clos network การใช้

• Clos networks may also be generalised to any odd number of stages.
• There are multistage designs for crossbar systems, such as Clos networks.
• This is called a Clos network.
• Clos networks have three stages : the ingress stage, middle stage, and the egress stage.
• Connecting the two SSUs in parallel this way provided the doubling of network capacity required in a CLOS network.
• This topology is actually a special instance of a Clos network, rather than a fat-tree as described above.
• In the context of a Clos network, each boy represents an ingress switch, and each girl represents an egress switch.
• By replacing each centre stage crossbar switch with a 3-stage Clos network, Clos networks of five stages may be constructed.
• By replacing each centre stage crossbar switch with a 3-stage Clos network, Clos networks of five stages may be constructed.
• The way to solve this problem is to replace the single MXM crossbar switch in a multi-stage format ( see Clos network ).
• To support routing in hierarchical networks, such as multi-stage butterfly or Clos networks, the STC104 provides a mechanism for header deletion.
• One early, successful mathematical analysis was performed by Charles Clos ( ), and a switched fabric constructed of smaller switches is called a Clos network.
• The STC104 can be used to construct a variety of network topologies, including multi-dimensional Clos networks ( and the closely-related Fat tree ).
• *Nonblocking Minimal Spanning Switch-Needs work from someone knowledgeable about some of the theoretical underpinnings of telephone networks, things like Clos networks in their rearrangeably nonblocking form.
• If this middle-stage switch is now removed from the Clos network, " m " is reduced by 1, and we are left with a smaller Clos network.
• If this middle-stage switch is now removed from the Clos network, " m " is reduced by 1, and we are left with a smaller Clos network.
• The Jacobaeus approximation is more accurate, and to see how it is derived, assume that some particular mapping of calls entering the Clos network ( input calls ) already exists onto middle stage switches.
• The word " non-blocking " was traditionally used to describe telecommunications networks that could route a connection through a set of relays " without having to re-arrange existing calls ", see Clos network.
• There are " i " input calls entering via the same ingress switch as the free input terminal to be connected, and there are " j " calls leaving the Clos network ( output calls ) via the same egress switch as the free output terminal to be connected.
• If " m " e " 2 " n " & minus; 1, the Clos network is " strict-sense nonblocking ", meaning that an unused input on an ingress switch can always be connected to an unused output on an egress switch, " without having to re-arrange existing calls ".
