a. Acceptable lit fiber based solution will include, but are not limited to, optical networking using wavelength-division multiplexing (WDM), Layer 2 Multi-Protocol Label Switching (MPLS) or Layer 2 Metro Ethernet. The proposal should clearly describe the type of service. b. Layer 2 (802.1q/802.1p) VLAN and QoS tags must be allowed through the provided network connection and must remain unchanged by the provider. c. Ethernet frames containing a 1500‐byte payload (for a total minimum supported Ethernet frame size of 1542 bytes), must be allowed and flow as a single complete frame without any fragmentation by the provider’s equipment. d. Protocols and network configurations including but not limited to, QoS, Multicast, Unicast, Layer 3 routing, Layer 2 (802.1q/802.1p) VLAN, 802.1ad provider bridging, VLAN will be passed through the provider untouched and delivered according to ANDS2. These services will follow open standards and industry best practices. e. Circuit performance must support jitter and latency sensitive applications and services including but not limited to, Video over IP, VOIP, and multi-Data Center Synchronous Applications. The included service level agreement should include the average jitter values and network latency between points within the network and the disclosure by what method these values will be calculated. For example, IETF standards for RTP such as RFC 3550 and RFC 3611 defines some methods such as Mean packet to packet delay variation, Mean absolute packet delay variation, Packet delay variation histograms and Y.1541 IPDV Parameter.
