video transmission in wide area networks Aug 4th, 2021   [viewed 40 times]
It collectively transmits the data to the other party without establishing a connection. It is used in real-time data transfer such as voice and video transmission in wide area networks (WAN). In addition, UDP is more preferred for games. UDP is an untrusted and generally not preferred protocol because it only transmits data according to the speed of the data generated by the application, the capability of the computer and the transmission bandwidth limit. UDP doesn’t think that every packet needs to reach the receiving end, so the network load is smaller than TCP. At the same time, the transmission speed is faster than TCP, but the congested the network the more risk it loses the packet sent. So what are the other differences between TCP and UDP? It is very important that communication be effective and secure in the business world. Sharing the information in the right place at the right time facilitates the distribution of business processes. Some database services provide error-free management of IP phones and call decisions. With the given configuration commands, the nature of the communication is preserved and is not broken. The Linux-based communication server supported by Cisco Systems that maps IP numbers to phone numbers and integrates voice, video, data and mobile applications is called Cisco Unified Communications (CUCM) or Cisco Call Manager (CCM). It doesn’t allow sharing unnecessary files on the server with TFTP (Junk File Transfer Protocol). A CUCM cluster can have a maximum of 20 servers, while only one publisher server is allowed in the cluster. The publisher contains the information in the database. Up to eight subscriber servers can be in the same cluster, as only four of the subscriber servers can perform active calls. If more than four subscriber servers are used in a cluster, the additional servers are being dedicated as backup servers in case the active subscriber server is unavailable. The other 11 servers in the cluster may be responsible for a variety of services, including TFTP and media resources. It consists of a CUCM license, license server and license manager. While the license server component runs only on the publisher server, the license manager runs on each server. More info: what is f5
