A large enterprise/company needs to be distributed across the country branches or offices across the wide area network, so as to share information resources between each other, because the need to transfer data on the public data network, it is known that the public data on the Internet transmission of data information is not particularly safe. To improve the security of the data being transmitted, consider using a secure router. A secure router can hide the network topology diagram within the c

I often talked about the problem of IPv4 and IPv6 integrated networking, and raised a lot of questions. I believe you have some knowledge about it. We will not talk too much about it here. Through the centralized and integrated networking strategy, we also found some features. Now let's make a summary to see which important factors should be taken into consideration when selecting specific technologies for

. For bank users, there are usually few daily transactions in rural savings offices, and the required bandwidth is 1 to 2 64 K. Therefore, it is difficult to recover the investment by covering the DDN network in rural areas.Second, due to the geographical distribution of large users in cities, nearby access is very important for operators to save investment. For the DDN network that has been built, it is difficult for the Operation Department to add DDN devices to meet the new user needs of grow
