The DIA service offered by TWC supports both IPv4 and IPv6 addressing. Each TWC IP node consists of a full Internet routing table to ensure consistent and up to date IP destinations. With the full Internet routing table present at the first Layer3 hop outside the customer’s network, the customer is provided with the most efficient and accurate routing path to any and all destinations on the public Internet. Furthermore, the directly connected Layer3 router is fully redundant in terms of power, control plane, and core network uplink.
Time Warner Cable’s DIA service provides bi-directional, full duplex transmission of Ethernet frames using standard IEEE 802.3 Ethernet interfaces. The CIR is defined as the average bandwidth subscription rate available in megabits per second (Mbps) up to which service frames may be delivered. TWC’s Ethernet service supports bandwidth subscription rates starting at 10Mbps and increasing at 5Mbps increments up to 4Gbps. 10Gbps is considered on an individual case basis (ICB).
Time Warner Cable’s DIA service supports a Maximum Transmission Unit (MTU) packet size of 1500 bytes to support untagged packet sizes. All traffic will traverse the Time Warner Cable network infrastructure to the farthest point until it is required to be handed off to another Internet Service Provider.
