Narrative:
N90/ZNY insisted that ZOB meter comply with times that were outside the limits defined in the service level agreement (sla) for metering operations to the new york market. Air carrier X was one of several aircraft that was spun at ZOB79 (jhw) when ZNY was not holding. ZNY and N90 were notified several times that the meter times were in excess of what ZOB had agreed to lose in the sla. They responded that they were at a 36 aar and we had to meet the times. The sector complexity at ZOB 79 was increased because of large meter times for ewr which was also being managed poorly. ZOB eventually turned tma off; but N90 continued to have ZNY; ZBW; and ZDC meter for them. ZOB tried on several occasions prior to tma failing; to explain to N90 that the settings they were using permitted the 44+ aircraft to arrive to no avail. Recommendation; support the freeze horizons with a gdp; use realistic tma settings.
