Both the edge and center of the MPLS network can use cisco MPLS products: edge devices, or edge exchange routers (edge LSR), which are a full-featured layer-3 device, the L2 Switch or L3 router can be marked as an LSR.

HTML5 practice and analysis: offline applications
Offline Web applications can run when devices cannot access the Internet. HTML5 focuses on offline applications and focuses on developers' wishes. The steps for Offline Application Development are as follows: First, you should know whether the device can access the Internet, and then you should be able to access certain resources (such as CSS and JavaScript). Only in this way can you work normally.
Offline Detection

This difference will lead to increased costs, not only against the manufacturers, but also confusing users. They finally reached a consensus, so in today's world, 9 holes per inch of piano paper roll has

However, it also has disadvantages. In real enterprise-level development, there are usually many tables in the database, and the business is complicated, naturally, there is a lot of one-to-many relationships between tables. This relationship not only brings a lot of performance load to hibernate, but in this case, the VO cannot use the shortest copy, because there are still objects in the object, such a JavaBean should be a heavyweight Object if there are many associated objects.
