The LightStream 1010 ATM switch is Cisco Systems' next-generation ATM switch for workgroup and campus backbone deployment. Incorporating support for the latest ATM Forum specifications and building upon the Cisco Systems' Internetwork Operating System (IOS) software, the LightStream 1010 offers the most complete, sophisticated feature set of any ATM switch in its class. It also provides the performance, scalability, and robustness required for production ATM deployment.
The LightStream 1010 uses a five-slot, modular chassis featuring the option of dual, fault-tolerant, load-sharing AC or DC power supplies (see Figure 1-1). The central slot in the LightStream 1010 is dedicated to a single, field-replaceable ATM switch processor (ASP) module that supports 5-Gbps shared memory and a fully nonblocking switch fabric. The ASP also supports the feature card and high-performance reduced instruction set (RISC) processor that provides the central intelligence for the device. The remaining slots support up to four hot-swappable carrier modules (CMs). Each CM supports up to two hot-swappable port adapter modules (PAMs) for a maximum of eight PAMs per switch, maintaining a wide variety of desktop, backbone, and wide-area interfaces.
See the following documents for detailed ASP and chassis configuration information:
The LightStream 1010 ATM switch should be installed in a standard 19-inch (48-centimeter) rack.
ATM delivers important advantages over existing LAN and WAN technologies. These features allow many new classes of applications, such as multimedia, to use ATM technology.
The structure of ATM cells and cell switching facilitate the development of hardware-intensive, high-performance ATM switches. The deployment of ATM networks, however, requires the overlay of a highly complex, software-intensive, protocol infrastructure. This infrastructure is necessary to allow both individual ATM switches to be linked into a network, and to allow such networks to function with the installed base of existing local and wide-area networks.
See the LightStream 1010 ATM Software Configuration Guide and LightStream 1010 ATM Switch Command Reference for detailed description of ATM functions and network configuration.
The LightStream 1010 ATM switch provides Layer 2 switching, with both local and remote management.
Figure 1-2 shows an example of a network configuration using the LightStream 1010 ATM switch in a high-performance workgroup.
Figure 1-3 shows an example of a network configuration using the LightStream 1010 ATM switch for a campus backbone.
Figure 1-4 shows an example of a network configuration using the LightStream 1010 ATM switch in a multi-site network.
Figure 1-5 shows an example of a network configuration using the LightStream 1010 ATM switch in a LANE network.
Figure 1-6 shows an example of a network configuration in which private switches form a private network interconnected over permanent VPs. These VPs provide logical trunks tunnelling across a public network.
