Description

A SYSTEM TO DEPLOY QUALITY OF TRANSMISSION AND A METHOD THEREOF
FIELD OF THE INVENTION
The present invention relates generally to a system to deploy quality of transmission and a method thereof. More particularly, relates to a system to deploy quality of transmission wherein at least one packet is queued and scheduled based on a user assigned ratio of importance.
BACKGROUND OF THE INVENTION
Quality of Transmission (QoT) is becoming important to improve voice-over-IP (VoIP) quality. Existing inventions propose a mechanism to convert Internet Protocol (IP) multicast layer to Media Access Control (MAC) unicast layer by employing a translation module in an Access Device (AD). However, this mechanism does not cater for the Quality of Transmission (QoT) labeling associated with the incoming multicast packets. Therefore, any high priority multicast packet is simply treated as best effort packet on the outgoing queues of the AD.
US 7773602 B2 discloses a system for re-sequencing data packets including numbering data packets according to priority level of data packet and storing the data packet. US 20070133531 A1 discloses a packet forwarding apparatus including sorting pointer information according to priority and outputting the pointer information.
The prior art documents disclose priority based queuing and scheduling. Priority based scheduling only caters for the most important queue wherein the least important queues are delayed and starved. This may result in the packets sent by least important queue being stale due to the delay in sending the packets.
The prior art documents do not disclose ratio of importance queue and scheduling. Based on ratio of importance, the most important queue is given priority, at the same time the other queues also get to send their packets. Hence, aging and staling of the packets from least important queues is reduced.

DETAILED DESCRIPTION OF THE INVENTION
The invention and its various embodiments are better understood by reading the description along with the accompanying drawings which appear herein for purpose of illustration only and do not limit the invention in any way.
Figure 1 illustrates features of a module (10) wherein the module (10) is a multicast enhancement module. Incoming multicast packets are received by a first translator module (12) included in the module (10). The first translator module (12) is an incoming translator module. The incoming multicast packets are forwarded to a packet inspector (14) by the first translator module (12). The packet inspector (14) checks for priority marking. The packet inspector (14) sends feedback on priority marking to a packet marker (18). The multicast packets are forwarded to a first mapping module (16) by the first translator module (12). The first mapping module (16) includes a mapping table (17) wherein the mapping table (17) includes a Media Access Control (MAC) address of multicast subscribers of the multicast packets. The mapping table (17) is used to identify the MAC address of the multicast packets. The multicast packets are translated to MAC layer unicast packets by a second mapping module (20). The translated packets are forwarded to the packet marker (18). The packet marker (18) marks the translated packet based on feedback on priority marking received from the packet inspector (14) and forwards the packet to a second translator module (22). The second translator module (22) is an outgoing translator module.
Figure 2 illustrates features included in a Quality of Transmission (QoT) mechanism. An ingress module (30) receives the incoming multicast packets and forwards the packets to the module (10). The features included in the module (10) translate the multicast packets to Media Access Control (MAC) layer unicast packets and marks the packets. The second translator module (22) forwards the packets to a first queuing module (32). A first scheduler (34) picks the packets based on user assigned ratio of importance. The packets are checked wherein if the packets are not marked, a packet marker (36) re- mams tne pacKets. IT tne pacKets are already marked, tney are forwarded to a second queuing module (38). The re-marked packets are also forwarded to the second queuing module (38). The packets are queued in the second queuing module (38) using standard queues wherein the standard queues include but not limited to video, voice, best effort and background queue. A second scheduler (40) picks up the packets from the second queuing module (38) and forwards the packets through egress module (42).
Figure 3 illustrates a flow including Quality of Transmission (QoT) mechanism. Incoming multicast packets are received by the ingress module (30) of an access device (AD). The ingress module forwards the multicast packets to the first translator module (12) included in the module (10). The multicast packets are forwarded to the packet inspector (14) wherein the packets are extracted and checked for priority marking. The packet inspector (14) sends feedback on priority marking to the packet marker (18). The packet inspector (14) sends the packets to the first mapping module (16). The first mapping module (16) includes the mapping table (17) wherein the mapping table (17) includes a Media Access Control (MAC) address of multicast subscribers of the multicast packets. The multicast packets are translated to MAC layer unicast packets by the second mapping module (20). The second mapping module (20) forwards the translated packets to the packet marker (18). The packet marker (18) marks MAC layer unicast packets based on feedback on priority marking received from the packet inspector (14) and forwards the MAC layer unicast packets to the second translator module (22). The second translator module (22) forwards the MAC layer unicast packets to the first queuing module (32) based on ratio of importance. The ratio of importance is user assigned. The user may assign ratio of importance based on multicast address priority, source address priority or destination MAC address priority or any combination thereof. The first scheduler (34) picks the MAC layer unicast packets based on ratio of importance. The packets are checked wherein if the packets are not marked, the packet marker (36) re-marks the packets. If the packets are already marked, they are forwarded to the second queuing module (38). The re-marked packets are also forwarded to the second queuing module (38). The packets are queued in the second queuing module (38) using standard queues wherein the standard queues include but not limited to video, voice, best effort and background queue. The second scheduler (40) picks up the packets from the second queuing module (38). The second scheduler (40) forwards the packets through the egress module (42).
Figure 4 illustrates feature of ratio of importance included in queuing and scheduling MAC unicast packets. The MAC unicast packets are placed in the first queuing module (32) based on ratio of importance. The user may assign ratio of importance based on multicast address priority, source address priority or destination MAC address priority or any combination thereof. In an embodiment of the invention, the user assigns a 3:2:1 ratio of importance. The first scheduler (34) picks up three packets from a first queue, two packets from a second queue and one packet from third queue based on the ratio assigned. The scheduling is repeated until the first, second and the third queues are empty. If one of the queues is empty, the allocation of scheduling will be shared by the rest of the queues. The ratio of importance allows selectively fair network resource allocation where the less important traffic is given lesser access to the network but it is not totally starved.
