Compania Intel a lansat un set de instrumente care permit crearea de aplica\u021bii proprietare pentru procesarea pachetelor \u00een comutoare Ethernet programabile din seria Tofino. Codul surs\u0103 al back-end-ului pentru compilatorul p4c \u0219i al componentelor mediului de dezvoltare Intel P4 Studio, cum ar fi driverele, modelul de simulare a comutatorului, serverul \u0219i clientul pentru protocolul BF Runtime, a fost deschis sub licen\u021ba Apache 2.0. Pentru crearea aplica\u021biilor se folose\u0219te limbajul de programare orientat pe domenii P4 (Programming Protocol-independent Packet Processors), destinat definirii logicii de procesare a pachetelor \u00een dispozitivele de re\u021bea, cum ar fi pl\u0103cile de re\u021bea, comutatoarele, routerele \u0219i firewall-urile. <\/p>\n

Back-end-ul publicat permite transpunerea programelor \u00een limbajul P4 \u00eentr-o reprezentare adecvat\u0103 pentru instalarea pe comutatoarele din seria Intel Tofino. Datorit\u0103 acestui lucru, utilizatorii comutatoarelor pot crea aplica\u021bii care extind func\u021bionalitatea standard, modific\u0103 logica de operare sau adapteaz\u0103 dispozitivul la specificul re\u021belelor lor. <\/p>\n

Programele \u00een limbajul P4 sunt compilate \u00een reprezent\u0103ri pentru platformele \u021bint\u0103, care pot fi at\u00e2t hardware (FPGA, ASIC-uri programabile), c\u00e2t \u0219i software (x86, BPF). \u00cempreun\u0103 cu codul pentru instalarea pe sistemele \u021bint\u0103, compilatorul genereaz\u0103 un runtime pentru gestionarea aplica\u021biei folosind protocoale Protobuf\/gRPC \u0219i API P4Runtime. <\/p>\n

Logica standard de func\u021bionare a programelor se reduce la clasificarea pachetelor pe baza antetelor lor \u0219i la executarea ac\u021biunilor asupra pachetelor de intrare, cum ar fi redirec\u021bionarea, abandonarea, modificarea TTL \u0219i \u00eenlocuirea c\u00e2mpurilor. Limbajul nu este legat de protocoalele de re\u021bea \u0219i, \u00een loc de suportul \u00eencorporat pentru protocoale standard, cum ar fi IP, Ethernet, TCP \u0219i VxLAN, ofer\u0103 dezvoltatorilor posibilitatea de a defini orice protocoale legate de aplica\u021biile compilabile (dezvoltatorul ata\u0219eaz\u0103 descrierea formatelor antetelor \u0219i c\u00e2mpurilor protocolului).

\"A<\/center> <\/p>\n

Pe l\u00e2ng\u0103 back-end-ul publicat pentru comutatoarele Intel Tofino, proiectul P4 ofer\u0103 un back-end pentru compilarea aplica\u021biilor P4 \u00een cod C, care poate fi apoi compilat \u00eentr-un format potrivit pentru execu\u021bie \u00een ma\u0219ina virtual\u0103<\/a> eBPF \u00een interiorul nucleului Linux. Proiectul dezvolt\u0103, de asemenea, un simulator deschis pentru comutator, care poate fi folosit pentru experimente \u00een re\u021beaua virtual\u0103 Mininet, \u0219i un back-end pentru compilarea programelor P4 pentru simulator.
