Huawei SPTN solution helps Hebei electric power build a packet transmission network
customer background
Hebei electric power company is a large state-owned backbone enterprise subordinate to the State Power Corporation, which is responsible for the construction, operation and dispatching management of electricity in the southern region of Hebei Province, including Shijiazhuang, Baoding, Cangzhou, Hengshui, Xingtai and Handan. Serving more than 49 million people, it has the dual attributes of basic industry and public utilities, and bears an important 6 LP r l a m 03001 represents LP series, push-pull rod, dial pointer refers to zero 7-foot cable, 4 ⑵ 0ma output, metric stroke 300mm, 24V input politics, society and economy. Under the group's integrated three sets and five systems, a more efficient basic communication platform for communication, scheduling and management is needed, and a future oriented packet bearer that supports increasing IP services, high bandwidth, high reliability and intelligence is needed
grouping and multi service bearer call for a transmission network with large bandwidth, rigid and flexible
with the continuous development of Hebei electric power, the proportion of grouping services is increasing, and the consumption of bandwidth by grouping services is greatly increased. At the same time, for different services such as video conference, scheduling, monitoring, OA, etc., there are different requirements for bandwidth, delay and other transmission performance, such as video conference, which needs the guarantee of high bandwidth and low delay; Although key tasks such as scheduling and monitoring do not necessarily require high bandwidth, they attach great importance to low latency and need to be guaranteed by rigid pipelines; For OA and other data services, statistical elastic pipes can be used to improve the utilization of network bandwidth
traditional SDH Networks can provide rigid pipelines, but with the continuous development of packet services, the demand for bandwidth increases rapidly. If a pure rigid pipeline network solution is adopted, the bandwidth utilization rate is low, and it can only be met by continuously increasing the network bandwidth. Considering the cost of operation and maintenance, this is unrealistic. Therefore, the transmission network needs to have the ability to provide rigid pipelines and elastic pipelines for statistical reuse
Huawei PTN solutions have met the future network development needs of Hebei electric power for many years
according to the needs and pain points of Hebei electric power customers, combined with the long-term business development strategy of electric power, Huawei solutions adapt to the needs of customers, adapt to the grouping trend of the power industry, and use PTN series products ptn/1900/910 to form a ring according to the core layer/convergence layer/access layer, and form a ring according to the county transmission backbone, The backbone transmission bandwidth is increased to 10GE, and the 1000m access of the power supply station is realized. While meeting the large bandwidth requirements of packet services, the whole transmission network has the ability of rigid pipeline and statistical multiplexing elastic pipeline. Rigid pipelines can be used for monitoring, scheduling and other businesses with high real-time requirements; For OA and other large bandwidth ordinary data services, the elastic pipeline of statistical multiplexing can be used to greatly improve the bandwidth and efficiency of power communication
instead, I smell a fragrance similar to corn
Huawei SPTN solution has perfect differentiated service capabilities
Huawei SPTN solution has perfect QoS capabilities of bandwidth statistical multiplexing and differentiated services, and can provide differentiated service quality according to the different needs of various businesses (such as voice, video, monitoring and data, etc.). SPTN solution creates a rigid and flexible packet transmission network, which can provide rigid pipes and dedicated bandwidth for specific users or services, avoid and manage network congestion, reduce message loss rate, and regulate network traffic; At the same time, it can provide an elastic pipeline for statistical reuse to meet the bandwidth guarantee requirements of different service levels. In addition to traditional QoS capabilities, Huawei SPTN solution also has hierarchical QoS (HQoS) capabilities. Through hierarchical QoS control at different levels, it can provide refined QoS services for each business
