notebook computer.
Border Gateway:
A gateway is to complete the processing between edge computation and wider mist network buffer. Gateway is entering the larger environment beyond the edge of the network window.
Thick client:
it may be some data processing software edge device. This is in contrast, the thin client and thin client only transmit data.
Edge computing device:
Edge calculated using a range of existing and new equipment. Many devices, sensors and work at the edge of the machine can be equipped computing environment, it just has to access the Internet. Cisco and other hardware vendors with a series of rugged network equipment, these devices have an external device hardening, can be used for on-site environment. A series of server computing, systems integration and even hardware-based storage systems (such as Amazon Web Service's Snowball) can be used for edge computing deployments.
Mobile computing edge:
This refers to the expansion of the telecommunications system in the edge computing systems, especially 5G scene.
