Data grouping header based on the needs of various applications, that is, set the priority for the Data Group. The management of network data is completed by users. Diff-Serv is only a protocol used to prioritize data. Based on the user's network, IP groups with different priorities are encapsulated into frame relay or ATM cells and transmitted over the user's network. Data passes through the user's network and arrives at the entry switch, where frame relay or ATM cells are unblocked as downstr

control measures. Different from the traditional Internet, a telecom network must be a network that can be strictly managed and controlled so that the network can fully realize the intentions of operators. Operation-level routers must support at least the SNMP Network Management Protocol, and can accept and provide various standard management information libraries (MIB) through SNMP ). At the same time, it is best to support general policy configuration (COPS) to facilitate unified configuratio

PPP protocol, this is the structure of IP over SONETPOS. This structure quickly replaces ATM and becomes the mainstream technology of Internet broadband backbone networks. It increases the transmission efficiency from 80% to 95% and simplifies the equipment and reduces costs. IP over SONET is not the ultimate System of layered simplification. It can further simplify the SONET layer in the broadband backbone network and directly run the IP Application on the Optical channel IP over Optical ). Al

I have a Cisco 3640 router with FXS, FX0, and E/M voice cards. Can I use a PBX (dedicated group switch) with this router? Can you provide an example to illustrate how to call different Cisco 2612 routers in other locations through the PBX vswitch on the MPLS network? First, there is no difference in MPLS. It is only an IP transmission network. Your 3640 router can be used together with the PBX. FXO can help

sites for different SPS. However, as part of the mutual trust protocol between SPS, VPN-IPV4 routing can only be accepted by EBGP connections between private peers. Vpn-ipv4 routing cannot be distributed on the public Internet or accepted by the public Internet. If the sites of many VPN configuration instances are connected to different autonomous systems, there is no need for a ASBR of all VPN routes between the different autonomous systems, and there can be multiple asbr, each ASBR only part

In Tang xiongyan's view, the operator needs to formulate detailed user policies and billing policies. "The operator sends detailed billing policies to the policy server based on the behavior of each user and sends instructions to the Service Router, the Service Router technology makes corresponding behavior adjustments according to instructions." He told

The TRILL, SPB, FabricPath, VPLS, and other technologies for large-scale network expansion solve the shortcomings of the above technologies, but they have special requirements on the network, that is to say, all devices in the network must upgrade hardware and software to support such new technologies, resulting in an increase in depl

Looking forward, there is a number of tunneling protocols being developed to connect virtual switches, Including:gre, MP LS, VPLS, VXLAN and NVGRE. As new protocols is deployed on the network they is easily monitored without any change to exiting SFlow agents ensuring End-to-end visibility across the

There are many things worth learning about ATM switches. Here we mainly describe how to improve the flexibility of the open call to improve the flexibility of the ATM switch. The telephone product has always been known for its reliability. One of the reasons is that it supports multiple protocols, different types of voice transmission streams can be transmitted on a single platform. A new architecture called the open call model can give the data platform the same level of flexibility: it allows

The Group switching method has the advantages of packet switching and line switching. Grouping switching technology uses statistical multiplexing, which greatly improves bandwidth utilization compared with circuit switching. This requires the use of storage and forwarding on the switch node, resulting in leeching. Therefore, the concept of
