implemented design. For example, automation in the sys-

tem can detect if a network engineer modifies an Access

Control List (ACL) that leaves certain systems vulnerable.

This integrated automation employs a series of probes and

watchdogs that revert the configuration to a properly func-

tioning state that is kept in the backend databases within

configurable intervals. Using the same example, changes to

ACL can be deployed to hundreds, if not thousands, of de-

vices with the click of a button. What makes this even more

powerful is that an engineer can input an ACL rule in a

single format once, and the automation platform can in turn

transform this rule, so that it can be enabled on a variety

of devices in a mixed-vendor environment. Thus, through

network automation and ZTP, operators can eliminate ven-

dor lock-in, increase adoption of new platforms, and reduce

overall network costs.



For organizations

building a global IP back-

bone, strategic PoP place-

ment and peering are essential

to gaining the best possible

performance and routing visibility.

With many choices of carrier-neutral

vendors and facilities available, orga-

nizations can plan their backbone and

network locations within close proximity of

nearly any network needed for interconnec-

tion. The benefits include direct peering with

major transit providers, Internet exchange points,

cloud service providers and direct cross connects

with customers, business partners, CDNs, etc.

When combining strategic PoP placement and

peering, organizations can effectivity shorten the cable

between their network and customers, along with any

networks needed for building resources, such as cloud

service providers and CDNs. As an example, a network

can be built in major markets on both coasts. On the East

Coast, PoPs built in the New York and Washington D.C. met-

ro areas offer many options for establishing peering to net-

works of choice. Likewise, adding PoPs in the San Francisco

Bay Area and Seattle are examples of West Coast coverage.

These locations can be interconnected with transport ser-

vices to complete the backbone for your organization.

Today, peering sessions can be built in each major metro

area of the backbone in order to announce networks that

can be locally served in those areas. This example essen-

tially shortens the path. Network services can be built and

replicated at each location, thereby increasing the likelihood
