If the two namespaces are in different subnets, they cannot be connected through the bridge. Instead, they need to perform Layer 3 forwarding through the router. However, Linux does not provide a virtual router device like a virtual bridge because Linux itself has a router function. The working principle of the router is this: there […]

[Docker] Linux bridge connects multiple namespaces
veth implements a point-to-point virtual connection, and two namespaces can be connected through veth. If we need to connect three or more namespaces to the same layer 2 network, we cannot just use veth. In a physical network, if we need to connect multiple hosts, we will use a bridge, also known as a switch. […]

Python namespaces and scopes
The so-called scope refers to the scope within which the variable name/object name is visible/valid. A variable name cannot have a scope that is too large, which will cause widespread naming conflicts, nor is it too small, which will make it difficult to implement the variable’s scope. Shared, so there are generally multiple levels of […]
Namespaces, function objects, and closures
1. Namespace 1. What is a namespace The namespace is where the mapping/binding relationship between names and objects is stored. For x=3, Python will apply for memory space to store object 3, and then store the binding relationship between the names x and 3 in the name space. del x means clearing the binding relationship. […]

C++ namespaces & templates
Namespace In order to distinguish functions, classes, variables, etc. with the same name in different libraries, the concept: namespace is introduced. It serves as additional information to help differentiate between them. Using a namespace defines a context, which essentially defines a scope. Define namespace A namespace is defined using the keyword namespace, followed by the […]
