Abstract

The invention relates to a device and a method which makes possible to automatically find out how much resources with regard to i.a. bandwidth that need to be allocated at a given flow of traffic in a telecommunication network and data communication network. The invention attends to this by building up a base of knowledge which makes possible optimization of booked resources in a packet-oriented communication network. Said base of knowledge is built up in two steps and is used after each step to automatically allocate necessary resources. A first measuring to adapt the maximal transmission rate of the terminal to the traffic intensity which the terminal generates includes measuring of least possible momentary consumption of resources for maximally allowed delay in the terminal. A second measuring to adapt allocated resources in the network to what the terminal generates for the whole duration of a given situation includes measuring of the traffic characteristics of the terminal and modification of allocated resources in the network on a statistical description of generated traffic.

SAMMADRAQ_A!_HBBElNNlNQEN Detta syfte uppnås med en anordning och en metod som anges i den kännetecknande delen av patentkravet l respekti- ve patentkravet 5.SAMMADRAQ_A!_HBBElNNlNQEN This object is achieved by a device and a method as set out in the characterizing part of patent claim 1 and patent claim 5, respectively.

De mätmetoder som ingår har verifierats genom laborato- rieprov för ett omfattande spektrum av IP-applikationer över ATM-nät.The measurement methods included have been verified through laboratory tests for a wide range of IP applications over ATM networks.

Mätmetoderna enligt uppfinningen har visat sig fungera mycket tillfredsställande vad beträffar att fastställa re- sursbehov i en abonnentterminal.The measurement methods according to the invention have proven to function very satisfactorily in determining resource requirements in a subscriber terminal.

Ytterligare kännetecken hos föreliggande uppfinning ges i underkraven.Further features of the present invention are given in the dependent claims.

D TA RIVNIN v EN " v I det följande ges först en generell beskrivning av hur terminalen och mätmetoden enligt föreliggande uppfinning fungerar. Därefter kommer en terminal och mätmetod att be- skrivas som är speciellt avsedd för ATM-nät.D TA RIVNIN v EN " v In the following, a general description of how the terminal and measurement method according to the present invention work is first given. Then, a terminal and measurement method will be described that is specifically intended for ATM networks.

Terminalen enligt uppfinningen är avsedd att bygga upp egen kunskap som möjliggör successiv optimering av bokade resurser i ett paketorienterat nät. Denna kunskap byggs upp i två steg och används efter varje steg för att automatiskt allokera resurserna: Först ombesörjer terminalen en inledande mätning för att anpassa terminalens maximala sändhastighet till den tra- fikintensitet som terminalen genererar för en given situa- tion. Mätningen sker i följande steg: 1. Mät minsta möjliga "momentana" resursåtgång för max- imalt tillåten fördröjning i terminalen. 2. Ställ in uppmätt sändhastighet i trafikformare. 3. Modifiera allokerade resurser i nätet till den sänd- hastighet som trafikformaren är inställd på.The terminal according to the invention is intended to build up its own knowledge that enables successive optimization of reserved resources in a packet-oriented network. This knowledge is built up in two steps and is used after each step to automatically allocate the resources: First, the terminal performs an initial measurement to adapt the terminal's maximum transmission rate to the traffic intensity that the terminal generates for a given situation. The measurement is carried out in the following steps: 1. Measure the lowest possible "instantaneous" resource consumption for the maximum allowed delay in the terminal. 2. Set the measured transmission rate in the traffic shaper. 3. Modify allocated resources in the network to the transmission rate that the traffic shaper is set to.

