Connectivity Costs Use Cases

The Connectivity Costs module helps you to understand the cost impact of traffic entering or exiting your network via external interfaces (i.e. transit and/or peering). The use cases for this module include the following:

  • Check the accuracy of billing statements from transit providers against your own traffic data.
  • Visually detect changes in cost, and drill down to understand the root cause of unexpected changes.
  • Expose current cost trends for use in network planning and forecasting.
    Note: In a future iteration you’ll also be able to surface historical cost trends across providers.

Connectivity Costs Concepts

The Connectivity Costs module is based on providers and cost groups:

  • Provider: A service provider that provides network connectivity services to customers (e.g. Century Link). In most cases a provider will correspond to a bill that you receive on a monthly basis.
  • Cost group: A set of interfaces that connect to a given provider and share a set of common billing characteristics:
    - A set of interfaces that share an aggregate bandwidth (“bundled”) corresponds to a single cost group.
    - Each interface that is metered independently (“unbundled”) corresponds to its own separate cost group.

Providers and cost groups are kept distinct to enable different ways of considering costs:

  • Providers often differentiate service costs based upon geography, offering one price for circuits in a certain part of the world but pricing those services differently in a different market.
  • A given provider may provide multiple types of services to the same user, e.g. a fixed cost transit circuit and also a circuit that is based upon a committed information rate.

By allowing you to define providers and to aggregate multiple cost groups, we enable you to see how much you’re spending with a given provider, regardless of the cost model (see About Cost Groups).

Connectivity Traffic Calculation

The estimation of your costs for connectivity (transit/peering) is based on calculations that we perform on traffic volume data collected via SNMP polling from the interfaces that you have assigned to a cost group (see Cost Group Interfaces). We use the following process to calculate traffic volume:

  1. Every data source whose interfaces will be included in the connectivity costs calculation must have SNMP polling enabled (see Enabling SNMP Polling), with the polling interval set to Standard (see SNMP Polling Intervals). We poll those interfaces and keep a record, at five minute intervals, of the increase in byte counter values, giving us a count of the bytes in and out during the interval.
  2. At a regular interval we use the stored bytes-per-interval data to calculate an in-rate and out-rate in Mbps for each five-minute interval.
  3. We then find the in-rate and out-rate at a given percentile of the rates calculated for all intervals since the start of the current billing period for the provider to which the interface is connected.
    - By default the percentile is 95th but it may be set to something else if the interface is part of a cost group that uses the Commit cost model (see About Cost Groups).
    - The billing period is specified in the Provider Details UI.
  4. We then calculate the rates stated in the portal:
    - The ingress or egress rate stated for a given interface in the Provider Interfaces Table is the rate found in the step above.
    - The ingress or egress rate stated for a given provider on the By Provider Page is the sum of the rates stated for each interface that has been associated with your cost groups for that provider (see Cost Group Interfaces).
    - The overall ingress or egress rate stated on the Connectivity Costs Page is the sum of the rates stated for every interface that has been associated with any of your cost groups.

Once we arrive at a projected traffic volume we use the costing information you provide in the Cost Group Details pane to estimate your current connectivity costs.

Enabling Connectivity Costs

To set up the Connectivity Costs module:

  1. Confirm that when you registered your network’s data sources (Setup » Data Sources) you permitted Kentik to poll your network interfaces via SNMP V2 or V3 (see Enabling SNMP Polling), with the polling interval set to Standard (see SNMP Polling Intervals).
  2. On the Connectivity Costs Page (Edge » Connectivity Costs), click the Configure button at upper right. You’ll be taken to the Configure Providers Page, where you’ll be able to add a new provider or edit the configuration of an existing provider.
  3. Click the Add Provider button at upper right. An Add Provider Card will appear above the list of existing providers, if any have been previously configured.
  4. In the Add Provider card, enter the provider’s Name and Type, as well as the start date of your billing cycle, then click the Save button. You’ll see a notice that the provider was added successfully, and you’ll be taken to the Provider Configuration Page for the new provider.
  5. On the Provider Configuration page, below the Provider Details pane, you’ll see a Cost Groups list containing a single cost group. Click the Edit button in this pane, which will take you to the Cost Group Page to set up your first cost group.
  6. On the Cost Group page, fill in the Cost Group Details pane.
  7. In the Cost Group Interfaces pane, click the Add Interfaces button. The Add Interfaces to Cost Group dialog will open, enabling you to add interfaces to the cost group (see Add Interfaces to Cost Group).
  8. When you’ve set both the details and interfaces for your cost group, click the Save button at bottom right. You’ll see a notice that the cost group was edited successfully, and you’ll be returned to the Provider Configuration page, where you can add additional cost groups as needed.
  9. When you’re done adding providers and cost groups, use the sidebar or the breadcrumbs at top to return to the Connectivity Costs page.

