Video answer: What causes packet loss and how to eliminate it in your network
Top best answers to the question «Why packet can get reordered in network»
Out-of-order delivery can be caused by packets following multiple paths through a network, by lower-layer retransmission procedures (such as automatic repeat request), or via parallel processing paths within network equipment that are not designed to ensure that packet ordering is preserved.
Those who are looking for an answer to the question «Why packet can get reordered in network?» often ask the following questions:
💻 What is network packet?
A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network. Network packets are small (around 1.5 KBS for Ethernet packets and 64 KBS for IP packet payloads) amounts of data passed over TCP/IP networks.

💻 How packet flow in network?
There are simple rules for a packet flow in a network:
- If the destination host is present in the same network of the source host then the packet will be delivered directly to the destination host using MAC address.
- Within a network, the packet will be delivered on the basis of MAC address.

The first reason is the local parallelism within a packet router, which is a promising approach to build a high-speed and inexpensive packet router. Thus, packet reordering is more likely to occur in high-speed networks. The second reason is the load balancing among multiple links.
4. Packets can be fragmented and arrive out-of-sequence. The TCP stack which receives them should buffer and reorder them, before presenting the data as an incoming stream to the application layer. My problem is with message B, that I don't see because it's after the end of message one in the same packet.
The same reader did identify the probably cause for most packet reordering we see: packets from the same stream are queued differently, either due to different forwarding paths they take within a device or due to landing in different queues. Why would two packets from the same session land in different queues?
Packet switching is a method of transferring the data to a network in form of packets. In order to transfer the file fast and efficient manner over the network and minimize the transmission latency, the data is broken into small pieces of variable length, called Packet.At the destination, all these small-parts (packets) has to be reassembled, belonging to the same file.
Meaning the packets arrive in a different order then they're sent. These packets were originally dropped and now it appears as though they're reordering them inside of a buffer, assuming this also means that the buffer still can only hold so many packets before it will once again dump the packets if they arrive too late.
While your original question is about frame (L2) reordering, but now you added in a quote about packet (L3) reordering, specifically from an MPLS RFC. As I touched on in my answer, this is addressing tunneling Ethernet and how it should address the hard invariants (sequential delivery and non-duplication of frames).
A couple of thoughts from a network transport perspective: 1) Apart from a bad implementation or configuration or a bug of the hashing algorithm governing the load-balancing, can these days packet reordering still be introduced within an high-end router while traversing it's fabric layers from the input to the output port/card ?
Packets or ACKs could get reordered in the network. The sender should retransmit any packet for which it receives a duplicate ACK (i.e., an ACK it has received earlier). False.
Although according to (§2) it is still possible that your packets can get reordered if you send them back-to-back in under 20ms: 1st packet gets 100+10=110ms delay, 2nd packet that you send 1ms later gets 100-10=90ms delay; 2nd packet will arrive before 1st one.

What is packet data network (pdn)?
- In communications, a PDN is a circuit- or packet-switched network that is available to the public and that can transmit data in digital form.
What is packet data network system?
Packet headers are attached by certain types of networking protocols. A protocol is a standardized way of formatting data so that any computer can interpret the data. Many different protocols make the Internet work. Some of these protocols add headers to packets with information associated with that protocol.
What is the network packet size?
The network packet size option sets the packet size (in bytes) that is used across the whole network. Packets are the fixed-size chunks of data that transfer requests and results between clients and servers. The default packet size is 4,096 bytes.
What is the significance of packet size in a packet switching network?
The packet size is important because the network can then allow for flow control via a pre-determined 'window'. If there is a lot of PDUs travelling, the network can …
Can a corporate network run packet sniffers?
Therefore, network admins utilize packet sniffers on a corporate network to run diagnostics and to troubleshoot problems. Hackers now use packet sniffers to steal information and data from victims… Sometimes, packet sniffers can be used with other tools and programs for intercepting and manipulating packets.

Can a network coupler cause packet loss?
When working on a wired network, the Ethernet cables can be the reason that you are experiencing packet loss. These wires handle a lot of traffic, so if they have deteriorated, packet loss issues will occur and data will be sent inefficiently… Dirty fiber connectors are also a significant source of packet loss.
Can network ips use deep packet insepction?
Two primary types of products utilize deep packet inspection: firewalls that have implemented features of IDS, such as content inspection, and IDS systems that aim to protect the network rather than focus only on detecting attacks… IPS solutions – Some IPS solutions implement DPI technologies.

How does a packet switched network operate?
On a packet switched network, data travels between layers 1, 2 and 3 of the OSI model using routers (layer 3), switches (layer 2), and media (layer 1).
How does a packet switched network work?
Data communications network in which data is divided into small segments known as packets. These are divided so that each packet forms part of a complete message that can be routed through a network of switches to its destination independently of all other packets forming the same message.
