Description
SWITC~ F~.~ NF.TWO~K
Field of th~ Invention The invention relates generally to the field of circuit switching and more particularly, to a system of providing comm~lniration paths between multiple devices with multiple links conn~cted to each device.
~rolln~l of th-o ~nvention In telephone ne~wol~, co,l~ut~,r ll~lwul~, etc., many devices co. ~ ;r~l~ with many other devices. Due to the large number of possible combinations of devices which may co.. ~ r~t~ with each other, it is generally conside.~d illly.aclical and inefficient to dedic~te 10 unique physical co..----~ ir~tion links to each pair of network devices. Tn~te~d, ~wilches logically configure co.. ~ l;on links ~l~n all devices with physical links being located only ~t~e~n the switch and each device.
While these ~wi~hes are very erri~ and plà~;liCal for large scale networks, they are costly, consume power and take up valuable space in smaller ~lwol~.
As such, the need exists for an in~x~ncive device, which is smaller than a switch, co~.~ es less power than a switch, but can provide the same results as a switch for a limited number of devices.
It is accordillgly an object of the present invention to provide a module of de~1ic~te(1 co~ ui-ir~tion links.
It is another object of the present invention to provide such a module which connects to a backplane in a slot which is reserved for a switch.
It is still another object of the invention to provide such a module for use with an Asynchronous Transfer Module (ATM) network.
It is another object of the invention to provide such a module for a limited llulllber of devices.
It is still another object of the invention to provide such a module which does not require power from the system to operate.
These and other objects of the invention will beco~e appalelll to those skilled in the art from the following description thereof.
CA 022~34~ 1998-12-09 S~mm~y of thP Inve~tion It has now been discovered that these and other objects may be accomplished by the present apparatus for and a method of providing communication paths between network devices.
According to one embodiment, the invention includes a net~vork shelf which includes a S backplane having multiple device ports. It further includes multiple links connected to each of the device ports. Each of the device ports may be connected to at least one other device port through at least one ofthe links. The total number of device slots coupled together in a full mesh configuration should be no greater than one more than a total number of the links connected to one of the device ports. That number could be greater for a partial mesh configuration.
In another embodiment, the invention includes a method of providing communication paths between multiple devices selectively connected to a network shelf. The shelf may include a backplane having multiple device ports and multiple links connected to each of the device ports. The number of device ports conn~cted together in a full mesh configuration should be no more than, one more than the number of links conn~ cted to one of the device ports. This 15 embodiment provides a unique, de~ic~ted colllm~lication link bet~veen at least a first device port and a second device port.
According to another emb~lim~nt, the invention includes a switchless network including multiple devices each having mllltiple link intPrf~ces The total number of devices in a full mesh configuration should be less than or equal to one more than the total number of link interfaces 20 on one of the devices. This embodiment also in~ .1es mllltiple comml.nic~tlon links which may statically (but optionally reconfigurably) inte.-,om~ct each of the devices to one or more of the other devices. The co.. l-.-;c~tion links are connected bcl~,en the link interfaces.
The invention will next be described in com~;Lion with certain illustrated embo~im~nt~;
ho~ ,., it should be clear to those skilled in the art that various m~ifi~ ions, additions and 25 subtractions can be made without departing from the spirit or scope of the claims.
Brief DescriptioT- of th~ Drawin,~
For a fuller underst-qn~lin~ of the nature and objects of the invention, reference should be made to the following detailed description and accornpanying drawings, in which:
FIG. 1 is a block diagram depicting multiple devices connected in accordance with the S invention; showing details of a fully interconnected mesh.
FIG. 2 is a block diagram of the invention depicting multiple devices conn.oc~ecl in accordance with the invention; showing details of a partially interconnPcted mesh.
D~tqil~ nescru?tiorl of ~h~ Tnve~tion ~ IG. 1 conceptually illustrates multiple devices 10 fully interconl-~c~d in accordance with the invention. FIG. 1 illustrates five devices 10 com~;tcd together by ~licqted links 14 and 16. Those skilled in the art will recognize that different links 14 and/or 16 may support dirr~len~ bandwidths. Each of the devices 10 has the ability to c~.. ~ni~A~ with each of the other devices 10 and is connfc~ed to the network by four links 14. While the embodiment illustrated in FIG. 1 depicts five devices 10 each having four links 14, one skilled in the art 15 will recognize that this system can be applied to networks configured for more than five devices 10 or fewer than five devices 10, and that each of the devices 10 may have fewer than four links 14, four links 14, or more than four links 14. Additionally, FIG. 1 illu~l.ales a "full mesh" wll~.c~ every device 10 may directly co........ ~ni~q~e with every other device 10. It is also possible to configure the system as a "partial mesh" (i.e FIG. 2), wll~lcil1 certain devices 20 10 are not given the ability to co~ r~ directly with other devices 10.
