Huawei Helps Ningbo Digital TV Accelerate Rapid Development of New Value-added Services

2016-06-02 09:32:33 Author: Source:CTI ForumComment:0  Click:


At present, Ningbo Digital TV Co., Ltd. is sticking to traditional TV services. Broadband access services, VOD video on demand services, large customer dedicated lines for government and enterprises, value-added services such as safe cities, and wireless cities have inevitably become new radio and television services. Direction of development. Obviously, all these business needs require the IP metropolitan bearer network to provide network support. Therefore, the construction of a carrier-grade IP network based on IP with high bandwidth, high reliability, high security, operational management, and comprehensive carrying capacity and scalability of multiple services has become a follow-up full-service operation of Ningbo Digital TV Co., Ltd. The essential.
Compared with the aforementioned business requirements, the current IP MAN has the following deficiencies:
1 Backbone convergence network develops at a high speed and existing construction faces bottlenecks
Due to the long-time construction of the backbone network, with the large-scale promotion of VOD high-definition interactive on-demand services and IP broadband services, the gigabit bandwidth of the backbone aggregation IP network cannot meet the service requirements, and the video on-demand service needs to be developed at the backbone network level. Establish a 10G-based bandwidth support point, and allow room for expansion of 40G and 100G ultra-high bandwidth in the next 5-10 years.
2 Public network IP resources are limited, affecting the expansion of broadband services
Under the trend of rapid development of broadband access services, Ningbo Digital TV Co., Ltd. is facing the difficulties of the public network's IP scarcity and the need to provide access services for a large number of broadband customers. How to use the scarce IP addresses of public networks to ensure high-quality network access services for existing customers and to reserve space for more customer broadband access, which was encountered by Ningbo Digital TV Co., Ltd. in the operation of broadband service access services. Development bottlenecks. Network access service providers usually use NAT technology to provide network access for mass network users. In this technical background, the selection of an efficient and stable NAT device is one of the focuses of network construction. The equipment of the selected NAT needs to meet the high-speed network access requirements of the current user and meet the network access requirements of a large number of new customers.
3 Internet security threats affect existing customers' premium web experience
In an era when network security is increasingly being valued, providing secure network access for customers is an issue that Ningbo Digital TV Co., Ltd. cannot solve as a network service provider. Only by guaranteeing existing customers' network security access and ensuring the existing customers' high-quality network experience can they retain existing customer resources and create a positive social reputation through quality, efficient, and safe online experience, bringing more new products to the broadcasting and TV enterprises. Customers, bring more revenue.
After fully implementing the existing network analysis and business research, Huawei based on its rich practice in the broadcasting and TV industry for many years, tailored a new generation of advanced IP MAN solution for Ningbo Digital TV Co., Ltd. The solution has a clear network hierarchy, a reasonable structure, and simple operation and maintenance: The VOD on-demand core deploys two Huawei new-generation cloud engine CE12808 switches to support 40G and 100G capacity expansion. The IP broadband core deploys two Huawei multi-service control gateways, the BRAS. Four USG9560 high-end firewalls are deployed at the entire network exit. At the same time, two T-bit high-end switches S9706 are deployed at each rendezvous point. The dual-star 10G uplinks are connected to CE12808 and BRAS, and links are backed up. The solution specifically addressed the above three business pain points, as follows:
1 "High Bandwidth", High Density 10G, 40G, 100G Board Card Interconnect
VOD on-demand system core deploys two Huawei CE12808 switches. A single switch can provide up to 86Tbps backplane capacity, 9600Mpps complete forwarding capability, and with a maximum of 192 40G, 64 100G ultra-high port density, Ningbo Digital TV A large number of lower-level access units have provided capacity for continuous expansion and enhancement of network bandwidth. Solved the pain point of the first bandwidth.
2 "unlimited port NAT" patented technology, public network IP will no longer be insufficient
Utilizing Huawei's patented technology to provide an "unrestricted port" connection algorithm that guarantees the use of a public network IP address can provide unlimited concurrent connections, to meet the actual use of the address translation method, more IP address resources in Ningbo Digital TV Co., Ltd. In the scarce situation, high-efficiency access to the current large-scale users is met, and at the same time, space is reserved for massive new users. Solved the pain points of the second public network IP is not enough.
At the same time, the USG9560 is the industry leader in its architecture and performance. It implements mutual backup and traffic load balancing, and provides a smooth evolution path to the 100G platform through a linear expansion method.
3 "High Security", 15 years of deep accumulation in the field of network security to meet the needs of network security protection
Huawei deployed two of Huawei's highest-end USG9560 firewall devices at key locations on the metropolitan area network for Internet security protection. From the beginning of 2000, Huawei began to research and develop network products in Russia, and accumulated a great deal of profound security protection experience in the field of operators. Huawei's highest-end USG9560 has a maximum number of concurrent connections of 40 million, new firewall processing performance of 25 million connections per second, and seven-layer filter protection capabilities, 6000+ network depth protocol analysis capabilities, and 60 million URL classification library capabilities. At the same time, many security functions such as IPS intrusion prevention, AV anti-virus, DPI network application flow control, URL classification filtering, and RBL spam protection are enabled to fully meet the increasingly complex requirements of Internet security protection. In addition, the linear expansion of the performance of the card increases the space for subsequent expansion. These security guarantees solved the third network security pain point.
In addition, because the USG 9560 firewall is deployed on key nodes of the network, its 99.999% stability based on carrier quality guarantees that service interruption will not be caused due to a firewall failure, and network stability will not be reduced due to the addition of network nodes.
After deploying Huawei's new-generation IP metropolitan area network, Ningbo Digital TV has gotten rid of the old basic network bottleneck, and new services have been rapidly developed. The number of users of broadband access services and VOD video on demand services has increased by several times within one year. . In addition, relying on advanced IP network platform support and Huawei's powerful back-end after-sales service, Ningbo Digital TV quickly won several dedicated local local customer service projects, as well as video surveillance and WLAN wireless coverage in districts and counties. Value-added services have since entered the rapid development path.
Ningbo Digital TV Co., Ltd. customers think:
“The new generation of IP MAN created by Huawei for us has not only provided a high-speed and secure network access experience for our individual, corporate, and government customers, but also reduced the difficulty and cost of our operations management. The scalability is very good, and it has truly reached the tripartite win of the users, us and Huawei."
