Data packet header conversion
First Claim
Patent Images
1. A method of converting a data packet from a first format compatible with a first network to a second format compatible with a second network, said method comprising:
- storing the data packet, wherein the data packet has a first header in the first format;
generating a header template having a plurality of static fields, the header template including, for an egress packet buffer, an IP header configured to be written to a first three quadwords of the egress packet buffer, an UDP header configured to be written to a fourth quadword of the egress packet buffer and an RTP header configured to be written to a fifth quadword of the egress packet buffer, the header template including, for an ingress packet buffer, a DSP header configured to be written to a fourth quadword and a fifth quadword of the ingress packet buffer;
generating at least one dynamic field; and
merging the header template with the first header and inserting the at least one dynamic field to form a converted header in the second format.

Abstract
A method of converting a data packet that has a header includes storing the data packet and generating a header template having a plurality of static fields. The method further includes generating at least one dynamic field and merging the header template with the header. The method further includes inserting the at least one dynamic field to form a converted header.

8. A method of converting a first data packet from a first format compatible with a first network to a second format compatible with a second network, comprising:
-
receiving the first data packet from the first network, the first data packet comprising a header having a plurality of fields in the first format; generating a header template having a plurality of static fields, the header template including, for an egress packet buffer, an IP header configured to be written to a first three quadwords of the egress packet buffer, an UDP header configured to be written to a fourth quadword of the egress packet buffer and an RTP header configured to be written to a fifth quadword of the egress packet buffer, the header template including, for an ingress packet buffer, a DSP header configured to be written to a fourth quadword and a fifth quadword of the ingress packet buffer; and merging the header template with the first data packet, wherein at least one of the static fields replaces at least one of the plurality of data packet fields. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to:
-
store a data packet, wherein the data packet has a first header in a first format compatible with a first network; generate a header template having a plurality of static fields, the header template including, for an egress packet buffer, an IP header configured to be written to a first three quadwords of the egress packet buffer, an UDP header configured to be written to a fourth quadword of the egress packet buffer and an RTP header configured to be written to a fifth quadword of the egress packet buffer, the header template including, for an ingress packet buffer, a DSP header configured to be written to a fourth quadword and a fifth quadword of the ingress packet buffer; generate at least one dynamic field; and merge the header template with the first header and insert the at least one dynamic field to form a converted header in a second format compatible with a second network. - View Dependent Claims (16, 17, 18, 19, 20, 21)
