RPR technology is the latest and most advanced ring network technology in the industry. The solution to build a large-scale education metropolitan area network using Huawei 3Com RPR technology has been widely used in the industry.
As a member of the RPR alliance, Huawei 3Com has been actively participating in the formulation and discussion of RPR standards, following the progress of the latest RPR. In product development, it will improve the RPR products at the access layer, aggregation layer and core layer, and fully support RPR on transmission equipment, routers and switches; support 622M ~ 10G rates, and provide support for Ethernet and SONET / SDH physical layer RPR product. As shown in the following figure (taking Quidway series products as an example):
Huawei 3Com's IP ring network provides an optimized protection switching mechanism, and combined with QOS of the upper layer protocol, can provide a more complete solution.
The RPR ring network is mainly used to establish a low-cost and high-performance IP metropolitan area network. As a bearer network for IP services in a metropolitan area network, it can also be applied to access networks and VPN service.
Huawei 3Com is also the industry's first manufacturer to introduce RPR ring network technology and apply it to metropolitan area networks. The nodes on the RPR ring can use NE80 / 40 series core routers, and each school campus network is connected to the nodes on the ring nearby. The 2.5G / 622M RPR ring network solution that Huawei 3Com can provide is also used in Shanxi Radio and Television Metropolitan Area Network and Xi'an Education Metro Area Network.
The fabrics of the backpack are mainly PU, canvas, cotton, Oxford, cowhide, polyester, denim, PVC, etc.
The canvas backpack is very durable, even if it is scratched with a small knife, it will not break very much. However, the rucksack is a casual style and is more suitable for casual clothes.
Leather backpacks generally use cowhide, sheepskin or ostrich skin, crocodile skin and python skin, etc. The leather bag has a good texture and is very resistant to dirt, but the price will be higher.
