excessive online ordering, it is no exception. As the IPTV system is widely deployed and the number of users increases significantly, excessive ordering of network services will become a common phenomenon. The video quality monitoring module-Cisco network analysis module monitors video streams in real time and actively sends alerts to operators when the image quality is degraded, so that operators can learn the root cause of the downgrade and solve the problem in a timely manner, avoid a large

In terms of the comprehensive performance of Cisco SUP720, how can we understand Cisco SUP720? You will find many methods on the network. The following article compares the performance in three aspects, hope to help the majority of fans. Compared with SUP720, The sup720-3BXL is mainly different from the PFC used by the two. The SUP720-BXL uses PFC3BXL, while the SUP720 uses PFCA, And the SUP720 can be upgraded to a SUP720-3BXL by replacing the PFC. Cisco SUP720 Scalability:◆ The number of Route

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

According to the layered model, VPN can be established on the second layer or on the third layer (some even classify some higher-level security protocols into VPN protocols .)

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
