Applications for dtn-based communications Ways of exploiting dtn characteristics for communication and cooperation in mobility communities. Mobility models and dtns in mobile Ad-hoc networking.

bytes has been sharply reduced to 2 bytes, And the latency has been reduced from 150 milliseconds to 50 milliseconds. In fact, these two factors are enough to interest Google ". By simulating full-duplex connections in a browser, HTML 5 web socket significantly improves web communication. Let's look at how HTML 5 web socket reduces unnecessary network traffic and latency compared with traditional solutions. Current web communication-Headache round robin(Polling) Generally, when a browser a

When polling is used, the browser regularly sends HTTP requests and immediately receives responses. This is the first attempt to deliver real-time information. Obviously, if you know the time interval of message t

IPv6 adoption: Challenges and Choices, and ipv6 adoption challenges Today, many enterprises have begun to adopt IPv6 (Internet Protocol version 6th), and more countries are preparing to increase IPv6 traffic globally. As more and more devices connect to the Internet (such as smart cars, smart homes, and even smart cities), and the available IPv4 address pools quickly run out, today's network space has become more important than ever before. However, using NAT (Network Address Translation) as th

of our designs. In some cases, we can test the options with small sample users, like the prototype test for my TV page mentioned above. For other situations, like verifying the use of sidebar navigation, you need to look at the actual usage records of a large number of users. At this point, we need to use A/b Test. For A/b test for mobile applications, we use swrve--, the most mature A/b test tool in my opinion, which not only provides goal seeking (when the winning solution is clear, A/b test