About Cost Groups

A cost group is a set of interfaces that share common values for a set of cost-related properties. The billing characteristics of a cost group depend on the group’s model, which is set in the Cost Group Details pane. Kentik currently supports the following models, which each involve selecting a bandwidth (bitrate) that you expect to send to or receive through a network provider:

  • Commit Cost Model: This model is based on the following elements (for details, see Commit Model Details):
    - A negotiated cost per megabit transferred.
    - A metered percentile, which allows you to briefly burst over the expected bitrate without causing the costs to increase.
  • Flat Rate Cost Model: In this model, the customer selects a bandwidth that they expect to send or receive through a network provider, expressed in terms of a bitrate. The customer negotiates a flat rate to send or receive that bitrate, but utilization is capped at the bitrate and the customer cannot burst beyond the bitrate. For details, see Flat Rate Model Details.

 

 
 top  |  section

Cost Group Details

The Cost Group Details pane is used to specify the properties of the cost group. Some properties are common to all cost groups while others depend on the group’s cost model.

 

Common Cost Details

The following cost-group details are displayed for all cost group models:

  • Name: The name that you give to a cost group.
  • Cost model: Commit or Flat Rate; see About Cost Groups.
  • Charges: Additional flat fees billed by this provider. See Charges Settings.

 

Charges Settings

Charges are additional flat fees billed by a provider. These charges, computed either annually or monthly, vary widely based upon contractual negotiation and business practices. For example, a flat rate contract that costs $5,000/month for 5 Gbps of connectivity over five 1 Gbit interfaces could be represented as a single monthly charge or as five individual charges of $1,000 each.

The following settings are used to configure charges:

  • Name: The name that you give to a charge.
  • Amount: The amount of the charge per period (month or year).
  • Frequency: The interval at which the charge will be assessed.
  • Remove charge: Delete the charge.

 

Commit Model Details

The following cost-group details are displayed only when the cost model is Commit:

  • Committed Information Rate: The bandwidth for which you are committed to pay the provider regardless of actual usage. This bandwidth is based on the larger of ingress traffic or egress traffic that you expect to send/receive over the interface(s) in the cost group.
    Example: If you expect egress traffic of 10 Gbps and ingress traffic of 40 Gbps, your committed information rate would be negotiated based on 40 Gbps.
  • Unit Price: The price, negotiated with the provider, by which traffic volume is multiplied to arrive at cost (exclusive of charges). The traffic volume is the greater of the actual utilization of the circuit (after accounting for the metered percentile) or the committed information rate.
  • Add Cost Tiers: An interface enabling you to create a tiered cost structure (see Cost Tiers UI).
  • Metered Percentile: The metered percentile enables a certain amount of traffic (traffic in excess of the stated percentile) to briefly “burst” past the committed information rate without triggering a financial penalty from the provider (see Metered Percentile Calculation). The percentile may be set from 90th to 99th depending on your contract with the provider.

 

Cost Tiers UI

Transit providers often base their charges on tiers, offering discounts for higher volumes of traffic. For example the charge may be $0.80 per megabit from 0-10 Gbps, $0.70 per megabit from 10-20 Gbps, $0.60 per megabit from 20-40 Gbps, and so on. As with an untiered cost model, the settings for the base tier (lowest traffic volume) are specified with the Committed Information Rate and Unit Price fields described in Commit Model Details. Additional (higher volume) tiers are implemented in cost groups using the Cost Tier form, which you can show/hide with the Add Cost Tiers button.

The Add Cost Tiers button opens a blank Cost Tier form with the following controls:

  • Bandwidth field: The upper bound of the new tier’s bandwidth as expressed in either Mbps or Gbps (20 Gbps in our example).
  • Unit selector: Choose Mbps or Gbps from the drop-down menu.
  • Rate field: The rate for the new tier (in our example the rate for 10 Gbps to 20 Gbps is $0.70).
  • Add Tier button: Adds a new tier with the settings above. As it each new tier is added it will be listed in the Cost Tiers List.

