to devote to this task . But, reassembly is very inefficient on a router whose primary job are to forward packets as quickly as possible. A Router is isn't designed to hold in to packets for any length of. Also a router doing reassembly chooses the largest buffer available (18K) with which to work because it has no way of know ing the size of the original IP packet until the last fragment is received. The Another fragmentation issue involves handling dropped. If One fragment of a IP datagram

To support container Cross host communication, Docker provides overlay driver, allowing users to create overlay networks based on Vxlan. Vxlan can encapsulate two-tier data into UDP for transmission, Vxlan provides the same Ethernet two-tier service as the VLAN, but with greater scalability and flexibility. More detailed information about Vxlan can be referenced in the relevant chapters of Cloudman's 5-minute play OpenStack every day. Docerk Overlay network requires a Key-value database to hold

If you have also used Consul, you can use the Docker one-click Deployment: docker run -d -p 8500:8500 --name consul consul The dependency of Winton.Extensions.Configuration.Consul is then introduced into the Application portal project. Because it is a personal open source, there will inevitably be some problems, such as my versi

The Spring Cloud Consul project is a service governance implementation for consul. Consul is a distributed, highly available system that contains multiple components, but as a whole, a tool for providing service discovery and service configuration for our infrastructure in the microservices architecture. It contains the following features:Service discoveryHealth CheckKey/value StorageMulti-Data centerThanks to the implementation of the spring Cloud Consul project, we can easily register spring b
