    "broadcast consists" is replaced by "broadcast address consists" and instead of saying that a switch delivers a copy of a broadcast packet to each computer on the network, the wording has been changed to clarify that a switch delivers a copy of a broadcast packet to each computer conected to the switch.

    The wording has been clarified to say that an application program does not need to change when the structure of the underlying Internet changes.

Page 60
    "views the each circuit" should be "views each circuit"


Page 82
    Section 5.1, "Unlike the original classless..." should be "Unlike the original classful...", and in Section 5.12 the "block of 32-N addresses" should be the block of 2^(32-N) addresses", and "address in the /21 range" should be "addresses in the /21 range". Also, "rounded to the nearest" should be "rounded up to the nearest"


Page 84
    The footnote has been changed to say that if a datagram with a private address reaches the global Internet, the datagram will be dropped.


Page 98
    The sentence "Each computer in a TCP/IP..." has been reworded to avoid implying that an IP address is assigned to a computer (an address is assigned to each network connection).


Page 114
    The sentence that refers to "the IP address being used" has been reworded to refer to the IP prefix being used on the two networks in the figure.


Page 115
    "specifies R's Ethernet address" should be "specifies "P's" Ethernet address.


Page 123
    The payload length in octets is the total datagram length minus the 4 times HLEN rather than thirty-two as stated.


Page 131
    A period is missing at the end of the sentece befor section 7.10.1, and "of next network" should be "of the next network".


Page 132
    The description of fragmentation and the reference to Figure 7.11 is unclear: the amount of data in a fragment is chosen to tbe the largest multiple of 8 octets that is less than or equal to the network MTU minus the IP header size. Also, "software on the host software" should be "software on the host".


Pages 211-212
    The segment TCP format in Figure 11.7 does not show the two code bits used for Explicit Congestion Notification, and Figure 11.8 does not list the purpose of the ECN bits. In addition, wording about acknowledgements in the first paragraph on page 211 has been clarified.


Pages 227-228
    The description of Excplicit Congestion Notification at the bottom of page 211 and top of page 212 does not explain the purpose of the two code bits in the TCP header that are related to ECN.


Page 294
    "To simply the example" should be "To simplify the example".


Page 304
    Address 224.0.0.6 should refer to OSPF Designated Gateways.


Page 305
    In Figure 14.9 and the description following, the field labale "SOURCE ROUTER IP ADDRESS" should be "ROUTER ID".


Page 308
    Text has been added to clarify that OSPF routers broadcast status when the boot, when changes occur, and periodically. The update message is named link state, not link status.


Page 309
    In Figure 14.14, the LS TYPE field should be split into an OPTIONS byte and LS TYPE byte. There are five possible formats, not four.


Page 310
    The text has been revised to say that the change from IP Address to Router ID occurred between the original OSPF and OSPFv2, not between OSPFv2 and OSPFv3.


Page 311
    "LSAa" should be "LSAs".


Page 327
    To be consist with the rest of the book, "The IEEE" has been changed to "IEEE"..
