Shareband introduce Bonding ADSL Lines at IP Level
Sharedband enables a single stream of data to utilise the full aggregated upstream and downstream capacity.
Application agnostic -- able to handle applications from voice to video.
Supports multiple protocols including TCP, UDP, ICMP, PPTP over GRE, and IPSEC over UDP and TCP.
* (IPSEC over L2TP is currently under development)
Supports static and shared IP addressing with Network Address Translation (NAT) and Port Address Translation (PAT)
External IP and port addresses mapped from IP ranges allocated to the aggregation servers to local IP / port addresses on the customers LAN
In the event of an individual router failure there is a transparent gateway failover which is enabled using the VRRP set up. Sharedband also supports DHCP server failover.
Sharedband software is suitable for working with most types of broadband connections. The current version of upgrade firmware is available for the following supported devices:
* Netgear ADSL modem router, DG834 v2 and v3
* Netgear wireless ADSL modem router DG834g v2 and v3
* Linksys wireless router WRT54GL
Sharedband is packet based technology and MLPPP (multi link point to point protocol) is not required for shared bandwidth resource pooling.
Sharedband is suited for a single deployment on up to four IP connections. The software tests the actual lines speeds at periodic intervals to optimize the distribution of the packets and provide the best aggregated performance.
For optimal performance the lines should have similar latencies, not more than 20ms between the slowest and fastest round trip times. Future versions of Sharedband will include a packet resequencing feature that will manage connections with widely different latencies.
