Clark, Scott Shenker and Lixia Zhang - "Supporting Real-Time Applications in an Integrated Services Packet - Network: Architecture and Mechanism". - - CBQ presents a flexible universal algorithm for packet scheduling, - but it has pretty poor delay characteristics. - Round-robin scheduling and link-sharing goals - apparently contradict minimization of network delay and jitter. - Moreover, correct handling of predictive flows seems to be - impossible in CBQ. - - CSZ presents a more precise but less flexible and less efficient - approach. As I understand it, the main idea is to create - WFQ flows for each guaranteed service and to allocate - the rest of bandwidth to dummy flow-0. Flow-0 comprises - the predictive services and the best effort traffic; - it is handled by a priority scheduler with the highest - priority band allocated for predictive services, and the rest --- - to the best effort packets. - - Note that in CSZ flows are NOT limited to their bandwidth. It - is supposed that the flow passed admission control at the edge - of the QoS network and it doesn't need further shaping. Any - attempt to improve the flow or to shape it to a token bucket - at intermediate hops will introduce undesired delays and raise - jitter. - - At the moment CSZ is the only scheduler that provides - true guaranteed service. Another schemes (including CBQ) - do not provide guaranteed delay and randomize jitter. - There is a proof (Sally Floyd), that delay - can be estimated by a IntServ compliant formula. - This result is true formally, but it is wrong in principle. - It takes into account only round-robin delays, - ignoring delays introduced by link sharing i.e. overlimiting. - Note that temporary overlimits are inevitable because - real links are not ideal, and the real algorithm must take this - into account. - - ALGORITHM. - - --- Notations. - - $B$ is link bandwidth (bits/sec). - - $I$ is set of all flows, including flow $0$. - Every flow $a \in I$ has associated bandwidth slice $r_a < 1$ and - $\sum_{a \in I} r_a = 1$. - - --- Flow model. - - Let $m_a$ is the number of backlogged bits in flow $a$. - The flow is {\em active}, if $m_a > 0$. - This number is a discontinuous function of time; - when a packet $i$ arrives: - \[ - m_a(t_i+0) - m_a(t_i-0) = L^i, - \] - where $L^i$ is the length of the arrived packet. - The flow queue is drained continuously until $m_a == 0$: - \[ - {d m_a \over dt} = - { B r_a \over \sum_{b \in A} r_b}. - \] - I.e. flow rates are their allocated rates proportionally - scaled to take all available link bandwidth. Apparently, - it is not the only possible policy. F.e. CBQ classes - without borrowing would be modelled by: - \[ - {d m_a \over dt} = - B r_a . - \] - More complicated hierarchical bandwidth allocation - policies are possible, but unfortunately, the basic - flow equations have a simple solution only for proportional - scaling. - - --- Departure times. - - We calculate the time until the last bit of packet is sent: - \[ - E_a^i(t) = { m_a(t_i) - \delta_a(t) \over r_a }, - \] - where $\delta_a(t)$ is number of bits drained since $t_i$. - We have to evaluate $E_a^i$ for all queued packets, - then find the packet with minimal $E_a^i$ and send it. - - This sounds good, but direct implementation of the algorithm - is absolutely infeasible. Luckily, if flow rates - are scaled proportionally, the equations have a simple solution. - - The differential equation for $E_a^i$ is - \[ - {d E_a^i (t) \over dt } = - { d \delta_a(t) \over dt} { 1 \over r_a} = - { B \over \sum_{b \in A} r_b} - \] - with initial condition - \[ - E_a^i (t_i) = { m_a(t_i) \over r_a } . - \] - - Let's introduce an auxiliary function $R(t)$: - - --- Round number. - - Consider the following model: we rotate over active flows, - sending $r_a B$ bits from every flow, so that we send - $B \sum_{a \in A} r_a$ bits per round, that takes - $\sum_{a \in A} r_a$ seconds. - - Hence, $R(t)$ (round number) is a monotonically increasing - linear function of time when $A$ is not changed - \[ - { d R(t) \over dt } = { 1 \over \sum_{a \in A} r_a } - \] - and it is continuous when $A$ changes. - - The central observation is that the quantity - $F_a^i = R(t) + E_a^i(t)/B$ does not depend on time at all! - $R(t)$ does not depend on flow, so that $F_a^i$ can be - calculated only once on packet arrival, and we need not - recalculate $E$ numbers and resorting queues. - The number $F_a^i$ is called finish number of the packet. - It is just the value of $R(t)$ when the last bit of packet - is sent out. - - Maximal finish number on flow is called finish number of flow - and minimal one is "start number of flow". - Apparently, flow is active if and only if $F_a \leq R$. - - When a packet of length $L_i$ bit arrives to flow $a$ at time $t_i$, - we calculate $F_a^i$ as: - - If flow was inactive ($F_a < R$): - $F_a^i = R(t) + {L_i \over B r_a}$ - otherwise - $F_a^i = F_a + {L_i \over B r_a}$ - - These equations complete the algorithm specification. - - It looks pretty hairy, but there is a simple - procedure for solving these equations. - See procedure csz_update(), that is a generalization of - the algorithm from S. Keshav's thesis Chapter 3 - "Efficient Implementation of Fair Queuing". - - NOTES. - - * We implement only the simplest variant of CSZ, - when flow-0 is a explicit 4band priority fifo. - This is bad, but we need a "peek" operation in addition - to "dequeue" to implement complete CSZ. - I do not want to do that, unless it is absolutely - necessary. - - * A primitive support for token bucket filtering - presents itself too. It directly contradicts CSZ, but - even though the Internet is on the globe ... :-) - "the edges of the network" really exist. - - BUGS. - - * Fixed point arithmetic is overcomplicated, suboptimal and even - wrong.
