Page 68: Decision: Sufficient Capacity
Page 68 of 302 IP Network engineering guidelines To complete this example, the traffic flow from the ITG node to all routes needs to be summed to determine the load to the link (T-LAN). Decision: Sufficient capacity? A link is defined as the route between the ITG Line 2.0 card node and a subnet.
Page 69: Set Service Parameters
IP Network engineering guidelines Page 69 of 302 Set service parameters Quality of Service (QOS) mechanism QOS is controlled by setting the DiffServ field in the IP header for both the ITG Line Card and the i2004 Internet Telephone. This can be set to a value between 0 and 255 using MAT 6.6/OTM 1.0.
Page 70 Page 70 of 302 IP Network engineering guidelines End-to-end delay and error characteristics of the intranet must be measured so that the technician can set realistic QOS expectations for intranet voice services. The use of measuring tools requires a starting node and a destination node. The starting node can be a “PING”...
Page 71 IP Network engineering guidelines Page 71 of 302 Both PING and traceroute are basic measuring tools that can be used to assess the ITG network. They are standard utilities that come with most commercial operating systems. PING is used to measure the round trip delay of a packet and the percentage of packet loss;...

Notice the variation of rtt from the PING output. It is from repeated sampling of rtt that a delay characteristic of the intranet can be obtained. In order to obtain a delay distribution, the PING tool can be embedded in a script which controls the frequency of the PING probes, timestamps and stores the samples in a raw data file.

Page 75 IP Network engineering guidelines Page 75 of 302 Late packets Packets that arrived outside of the window allowed by the jitter buffer are discarded by the ITG. To determine which PING samples to ignore, first calculate the average one-way delay based on all the samples. To calculate late packets, double the value of the nominal jitter buffer setting.
Page 76 Page 76 of 302 IP Network engineering guidelines At the end of this measurement and analysis, the technician has a good indication of whether or not the corporate intranet can deliver adequate voice service. Looking at the “Expected QOS level” column in Table 12 on page 75, the technician can gauge the QOS level for each site pair.
Page 77 To limit the size of this table, the packet loss and one-way delay values are tabulated in increments of 1% and 10ms respectively. The techniques used to determine and apply the information in this table are proprietary to Nortel Networks. Table 13 ITG QOS levels (Part 1 of 4)

Page 81 IP Network engineering guidelines Page 81 of 302 DiffServ/TOS The Type of Service (TOS) byte or Differentiated Service (DiffServ) code point determines the priorities of the management and voice packets in the ITG network. The range for both management and voice packet DiffServ/TOS is 0-255.
Page 82 Page 82 of 302 IP Network engineering guidelines To determine which links should be considered for upgrading, first list all the intranet links used to support the ITG traffic, which can be derived from the traceroute output for each site pair. Then, using the intranet link utilization report, note the highest utilized and/or the slowest links.
Page 83 IP Network engineering guidelines Page 83 of 302 The ITG Line 2.0 card node and the T-LAN router should be placed as close to the WAN backbone as possible in order to: • minimize the number of router hops. • segregate constant bit-rate Vo IP traffic from bursty LAN traffic.
Page 84 Page 84 of 302 IP Network engineering guidelines • LAN saturation. Packets may be dropped on under-engineered or faulty LAN segments. • Jitter buffer too small. Packets that arrive at the destination ITG, but too late to be placed in the jitter buffer are essentially loss packets. Adjusting jitter buffer size The jitter buffer parameters directly affect the end-to-end delay.

Page 282: Introduction To Dhcp
Page 282 of 302 Introduction to DHCP In order to understand how the i2004 Internet Telephone acquires the needed network configuration parameters automatically, the following section briefly describes the Dynamic Host Configuration Protocol (DHCP) protocol. It is recommended that readers, unfamiliar with the subject, read this section. Topics discussed will be helpful for the configuration and future maintenance of the DHCP server and ensure correct implementation with the i2004 Internet Telephone.
Page 283: Dhcp Messages
Page 283 of 302 DHCP messages There are seven different DHCP messages. Each message relates certain information between the client and server (see Table 2). Table 46 DHCP message types DHCP Message Types Description DHCPDISCOVER Initiates a client request to all servers. DHCPOFFER Offer from server following client request.
Page 284: Dhcp Message Exchange
Page 284 of 302 Figure 41 DHCP message format Refers to next bootstrap server Relay agent IP address DHCP Message Exchange For a client to receive services from a DHCP server, an exchange of DHCP messages between the client and server must take place. The sequence and types of DHCP message exchanged can differ, but the mechanism of acquiring and supplying information remains the same.
Page 285: Dhcp Options
Page 285 of 302 At this point, the client has no information about the server or the IP address it is going to receive (unless it is requesting a renewal), so the fields in the DHCP message are empty. However, the client knows its own MAC address and includes it in the Client hardware address field.
Page 286: Vendor Specific/Encapsulated Option
If the Vendor Encapsulation option is used, the information will have to first be encoded in a Site Specific option. Nortel Networks has provided a list of five possible Site Specific option codes to implement the ITG Line 2.0 card information.
Page 287: Ip Acquisition Sequence
Page 287 of 302 IP Acquisition Sequence This section focuses on the mechanics and sequence of the DHCP message exchange as the i2004 Internet Telephone uses DHCP for IP acquisition. Although the i2004 Internet Telephone requests many network configuration parameters as well as an IP address, the following cases focus on the concept of "how"...
Page 288: Case 2
Page 288 of 302 DHCPDISCOVER message. A DHCP server on the network sees the broadcast, reads the message, and records the MAC address of the client. It checks its own IP address pool(s) for an available IP address and broadcasts a DHCPOFFER message if one is available. (Usually the server ARPs or PINGs the IP address to make sure it is not being used.) The i2004 Internet Telephone sees the broadcast and after matching its MAC address with the offer, reads the rest of the message to find out...
Page 289: Case 3
Page 289 of 302 Figure 43 IP Acquisition Sequence - Case 2 Case 3 Finally, when a client is finished with a particular IP address, it sends a DHCPRELEASE message to the server which reclaims the IP address. If the client requires the same IP address again, it can initiate the process as follows: i2004 Internet Telephone broadcasts a DHCPREQUEST to a particular DHCP server by including the server's IP address in the Server IP...
Page 290: Multiple Dhcpoffers
The i2004 Internet Telephone only responds to DHCPOFFERs, that have the same unique string identifier, "Nortel-i2004-A" as the i2004 Internet Telephone. This string must appear in the beginning of the list of ITG Line 2.0 card parameters. Without this string, the i2004 Internet Telephone does not accept the DHPCOFFER, even if all parameters requested and ITG Line 2.0 card information are present.
Page 291: I2004 Support For Dhcp
DHCP DHCP support in the i2004 Internet Telephone includes sending a Class Identifier option with the value "Nortel-i2004-A" in each DHCP Discovery and Request. Additionally, the i2004 checks for either a Vendor Specific option message with a specific, unique to Nortel i2004, encapsulated sub-type, or a Site Specific DHCP option.
