VPN technology-P, PE, CE what is P, PE, cempls vpn there are three types of routers, CE router, PE router and P router. The CE router is a client router that provides you with a connection to the PE router. The PE router is the operator's edge router, that is, the Label Edge Router (LER) in the MPLS network ), it processes the VPN data from the CE router or the label exchange path (LSP) based on the stored route information and forwards the data.

According to the triangle derivation, the following formula is obtained for calculating the distance between two points: C = s

switching technology, layer-4 switching has emerged. It expands layer-3 and layer-2 switching, supports more fine-grained network adjustment, and gives priority to communication streams. The layer-4 switch is a policy-based route. It is located on the layer-4 of the ISO Reference Model and uses the layer-4 information. According to the layer-4 Information, for example, the port number of the data packet in TCP/UDP is exchanged. It allows you to prioritize communication data based on application

QoS has a layer-2 CoS service level in the past) or a layer-3 IP PrecedenceIP priority level), but now it emphasizes the support capability of differential service DiffSew. Therefore, edge switches play a critical role in end-to-end QoS support as QoS inbound or outbound sites. Hardware Support for DiffSew is one of the key functions of the switch.

important applications based on the traffic of a specific application. In a sense, layer-4 Switching provides a service level COS in the network. This can reduce WWW or FTP traffic for an Intranet and set higher priority for E-MAIL or Telent traffic. Third, layer-4 switching is a process based on accelerated routing. Currently, stream or label-based routing technologies have also been released, for example, the Fast IP address and NHRP switch launche

The edge layer realizes the conversion between the backbone network and the wireless transmission, and provides the corresponding QoS and COS, mainly including the node send/receive wireless unit and the basic Channel group connected to the ATM or l2/l3 edge switch. The central layer optimizes co

layer-3 Switch provides both layer-2 and layer-3 IP exchanges, integrating the functions of the original layer-2 Ethernet switch and vro, greatly reducing users' costs. With the rise of broadband services, the application scope of layer-3 switches is constantly expanding, especially the rapid development of GE and 10G Ethernet technologies. As a result, layer-3 switches have gradually moved from enterprise networks to man networks, the expansion of application scope also promotes its design inn

The OBS network can be based on WDM Optical Networks to realize the exchange of burst data groups between different links and different wavelength channels. In the OBS network, Data grouping and control groups are transmitted over different wavelength channels with a different offset time.
