PS4 Traffic Shaper to Decrease Latency and Increase Throughput
We've seen tips on Improving the PS4 Connection Speed, and recently developer Ssshoema made available a PS4 Traffic Shaper for TC (Traffic Control) QDISC (Queuing Discipline) network shaping to decrease latency and increase throughput on gaming consoles. 
Download: PS4-traffic-shaper-master.zip / GIT
From the README.md file, to quote: PS4 traffic shaper
Initially based on wondershaper 1.4 (The recent wondershaper version)
Goal 1 - Reduce gaming bufferbloat, prioritize PS4 console, and port priority for Destiny 2. Goal 2 - Not to block or "severely" minimalize traffic for the rest of LAN.
Using tc qdisc to shape the ingress and egress of network with prioritization on the PS4 gaming system and Destiny 2 game with port, TOS, ICMP, and <64 byte packet prioritization.
There are multiple methods available for network shaping so a google search may yield better solutions for traffic shaping in your case. This is not intended as an all encompassing solution. Mileage may vary for multiple reasons.
Setup for this implementation is a Linux gateway PC with 2 NIC's one facing the internet and the other facing my LAN. This shaping script is used on the internet facing NIC.
HTB/SFQ shaping in this instance was stable and was easily editable for fine tuning of classes, ports, and ingress/egress traffic. Again, there are multiple shaping algorithm possibilities which may provide better results.
Most scripts I studied were schemed towards a high priority, rest of traffic priority (medium), and low priority(non-desired traffic). This script classes are designed to not "squelch" any traffic but to tier traffic in such that my PS4, along with other high priority ip traffic that impacts gaming, is prioritized but all remaining network traffic does not nor is intended to suffer severely from the higher prioritization while the PS4 is in use (unless you want it to).
Port prioritization for PS4/Destiny 2 traffic is based on online port documentation and culling port information from IPTRAF during game play for the PS4 IP...

According to Kotaku.com, digital distribution including Vita PSN titles will continue for the time being with details below, to quote:
"Sony's American and European branches “plan to end all Vita GameCard production by close of fiscal year 2018,” the company told developers today in a message obtained by Kotaku.
The message asks that all Vita product code requests be submitted by June 28, 2018, and that final purchase orders be entered by February 15, 2019. Sony’s 2018 fiscal year will end on March 31, 2019."
