12 Global growth of cloud-based services

13 Reasons to change the behavior and habits of the audience and their tendency towards online digital content The main reason for changing the taste and habits of the audience is the only change in technology and business models that has been able to multiply its audience over the short term. IABM's survey shows that the Broadcasting IP Base has multiplied the trend of customer behavior

14 The cause of the chart is the most important commercial in the various fields of the Broadcasting industry The most important possibility in the Broadcasting industry is its commercialization. Setting up multiple services - User friendly according to taste - The customer needs and demands require a lot of infrastructure resources in this area. So for economic justification we need to change the business models and design and update new data centers with the ability to virtualize resources.

15 The trend towards product vendors moving toward virtualization

16 Areas of the industry will be affected by virtualization Video Storages Software Defined Storages and cloud Storage such as Scalaty Online Video Processing Will run On the Virtualized Environments Based On Commodity Hardware Such as Ericsson, Cisco, Thomson,. Video Platforms As Service Video IP Transition and Network Infrastructure Software Defined Network and NFV

18 Content Delivery Network(CDN) The Content Delivery Network, also called the CDN, is a large network of servers that are deployed in several parts of the world and are geographically distributed. Using the CDN, the user provides the user with the user's geographical location from the nearest server. The service is very influential in speeding the delivery of content and bandwidth in hightraffic services.

19 Advantages of using CDN Increase the sustainability and accessibility capability by distributing content in different geographic locations

20 Advantages of using CDN Reduce the impact of DDOS attacks on services through the distribution of traffic loads of attacks to various sources

21 Advantages of using CDN Avoid system server overflow of HDD / MEM / CPU and Bandwidth network infrastructure as service requests increase.

22 Advantages of using CDN in OTT Services Enhance the availability and satisfaction of users Providing security solutions to provide content in a secure environment for content services ا Avoid copying content as well as encrypting all audio and video content in addition to encrypting all communications. Creating secure thread links for each user and each IP with the possibility of creating an expiration date in time DRM support Optimized high-traffic management on the network Selling and charging users for access to services High security in content access Creating massive data gathered from users Identify the interests of users in content as well as business products and applications Very advanced monitoring for all the events of the service and users Extremely Scalable etc

26 Cloud-based OTT services (live audio and video, Catchup services, etc.)? Sample: The OTT chain provided by the BBC over the cloud

27 Network infrastructure virtualization The studies conducted by the world's largest broadcasting companies point to the importance of using SDN and its impact on the business model.

28 Characteristics of the Future Sound Architecture Architecture Draw by the JT-NM Working Group The JT-NM is a very strong voice and image cycle that, with the virtualization and design of the SDN, has been able to provide the main infrastructure for audio and video processing in this area. This highlights the importance of moving towards data center design and virtualization in the Broadcasting industry more than ever.

29 PART 2 Infrastructure Implementation Plan for Imam Ali DataCenter in the network segment and its current capabilities regarding CDN and Cloud

30 Introduction of Infrastructure Imam ALI Data Center of in Network Division The organization needs to have fast, highspeed, and uninterrupted network infrastructure for providing content of the highest quality and speed. Accordingly, the network infrastructure is based on the new Leaf-Spine model, which provides a high-speed, high-latency dataprocessing machine.

31 The benefits of Leaf-Spine design and fixing existing infrastructure problems One of the reasons why internal users forced the organization's services to use island infrastructure (including processing, storage and networking) is the lack of a high-speed, low-latency network fabric. In the case of a high-speed, low-latency network, it is possible to eliminate island and encrypted systems that impose many costs on the organization.

32 East-West data center traffic and high-speed 40G / 100G connections The greatest demand for bandwidth is in the current data center of East-West traffic (the traffic between the nodes inside the datacenter and not out of the data center infrastructure) For this purpose, 40G / 100G connections will be used and there will be a high-bandwidth network (1: 1 over subscription) between the nodes.

33 East-West data center traffic and high-speed 40G / 100G connections

34 Infrastructure and Services Security in Data Center (East-West Traffic) Due to the high volume of East-West traffic that requires high bandwidth and low latency, we need special equipment in this regard. Detecting high value assets and deploying appropriate tools to ensure the sustainability and security of services is the most important part of data center security design. The equipment of this part generally has a Flow Accelerator, which has a minimum of latency on the infrastructure.

35 Guaranteed quality of WAN services through traffic engineering In the North-South traffic segment, we need to use different tools to detect more complex attacks that are generally external. Events include DDoS attacks, malware, unauthorized access to infrastructure and services.

36 Architecture required in the CDN infrastructure The CDN infrastructure is compliant with architecture and basic standards, which is optimized according to the needs of the IRIB organization

37 Content storage on Cache Server Detecting the Lowest and Most Demand for Content FIFO patterns Storage location in Memory or HDD / SSD disks

38 CDN Infrastructure and Optimal Content Distribution Techniques Directing users to the best Cache Server is possible based on one or a combination of the following methods -DNS -ANYCAST

39 CDN Infrastructure and Optimal Content Distribution Techniques -Directing users to the best DNS-based Cache Server -Traffic distribution is based on the IP of the Recursive DNS server, which is configured on the user's device, including PC, Mobile, Tablet.

40 CDN Infrastructure and Optimal Content Distribution Techniques -Leading users to the best Cache Server based on ANYCAST

41 CDN Infrastructure and Optimal Content Distribution Techniques -Leading users to the best Cache Server based on ANYCAST -All nodes (like cache servers) are known by a fixed IP address on the Internet

42 CDN Infrastructure and Optimal Content Distribution Techniques -Leading users to the best Cache Server based on ANYCAST -All nodes (like cache servers) are known by a fixed IP address on the Internet -Distribution of traffic based on routing-based mechanisms (BGP Routing)

43 Connect to the network infrastructure of major Internet service providers and deploy Cache servers -To distribute content from the Origin servers based on the organization's datacenter, it needs the appropriate network bandwidth for large ISPs. Major service providers for deploying services: telecommiunication company MCI Irancell Asiatech Hiweb Parsonline Shatel

44 Connect to the network infrastructure of major Internet service providers and deploy Cache servers To distribute content from the Origin servers based on the organization's datacenter, it needs the appropriate network bandwidth for large ISPs. IXP Infrastructure provides a high-speed connection between ISPs and content providers:
