Systems, apparatuses and methods for network packet management
Methods and systems are provided for latency-oriented router. An incoming packet is received on a first interface. The type of the incoming packet is determined. Upon the detection that the incoming packet belongs to latency-critical traffic, the incoming packet is duplicated into one or more copies. Subsequently, the duplicated copies are sent to a second interface in a delayed fashion where the duplicated copies are spread over a time period. The duplicated copies are received and processed at the second interface.
1. A method of managing data packets, the method comprising:
receiving, by a routing device, a plurality of packets from a computing device;
splitting, by the routing device, a first packet of the plurality of packets into two or more fragments;

transmitting, by the routing device, each fragment of the two or more fragments and the check-fragment to a target device, wherein the routing device comprises at least a first interface and a second interface each configured to communicatively couple the routing device to the target device, and wherein the routing device transmits at least a first fragment of the two or more fragments or the check fragment via the first interface and a second fragment of the two or more fragments or the check fragment via the second interface.
