ZTE broadband metro network solution
As telecoms networks are in the shift to be packetized and broadband-based, All-IP has been the future development trend of service networks. According to prediction, bandwidth is expected to grow at an annual rate of over 30% in the next five years. The two-layer networking mode “IP over WDM” is gradually replacing the traditional three-layer “IP over SDH over WDM” mode at both backbone layer and metro layer, and the flat architecture enabling carriage of IP packets directly over photonic layer has been an inevitable trend. IP over WDM networking architecture poses new requirements for photonic layer WDM equipments, and WDM layer will take over the networking, service grooming and end-to end circuit monitoring and management functions originally provided by SDH networks.
IPTN: IP Bearer Network Solution Oriented to 2G/3G Mobile Backhaul
As the competition in the global telecom market becomes increasingly fierce, the 2G and 3G bearer services coexist, the traffic bandwidth increases constantly and the interfaces tend to be IP-based, the bearer networks are required to provide powerful multi-service bearer capability, statistical multiplexing, differentiated QoS, carrier-class service guarantee, high precision clock synchronization, and excellent network extensibility.
