Method and apparatus for managing dynamic queue in broadcasting system
A method and an apparatus for adaptively coping with a network environment are provided. The method and apparatus includes a packet descriptor for forwarding of Media Transport (MMT) packets in a network process of a switch or a router for processing MMT packets forwarding content expressed in a structure of an MMT standard. The method of managing a queue in a broadcasting system includes receiving a Moving Picture Experts Group (MPEG) MMT packet, obtaining a header of the MMT packet, and queuing the MMT packet according to a type value of a bitrate included in the header of the MMT packet.
1. A method of managing a queue in a broadcasting system, the method comprising:
receiving a packet;
obtaining a header of the packet;
identifying whether a type value of a bit rate included in the header corresponds to a constant bit rate (CBR) or a non-constant bit rate (nCBR); and
queuing the packet according to the type value of the bit rate.
2. The method of claim 1 , wherein the header of the packet comprises a moving picture experts group (MPEG) media transport protocol (MMTP) header.
3. The method of claim 1 , wherein if the type value of the bit rate is a value indicating that the bit rate corresponds to the CBR, then queues are allocated such that a plurality of received packets have the same priority.
4. The method of claim 1 , wherein if the type value of the bit rate is a value indicating that the bit rate corresponds to the non-CBR, then queues are allocated in a reception order of packets.
5. The method of claim 1 , further comprising:
generating a packet descriptor according to an attribute value included in the header of the packet.
6. The method of claim 1 , further comprising:
identifying ports for which a link is damaged.
7. The method of claim 6 , further comprising:
freeing a packet buffer stored in a queue of a port determined to have a link that is damaged.
8. A non-transitory computer-readable storage medium storing instructions that, when executed, cause at least one processor to perform the method of claim 1 .
9. The method of claim 1 , wherein the packet includes a moving picture experts group (MPEG) media transport (MMT) packet.
10. An apparatus of managing a queue in a broadcasting system, the apparatus comprising:
a receiving unit configured to receive a packet;
a packet analyzer configured to obtain a header of the packet; and
a packet queue managing unit configured to queue the packet according to the type value of the bit rate,
wherein the packet analyzer is further configured to identify whether the type value of the bit rate included in the header corresponds to a constant bit rate (CBR) or a non-constant bit rate (nCBR).
11. The apparatus of claim 10 , wherein the header of the packet comprises a moving picture experts group (MPEG) media transport protocol (MMTP) header.
12. The apparatus of claim 10 , wherein if the type value of the bit rate is a value indicating that the bit rate corresponds to a CBR, then a queue is allocated such that a plurality of received packets have the same priority.
13. The apparatus of claim 10 , wherein if the type value of the bit rate is a value indicating that the bit rate corresponds to a nCBR, then queues are allocated in a reception order of packets.
14. The apparatus of claim 10 , wherein the packet queue managing unit is further configured to generate a packet descriptor according to an attribute value included in the header of the packet.
15. The apparatus of claim 10 , wherein the packet queue managing unit is further configured to identify ports for which a link is damaged.
16. The apparatus of claim 15 , wherein the packet queue managing unit is further configured to free a packet buffer stored in a queue of a port determined to have a link that is damaged.
17. The apparatus of claim 10 , wherein the packet includes a moving picture experts group (MPEG) media transport (MMT) packet.
