cleaning device.In addition to BGP, Policy Routing and MPLS can achieve traffic traction technology.Back noteAs with the flow traction, the process of the callback is also implemented by specifying a router policy, which avoids the formation of loops after the traffic in the cleaning device arrives at the router.Traffic callback can generally take 3 ways, Policy Routing, routing policy and VLAN.The policy route takes precedence over the normal route,

Nortel offers complete optical Ethernet solutions, including Ethernet over Fiber, Ethernet over resilient Packet rings (RPR), Ethernet over DWDM, and Ethernet over SD H et. 3Com copper wire Gigabit in the global market share of nearly 30%, mainly because 3Com products easy to install, management and maintenance, can be said that 3Com of Gigabit Ethernet technology to popularize the work.

The WAN network solution is also trustworthy in terms of integrated exchange routing and IPv4/v6 network convergence. BigHammer devices not only support a wide range of routing protocols, but also use MPLS technology to solve the biggest challenge facing the

Quidway S8500 series 10-Gigabit core multi-service routing switch is a new generation high-performance 10-Gigabit Core routing switch developed by Huawei 3Com, it can be widely used in the core layer of E-government network, campus network and education man core layer, campus network and enterprise network core layer, carrier IP Man core layer, and convergence layer.Quidway S8500 is designed based on the 10G platform and supports a new generation of high-performance 10g interfaces. It can provid

billion (including exchange and transmission products ). In contrast, revenue from traditional optical crossover products based on Sonet/SDH continued to drop by 2013 in 22% to $0.2 billion. From these figures, we can see some obvious trends: G is driving the growth of core network spending and affecting the decision-making process of carrier's core network architecture. At present, OTN is the clear choice of the carrier's core network, and we believe it will continue in the next five years. Th

. If the link layer technology itself does not have a routing mechanism, it encapsulates an x.5 layer, and the ATM switch implements the link layer routing well, by establishing a virtual channel to build a forwarding link for the upper layer of data, or even layer-3 technology, we all know that IP Forwarding is very slow (Cisco CEF technology is not considered for the time being ), as a result, the MPLS layer 2.5 is implemented.

unrealistic to use one or more DSPs to offload the computational tasks of the complex speech compression algorithm from the central CPU. In addition, the DSP is also suitable for voice activity detection and echo cancellation such functions, trapped in their real-time processing voice data stream, and can quickly access the board memory, so. In this section, we describe in more detail how to implement speech coding and echo cancellation functions on the TMS320C6201DSP platform.　The main technic