 

Cost Tiers List

The Cost Tiers list, which appears under the Cost Groups heading, is present whenever there is more than one tier defined for the cost group. The tier for lowest traffic volume will still be shown under Committed Information Rate, but the tiers that have been added to the cost group will each be represented as a row in the list. Each row includes the following UI elements:

  • Upper bound: The highest volume of traffic covered by the tier.
  • Rate: The charge per Mbps for traffic within the tier.
  • Remove: Removes the tier immediately (no dialog).

Notes:
- The lower bound of each tier is always the upper bound of the tier below.
- The rate applied to traffic in excess of the upper bound of the highest tier will be the same as the rate for the highest tier.

 

Metered Percentile Calculation

The metered percentile is calculated and applied as follows:

  1. Every five minutes (8,640 times per 30-day month), SNMP polling is used to determine two values related to the volume of traffic in each 5-minute period:
    - One for traffic entering the customer’s network from the provider’s network (ingress).
    - One for traffic leaving the customer’s network towards the provider’s network (egress).
  2. Within each category (ingress and egress) the per-interface values are ranked by volume and the value at the metered percentile (e.g. 95th) is determined.
    Note: If the group contains more than one interface, the ingress value is the sum of the per-interface ingress values and the egress value is the sum of the per-interface egress values.
  3. The ingress and egress values are compared and the lower of the two is discarded.
  4. The remaining (higher) value is used to calculate cost (exclusive of charges):
    - If the remaining value is less than the committed rate the cost is the committed rate times the unit price.
    - If the remaining value is more than the committed rate the cost is the remaining value times the unit price.

 

Flat Rate Model Details

The following cost-group detail is displayed only when the cost model is Flat Rate:

  • Bandwidth: The volume of traffic (in Mbps) you are paying the provider to carry via the interface or interfaces in the cost group (see Cost Group Interfaces).

 

 
 top  |  section

Cost Group Interfaces

The Cost Group Interfaces pane enables you to manage the interfaces in a cost group. Interface requirements depend on a cost group’s model:

  • Commit model: While an empty interface list is permitted in order to facilitate setup of the cost group, every cost group should contain at least one interface, and no calculations will be performed until the group contains an interface.
  • Flat rate model: Flat rate groups don’t strictly require interfaces (cost is calculated from charges), but adding interfaces will enable you to see how bandwidth consumption is distributed.

To add interfaces you’ll use the Add Interfaces to Cost Group button near the top of the pane, which opens the Add Interfaces to Cost Group dialog.

The Cost Group Interfaces pane also includes a table that details information about each of the interfaces included in the cost group. The table includes the following columns:

  • Interface: The name of the interface. Click to see interface details.
  • Device: The device on which this interface exists. Click to see device details.
  • Site: The site associated with the device on which this interface exists. Click to see site details.
  • Remove (trash icon): Delete the interface from this cost group.

 

Add Interfaces to Cost Group

Interfaces are added to a cost group via the Add Interfaces to Cost Group dialog, which you access via the Add Interfaces to Cost Group button on the Cost Group page. The dialog includes the following settings and controls:

  • Filter switches: Filter the list of available interfaces by the following criteria:
    - Provider: List only interfaces whose provider (see About Provider Classification) is the same as the provider in which this cost group exists.
    - Connectivity Type: List only interfaces whose connectivity type (see Connectivity Type Attribute) matches the Type setting in the Provider Details pane of the Provider Configuration Page.
    - Network Boundary: List only interfaces that connect to external networks (see Network Boundary Attribute).
  • Site: Use the drop-down to select a site. The list will be filtered to show only interfaces from that site.
  • Devices: Use the drop-down to select a device. The list will be filtered to show only interfaces on that device.
  • Search field: Enter text in the field. The list will be filtered to show only interfaces whose name, device name, or site name contains the entered string.
  • Interfaces list: A table listing all interfaces matching the above-listed filters (see Cost Group Interfaces List).

 

Cost Group Interfaces List

The table listing the interfaces associated with a cost group includes the following columns:

  • Interface: The name of the interface.
  • Device: The name of the device on which the interface exists.
  • Site: The site in which the interface exists.
  • Cost/month: The charges per month attributable to this interface.
