	English All status codes starting with digit `3` indicate that the requested document is no longer available on the server. `301 Moved Permanently` indicates that the requested document is no longer available on this server. A `Location:` header containing the new URI of the requested document is inserted in the HTTP response. `304 Not Modified` is used in response to an HTTP request containing the `If-Modified-Since:` header. This status line is used by the server if the document stored on the server is not more recent than the date indicated in the `If-Modified-Since:` header. 577/10000 · 577

55 ../../protocols/tcp.rst:192

	English When a TCP entity opens a TCP connection, it creates a Transmission Control Block (:term:`TCB`). The TCB contains the entire state that is maintained by the TCP entity for each TCP connection. During connection establishment, the TCB contains the local IP address, the remote IP address, the local port number, the remote port number, the current local sequence number and the last sequence number received from the remote entity. Until the mid 1990s, TCP implementations had a limit on the number of TCP connections that could be in the `SYN RCVD` state at a given time. Many implementations set this limit to about 100 TCBs. This limit was considered sufficient even for heavily load http servers given the small delay between the reception of a `SYN` segment and the reception of the `ACK` segment that terminates the establishment of the TCP connection. When the limit of 100 TCBs in the `SYN Rcvd` state is reached, the TCP entity discards all received TCP `SYN` segments that do not correspond to an existing TCB. 1019/10000 · 1019

	English If you want to observe the packets exchanged over the network, use a packet dissector such as `wireshark`_ or `tcpdump`_, listen the loopback interface (``lo``) and filter UDP packets using port 10000 (``udp.port==10000`` in `wireshark`_, ``udp port 10000`` with `tcpdump`_). 275/10000 · 275

	English The third technique to compute forwarding tables is to rely on a control plane using a distributed algorithm. Routers exchange control messages to discover the network topology and build their forwarding table based on them. We dedicate a more detailed description of such distributed algorithms later in this section. 318/10000 · 318

	English The two protocols above prevent eavesdropping attacks, but not man-in-the-middle attacks. If Mallory can intercept the messages sent by Alice, he could force her to reveal :math:`H^n(P)` and then use this information to authenticate as Alice on Bob's computer. In practice, hash chains should only be used when the communicating users know that there cannot be any man-in-the-middle on their communication. 406/10000 · 406

	English With the previous exercises, you have learned how to reason about IPv6 networks "on paper". Given the availability of IPv6 implementations, it is also possible to carry out experiments in real and virtual labs. Several virtual environments are possible. In this section, we focus on mininet_. mininet_ is an emulation framework developed at Stanford University that leverages the namespaces features of recent Linux kernels. With those namespaces, a single Linux kernel can support a variety of routers and hosts interconnected by virtual links. mininet_ has been used by several universities as an educational tool, but unfortunately it was designed without IPv6 support. 672/10000 · 672