Därefter ombesörjer terminalen en fortsatt mätning för att anpassa allokerade resurser i nätet till vad terminalen genererar för en given situations hela varaktighet. Mätning- en sker i följande steg: ..-vv-w 10 15 20 25 30 35 40 anno ...nu 519 482V § 3 1. Mät terminalens trafikkarakteristik för "längre tids nyttjande". 2. Modifiera allokerade resurser i nätet baserat på en statistisk beskrivning av genererad trafik. 3. Lagra erhållna värden på både "momentan" och "längre tids nyttjande" tills nästa gång situationen upprepas för inställning av trafikformare och allokering av nätresurser.The terminal then performs a continued measurement to adapt allocated resources in the network to what the terminal generates for the entire duration of a given situation. The measurement takes place in the following steps: ..-vv-w 10 15 20 25 30 35 40 anno ...nu 519 482V § 3 1. Measure the terminal's traffic characteristics for "longer-term use". 2. Modify allocated resources in the network based on a statistical description of generated traffic. 3. Store the obtained values for both "instantaneous" and "longer-term use" until the next time the situation is repeated for setting traffic shapers and allocating network resources.

I det följande beskrivs en mätmetod som är specifik för ATM-nät.The following describes a measurement method that is specific to ATM networks.

Den inledande mätningen för att anpassa terminalens PCR (Peak Cell Rate) genererar för en given situation sker på följande sätt: till den trafikintensitet som terminalen 1. Mät minsta möjliga PCR för maximalt tillåten för- dröjning i bufferten till terminalens ATM-shaper (formare).The initial measurement to adapt the terminal's PCR (Peak Cell Rate) generation for a given situation is done as follows: to the traffic intensity that the terminal 1. Measure the smallest possible PCR for the maximum allowed delay in the buffer to the terminal's ATM shaper.

Fördröjningen kan t.ex. mätas genom applicering av den stan- dardiserade GCRA-algoritmen. 2. Ställ in uppmätt PCR i trafikformare. 3. Modifiera allokerade resurser i nätet till den PCR som trafikformaren är inställd på. Resursbehovet kan t.ex. meddelas med hjälp av standardiserade protokoll för signale- ring i ATM-nät.The delay can be measured, for example, by applying the standardized GCRA algorithm. 2. Set the measured PCR in the traffic shaper. 3. Modify allocated resources in the network to the PCR that the traffic shaper is set to. The resource requirement can be communicated, for example, using standardized protocols for signaling in ATM networks.

Fortsatt mätning för att anpassa allokerade resurser i nätet till vad terminalen genererar för en given situations hela varaktighet: 1. Mät terminalens trafikkarakteristik i termer av SCR (Sustainable Cell Rate) och MBS 2. Modifiera allokerade resurser i nätet i termer av SCR och MBS. 3. Lagra erhållna värden på PCR, SCR/MBS tills nästa gång samma situation upprepas.Continued measurement to adapt allocated resources in the network to what the terminal generates for the entire duration of a given situation: 1. Measure the terminal's traffic characteristics in terms of SCR (Sustainable Cell Rate) and MBS 2. Modify allocated resources in the network in terms of SCR and MBS. 3. Store the obtained values of PCR, SCR/MBS until the next time the same situation is repeated.

(Maximum Burst Size). Även om en situation i utgångsläget kan förefalla vara lika ett tidigare analyserat fall är det nödvändigt att kon- tinuerligt övervaka trafikformarens bufferttillstånd så att man kan justera resursallokeringen och därmed undvika för- sämrad tjänstekvalitet.(Maximum Burst Size). Although a situation may initially appear to be similar to a previously analyzed case, it is necessary to continuously monitor the buffer state of the traffic shaper so that resource allocation can be adjusted and thus avoid degraded service quality.

Uppfinningen används företrädesvis i abonnentterminaler i samband med förberedelsen för uppsättning av förbindelsen t.ex. ATM-nät eller IP-nät.The invention is preferably used in subscriber terminals in connection with the preparation for setting up the connection, for example, ATM network or IP network.

Det ovan nämnda är endast att betrakta som en fördel- över ett paketorienterat nät, aktig utföringsform av uppfinningen, och uppfinningens 519 482 4 skyddsomfáng definieras endast av vad som anges i de följan- de patentkraven.The above is only to be considered as an advantageous embodiment of the invention, and the scope of protection of the invention is defined only by what is stated in the following claims.
