The BigHammer6800 core switch of the WAN network adopts the distributed CrossBar and distributed switching architecture to solve problems such as large-capacity switching and multi-service provision, therefore, it can help users' networks better achieve these convergence.

universal CPU. The combination of their specialized processing power and low cost makes the DSP well suited to perform signal processing functions in VoIP systems.g.729 speech compression on a single voice stream is computationally expensive and requires 20MIPS, and if a central CPU is required to handle multiple voice streams while also performing routing and system management functions, it is unrealistic to use one or more DSPs to offload the computational tasks of the complex speech compress

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. A label ing table is constructed in the MPLS switch through the Label Distribution Protocol in advance, then, the IP datagram is encapsulated into the MPLS header to implement Fast Forwardin

ATM Circuit extension technology enables service providers to map multiple VLAN to a virtual circuit, or to map multiple virtual circuits onto a single VLAN. Using this technology as a component, service providers can set up multiple point to point networks on ATM and Ethernet to provide enterprises with more flexible and scalable Ethernet based services.Conceptually, providing Ethernet services on an ATM network is fairly straightforward, but encapsulating an ATM transport stream into a packet,

Port network's million core switch BigHammer6800 series core switches because of the use of distributed crossbar and distributed Exchange architecture, to solve the problem of large capacity exchange, multiple service delivery, so that can help the user network to better achieve these integration. For the fusion of data, voice and video service, the crossbar chip
