Bandwidth limits may be defined for any connection up to the total limit of the connection (either a singe wireless connection or up to 4 wireless connections with HotPools). Input, output and total limits may be defined for any connection. Bandwidth limits may be further refined based on the Time of Day. A bandwidth of 0 can be used to deny connection at certain times and is typically only used with Time of Day features.
It is possible to limit and control bandwidth supplied from 0 to 4.8M and by Time of Day or Day of Week or both.
Air-Frame routers may operate in 'stand-alone' mode in which case they will have a single wireless connection.
Air-Frame may also be configured to operate in 'HotPools' mode in which case multiple routers and wireless links are combined to create 'bigger links'. In 'HotPools' mode multiple routers (the Pool) will act together as a single entity to create a total bandwidth equal to the sum of all the available links i.e. 2 routers will have 2 wireless connections providing 2.4M bits per second, 4 routers will have 4 connections or 4.8M bits per second.
Bandwidth needs may vary radically with time. Daytime browsing needs may be higher than overnight FTP loads. The user may not require any bandwidth after 6PM. Web and FTP site utilization may increase dramatically during another time zone's daytime usage.
The user may define the bandwidth properties using three Time of Day slots per Physical Route based on the Day of the week (DoW) or Time of Day(ToD) or both. As with all parameters this is controlled via the SNMP MIB (or Web interface) and can be changed in real-time without service interruption.
The Route properties define how each 'end' of a connection sees that connection. Air-Frame can be configured to use a simple arbitration rule. If an incoming connection is made it is assumed that the other end (the initiator) knows what it is doing - so it controls the Connection. This simple concept can allow significant efficiencies of usage and remove the need for time consuming and inflexible bandwidth negotiation schemes. It further allows control to reside on one end of the link or for both ends to co-operate.
This is particularly useful where you want to control who adds capacity but you want both 'ends' to be able to create a minimal link. In, say, an ISP connection you may want the service provider to be able to provide up to 256K of outgoing capacity in burst mode but the clients has a fixed limit of 128K incoming.
The user e.g. ISP can establish any number of HotPools e.g. a Pool of 128K connections, a Pool of 384K connections. Each Router is configured to join a specific Pool (an arbitrary Pool number) at which point it exchanges configuration information with all other routers in that Pool and thus the Pools topology and resources are known to all other members of the Pool. As with all parameters this is controlled via the SNMP MIB and can be changed in real-time without service interruption.
The user may define the bandwidth properties using three Time of Day slots based on the Day of the Week, Time of Day or the Type of Day (week day, week-end). It is possible to define a usage pattern providing 256K from 8am to 5pm and 128K overnight or 2 wireless links from 7AM to 6PM Monday to Friday and 0 connections at any other time, or 512K continuously or any other combination. As with all properties this is controlled via the SNMP MIB and can be changed in real-time without service interruption.
The user may define the bandwidth properties using three Time of Day slots per Route each slot runs until completion at which time it is superseded by the next slot that meets the criteria e.g. it is 5PM Sunday. Using 3 ToD slots provides endless permutations to reduce costs and/or add dynamic capacity to satisfy demand. As with all parameters this is controlled via the SNMP MIB and can be changed in real-time without service interruption.
Setting a Time of Day slot with a 0 bandwidth property causes the system to shut down completely at the end of the first Idle Timer period in the new ToD slot. This feature allows users to safely leave computers switched on and not worry about 'dirty web sites' continually refreshing displays (consuming time and money). As with all parameters this is controlled via the SNMP MIB and can be changed in real-time without service interruption.
The user can 'temporarily' open a 0 bandwidth connection. The link is opened for the time period specified and then reverts to its original schedule. Service providers may want to apply premium charges for this type of flexibility.
