Abstract
In an embodiment, a computer-implemented method for preventing an Internet Protocol identifier (“IPID”) overflow in computer networks is disclosed. In an embodiment, the method comprises: receiving, by an edge service gateway, a first packet that requires fragmentating, and determining whether the edge service gateway is configured to prevent IPID overflow. In response to determining that the edge service gateway is configured to prevent IPID overflow, a plurality of packet fragments for the first packet is created based on, at least in part, contents of the first packet. A packet fragment, of the plurality of packet fragments, comprises an IP header, an additional header, and a portion of the first packet, wherein an additional key field in the additional header and an IPID field in the IP header of the packet fragment cumulatively store a packet sequence number for the first packet.
