EIR-PIR-MBS-CIR-CBS

• EIR (Excess Information Rate)
• PIR (Peak Information Rate)
• MBS (Maximum Burst Size)
• CIR (Committed Information Rate): is the minimum guaranteed traffic delivered in the network.
• CBS (Committed Burst Size) is the flexibility of your provider, the maximum bytes allowed to exceed your CIR to be still CIR confirmed.

Committed Information Rate (CIR): CIR is the bandwidth or data rate guaranteed by an internet service provider (ISP) in a frame relay network. It represents the minimum data rate that the ISP promises to deliver consistently.

Excess Information Rate (EIR): EIR is the additional data rate beyond the CIR that an ISP may allow during non-congested periods. EIR provides the ability to burst above the CIR when network conditions permit, but without any bandwidth guarantee.

Comcast Router Configuration: Comcast customers with dedicated fiber circuits are responsible for configuring a router to manage the CIR and EIR appropriately. The router settings can impact the actual throughput experienced by the customer.

CIR (Committed Information Rate):

CIR refers to the minimum guaranteed bandwidth or data transfer rate that a service provider promises to deliver to a customer. With CIR, a customer can expect a consistent level of service, ensuring that a certain amount of bandwidth is always available regardless of network congestion or other factors.

Comcast Business may offer CIR as part of its service level agreements (SLAs) to ensure reliable and predictable internet performance for businesses. EIR (Excess Information Rate):

EIR represents the additional bandwidth or data transfer rate available beyond the CIR. This allows customers to utilize extra bandwidth when needed, especially during peak usage times or for bandwidth-intensive tasks.

Comcast Business might offer flexible EIR options to accommodate varying business needs and ensure optimal internet performance during high-demand periods.

When selecting a router for Comcast Business services with CIR and EIR, it's essential to choose a router that supports Quality of Service (QoS) features. QoS helps prioritize and manage network traffic, ensuring that critical business applications receive the necessary bandwidth and performance levels.

For specific router recommendations or detailed information about Comcast's CIR and EIR offerings, it's advisable to contact Comcast Business directly or visit their official website for the most accurate and up-to-date information tailored to your business requirements.
