HOW TO PREPARE IP NETWORK INFRASTRUCTURE FOR THE 5G ERA<br />

VINCENTAS GRINIUS, CEO AT IPXO AND ZILVINAS VAICKUS, HEAD OF INFRASTRUCTURE AT<br />

IPXO, SHARE A FEW POINTERS TO KEEP IN MIND WHILE PLANNING A 5G MIGRATION STRATEGY<br />

The fifth-gen network brings with it<br />

immensely fast data speeds, however,<br />

it has a short-distance reach: the<br />

mmWaves 5G runs on span across only a<br />

few hundred metres. To cast a widespread<br />

net, a denser network of small cell towers<br />

that emit the necessary wavelength have to<br />

be set in place.<br />

For this reason, edge computing is also<br />

stepping into the limelight, in order to<br />

accommodate the need for faster data processing.<br />

With properly set up edge computing<br />

architecture, event processing happens<br />

in the edge node closest to the device.<br />

Consequently, resource-heavy devices can<br />

retrieve data at high speeds as it does not<br />

have to travel long distances to a cloud or<br />

a data centre.<br />

"Fifth-gen requires a tightly-knit network<br />

infrastructure. As speed and scale are<br />

imperative to the new wireless, the proximity<br />

of network components correlates with their<br />

capacity to process information at incredibly<br />

high levels," said Zilvinas Vaickus, Head of<br />

Infrastructure at IPXO.<br />

"Data centres as we know them will<br />

become an old story," Vaickus continued.<br />

"They will clear the way for densely-situated<br />

nodes, which will need to be implemented<br />

to provide the necessary agility in accordance<br />

with the next-gen network."<br />

ASSURING BACKLINK COMPATIBILITY<br />

IPv6 will have a major role to play in 5G,<br />

as IPv4 addresses, which are already in<br />

short supply, could never satisfy the evergrowing<br />

connection demand further down<br />

the road. That said, the majority of systems<br />

in place are IPv4-compatible only. To leverage<br />

in-house equipment alongside new<br />

standards for speed and data processing,<br />

implementing a dual-stack network with the<br />

capacity to process IPv4 and IPv6 traffic<br />

simultaneously becomes a crucial step<br />

when upgrading network architecture.<br />

"To think that with the coming of 5G and<br />

Internet Protocol 6 IPv4s would suddenly<br />

become irrelevant would be unrealistic,"<br />

explained Vincentas Grinius, CEO at IPXO.<br />

"Building an entirely new network of IPv6-<br />

only equipment would be too much of a<br />

grandiose aim that, for most, is not worth<br />

neither the time nor the investment. The<br />

simple truth is that there will always be systems<br />

compatible only with the previous<br />

protocol. Thus dual-stacking is a nonnegotiable<br />

integration when preparing for<br />

5G migration."<br />

Since IPv4 addresses will remain an integral<br />

part of the network, IP leasing platforms<br />

like IPXO will only grow in importance,<br />

as they will be able to lease out<br />

IPv4s necessary to ensure overall backlink<br />

compatibility among systems.<br />

WFH INFRASTRUCTURE CHALLENGE<br />

Although 5G technology is more robust and<br />

advanced compared to its predecessors,<br />

managing its security will not be an easy<br />

task to tackle. Addressing network vulnerabilities<br />

becomes an even more sensitive<br />

issue when you consider the increasing trend<br />

of remote working. As security executives try<br />

to wrap their heads around overseeing all<br />

the possible weak spots concerning the<br />

internal network, now they are obligated to<br />

look even further and define safeguards for<br />

remote workforce.<br />

"Fifth-gen supports a huge amount of connected<br />

devices. Consequently, this means<br />

there is a significantly larger number of possible<br />

access points to attempt to highjack,"<br />

commented Grinius. "While managing core<br />

network security remains the top priority, setting<br />

up a well-structured WFH infrastructure is<br />

definitely coming in as a close second in<br />

terms of preventing possible data breaches.<br />

Personal computers and networks often have<br />

fewer safeguards in place, and thus become<br />

an easy target for scammers."<br />

All in all, with the new generation rapidly<br />

approaching, the focus for most should<br />

remain not necessarily on the benefits 5G will<br />

bring to the table, but rather how to be better<br />

prepared to facilitate smooth integration with<br />

existing networks, ensure device compatibility<br />

and mitigate associated threats. NC<br />
