  In STP, because STP has suboptimal path and other factors, we use MSTP protocol to complete this experiment. MSTP can better solve some problems in the network, and MSTP is also compatible with STP and RSTP. Next, we see the configuration implementation: Step 1: first, we add a P address to the PC I believe you all know the basi ...

Configuring VRRP backup groups Principle overview:         When VRRP is configured as a single Backup group, all business is undertaken by the Master device, while the Backup device is completely idle and not fully utilized. VRRP can realize load sharing by configuring multiple Backup groups, which effectively solves t ...

Network Plugin flannel One solution for cross-host communication is Flannel, introduced by CoreOS, which supports three implementations: UDP, VXLAN, host-gw udp mode: use device flannel.0 for unpacking, not native to the kernel, large context switching, very poor performance vxlan mode: use flannel.1 for unpacking, native kernel support, bette ...

HTTP protocol 1. What is the HTTP protocol What is an agreement Agreement refers to the rules agreed by both parties or multiple parties and everyone should abide by The so-called HTTP protocol refers to the rules that the data sent needs to comply with when communicating between the client and the server The data in HTTP protocol is ...

Java network programming (V) -- ServerSocket (II) In the last blog Java network programming (IV) - ServerSocket (I) This blog introduces what is a server Socket and how to use it. This blog continues to introduce other knowledge about ServerSocket. Request queue length When the server process is running, it may listen to connection reque ...

Question: "a tcp server and a tcp client. After the client establishes a connection with the server, the server always sleep s, and then the client always sends data". Before answering this question, let's think about the characteristics of tcp and the general process of tcp sending data: First of all, tcp is a reliable transmission ...

1, Network programming 1. Computer network Multiple computers with independent functions in different geographical locations and their external devices are connected through communication lines to realize resource sharing and information transmission under the management and coordination of the protocol. Network programming: different comput ...

1. Introduction to Netty 1.1. Netty is a client server framework based on Java NIO. Using netty, you can quickly develop network applications. Netty provides a high-level abstraction to simplify the programming of TCP and UDP servers, but you can still use the underlying API. 1.2. The internal implementation of netty is very complex, but nett ...
