The following are snippets of Peering Policy Clauses found in the Peering Rules of the Road - A Brief Study of Peering Policies study.  Clauses were categorized and put into rough categories for comparison.

Here are the clauses we categorized as requirements for interconnect capacity, peering geographic diversity, and a clause indicating that both parties will peer in all locations in common.

Excerpts from Peering Polices

Minimum Interconnect Capacity

1.2.3 Minimum Interconnect: Requester shall have the ability to interconnect with AboveNet in a minimum of two geographically diverse peering locations where AboveNet has a peering point of presence. The peering Candidate must have the ability to interconnect directly at a minimum GigE (1000 Mbps) or greater capacity levels at each point of interconnection with a minimum utilization of 25%. – AboveNet, for Private Peering

Each Internet Network must establish and maintain traffic exchange links of a sufficient robustness, aggregate capacity, and geographic dispersion to facilitate mutually acceptable performance across the interconnect links. – Verizon

Each interconnection shall have no less than 1 Gbps of capacity. – InterNAP

Private Interconnects shall be done on one of the following interface types: GbE, 10GbE, STM-4, STM-16. – LambdaNet

Interconnection bandwidth for private peers must be at least 1 Gbps at each US interconnection point. – AT&T

Domestic Interconnection Requirements – multiple geographic locations

Speakeasy is primarily interested in peering with networks of similar size, where multiple geographically diverse interconnections are possible. – Speakeasy

Interconnection with other networks in a single location is possible under certain circumstances, such as:

    * to encourage adoption of newer technologies such as ip multicast, ipv6, or similar

    * peering with a network whose primary geographical footprint does not overlap that of Speakeasy's network infrastructure. examples of this could be national networks in Europe or Asia. – Speakeasy

ATDN

Peering capability: Applicant must peer with ATDN in at least four different locations in the US. Applicant must be able to interconnect with ATDN in:

    * DC area (Northern Virginia),

    * Middle of the country (Dallas or Chicago),

    * Bay area (San Jose/San Francisco),

    * New York or Atlanta.

Minimum interconnection speed is OC-12 (622 Mbps). All interconnections should be uniform speed.

For all interconnect types (Public and Private), interconnection must occur at a minimum of two (2) diverse peering points. For US peers, those interconnections must come from at least two (2) different geographic regions: East, Central, and West. Specific exemptions on the number of locations may be made, at Internap's discretion, for networks that operate in regions where Internap does not currently interconnect with other networks. – InterNAP

# tw telecom requires Non U.S. based ISPs to build peering sessions in at least 2 diverse regions on the coast where peering is initiated. – TW Telecom

Potential peers must be present in more than one common peering  location; RCN will not activate single-region peers.

[…]as long as the peer can meet us at both coasts as a minimum – HopOne

Presence at two or more Public Peering locations listed above (at least one on the West Coast and one on the East Coast or Mid West). – Cox

Presence at two or more Public peering locations listed above for International ISPs. – Cox

# Domestic networks must interconnect at a minimum of three physically diverse peering points, one in each of the following regions: West Coast (Los Angeles, San Jose or Seattle); Central (Chicago or Dallas); East Coast (New York, Ashburn, Philadelphia or Miami). – wbsconnect

# International networks may connect may interconnect at a single peering point: London, Amsterdam or Hong Kong – wbsconnect

# Peers must be able to support sessions in at least 3 different geographic regions or timezones (U.S. domestic networks). – Mzima

Applicant must meet Comcast at a minimum of four mutually agreeable geographically diverse points in the US. Interconnection points must include at least one city on the US east coast, one in the central region, and one on the US west coast, and must currently be chosen from Comcast peering points in the following list of metropolitan areas: New York City/Newark NJ, Ashburn, Atlanta, Miami, Chicago, Denver, Dallas, Los Angeles, Palo Alto/San Jose, and Seattle. – Comcast

All new peerings must be over private links. A minimum of two links interconnecting independent node-sets

is required. Substantial domestic traffic is expected to justify a link. – tinet

# Public Peerings shall be established on multiple locations. – LambdaNet

# Private Interconnects shall be backed by private or public interconnects in other physical locations. – LambdaNet

# Maintain a presence at two or more private peering cities listed above (at lest one on the West Coast, one on the East Coast and preferably on in the Mid West) for domestic ISPs. – NewEdge

Must be present in more than one common Public Peering location listed below (different time zones) – Charter

Interconnect: Interconnect Candidate will have the ability to interconnect with Qwest in a minimum of six geographically diverse Interconnection Points where Qwest has interconnection points of presence. The Interconnection Candidate must have the ability to interconnect directly at GE (1 Gbps) or greater capacity levels at each point of interconnection. – Qwest

Peer must meet AT&T at a minimum of three mutually agreeable geographically diverse points in the US. The US interconnection points must include at least one city on the US east coast, one in the central region, and one on the US west coast, and must currently be chosen from AT&T peering points in the following list of metropolitan areas: New York City/Newark NJ, Washington DC/Ashburn VA, Atlanta (for AS7018 only), Chicago, Dallas, Seattle (for AS7018 only), San Francisco/Palo Alto/San Jose, and Los Angeles. – AT&T

Peering at all points in common

Hurricane Electric expects you to peer at all exchange fabrics we have in common if we peer with you via public exchanges or all facilities we have in common if we peer via private interconnect with you. In other words, if are peering in the US, Asia and Europe at the same locations as Hurricane you must peer with Hurricane at all those locations. This is prevent problems for your and our US and European customers so that customer traffic does not cross the Pacific or Atlantic twice to return back to the same continent. – Hurrican Electric

tw telecom requires U.S. based ISPs to build peering sessions in as many locations as possible (California, Seattle, Chicago, Dallas, Atlanta, Ashburn, NY). – tw telecom

To ensure optimal QoS and redundancy, peers are requested to peer with us at all common peering points. – HopOne

Applicant agrees to peer in all markets where Peer and Tinet share a presence – tinet