FIG. 2 illustrates a system similar to the system illustrated in FIG. 1, wLcreill two devices 10 are not given the ability to directly co.. ~ with each other. Those skilled in the art, will recognize that the number of devices 10 which can not directly comml~ni~qte with each other may be greater than two. In the configuration illustrated in FIG. 2, it is possible 25 that the devices 10 may each have dirr.,.~." llulllbcl~ of links 14 (not shown) or that the devices 10 may have the same number of links 14, but with some of the links not being utilized (as shown in FIG.2).
It has been ~etermin~o~l that it is more economical and more efficient to utilize the configuration of the present invention when the llulllber of devices 10 to be connected is less 30 than or equal to one more than the number of links 14 on one device 10. Thus, with a backplane having M device slots to be employed by a network of devices, with M being a CA 022~34~ 1998-12-09 number greater than or equal to one, and each of the M device slots has N possible links 14, with N being a number greater than one, it has been determined that it is more economical and efficient to employ the present invention instead of a switch if M ~ N+ 1. It has also been determined that the present invention may be utilized for telephone networks, computer S nclwol~, colllbil~tions thereof and any other networks which require multiple devices 10 to comml-nir~te with each other (i.e. nclwolk hubs, network workstations, switches,Asynchronous Transfer Module-25 ("ATM-25"), low speed ATMs, cluster controllers,telephones, dirr.,lell~ telephony devices or the like). Various configurations of the present invention are possible which may provide dirr~,.elll qualities of service. One such configuration 10 is depicted in FIG. 2. FIG. 2 shows a configuration wllc.~hl the system does not provide a full mesh connection scheme between all of the devices 10. Thus certain devices 10 are not able to directly co.. ~ ate with certain other devices 10. Another such configuration could provide dirr~,~nL links 16, having dirf.,lelll bandwidths, to dirr.,.. l,l devices 10. Further, these configurations could be combilled, thus providing a partial mesh with different bandwidth 15 allocations. Further still, some links could have a higher pliolily associated th~ while others have a lower priority associated lL.,~e..~ . While these m~th~c have been disclosed, they are not meant to limit the present invention to any of these systems. The present invention will also work with no dirÇ.,.e.lliation in quality of service, with other quality of service techniques such as providing dirr.,.e,l- time slots for co.. ~ ;r~tion or other conventional 20- quality of service t~hniq~
One embodiment of the present invention may be imple...~ od on a conventional nc~wolk shelf (i.e. an ATM shelf. While an ATM shelf has been disclosed, it is not meant to be limiting in any way, the invention may be utilized on any other conventional shelf as well) (not shown). The ~lwol~ shelf may be used to support all or some of the devices 10.
The network shelf may also include a conventional backplane (not shown), which has multiple device ports. Since most conventional backplanes include at least one slot for a switch, a routing module 12 could replace the switch. In such a configuration, the routing module could have dedicated links 16 for providing dedicated communication paths bct~ all or some of the devices 10.
Another embodiment of the present invention may also be implem~ont~od on a conventional network shelf (not shown). The network shelf may be used to support all or some ofthe devices 10. The network shelf may also include a backplane 12 which has multiple device ports wherein all or some of the device ports have de~ic~t~ commnnic~tion paths (links) 14/16 therebetween. In such a configuration, it is llnn~cess~ry to include a port for a switch, although having one would not detract from the invention.
It will thus be seen that the invention efficiently attains the objects set forth above, among those made appare.lt from the prece~ling description. In particular, the invention provides a switchless network. Those skilled in the art will apple~iate that the configurations depicted in FIGS. 1 and 2 enable small ll~"be.~ of devices to co.,....~ ir~te efficiently and effectively.
It will be understood that changes may be made in the above construction and in the foregoing sequences of operation without depdl~ g from the scope of the invention. For example, those skilled in the art will recognize that not all of the ports on a backplane need to be involved in this d~ir~t~ connPction scheme. It is possible to have a backplane which only provides dedic~ted co.~.. ,lir~tion paths ~~ } certain of its device ports, while the 15 rem~ining device ports are co~ ~ to a conventional switch. If a red-ln-l~nry of links is desired, it is also possible that traffic may be routed through a second routing module to the destination module in case of a direct link failure. It is acco~l~gly int~n-~P.I that all matter cont~in~ in the above desc,il)lion or shown in the ~cco...l)~..yillg drawings be in~ eted as illustrative rather than in a limiting sense.
It is also to be understood that the following claims are int~n~ to cover all of the generic and specific fedlu.es of the invention as desc.ibed herein, and all st~tPm~nts of the scope of the invention which, as a matter of language, might be said to fall lllc~bclween.
Having described the invention, what is cl~im~d as new and secured by Letters Patent is:
