Packets must be like this

{id:'YOUR_ID', no:'PACKET_NUMBER' msg:'PACKET FROM CLIENT', timestamp:'DATETIME'}

A1 is a client. It runs client.sh. It creates 10 UDP4 and 10 TCP4 packets then if the packet is a udp4 packet, it sends to UDP45001 port. if the packet is a tcp4 packet, it sends to TCP45001 port. After sending packets it logs each of them to client.txt line by line.

Client.txt must be like this

CLIENT-->{PROTOCOL}: {MSG}{PACKET_NUMBER}{DATETIME}

A2 is a router. It runs route.sh. It listens on UDP4:5001 and TCP4:5001 ports. If incoming packet is a TCP4 packet, it sends to TCP4:20002 port. If incoming packet is a UDP4 packet, it sends to UDP4:10001 port then it logs each of incoming packet to route.txt line by line.

Route.txt must be like this

ROUTER-->PROTOCOL: [{MSG}{PACKET_NUMBER}{DATETIME}] {CURRENT_DATETIME}

A3 is a UDP4 server. It runs udpserver.sh. It listens on UDP4:10001 port and writes each of incoming packet to udplog.txt line by line.

Udplog.txt must be like this

UDP--> [{MSG}{PACKET_NUMBER}{DATETIME}] {CURRENT_DATETIME}

A4 is a TCP4 server. It runs tcpserver.sh. It listens on TCP4:20002 port and writes each of incoming packet to tcplog.txt line by line.

Udplog.txt must be like this

TCP--> [{MSG}{PACKET_NUMBER}{DATETIME}] {CURRENT_DATETIME}

Restrictions

• If there is no txt file, it will be created and overwritten if any. New log values will be written with each transaction.
• The symbols {,}, [,] in all messages will be preserved.
