support new computer network protocols. The new features simplify network devices and operations, and the upgrade will not be so troublesome when OSPFv3 is used. (2) The difference between IS-ISv6 and IS-ISv4 Another connection status Protocol widely used by carriers is isforipv6. We know that isis is a standard routing protocol (ISO/IEC10589) that was originally used to support dynamic protocols of CLNS networks. Because the design of

This is a creation in Article, where the information may have evolved or changed. Go 1.4beta1 just released, in Go 1.4beta1, go language stack processing way from the previous "segmented stacks" changed to "continuous stacks".

The current version of OPENSSL-1.0.2J does not support Google's CHACHA20 encryption algorithm. The CHACHA20 encryption algorithm is relatively safe relative to RC4, and is optimized for ARM's mobile phone, making it faster and more power-saving.However, the latest Intel processors and ARM V8 processors are optimized for AES-GCM encryption algorithms through the AES-NI instruction set, which is much faster than chacha20, so the Aes-ni encryption algorithm is preferred on devices that support AES-

Cornell's K. Birman (the originator of virtual synchronization)History of Virtual Synchrony ReplicationThis article describes the development history of Virtual Synchrony. Based on this article, the core documents of Virtual synchronization are sorted out as follows: • J.M. Chang, N.F. Maxemchuck, "Reliable broadcast protocols", ACM Trans. on. Computer Systems 2 (3), Aug. 1984, pp. 251-273• F. cristian, H. aghali, R. strong and D. dolev, "Atomic Broadcast: From Simple Message Diffusion to Byzant

There are many network protocols, such as isis, rip, ospf, and bgp. In large companies, network devices often run multiple network protocols, if no configuration is required between various network protocols, no information can be exchanged between devices. In this case, the routing redistribution technology appears, the purpose of Route redistribution is to achieve collaboration among multiple routing protocols. Routing redistribution principle: by a

Memcached is a free and open-source high-performance distributed memory cache system designed to accelerate the running of Dynamic Web applications by reducing the database load. The client communicates with the memcached server through TCP or UDP on port 11211. To abuse the memcached server, attackers can send requests to the target server through port 11211, disguised as t

CloudFlare the oldest and most common attack against non-DDoS attacks by protecting millions of websites. In traditional DDoS attacks, attackers control a large number of puppet machines and then send a large number of requests to the target server to prevent legitimate users from accessing the site.However, DDoS attacks have been evolving in recent years: attackers tricked users into attacking activities in a new and interesting way. Last year

Cucumbertown is an asset-heavy web site, and although we postponed all the action on Requiejs and then actively loaded JavaScript on demand, we made a lot of effort to load the underlying script. We have confirmed that Cucumbertown's loading time in the United States is 2.5 seconds, compared to other countries this is simply the speed of light, DSL equipment around the world a week delay is 43
