What is SDN?
SDN: Software Defined Network, which is a revolutionary change that solves some of the inevitable problems in traditional networks, including lack of flexibility, slow response to demand changes, inability to virtualize the network, and high costs.Under the current network architecture, network operators and enterprises cannot provide new services quickly because they have to wait for equipment providers and standardization organizations to agree and integrate new functions into a proprietary operating environment.This is obviously a long wait, and perhaps by the time the existing network actually has this new capability, the market will have changed a lot.
SDN Benefits as follows:
No.1 - SDN provides more flexibility for network use, control and how to generate revenue.
No.2 - SDN speeds up the introduction of new services.Network operators can deploy related features through controlled software, rather than waiting for a device provider to add a solution to its proprietary equipment.
No.3 - SDN reduces the operation cost and error rate of the network, because it realizes the automatic deployment and operation and maintenance fault diagnosis of the network and reduces the manual intervention of the network.
No.4 - SDN helps to realize the virtualization of the network, thus realizing the integration of computing and storage resources of the network, and finally enabling the control and management of the entire network to be realized through the combination of some simple software tools.
No.5 - SDN makes the network and all IT systems better oriented to business goals.
SDN Network Packet Broker Applications:
After sorting out the main participating entities of the network, the application scenarios of SDN basically focus on telecom operators, government and enterprise customers, data center service providers and Internet companies.The application scenarios of SDN mainly focus on: data center network, interconnection between data centers, government-enterprise network, telecom operator network, and business deployment of Internet companies.
Scenario 1: application of SDN in data center network
Scenario 2: application of SDN in data center interconnection
Scenario 3: application of SDN in government-enterprise network
Scenario 4: application of SDN in telecom operator network
Scenario 5: application of SDN in the service deployment of Internet companies
