The DilemmaThe Dilemma

“Defense community innovators have proposed concepts for using cutting-edge technologies to solve

long standing military challenges. These concepts assume great benefits from networking, however, the

advantages of networking as well as the implications of engineering distributed systems have not been fully

articulated.”

• Element– A physical component that performs a

certain function (includes humans and IT equipment)

• Connection– Any interaction between elements or

between elements and the external world (e.g., comm links, weapon-target pairings, or logical relations). May be via physical or non-physical interactions.

• Number of Elements and collective behavior– As N increases, complex behavior increases

• But overhead increases if C2 centralized– In RBN, N = 400-600 => tipping point

• Connection Strength– Defines rate and degree of response and adaptation

• Too strong = “synthetic epilepsy,” too weak = strong control signals

– Most DNS have a dynamic mix of strengths• Usually as a result of local trade-offs

• Diversity– Systems that best adapt to competitors and

environment have diverse elements and connections. • Up to a point

– Specialization and standardization (decrease in diversity) means adaptation is devalued; systems become more vulnerable to catastrophic failure in dynamic competition

• Scale – Scale is the extent to which the same system

looks different when observed at different levels of resolution. Very few dynamic, competing systems are “scale invariant”

– A distributed, networked system will be inefficient (or even completely ineffective) if it cannot observe, understand or influence behaviors at the scales in which they occur.

Design Goals“Universal Goods”

• Persistent Operational Advantage– Adaptively maintaining advantage against a clever

foe, even when facing surprising initiatives, dramatic innovations or changing rules. • Includes admitting disadvantage to regain persistent

advantage later.

• Competitive Collective Behavior– Acting as purposeful collectives without

prescribed, centralized control or synchronization. • An enemy’s ability to discern friendly intent will be

dramatically reduced if the macroscopic system actions are not mapped directly or obviously to the actions of the discrete elements.

Design Goals“Universal Goods”

• Stable System Performance– Dynamic competitive environments are extraordinarily

complex and unpredictable. A distributed, networked force must have a fundamental precept of stability in the midst of turmoil. • Controllable stability akin to "physical agility" plus aspects

of "balance." • Implies that limited losses should not impact macroscopic

behavior.

• Dynamic Adaptability– Branch-and-sequel planning is inappropriate for dynamic

environments but traditional long-term planning functions will still be required.• Simultaneously allocation, assessment and planning at

different time scales and in multiple dimensions.• Ability of forces to self-synchronize is imperative

An Intellectual Gap

• Physical parts of the system are over-represented in the Design Principles– Informational and logical aspects not at same level of

specificity as physical elements and tangible connections.

– Principles on the surface appear to concentrate on individual rather than collective attributes.

• Largely because sensibilities for designing intangible behaviors in distributed, networked forces are immature. – The practice of engineering distributed, networked

forces has not preceded the need to engineer such forces.

– We must develop the engineering and system engineering competencies for distributed forces at the same time that we learn how to engineer the actual forces.
