Abstract
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.

A method of managing packets, the method comprising:
- receiving, by a routing device comprising a plurality of interfaces, a first packet of a plurality of packets comprising a target address field and a source address field, wherein the routing device is communicatively coupled to a plurality of devices via the plurality of interfaces;
- generating, by the routing device, fragments based on the first packet, the fragments comprising at least a first fragment and a second fragment, wherein the fragments each comprise a subset of the first packet and whereby the first packet is capable of being reassembled from the fragments, and wherein the fragments each comprise a packet identifier field having a packet identifier associated with the first packet;
- generating, by the routing device, at least one fragment-copy of the first fragment, wherein the at least one fragment-copy of the first fragment comprises a packet identifier field having a same packet identifier as the first fragment;
- generating, by the routing device, at least one fragment-copy of the second fragment, wherein the at least one fragment-copy of the second fragment comprises a packet identifier field having a same packet identifier as the second fragment;
- and
- identifying, by the routing device, at least one characteristic of the first packet;
- determining, by the routing device, a first time period and a second time period based on the at least one characteristic;
- and
- transmitting, by the routing device, the first fragment, the at least one fragment-copy of the first fragment, the second fragment, and the at least one fragment-copy of the second fragment to a target device, wherein transmission of the at least one fragment-copy of the first fragment is delayed with respect to transmission of the first fragment according to a first time period and transmission of the at least one fragment-copy of the second fragment is delayed with respect to transmission of the second fragment according to a second time period.
