  • f4805eded   [TCP]: fix congestion window update when using TSO deferal ... Browse Code »

    TCP peformance with TSO over networks with delay is awful.
    On a 100Mbit link with 150ms delay, we get 4Mbits/sec with TSO and
    50Mbits/sec without TSO.

    The problem is with TSO, we intentionally do not keep the maximum
    number of packets in flight to fill the window, we hold out to until
    we can send a MSS chunk. But, we also don't update the congestion window
    unless we have filled, as per RFC2861.

    This patch replaces the check for the congestion window being full
    with something smarter that accounts for TSO.

  • 6687e988d   [ICSK]: Move TCP congestion avoidance members to icsk ... Browse Code »

    This changeset basically moves tcp_sk()->{ca_ops,ca_state,etc} to inet_csk(),
    minimal renaming/moving done in this changeset to ease review.

    Most of it is just changes of struct tcp_sock * to struct sock * parameters.

    With this we move to a state closer to two interesting goals:

    1. Generalisation of net/ipv4/tcp_diag.c, becoming inet_diag.c, being used
    for any INET transport protocol that has struct inet_hashinfo and are
    derived from struct inet_connection_sock. Keeps the userspace API, that will
    just not display DCCP sockets, while newer versions of tools can support
    DCCP.

    2. INET generic transport pluggable Congestion Avoidance infrastructure, using
    the current TCP CA infrastructure with DCCP.

  • 835b3f0c0   [TCP]: Add TCP Hybla congestion control module. ... Browse Code »

    TCP Hybla congestion avoidance.

    - "In heterogeneous networks, TCP connections that incorporate a
    terrestrial or satellite radio link are greatly disadvantaged with
    respect to entirely wired connections, because of their longer round
    trip times (RTTs). To cope with this problem, a new TCP proposal, the
    TCP Hybla, is presented and discussed in the paper[1]. It stems from an
    analytical evaluation of the congestion window dynamics in the TCP
    standard versions (Tahoe, Reno, NewReno), which suggests the necessary
    modifications to remove the performance dependence on RTT.[...]"[1]
